Frequencies of Failure In The Case of Ceramic Veneer Treatment and the Presence Of Composite Fillings: About A Clinical Trial

Abstract

Introduction: The restoration of teeth with composite ceramic veneers has always been a subject of controversy: for some authors the presence of such restorations is a source of failure while for others not necessarily. Material and Method: Our study; is a randomized clinical trial comparing three types of crown preparations for bonded ceramic veneers. Our clinical trial which evaluated 264 bonded veneers in 73 patients included 235 living teeth and 29 mortified teeth that underwent endodontic treatment. Among the secondary objectives of this study: the evaluation of the durability of ceramic veneers bonded to teeth with composite restorations. Results: The Chi-square test of the occurrence of events according to the unblocked / blocked character gives a p = 0.05 (p ≤ 0.05) so the difference is significant. Conclusion: The presence of composite fillings affected the survival rate of veneers in our study
