    Managing Problems and Complications

    Last time we talked about occlusal problems. This lecture summarizes pinpoints

    of problems that could arise. There isnt much explanation about the problems

    because they are related to your understanding of the occlusal schemes for the

    complete denture.

    Problems in Occlusion

    Uneven Initial Contact

    It causes dentures to tilt on supporting tissues, thus disrupting retentive seal. Also prevents

    even seating of loosening dentures on supporting tissues when teeth occlude.

    Recognizing: You ask the patient to close slowly into RCP until teeth just

    touch.

    Management: Aim is to adjust occlusion until even contact in RCP is

    achieved.

    Minor errors: use chair side techniques- difficult as dentures move on

    supporting tissues producing errors in markings.

    Major errors: use laboratory techniques. Remount the maxillary

    denture on a semi adjustable articulator using a face bow and the

    Mandibular denture with Pre-tooth contact registration. Then adjust the

    occlusion on the articulator using articulating paper.

    Gaps more than 1.5mm (vertically) or errors in anterio-posterior

    relation more than half a cusp cannot be adjusted by selective grindingand requires re-setting.

    We said in the occlusal scheme lecture that for the complete dentures to be stable in the

    patients mouth we must have balanced articulation; balanced contacts on both sides which

    differs from natural teeth. In natural teeth there are teeth and bone, so there is canine guidance

    or group function on one side (working side) and all teeth are out of occlusion on the other side.

    You stick to that rule when you do a crown, a bridge or a partial denture. But as for the

    complete denture, it is not anchored in the patients mouth, its just setting there. So if theres

    group contact on one side, the denture will flip because there will be displacement forces on the

    denture. So if there is uneven contact that will lead to displacement.

    How do you manage that?

    Usually on the insertion visit -or if it wasnt your work and the patient wants to review his

    dentures- you can check the contacts by using articulating papers. You hold the dentures in

    place and ask the patient to close on the articulating paper. If there is uneven contact, it will be

  • 8/13/2019 Prost Ho Don Tics 10

    2/15

    2 Managing Problems & Immediate Dentures| Prosthodontics

    apparent. Adjust these contacts if the error is minor. In major errors you have to do a remount

    procedure. The remount procedure is simply making a facebow transfer in the upper denture,

    you make a precentric (just before centric) wax record, you put wax between the teeth and ask

    the patient to close until teeth just meet, you must stop the patient from forceful closure, we

    dont want the patient to close forcefully so that the dentures move and the teeth set into

    intercuspal position, because if the dentures are not stable and he closes his mouth forcefully,

    the dentures will be stabilized, but we actually have an error in occlusion. After that the

    technician pours the upper and the lower dentures now he has a cast with the registration. He

    mounts it on the articulator, and then he adjusts the occlusion. The technician might have to

    reset the posterior teeth. So he removes them and he puts a new wax rim with another bite

    record, occlusal registration, try-in and another insertion. This is very common in the clinic. One

    of the errors done by a dentist is that he holds the mandible in the registration closed. Now if

    the baseplate wasnt stable, especially if there is uneven pressure on the wax rim, the

    baseplates will not be seated properly so it will seem that the registration wax is even and you

    will see that the lower denture is raised a bit (the lower is raised mostly), so when the patient

    closes it flips. The try-in also doesnt work, you put them on each other and you think that the

    contact is even and excellent, but on the insertion visit you will notice a gap, because on

    insertion the denture will be more stable or it will look like that so you have to check the

    occlusion. On insertion or registration you have to hold the baseplate in place then ask the

    patient to close slowly until the teeth just meet, it will show if theres an error in occlusion or

    not. When the teeth meet forcefully it might cause flipping or they may get into nice occlusion

    so it will give you the false impression. A very common mistake in the registration stage is that

    you didnt hold the denture. You should use adhesive to make sure that the baseplate is fully

    seated on the ridge. When I do it myself I usually support the upper and the lower dentures,

    keep them in place and ask the patient to close while holding the baseplate, the lower on the

    lower ridge and the upper on the upper ridge. This is my technique I hold the baseplate

    forcefully seating it properly in its place to avoid this problem, because if I leave it as it is, the

    wax rims will never meet evenly, and it will flip.

    Lack of freedom between RCP & ICP

    Patient with inaccurate control of Mandibular movement may not adapt to exact cusp-fossa

    relationship causing dentures to move and disrupt the peripheral seal.

    Recognizing: Age/ medical history: the patient has difficulty in achieving reproducible occlusal

    relationship. The patient is able to eat using old dentures with flattened, worn teeth.Management: Remount dentures and adjust teeth to produce area of freedom. If adjustment

    will result in loss of occlusal balance, reset/remake using cuspless teeth.

    Avoidance: Always allow 1-1.5mm of easy anterior movement of mandible from RCP.

    Consider use of cuspless teeth (non-anatomic) teeth, set in occlusal balance during lateral and

    protrusive movement (this produces no vertical overlap- possible effect on aesthetics)

  • 8/13/2019 Prost Ho Don Tics 10

    3 Managing Problems & Immediate Dentures| Prosthodontics

    You use cuspless teeth with a patient that has difficulty adapting into RCP, because of muscular

    problems or because he has been using a denture for a long time. You have to give those

    patients freedom between the RCP and ICP. If you give your patient one RCP locked into that

    position, he cannot afford that. You have to adjust that and give him a little bit of freedom. If

    you cant do it chairside, you must do a remount procedure. You can avoid that by careful

    assessment of the medical problem and by using non anatomical teeth.

    Lack of occlusal balance in excursive movements

    It causes dentures to shift on supporting tissues and disrupt retentive seal. Many patients wear

    dentures successfully without occlusal balance, however, as retentive forces decrease,

    displacing forces generated by lack of balance assume greater significance.

    Recognizing: Hold the dentures in place on the supporting tissues. Request the patient to close

    until his teeth just touch, then to rub from side to side and forwards. By observation, note teeth

    slide easily without causing dentures to move over supporting tissues.

    Lack of balance is commonly associated with excessive vertical overlap of anterior teeth.Management: Adjust teeth until balanced contacts are achieved. Could be done chair side, but

    remount procedure is preferred. If achievement of balancing contacts would necessitate

    mutilation of teeth (excessive shortening of lower incisors), then reset teeth or remake

    dentures.

    If theres lack in occlusal balance (not just in centric, left and right, theres no balanced

    occlusion) you could adjust that chairside or in the laboratory. You recognize that problem by

    holding the denture in place and asking the patient to close until his teeth just meet, and then

    rubbing the teeth left and right, then you can visualize any major errors and you can use the

    articulating papers to mark these areas and adjust them chairside or in the lab.

    Excessive vertical overlap of anterior teeth

    Recognizing: Detection of interferences during speech: request the patient to produce the S

    sound. Upper and lower teeth should not touch.

    Management: Shorten the lower anterior teeth; this may result in an aesthetic problem.

    If up to 1.5mm of free way space is required, remount and selectively alter occlusal contacts to

    reduce vertical dimension at occlusion. If the extra freeway space required exceeds 1.5mm,

    remove the posterior teeth from the denture with incorrect occlusal plane, re-register, and then

    reset or remake the dentures.

    We talked about the anterior guidance last time and we said that the anterior guidance in the

    end is almost zero and theres no vertical overlap between anterior teeth, if this is the case then

    excessive force on the dentures will cause displacement. You could shorten the lower teeth to

    decrease this overlap between anterior teeth while reserving the aesthetics.

    4 Managing Problems & Immediate Dentures| Prosthodontics

    Last lower tooth is too posteriorly placed

    Teeth overlie crest of the residual ridge as it rises towards

    the retromolar pad. Pressure on these teeth causes denture

    to slip up.

    Recognizing: Apply finger pressure on the last tooth and

    observe if denture moves.

    Management: Remove most posterior teeth from dentures.

    Sometimes the last tooth is placed high up on the ascending ramus of the mandible. You should

    place the 6 on the most concave part of the mandible, and then you can see if theres space

    behind the 6 to place the 7. If the 7 is raised on the ascending ramus of the mandible, whenever

    the patient talks the denture will tip forward. If thats the case, you have to remove the most

    posterior part of the denture and stop up to the 6.

    Orientation of the occlusal plane is not parallel to the ridge

    Mastication produces forces that tend to move the dentures over

    supporting tissues. Problems can occur with large tuberosities, as these

    can depress the occlusal plane posteriorly and this may place the lower

    denture at a forward force.

    Management: Reset the teeth or remake the dentures.

    We need the occlusal orientation to be parallel to the ridges. If its not, this will cause thedentures to be unstable. It is very common in the clinics to be caused by large tuberosities. Here

    you are forced to make an occlusal orientation that is not parallel to the ridges. There will be

    contact in the posterior part and a big gap anteriorly, if there are large tuberosities posteriorly.

    You can manage that by either adjusting the wax posteriorly and lifting the occlusal orientation

    upwards, or lowering the lower rims, giving more free way space just to avoid the heavy contact

    posteriorly, and to provide space for teeth posteriorly. You could also shorten the upper teeth,

    or if its too excessive you could surgically adjust the tuberosity. If no surgery is indicated you

    could do the previous techniques without compromising the aesthetics.

    Support Problems

    Lack of Ridge

    Little resistance to forces in lateral and anterio-posterior directions; the

    denture is liable to move, and thus disrupts the retentive seal.

  • 8/13/2019 Prost Ho Don Tics 10

    5/15

    5 Managing Problems & Immediate Dentures| Prosthodontics

    Recognizing: By observation of the ridge. It may be associated with a shallow palate.

    Denture may move easily with finger pressure. It is very common with class five.

    Management: Minimize displacing forces and maximize retentive forces.

    Fibrous displaceable ridge

    Forces of mastication cause the denture to sink into and tilt on

    supporting tissues, thus disrupting retentive seal.

    Recognizing: By palpation of the residual ridge to determine

    displaceability. Denture may sink into tissues under finger pressure.

    History of presence of natural teeth (usually lower anteriors). Teeth

    may appear to meet evenly under forceful occlusion, but when the

    teeth just meet, incorrect occlusion often appears.

    Management: Reline/rebase.

    Precautions:

    - Remove acrylic from impression surface until no contact is evident. (You could check

    with disclosing material)

    - Add vent holes in the labial /buccal flange of the dentures.

    - Use a low viscosity material.

    - Provide best possible posterior teeth.

    The non-resilient soft tissue does not adapt to impression surface, may be associated with

    Endocrine/Nutritional deficiencies. Management is similar to fibrous displaceable ridge.

    You can recognize that problem by applying proper examination. If you missed it, you can use

    pressure indicating paste in order to see the area, adjust it, relief it and remake the denture. You

    have to use a technique we talked about in the impression lecture that will selectively provide a

    light body, so when the denture sets in place it doesnt apply pressure on that area.

    Bony prominence covered by thin mucosa

    The same technique could be used when theres a bony prominence covered

    by thin mucosa. You must selectively avoid excessive pressure on that area.

    (e.g., prominent maxillary midline suture, denture rocks about fulcrum

    produced by area of reduced tissue displaceability and thus disrupting the

    seal.)

    Recognizing: Denture rocks on finger pressure, inflammation of thin mucosa

    and palpation to determine degree of displaceabilityManagement: Remove acrylic from impression surface (indicated by disclosing agent).

    Precautions:

    - Beware of excessive creation of space beneath the denture.

    - Beware of over thinning of the denture base which causes possible fracture.

    - Provide optimal occlusal contacts.

    This is just a picture that shows how to avoid pain that is related to

    many different things. It is relieved by putting cotton inside the

    denture. Many reasons cause pain associated to dentures and you

    have to carefully identify them.

    Causes of Discomfort

    Discomfort could be related to the impression surface, polished or occlusal surface.

    Related to impression surface:

    - Pressure areas due to: Faulty impression, damage to the working cast or warping of the

    base during processing or immersing in too hot water

    - Denture base not relieved in a region of undercut

    - Pearls of acrylic or sharp ridges on the fitting surface of the denture

    - Lack of appropriate relief over tori, atrophic mucosa

    - Overextension of peripheries, unrelieved frenal /muscle attachment

    - Pressure on mylohyoid ridge

    - Atrophic mucosa, spiky ridge

    - Postdam too deep

    Related to polished surface: Maxillary denture constraining the coronoid process.

    Related to occlusal surface:

    - Slide form RCP to ICP- Lack of incisal overjet

    - Lack of appropriate freeway space

    - Lack of occlusal contacts or even contacts

    Related to other causes:

    - Instability of dentures

    - Burning mouth syndrome

    - Xerostomia

    - TMD

    Problems in Speech

    Noise on speaking.

    Recognizing: Excessive OVD, occlusal interferences, loose dentures

    Sibilants, e.g., S

    Recognizing: Ask the patient to count from 60-70 to see how the letter S is pronounced,

    anterior teeth should be just out of contact. If they arent you have to check the vertical

    dimension.

  • 8/13/2019 Prost Ho Don Tics 10

    7/15

    7 Managing Problems & Immediate Dentures| Prosthodontics

    Bilabial sounds, e.g., P B

    Recognizing: You have to see if lip approximation is easily attained. You must check the vertical

    dimension and the incisal position.

    Labio dental sounds, e.g., F V

    Recognizing: Does the vermilion border of the lower lip rest against the incisal edges of upper

    teeth? On swallowing, does the lower lip overlap the labial surface of the maxillary incisors? If

    not we must check the position of upper teeth and the vertical dimension.

    Regarding speech dont be meticulous in the registration stage because sometimes the shape of

    wax rim or the quantity of saliva could affect it. But generally when the patient is complaining

    from noise on speaking it could be excessive OVD dimension, occlusal interference or loose

    dentures.

    Psychological Problems

    Such as gag reflex. These are some of the techniques on how to handle such a case:

    - Fixatives

    - Training plates

    - Desensitizing programs: ask the patient to brush his palate with a soft brush, over time

    that will desensitize the area.

    - Hypnosis

    - Professional psychological counselor

    Other Problems

    Other problems such as burning mouth syndrome, denture stomatitis, angular chelitis, allergy

    and TMJ disorders. You think of those problems when you exclude the others.

    8 Managing Problems & Immediate Dentures| Prosthodontics

    Immediate Dentures

    What is an immediate denture? How does it differ from the conventional one?

    Some patients ask for immediate dentures especially in the private clinics, but in public

    hospitals you wont encounter such patients. An immediate denture is a partial or complete

    denture constructed for insertion immediately following the extraction of natural teeth. On the

    day of extraction your dentures should be ready. You send the patient to the surgery clinic, if

    you are not extracting the teeth yourself. He comes back to you and you insert the denture

    immediately. Today we will learn the concept of constructing an immediate denture, advantages

    and disadvantages, types of immediate dentures and how to fabricate them. It differs a little

    from the conventional dentures.

    You might get a patient who is very concerned about his

    appearance, but you dont see that these teeth provideany aesthetics for the patient, they are very poor. The

    patient says that he cant stay without teeth specially the

    anterior ones, so you have to provide him with an

    immediate replacement.

    When you check the radiograph, you will see that theres

    massive bone resorption and the teeth have poor

    prognosis and are all indicated for extraction.

    Treatment Options:

    - Extract all teeth and wait (6-8) weeks for the

    extraction sites to heal.

    - Convert an existing RPD into an interim immediate complete denture.

    - Fabricate a conventional immediate complete denture.

    You wont be doing an immediate denture in your training course but you should know the

    concept and technique. Its easier than the conventional denture, but its more difficult in the

    insertion visit. Thats why it costs more, because the patient will come for more relining and

    adjustment procedures, and there will be high resorption.

    Types of immediate dentures

    The immediate denture has two types: the interim immediate denture and the conventional or

    permanent immediate denture.

    Interim Immediate Complete Dentures (IICD)

    - The IICD is replaced with new dentures once healing is completed.

    - Usually all remaining teeth are extracted on the insertion visit.

  • 8/13/2019 Prost Ho Don Tics 10

    9/15

    9 Managing Problems & Immediate Dentures| Prosthodontics

    - If an existing RPD is present, the teeth to be replaced are added to the denture with the

    necessary base material.

    Interim means temporary. I extract all the patients anterior and posterior teeth on the same

    visit. And then I place the denture. There are many sites of healing sockets, so there will be

    resorption and many changes will occur anteriorly and posteriorly. You place the dentures

    immediately and you see the patient after 24 hours, a week and a month in order to doadjustments and relining, because theres a lot of resorption. After 6-8 weeks or a little more,

    youll see that there are a lot of changes, even aesthetically, because the ridge has changed, as

    well as the occlusal orientation and the incisal show. So its an interim denture that serves the

    patient in a transitional stage, until the sockets have healed completely. Then you replace it with

    a conventional complete denture.

    If the patient didnt extract all his teeth and he doesnt want a conventional denture, he could

    order a partial one. Every time he loses a tooth, we replace it, until the denture looks like a

    patchwork. And then you change it. So the interim RPD serves the patient for a short time and

    transits him from being partially dentate to being completely edentulous. That partial denture is

    like a training plate that helps him to get used to the complete denture. You take an impression

    with the denture in place, after that the technician will remove the natural teeth on the model

    and add acrylic ones instead, then he does flasking and packing, and thats it. He turned the

    partial denture into a complete denture and thats the technique. You treat the case as if its an

    RPD, so you must register the occlusion.

    Conventional Immediate CD

    If you dont want to give your patient two dentures; a spare one and a new one, and hes really

    concerned about the aesthetics, you could extract the posterior teeth only, leave the anterior

    ones and wait until the sockets heal. When the posterior part heals, it becomes a stable site for

    the dentures. There will only be changes in the anterior part, and that is what we might reline.

    No matter how much changes will occur, the occlusal orientation will not change, the denture is

    stable posteriorly. If I extract everything at the same time, there will be huge changes in the

    dimensions and the aesthetics of the dentures, and the patient will have to change it. But if the

    denture was stable, only the anterior part will change and thats where I reline. Thats what we

    call a permanent immediate denture.

    Advantages and Disadvantages

    Advantages of the immediate denture

    - The patient will have no time without teeth. Patients are therefore able to continue

    their social and business activities without embarrassment.

    - The general appearance is less affected.

  • 8/13/2019 Prost Ho Don Tics 10

    10/15

    10 Managing Problems & Immediate Dentures| Prosthodontics

    - Minimal changes in muscle tone and occlusal vertical dimension.

    - Centric relation is easier to record, because there are remaining natural teeth. You copy

    the vertical dimension and theres no need to mark dots or measure the freeway space.

    As if you are doing a partial denture. You take the VD and the RCP for the natural teeth.

    - Minimal changes in speech and chewing habits.

    Disadvantages of the immediate denture

    - As healing proceeds and resorption occurs, the denture will not fit. The immediate

    denture needs to be relined or remade in 6 months to a year following insertion. Even if

    you try to make it permanent, there will always be changes that require recalls and

    adjustments.

    - The treatment with immediate denture is more costly.

    - There is no Try-in; the aesthetics of complete denture cannot be evaluated until the

    insertion appointment, because you left the natural teeth until the insertion visit and

    removed them from the model. You can do an impression to make sure that the centric

    is there. Are there enough teeth to hold the cast? If not I will make wax rims, just likethe conventional one. I take a primary and a secondary impression, a registration if its

    needed, if not I go to the insertion stage. The technician removes them on the model

    and he replaces them with acrylic teeth as if he has extracted the teeth. He sets the

    teeth and he prepares it as a complete denture. Now that you have a complete denture

    you extract the teeth and put the denture. But here you are predicting. It is better if the

    dentist removes the teeth on the cast in order to predict how much healing will take

    place.

    - The anterior ridge is an undercut (often severe).

    Fabrication of immediate denture

    History and examination

    - A full medical and dental history should be obtained from all patients requiring

    dentures. Details of past illnesses, present medications, difficulties with extractions,

    experience of anesthetics, etc assume a special significance in a patient for whom

    immediate dentures are planned.

    - As a result of this examination, it is sometimes possible to divide the natural teeth into

    four classes:

    o

    Teeth that are not to be extracted in the foreseeable future. The teeth may needconservative or periodontal treatment or selected teeth may be considered for

    overdenture abutments or abutments for an RPD.

    o Teeth that are to be extracted but no denture is fitted in the extraction site for

    about 6 months. These teeth are usually posterior and not required for aesthetics or

    maintenance of the occlusal vertical dimension. The object is to provide a stable site

    for the immediate denture.

  • 8/13/2019 Prost Ho Don Tics 10

    11/15

    11 Managing Problems & Immediate Dentures| Prosthodontics

    o Teeth which are to be extracted and immediately replaced with a denture. These

    are usually anterior teeth.

    o Teeth with very limited prognosis which are worth retaining temporarily to aid the

    transition to denture wearing, because sometimes specially in the private clinics

    medico-legal issues arise. The patient has teeth with poor prognosis. You cant put a

    bridge or a partial denture and the patient refuses to extract them.

    Treatment planning

    From the findings of the history and examination, the treatment plan may be:

    - No denture to be provided.

    - The provision of temporary acrylic partial dentures to fill the posterior edentulous

    spaces. This may be a valuable training device if it is considered that the patient is likely

    to show poor adaptation to complete dentures.

    - The provision of immediate dentures that may take the form of:

    o Additions to partial dentures. These are termed transitional immediate dentures.

    o New dentures, complete or partial, to replace those teeth that are already missing andthose to be extracted.

    When immediate dentures are proposed, patients should be advised of the necessity for early

    relining and/or remaking with associated additional visits and extra costs.

    Design of Immediate Denture

    One of the students I supervise on had a case in which the patient has good fullness, even

    without him wearing the dentures, because the ridge hasnt resorbed, yet. When the patient

    wears the denture there will be too much fullness and the patient will not accept that. Thats

    the case for the immediate denture. The ridge will be prominent and there may be an undercut.We either do a Labial flange (complete or partial) or Open-faced (socketed). A final decision is

    usually deferred until study casts are available.

    Advantages of a labial flange:

    - Greater stability and increased retention forces

    - Improved strength

    - Tooth arrangement can be altered

    - No interference with sutures

    - Stable appearance

    - Easier relining if there are any fractures to hold.

    Disadvantages of a labial flange:

    - May produce unnatural fullness of the lip and the patient may not

    like the appearance.

    - Bony undercuts labial to the alveolar ridge may prevent the use of a

    flange unless they are surgically removed.

  • 8/13/2019 Prost Ho Don Tics 10

    12/15

    12 Managing Problems & Immediate Dentures| Prosthodontics

    The use of a partial flange overcomes the disadvantages of a full flange while retaining most of

    the advantages. It is therefore important to assess each case comprehensively before the trial

    insertion stage.

    Synopsis of Clinical and Laboratory Procedures

    Preliminary alginate impression for study casts

    - Request spaced perforated acrylic special trays.

    - Decontaminate.

    - The impression is poured with dental stone. A custom tray is

    fabricated with acrylic resin. The remaining teeth are covered

    with a double thickness of baseplate wax.

    Working Impressions

    - The custom tray is checked in the patients mouth as normal.

    - The posterior palatal seal can be determined and transferred to the cast.

    - The final impression is taken with a suitable impression material.

    - When the teeth are very mobile, care must be taken to avoid extracting the teeth with

    the impression.

    - The undercuts and interproximal areas can be blocked out with wax and petrolatum.

    - In severe cases, a vacuum formed resin stent can be utilized as a protective sheath while

    making the impression

    Recording the jaw relationship

    - If there is sufficient tooth contact to establish the required

    jaw relationship, an interocclusal record should be taken

    together with the shade and mould of the teeth.

    - If insufficient tooth contact, occlusal rims will be required.

    - Procedure undertaken as for partial dentures construction.

    - Take the shade and mould of the anterior teeth.

    - Indicate the occlusal configuration, size and material of the posterior teeth

    Decision as to whether open-faced or flange design

    - The depth of penetration of the labial portion of the cervical neck of the tooth is

    dependent upon the bone level around the teeth involved. This is determined by

    using a periodontal probe and radiographs. If a flange is to be provided, considerwhether the surgical removal of bony undercuts is necessary. I have soft tissue that

    will disappear, so I have to predict how much the gum will collapse and resorb,

    based on that, I extract the teeth. If theres too much probing depth, that means

    that most of the gum doesnt have bone (no undercuts), and then you can decide if

    youll do a full flange, partial flange or no flange.

    13/15

    13 Managing Problems & Immediate Dentures| Prosthodontics

    - If a partial flange is indicated, the labial surface of the alveolar ridge should be surveyed

    relative to the path of insertion and a line is drawn about 1mm beyond the survey line

    to indicate the extension of the flange.

    Instructions to the laboratory

    - Teeth for extraction should be indicated on the working casts.

    - If the immediate restoration is a partial denture, specify undercuts which must be

    blocked out.

    - Instructions to set up the artificial teeth in the edentulous spaces for trial insertion in

    the mouth.

    Trial Insertion

    - The teeth that are to be extracted and immediately replaced by the

    new denture are still in situ in the jaws. Thus the positioning and

    aesthetics of the replacement teeth cannot be checked in the

    mouth before the denture is processed.

    - The trial dentures are checked for jaw relationship.- The patient checks the appearance of any visible teeth.

    - If appropriate, the post dam should be cut in the upper cast to the

    correct position, length, depth and width before decontamination.

    - Arrangement are made for the tooth extractions and the fit of the

    immediate denture at the next patient appointment

    Preparations of the cast before processing

    - The dentist is responsible for removing the teeth from the cast andpreparing the cast to receive the artificial teeth. This will be

    dependent upon the bone levels and previous measurements.

    - You scrap the teeth off the model depending on your prediction.

    - The more accurate you are, the less relining youll do later.

    Instructions to the laboratory

    - A clear acrylic surgical template is constructed on a duplicate of the

    trimmed cast if an alveolectomy is to be performed.- Artificial teeth are fitted to the prepared working cast with any

    particular aesthetic requirement requested by the patient.

    - Indicate whether flange or open-faced design

    - The trial denture with the replacement teeth is processed.

    Fitting the denture

    - Great care must be taken to avoid trauma to the anaesthetized tissues.

    - When fitting immediate dentures there are 3 common types of adjustment:

    o Removal of acrylic pearls and spicules.

    o Open-faced teeth that enter the lingual area of the socket.

    o

    Flanges which enter too far into bony undercuts.- On insertion of the denture obvious occlusal discrepancies and overextension must be

    corrected. However, a definitive adjustment of the occlusion is not possible because of

    swelling.

    - Cold packs are suggested for the first several hours. The patient must not remove the

    denture in the first 48 hours. Tissue inflammation and edema may prevent the

    reinsertion of the denture. A soft diet is preferred. Appropriate pain control medications

    are prescribed as needed.

    Instructions to the patient

    - Dentures should not be removed for 24 hours, because there might be swelling. If we

    remove it and theres swelling it will not fit anymore. That will also help control the

    bleeding. Once you fit the denture in the insertion visit the patient should not remove it

    until you see him after 24 hours.

    - Post extraction instructions are given as normal. (antibiotics or medications if needed)

    - Review at 24 hours

    - Dentures are removed from the mouth and cleaned with a brush, soap and water.

    - The mouth is examined for indications of border overextension or other excessivepressure from the denture base and adjusted accordingly.

    - Obvious occlusal discrepancies are adjusted.

    - You can use tissue conditioner or soft reline.

    - Oral and denture hygiene is given together with a suitable patient handout.

    - Identifying marks can be applied to the dentures.

    - Review at 1 week

    - All factors mentioned above at the 24 hour review should be checked again with proper

    evaluation and adjustment of the occlusion.

    - Regular review appointments should be arranged - one month, three months, six

    months and then annually thereafter.

    - Remind the patient that temporary relining will be necessary at a review in the near

    future and that permanent relining or the construction of new dentures will be

    necessary at a later stage.
