Clinical Trial Summary

The aim of this study is to evaluate the clinical behavior of zirconia crowns in dental esthetic zone with vertical versus conventional preparation techniques using a new gradient technology monolithic zirconia (5Y-TZP/3Y-TZP).


Clinical Trial Description

Introduction: A good relationship between dental restorations and the periodontium is one of the most important aspects to ensure clinical success both in terms of esthetics and function. Dental preparation for fixed prostheses can take various forms classified as horizontal preparation with a defined margin (chamfer), or vertical, or without a margin/finish line. According to some clinical reports, vertical preparation technique provides an increases in the gingival thickness and a greater stability of the gingival margin. Moreover, vertical preparation is characterized by being more conservative with tooth structure. Also, taking impressions is easier since it is a finish area and not a defined line. Null hypothesis: 1. There will be no difference between vertical and conventional preparations in the clinical behavior of zirconia crowns in dental esthetic zone at baseline,3,6,9,12 months evaluation. 2. There will be no difference between vertical and conventional preparations in the patient satisfaction of zirconia crowns in dental esthetic zone at baseline,3,6,9,12 months evaluation. ;
