Course Objectives (1 CE Credit)
In modern dentistry, patients and doctors alike desire the utmost esthetics and strength from their restorations. With the advent of monolithic zirconia materials, which provide unbeatable strength with a natural appearance, neither doctor nor patient must make sacrifices to achieve these results during treatment. In anterior cases, certain procedures are necessitated in order to accomplish desired, natural-looking esthetics — especially in non-symmetrical cases. Because the choice of material affects many aspects of treatment, it is in the interest of clinicians to understand the parameters of all materials available so they can offer the most fitting solution for each patient’s unique circumstances. Topics of this lesson include:
- Selection criteria and indications of monolithic zirconia
- Gaining and preserving gingival harmony of central restorations
- Criteria for choosing the proper impression tray
- Evaluating gingival tissue thickness
- Removing preexisting crowns without damaging the gingiva
- Proper shade choice for a restoration to ensure esthetics
- Checking occlusion and esthetics of the final restoration
Monolithic zirconia is a material that can approach natural translucency, unlike many metal-based restorations. In addition, monolithic zirconia milled using CAD/CAM technology can offer superior marginal fit. Cementation can be done using the same process as a metal-based restoration, yet due to the nature of the material, dental professionals can avoid the risk of metal appearing at the margins or through the gingiva as the restoration ages with the patient.
CAUTION: When viewing the techniques, procedures, theories and materials presented, you must make your own decisions about specific treatment for patients and exercise personal professional judgment regarding the need for further clinical testing or education and your own clinical expertise before trying to implement new procedures.
