Restoring a single maxillary incisor presents the greatest blend challenge with dentistry in the smile zone. When the adjacent teeth are in good shape, I stay conservative. With chairside CAD/CAM using the Dentsply Sirona system, the Copy and Mirror is my preferred design approach creating a "DNA form and shape" by copying the adjacent central. The next step is choosing the ceramic that blends best for the case. Since the ceramic and cement refractory behavior will change once cemented, so will the value and blend. In my blend theater, I prefer placing a transitional restoration that is machined with the projected ceramic and luting

Even with the multi zirconia options of Katana and ZirCAD Multi, in my hands, infiltration is the simplest and most efficient way to enrich the cervical zone color and modify cervical saturation needs. And with just one firing...sintering. This video will share material recommendations and methods.
The method works on all zirconia brands.
- ZirCAD LT Colouring liquids (very forgiving)
- Katana STML
- ZirCAD Multi

Number one objective for anterior tooth upgrade treatment is addressing biofunctional demands. Biofunctional demands are often the challenge that is hard to navigate when there is advanced aging wear and tear conditions. This #cereccasereview will walk through the setup, CEREC design approach, and finished case addressing the maxillary central incisors when there is a challenging lingual wear issue.

Is it possible to design and create "pressable like" veneers with CEREC? The answer is YES. I do this all the time with razor blade margins and no chipping. This video with reviewing via case review the criteria for no prep or minimally prepared veneer applications, design tips, milling approach, and finishing protocols for thin e.max veneers and no marginal chipping.

Calibrating parameters is my focused avenue for mastering restorative fit and relieving clinical fit issues. The CEREC system is a restorative masterful system and parameters are at the center. This video will review the logic behind parameters so you will be able to understand when a parameter tweaking is needed.

CEREC Case Review for auto margin calculation in the CEREC 4.6 Software, it draws the margin for you! When the margins are "high and dry", auto margin drawing is spot on. This case review will highlight the CEREC software for creating an e.max onlay restoration.
