    • Step-by-Step Approaches for Anterior Direct Restorative ChallengesMastering Composite Artistry toCreate Anterior MasterpiecesNewton Fahl, Jr., DDS
    • This slide show presents a conservative, effective, and artisticphilosophy for performing esthetic direct anterior composite restorationsbased on the principles of emulating the proper form, color, and function of natural dentition. This particular article outlines step-by-step procedural approaches to solving day-to-day anterior direct restorative challenges, including tooth preparation, artistic application, and how to create seamless transitions from tooth substance to the syntheticcomposite restoratives using correct finishing and polishing techniques. Adapted from the full article, which originally appeared in the AACD’s Journal of Cosmetic Dentistry, Winter 2011 issue.

    • Color mock-ups were created for each tooth according to the achromatic and chromatic enamel techniques to verify the accuracy of the layering techniques.A properly trimmed siliconematrix made on a waxed-upmodel is key forestablishing a three-dimensional blueprint forlayering compositeincrements.
    • The lingual shelf must be anachromatic enamel no thicker than0.3 mm.Once cured, the lingual shelves ofboth centrals denote amber-whitishnuances that replicate theopalescence present in naturalenamel.
    • A fine-tipped dental instrument was used to gently create the dentin mamelons.
    • If correctly selected andapplied, artificial dentins of differentbrands should provide nature-mimicking color and opacity. Translucent effect enamels were used on both teeth to create natural opalescence and deep translucency around and in between the mamelons.
    • A Vita-based chromatic enamel was applied beyond the bevel line and contoured to create a seamless transition between the tooth structure and composite.
    • The chromatic enamel was faded-out An achromatic enamel was placedtoward the incisal third and cut back over the lobes to promote higheralong the incisal and proximal areas opacity and color value. to allow room for value effect enamels.
    • After refinement and curing, the To render the proximal lobes, a higher value achromatic enamel microfill shade of the same optical blended in, replicating optical characteristics as those of theproperties of natural enamel lobes. hybrid composite used on #8 was placed on #9.
    • A non-VITA, more translucent achromatic hybrid composite enamel was chosenfor the middle lobes of both central incisors to allow more dentin show-through. After application and light-curing of chromatic and achromatic enamels, both centrals depict similar optical characteristics. [Right] To establish natural facialplanes, the transitional line angles were evaluated and the facial planes worked with finishing discs to establish the primary anatomy.
    • The transitional line angles were worked and the embrasures opened until symmetry was achieved.Anatomy mapping was penciled inon the centrals to aid in attainingproper tooth morphology duringfinishing.

    • [Left] Worn blunt rubber rotaries were used to eliminate undesired texture and toimpart a smoother appearance. [Right] Specialized chamois and cotton wheelswere used in the polishing steps to produce an enamel-like gloss. Felt disc and aluminum oxide paste finalized the polishing, bringing the restorations to a smooth and glossy surface.
    • The finished restorations presented identical color and optical characteristics and were indistinguishable from the surrounding dentition.
    • The optical properties of the dentin and enamel composites selected for the buildups replicate the lifelike qualities of natural tooth structures.
