Fulltext PDFIntroduction: The purpose of this investigation is to evaluate the influence of the design of the preparation on the longevity of porcelain veneers that are today widely used in the treatment of unsightly anterior teeth. To do this, we’ve compared three different designs: - The Type I: Window preparation leaving an intact incisal edge; - The Type II: Incisal edge overlap preparation; - The Type III: Palatal overlap preparation «full veneers». In order to provide a reliable treatment for saving the future of the tooth. Materials and Methods: Our study is a randomized clinical trial; on the comparison of 264 veneers stuck on 73 patients. The patient’s recruitment was done according to well-defined inclusion criteria. The information was reported on a clinical record. The study lasted 64 months with regular checks of 6 months, 12 months, 18 months, 24 months, 36 months, 48 months and 60 months. Results: In this study, the maxillary teeth prepared according to the three methods have shown that ceramic veneers have stable esthetic qualities; they are biologically acceptable in so far as the recommendations of current preparations are respected. The Chi square test revealed that there is statistically no significant difference between the three methods. Conclusion: The Palatine return is not routine in preparation for ceramic veneers.
