In 1985, Benjamin Bloom, a professor of education at the University of Chicago,published a book, which examined the critical factors that contribute to developingexpertise and thus talent, Developing Talent in Young People. Although, many of us

are not that young anymore, Bloom’s concept is still very relevant as we face the currenteconomic downturn and look at different ways of improving ourselves in order to besuccessful within the current external economic situation we are facing.

One thing that is evident is that all superb performers Bloom investigated hadpracticed intensively, had studied with devoted teachers and had been supported by theirfamilies and communities. Success in any field is congruent with expertise. Consistently,evidence shows that experts are always made not born. They are made through focusededucation and commitment to the betterment of the individual to the service of others.

History has shown that education has a great impact on our professional lives in theway of achievements. Success in the dental technology field is no different. Those whohave taken advantage of studying to upgrade their knowledge and techniques reinforcethis reality.

For example, business studies indicate that all businesses including dental technologyare successful if they can market effectively and can provide a product or service that hasone (or ideally all 3) of the following characteristics. The product or service has to beperceived as Better, Cheaper and Faster (ie. delivery of the product or service) thansomething else.

Through positive thinking, proactive initiatives and implementing the pre-established educational plan success is closer than one may think. It is never too lateto begin the process. I hope that many of you embrace the educational opportunitiesthat our Congress provides to improve your professional status and create steps towardsyou becoming an expert in your chosen area.

Economic downturns are times for new ideas and practices to flourish. That might belittle cheer for now, but the current situation creates enormous opportunity for theevolving experts those individuals that embrace education and are prepared to pay theprice in time, effort and money in order to accept change and prosper.

Material Selection and Shade Matching for a Single Central IncisorLuke Kahng, CDT

IntroductionWith regard to esthetics, the single central incisor poses thegreatest restorative challenge for the clinician; not surprisingly,it can also be the most difficult tooth for the dental technicianto match. Selecting the shade of the restoration depends in parton the material used for the understructure, and there is a wideassortment available from which to choose. The following areamong the most common:

An experienced technician can mask the underlyingdark tooth color using porcelains with detailed color-masking techniques.

Understructure Material• Zirconia (e.g., Procera® [Nobel Biocare; Yorba Linda, CA],

Lava™ [3M ESPE, St. Paul, MN], Cercon® [Dentsply Int.,York, PA], Everest™ [KaVo America Corp.; Lake Zurich,IL], In-Ceram® [Vident; Brea, CA])• Flexural strength: approximately 1,200 Mpa • Translucency: very low• Opacity: high

• Alumina core or glass-infiltrated alumina (e.g., Procera, In-Ceram)• Flexural strength: 450 to 700 MPa• Translucency: low• Opacity: moderate

• Pressed Ceramics (leucite-reinforced or lithium-disilicateand apatite glass ceramics, e.g., Empress® [Ivoclar Vivadent;Amherst, NY], OPC® [Pentron; Wallingford, CT],Authentic® [Jensen Industries; North Haven, CT], GCInitial [GC America; Alsip, IL])• Flexural strength: 120 to 450 MPa• Translucency: high • Opacity: low

• Nonoxidizing metal (e.g., Captek™ [Captek; AltamonteSprings, FL], Bio 2000® [Argen; San Diego, CA],Sinterkor™ [Pentron]) • Similar to porcelain-fused-tometal (PFM)• Flexural strength: equal to porcelain to metal• Translucency: low—equal to porcelain to metal• Opacity: high—equal to porcelain to metal

Factors to ConsiderThe choice of material depends to a large extent onfactors unique to each patient. No single material is idealfor every case; each will have its advantages anddrawbacks. For example, the porcelain-to-oxidizing metalmaterials are susceptible to excessive opacity, which willresult in a lifeless-looking restoration and must beavoided. The feldspathic porcelain materials (veneers andjackets) of less than 0.8-mm thickness tend to give a

Smiles-Aug/Sep09.qxd:Smiles 7/23/09 8:59 AM

restoration excessive translucency, which will result in arestoration that looks too gray and dark.1 The followingare some of the factors to consider when selectingmaterials:

Color of the Tooth Preparation If, after preparation, the underlying tooth color has a darkshade (i.e., between A5 and C10), the core of the materialchosen should be opacious to mask the underlying dark color.However, an experienced technician can mask the underlyingdark tooth color using porcelains with detailed color-maskingtechniques.

It is the dental technician’s responsibility toremain educated about the latest materialsand techniques; the proper function of the occlusion; and the optimal muscle position

for esthetics, longevity, and comfort.

Design of the Preparation

Some metal-free restorations require strict preparationtechniques, such as a shoulder or a deep chamfer margin.Before selecting a material, the dental technician must considerwhether the tooth structure allows margins of 1.0 mm, whetherthe margins are subgingival or supragingival, and so forth.

Patient’s Medical HistoryThe choice of material can be limited by allergies, a history ofbruxism, etc.

Durability of the MaterialRegardless of how esthetic a restoration looks, it is not worththe cost to the patient or the efforts of the dentist and dentaltechnician if it lacks durability.

Each of these factors must be considered in every case toachieve the best esthetic results. Metal-free restorations are

more similar to a natural tooth than to an artificial crown.While metal-free restorations are unlikely to replace PFMrestorations, they offer alternatives for patients who demand amore natural looking restoration. It is the dental technician’sresponsibility to remain educated about the latest materials andtechniques; the proper function of the occlusion; and theoptimal muscle position for esthetics, longevity, and comfort.

New materials are constantly being introduced bymanufacturers. However, it is unwise to use materials until theyhave been used and tested for a number of years. Before using anew material for the first time, the dental technician must askseveral questions, such as: How long has the material beenavailable? What studies have been conducted on the material?

In addition to the material used for the understructure, thelayering porcelain must be selected with equal care. A porcelainsystem with internal colors will achieve maximum esthetics.Today’s specialized porcelains give the dental technician anadvantage.

Case ReportA female patient disliked the existing crown on a maxillarycentral incisor, which had been cemented only three yearspreviously. She reported that she avoided smiling because of thecrown’s unpleasant appearance. The dentist who had placed thecrown also had done a composite build-up on the mesial andincisal third of the lateral incisor.

When the crown was removed, it was determined that nomodification of the preparation was needed (Fig. 1).Impressions were taken, and the tooth was temporized (Fig. 2).Together, the dentist and the dental technician conducted acustom shade mapping; afterward, the dental technician did afull color mapping (Fig. 3) with the porcelain colors that areavailable.

Shade Mapping and PhotographyComprehensive shade mapping is a time-consuming process.No single base shade can provide an adequate esthetic match.Different shades are needed in the gingival, body, and incisal

thirds of the tooth, which also must be divided according to itsmesial and distal characterizations. Standard shade tabs canserve as a base shade and offer a place to start; however, becauseof the popularity of bleaching, establishing a base shade in itselfcan be difficult. Moreover, because the thickness of the shadetabs does not match that of the finished restoration, some colordifferences must be anticipated when using these, as well.

Unfortunately, shade guides are not representative of thevalue of real teeth, which is another reason why relying onshade tab assessment alone can be problematic.

Special shade tabs are also needed for the opalescence,fluorescence, and translucency of natural teeth. To achieve theseeffects, the dental technician must make use of a porcelainsystem with its own effect powders and color-matching tabs andnomenclature.

This can also be used to match the surface characteristicssuch as glaze, texture, and luster.

If light should reflect off the crown in a different mannerfrom the neighboring teeth, it will betray the fact that it is anartificial restoration even if the shade is perfect.

If the dental technician cannot meet the patient in person,

photography must be used to supplement and enhancecommunication with the dentist. Reference photography withshade tabs is a highly effective means of communication. Digitalphotographs show excellent detail with regard to colors, glaze,texture, and luster.

Master casts were fabricated. In addition to themaster casts, the following information was provided:

• The preparation revealed slight discoloration at the incisalaspect.

• The preparation design offered sufficient room for therestoration.

• The patient had no known allergies, and her occlusion wasnot a concern.

• The patient was looking for a permanent type of restoration.3

Based on all of these factors, pressed ceramics with layeringporcelain was the material selected for the restoration in this case.

Pressed Ceramics with Layering PorcelainFor the pressed ceramics, a variety of different manufacturers’ingots were selected for a wide assortment of colors, includingdentin, bleached (A0, A00, B0, B00 with 75% opacity), andveneer shades; occlusal enamel light and milky; translucentingots; and opaque ingots. The opaque ingots (with 85%opacity) are valuable for masking discolored preparations. Withpressed ceramics, too much translucency can occur, so a variety

of choices are needed. The opacity level of the ingots rangesfrom about 30% to 85%.

Once the choice of material was made, the central incisorwas waxed to full contour on the cast and cut back for theporcelain layering. The wax-up was then sprued, invested, andprepared to press. After the ceramic has been pressed, care mustbe taken to avoid overheating it when cutting off the sprues ormodifying the framework. When the cutback framework was

ready for porcelain application, the thickness was evaluated todetermine the amount of room available for layering porcelain.If necessary, the shade of the framework can be modified withinternal stains (Fig. 4), which can be applied either on thepressed ceramic coping material or internally on the porcelainbuild-up, as well as externally. The thickness of the porcelainsystem color-matching tabs also can be a problem. Samplecolors of the translucent neutral, enamel opal, enamel occlusal,cervical translucent, and clear fluorescence were fabricated inthicknesses of 0.3 to 0.4 mm (Figs. 5 & 6), then ground andglazed to represent a final restoration.

The thickness of these fired porcelain discs is important;discs 0.2 mm or less will be too clear, while those at 0.6 mm willbe too thick. The translucent colors should be placed on top ofeach other to assess light transmission colors (Fig. 7). Thesesamples allow the dental technician to mimic the shadow zones,or areas of the restoration (Fig. 8) that will lose both chromaand brilliance.

Inside powders and a specially developed, highly fluorescentprimary dentin, which gives the color depth effect, were usedfor the first layer of porcelain (Fig. 9). Dentin porcelain wasapplied over the gingival and middle thirds to give the crownoptimal chroma (i.e., saturation or strength of hue). The coloris produced by reflection from the dentin. The dentin porcelain

was cut back to provide room for a mamelon effect. Enamel andenamel opal porcelain were applied to provide shade graduationsimilar to that of natural incisal areas as well as translucency.The enamel powder has a high level of opalescence inconjunction with high translucency to create an underlyingbackground to the mammelon effect (Fig. 10).4

A thin layer of clear fluorescence powder was appliedbetween the dentin and enamels. This so-called sclerose dentinbrings true-to-nature depth into the tooth color. Translucentmodifiers were applied over the clear fluorescence powder; theycan be used individually or mixed with the neutral or opaltranslucent.

Enamel effect powders were used at the incisal area to givethe natural appearance that cannot be achieved with just oneenamel shade and an application of translucent, the neutralcolor (Fig. 11). Then the enamel powder was applied to achievefull color saturation. Dentin enamel incisal and occlusal build-up was applied to the lingual of the crown. To complete thebuild-up at the contact areas, the crown was removed from thecast. Then it was ready for baking and firing.

Surface TextureMatching the surface texture is just as important as matchingthe shade (Fig. 12). Indeed, surface texture is one of the most

DLANY Smiles 11

important elements of an esthetic restoration. The surfacetexture of an anterior tooth is on prominent display (Fig. 13).For this reason, it will appear heavier than the neighboringteeth. If light should reflect off the crown in a different mannerfrom the neighboring teeth, it will betray the fact that it is anartificial restoration even if the shade is perfect.

Surface texture can affect brightness, color saturation, luster,and so forth (Fig. 14). A natural tooth does not present anabsolutely smooth surface; it is generally a gently undulating

surface, traversed by very fine horizontal grooves. Thehorizontal parallel ridges, or growth lines, and the small verticalridges that run parallel to the marginal ridges help it to blendinto the oral environment. Porcelain color build-up reveals atechnician’s technical ability, but the surface texture reveals atechnician’s esthetic touch (Fig. 15).5,6

The completed crown was placed on the prepared tooth(Figs 16 & 17). The patient was very pleased with the resultsand no longer found it necessary to hide her smile (Fig 18).

Conclusion

In terms of shade matching, the single central incisor can be themost difficult tooth for a dental technician to fabricate. Theselection of the material for the framework is only the first stepin this process. Several factors must be considered, includingthe design of the restoration, the patient’s medical history, andthe durability of the material. Once the correct material isselected, the communication between dentist and dentaltechnician and the dental technician’s knowledge and talent areof paramount importance in achieving a natural-lookingrestoration and a successful esthetic result.

Going PinlessJames Garland, CDT

Dental labs today face constant changes in technologyand increasing overseas competition. CAD/CAMtechnology aims to reduce direct labor cost yet foreign

labor remains cheaper. Finding and implementing practicaltools of efficiency, accuracy and simplicity into our laboratoriesto stay competitive and cost effective can be especially trickywhen investing in new technology or change.

When it comes to the model and die process, “cost effective”is the whole point of Monotrac, offering more versatility,options, accuracy and efficiency than any other model, die andarticulation system, period. The integrated articulator with

pinless model tray allows a single pour cast in place setup that issimple fast and complete. Unlike other pinless model trays, diesare easily removed from the base, easy to relocate and arecompletely stable throughout the arch. Even the thinnest ofdies can be solid model sectioned on this model base. Monotracis also the only pinless system having full range capabilities andnot limited to a few selected type cases. It ranges from the fullround house, to the single unit double bite trays, to therefractory and sectioned implant models, Monotrac does it all,with or without the usually rather cumbersome metalarticulators.

Monotrac is the only pinless disposable full range capable model, die and articulation system.


DLANY Smiles 17

The Monotrac set up will cut labor time by more than 70%,eliminating grinding, pinning, gluing, basing and articulationprocedures. How does Monotrac lose the pins? Dies areretained and supported by a patented internal retention baseconsisting of strategically spaced and sized tapered cones thatsupport the thinnest of die sections including multiple adjacentlower anteriors. Double bite impressions are cast directly ontothe articulator simultaneously within the pour up itself. Amissed bite in the impression can be easily corrected by simplyheating and softening the articulator arm and repositioning thecast bite.

The job of the articulator is to pinpoint solid centric,complete full equilibration and when needed, simulate cuspidrise. Monotrac is the only plastic disposable articulator on themarket capable of these requirements. The articulator arm willflex 360 degrees in the occlusal plane to effectively simulatenatural jaw movements following the natural wear facets and

guidance of the adjacent teeth - excursive movements includingprotrusive, retrusive, lateral and centric circle replication.Finally, Monotrac eliminates basing stone overexpansion. Thedistortion of basing stone, both in linear and cross archexpansion is eliminated. This increases accuracy the same wayas the Kiefer, Zeiser and Amanngirbach Girroform systems, butadditionally it is easier to use and more cost and time effective.

Monotrac offers four shapes of trays that utilize the sameuniversal snap on excursive flex articulator. These are StraightQuad, Radius Quad, Anterior, and the Full Arch.

This article features the full arch set up demonstrating amaxillary full arch round house case without any naturalocclusal stop support. The set up will require three MonotracPlug-in stops to create solid tripod vertical centric location andsupport. The case presents a separate pre-poured opposingmodel and bite registrations.

The base is inverted and aligned over the impression. The impression is removed and the Tear-away wall is peeled away. This allows themodel to be ejected from the tray and leaves a neat appearance and minimal finishwork.

Shown are the Monotrac V2 full arch tray and full arch round house impression.A red map pin is placed at the midline to guide the forward and centeredplacement position of the tray relation to the impression. A Sharpie can also beused to make guide markings.

The V2 tray and impression are poured with die stone.

The blue table top can be flipped up to use the diamond disk lathe stylefor making buccal and lingual cuts or can be top cut with a hand saw tocomplete the die section.

The method of die section is optional to the technician. It is completedby hand saw, hand piece disk or the Monotrac die cutter shown here.The Die –Cutter requires a warm model for fast, easy removal of fine dustdebris. Bottom cuts are made first for the bulk of the cut. Hand saw ordisk cuts are then made from the top in the margin area to meet thebottom cut. Dust and debris are immediately air blasted for completeremoval. Note it is also optional to create small snap breaks between diesfor a solid model effect.

Where required, a vertical stop is needed in unsupported or free endlocations. Monotrac patented Plug-in adjustable vertical stops aresimply pressed into the stop pockets in the tray.

The palatal area of the tray is tapped forward and back in a manner tocreate an even ejection of the model from the tray.

The opposing model is strapped down firmly into the trimmed biteregistrations with rubber bands maintaining positive pressure into the biteregistrations. Note that stone models expand beyond the impression ofthe bite registration restricting full passive seat into the bite registrations.The rubber bands force a more accurate full seat into the bite registrations.

Shown are all the components required to finish this set up. From top leftto right: flex arm hinge, trimmed bite registrations.

The IMPLA 3D Navigation System from SCHUTZDental Group, Inc is a tool for the production of high-class drilling templates with depth stop. The

templates can be created using virtually any implant system onthe market and can be produced in your own laboratory.

The complete system consists of the IMPLA 3D planningsoftware, laptop, IPS (Implant Positioning System) andconsumables. The software can also be purchased individually.

Accurate 3D planning requires the production of an X-Ray template, CT or Cone Beam X-Ray with this templatecorrectly in place, and a surgical guide produced from theinformation provided by the CT Scan and the planning done inthe 3D software. Steps 1-4 discuss the creation of an X-Raytemplate.

The IMPLA 3D Navigation System

Fig. 1: From the dentist’s impression a model is made in the traditionalmanner. A type 4 plaster should be used and the model should betrimmed with the base parallel to the occlusion area and the distal at 90degrees. As this is a model based system, it is very important to followthese parameters. If you wish to check the accuracy of your surgicalguide, you can pour a second model at this time.

Fig. 2: Mount the models in an articulator and wax-up or place acrylicteeth on the section where you wish to place the implants. Duplicate theteeth with a silicone form. Inject TemRay™ into the form. TemRay™ isa premixed radioopaque material that easily shows up on CT scans andgreatly reduces “scatter”.


DLANY Smiles 25

Fig.4: To complete the x-ray template, apply a straight plate at the incisal area to help the x-raydepartment into positioning the patient correctlyinto the CT or Cone Beam Scanner. It isimportant to make sure that the x-ray shows thereference holes perpendicular to occlusion.

Fig. 6: After all implants are placed and the planning is finished, acomplete forensic documentation of all implants can be printed. Forfully edentulous cases, “anchors” can easily be planned as well.There will be one page for each implant or anchor, showing allrelevant information including the five axis of where to adjust theIPS for the new location of the implant.

Fig. 5: The CD-Rom with the raw DICOM files are then uploaded intothe IMPLA 3D software. There is no data conversion needed. Thesoftware does this automatically for DICOM files and 60 other dataformats. After the file is imported, you can select your panoramic cut,and highlight the mandibular nerve canals. The software allows you tolook at your information in 5 different views, measure any distance youneed, check bone density and hardness and virtually place your implants.

Fig. 7: The model is placed on the IPS in the “zero” position at the firstindicated implant reference mark. Using the information from theprintout, the implant slice and panoramic displacement are adjusted andthen the new position of the implant is marked using articulating paper.The new angulation is now applied using the yellow and red gonimetervalues from the printout.

Fig. 8: Now that the new position and angulation of the implant areknown, you can now use the IPS to drill directly into the model. If youare using implants that have a sleeve with depth stop, you can now placean analog or drilling sleeve into the horizontal micrometer screw andthen place into the IPS and fix to the desired zero position. The gumdepth from the printout is now set by turning in .3 steps. Repeat steps 7and 8 for each implant.

Fig. 3: Isolate model and block out undercuts.Produce a template using FuturaGen™ (or

any other clear acrylic material) withimpressions of the opposite model. Place the

model on the IPS table and turn all three axesto 0 degrees. Use the drill on the IPS to create

reference holes in the position where youwould like to have the abutments. NOTE:

This is not the final position of the implants,only a reference marker for the software to

calculate the displacement and angulation ofthe implants that are planned in the software.

Take care to drill through the TemRay™material but not into the model.


26 DLANY Smiles

Fig. 9: The surgical guide is now created by injecting SteriGuide™around the drilling sleeves. This material is a high density compositewhich can be autoclaved with all drilling burs and implants.

Fig. 10: The finished guide is used to quickly, easily, and safely place theimplants necessary. This flapless procedure, combined with the autoclavalesurgical guide provides for less traumatic and stress free surgery for thedentist and patient.

Nobel Biocare – TiUnite

Nobel Biocare celebratesthe tenth anniversary ofthe development andtesting of its proprietarytitanium oxide dental

implant surface, TiUnite. In vivo testinghas proven that the moderately roughTiUnite surface enhances the speed atwhich implants osseointegrate, bystimulating rapid bone growth. Thisstimulated bone growth translates into asignificantly reduced drop in initial stabilityand during the critical period during whichstability changes from the purelymechanical to the biological interaction ofthe implant in living bone. Thismaintained stability is particularlyimportant in indications of soft orcompromised bone and in situations whenimplants are placed in immediate function(Glauser et al. 2001).
