Abstract:

Ceramics are being used increasingly for both structural and esthetic components of prostheses and implants. The increasingly varied all-cermic systems will be reviewed in simplified but rational systematic fashion. Study of failed clinical specimens as well as examination of specimens from clinically-valid fatigue testing is yielding valuable information about what clinicians and manufacturers can do to best optimize both esthetics and function. Such study also leads to some concerns such as manufacturers who do not appear to have used basic ceramic engineering principles when transitioning a metal part to ceramic and extreme performance differences between manufacturers for seemingly identical parts. From the analysis of clinical failure, basic engineering principles have been worked-out to learn how clinicians and laboratories can optimize both durability and esthetics. This leads to some very practical recommendations that are easily incorporated into practice with all-ceramic systems. Zirconia ia increasingly of interest, both full-thickness and veneered. We have now solved the problem of porcelain chipping and are coming to better understand how to minimize/prevent wear of opposing teeth with full-thickness zirconia. With proper preparation and cementation ceramic systems for anterior teeth can now be selected from nearly any system; based upon many years of clinical trial data.
