What is a dental implant?
The prosthesis: it is either single crown, fixed partial denture, over denture
or any type of restoration connected to the implant and the abutment.
The abutment: it is the core area which is connected to the implant where
the prosthetic part is attached to it.
The implant (fixture): it is the actual part that is inserted into the bone.
1- Root form endosteal implants.

AN IMPLANT IS NOT A TOOTH:
Major differences:
Implant do not decay
Implant have no dental pulps
Implant have no periodontal membrane
Implant need to osseointegrate with bone

Root forms also categorized as
• One-stage implant:
Be placed in the bone and to immediately project through mucosa into theoral cavity (and to place the cover screw or healing collar).
• The two stage:
Implant requires two surgical procedures. First it is placed in bone to thelevel of the cortical plate and the oral mucosa is sutured over it. Then leftfor a prescribed healing period (usually 3 month in the mand. and 6 to 9months in the max.) depending on the quality of bone.
In a 2nd surgery the mucosa is reflected from the superior surface of imp.and healing collar is placed and project into the oral cavity is fastened tothe implant.

• In 1973 Flander a new design of endosseous implants to decrease the high
rate of failure of the old screw implants.
• The endosteal implant shaped in the approximate shape of the tooth root.
• It may be used for fixed, removable or fixed detachable prosthesis.
• It requires more than 10 mm vertical bone height, more than 6mm
buccolingual thickness, and more then 8mm mesiodistal width to avoid
undesirable complications.

It is a wedge shaped implant composed of head, neck
and body with vents which develops fibro osseous
integration with bone.
The blade implant is a mean of utilizing the narrow
and/ or shallow areas of remaining alveolar bone
where dimensions do not permit the use of root form
implants. The blade implant was restorable within a
month of placement by the superstructure

In 1952,,
while conducting research into the healing patterns of bone tissue,
accidentally discovered that when pure titanium comes into direct
contact with the living bone tissue, the two literally grow together to
form a permanent biological adhesion. He named this
phenomenon “ Osseointegration"

Osseointegration
A direct structural and
functional connection between
living bone and the surface of
implant
![Page 61: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/61.jpg)
Osseointegration (biologic processes)
• Blood clot formation, plasma proteins are attractedto the site accompanied by the release of cytokines andgrowth factors.
• Angiogenesis.
• Osteoprogenitor cells migration to the implantsurface.
• Cell differentiation.
• Deposition of bone at the implant surface and theosteotomy site.

Advantages of 2nd and 3rd Generations
• Increased surface area and better bone interlocking with implant surface.
• Enhanced wettability and adsorption of plasma proteins.
• Better retention of fibrin clot.
• Enhanced cell adhesion.
• Accelerated cell differentiation.
• Expression of Genes related to the calcification process is upregulated and accelerated (osteopontin,osteocalcin).

Conventional vs immediate loading
![Page 81: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/81.jpg)
A. Conventional Loading
• Branemark proposed aConventional loading following histheory of Osseointegration . He saidthat ; this is the most acceptedloading protocol that has been usedall over the world and is consideredthe safest and most convenientmethod due to its high successrates.
![Page 82: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/82.jpg)
Effect of Micro-motion on Implants during healing phase
• Micro-movement disturbs the tissue and vascular structures necessary for initial bone healing.
• Immediately after the insertion of an implant, the bone contact area is about 10-15% even in favourable bone sites such as anterior mandible.
• If the implant is subjected to load at this point, themesenchymal stem cells differentiate to fibroblasts and a fibrous connective tissue encapsulation results.
![Page 83: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/83.jpg)
B. Immediate and Early loading
• The rise of the 2nd and 3rd
generation of titanium implants,have lead to a dramaticimprovement in the process ofossoeintegration and bonehealing.
![Page 84: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/84.jpg)
IS it possible?
![Page 85: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/85.jpg)
• Several animal and human studies indicate that under the rightconditions, EARLIER LOADING OF OSSEOINTEGRATEDIMPLANTS IS POSSIBLE.
![Page 86: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/86.jpg)
• Implants surface improvements are not enough to ensurepredictability of immediate loading.
• Immediate loading still depends on other several factors toensure it’s success
![Page 87: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/87.jpg)
Factors affecting immediate loading ?
![Page 88: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/88.jpg)
1. Primary Stability • The key of successful loading is the effectiveness of the primary implant
stability.
• It prevents the micro-movements of the implant during theinitial healing phase.
![Page 89: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/89.jpg)
- Primary stability depends on two main factors
• Amount of initial bone contact
• Lateral compression of the osteotomy site
(hoop stresses)
![Page 90: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/90.jpg)
To reach these factors, certain rules should be followed:-
![Page 91: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/91.jpg)
Favourable bone density
minimum bone height 12mm
![Page 92: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/92.jpg)
Bicortical stabilization Tapered implants Insertion torque up-to 45 N
![Page 93: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/93.jpg)
2- Occlusion • Most of the damage is done by para-function.
• Clinical remounts are essential.
Anterior Single Tooth Out Of Occlusion
Posterior Quadrant Cases Anterior Guidance
One Edentulous Arch Or More Bilateral balance
![Page 94: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/94.jpg)
3. Systemic Health • systemic diseases
• Patients receiving medications
• Smokers and grinders are not indicated too.
![Page 95: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/95.jpg)
4. Patient Compliance • The implant is mostly vulnerable during the first 3 weeks of healing.
• Strict post operative instructions should be given to the patient.
• Placing the prosthesis out of occlusion is not enough, since the foodbolus can cause stresses on the implants.
• Tough foods should be avoided completely.
• Smoking is not allowed too.
• Para-functional habits are contra-indicated.
• Strict oral hygiene measures should be followed.
• Prophylactic Anti-biotic medication.
![Page 96: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/96.jpg)
5. Cost and Success Rate • Immediate loading is relatively more expensive, since it requires
more skills and preparations.
• The clinician and the patient must be willing to accept 5-20% lower success rate.
![Page 97: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/97.jpg)
6. Additional Implants • Additional implants are usually placed in immediate
implantation cases.
• This is to overcome the lower success rates and to help decrease forces falling per implant.
• This implant act as a backup plan
• Usually used for long span or edentulous cases
![Page 98: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/98.jpg)

7. Cantilevers And Frameworks • Cantilevers should be Contraindicated .
• Rigid frameworks are recommended since they help in implant splinting and distribution of forces
![Page 100: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/100.jpg)
8. Single Tooth Defects • Immediate loading in incisors region is predictable in
experienced hands, but has to be out of occlusion
• Cuspid region is avoided since it is difficult to control lateralforces in this area.
![Page 101: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/101.jpg)
9. Posterior Quadrants
• Non Linear configurationsis recommended.
• Anterior guidance isrecommended.
![Page 102: Introduction to Dental implant · What is a dental implant? The prosthesis: it is either single crown, fixed partial denture, over denture or any type of restoration connected to](https://reader036.fdocuments.in/reader036/viewer/2022062603/5f2b644ccdbb83785f58bad5/html5/thumbnails/102.jpg)
10. Mandibular Overdentures • Current studies support the use of micro-rough implants (minimum
diameter 3mm) in immediate loading in the mandible.
• Not enough evidence support this in the maxilla.
• Splinting of implants had an effect in one year survival rate.
![Page 103: Introduction to Dental implant · What is a dental implant?

Advantages Of Immediate Loading
• Provides convenience and emotional benefit to the patient,by improving aesthetics and decrease number of visits.
• Eliminates the need of a removable provisional restoration.
• Improves soft tissue adaptation
• Eliminates fixture exposure due to placing a removableprosthesis over it.
![Page 104: Introduction to Dental implant · What is a dental implant?

Disadvantages Of Immediate Loading
• Cannot be applied to every implant patient.
• Requires more chair side time during the surgical visit dueto loading preparation.
• Higher failure risk than conventional loading since too manyfactors to adjust to.
• Requires a high degree of skill, not recommended forbeginners.

• How safe are dental implants?Assumptions:
Analyses were linear, static and assumed that materials were
elastic, isotropic and homogenous.
100% osseointegration is assumed between bone and implant.
Bone and implant are assumed to be perfectly bonded.
The stresses in the bone due to the interference fit between
implant and abutment is assumed to be relaxed after the
insertion of the abutment.
