TetricCAD Crown Clinical Study

Fractured Tooth Clinical Trial

Official title: Clinical Evaluation of Chairside CAD/CAM Resilient Ceramic Crowns

Status Active, not recruiting

Clinical Trial Summary

This investigation will be a clinical trial to study the performance of a new resin-based ceramic material for crowns. The material has been approved by the FDA for patient treatment. A computer technique will be used to fabricate the crowns in a single appointment without the need for a temporary crown or second appointment. The purpose of the study is to measure how well the high strength crowns function over an extended period of time.

Clinical Trial Description

The study will be composed of 50 crowns placed in adult patients that have been identified as requiring at least one crown on a posterior tooth. A maximum of two crowns per patient will be completed. All the crowns will be made from the same resilient ceramic CAD/CAM block(Tetric CAD/Ivoclar Vivadent). The crowns are placed using an adhesive bonding process including a total etch process with a universal adhesive (Adhese by Ivoclar Vivadent) and dual-cured resin cement (Variolink Esthetic by Ivoclar Vivadent). The crowns are planned to be evaluated at 6 months, 1 year, 2 years, 3 years, and if funding permits, 4 years, and 5 years. At each appointment, an examination of the crown will be completed as well as clinical photographs, an intraoral digital scan, and impression of the crown. ;
