TetricCAD Crown Clinical Study
Clinical Evaluation of Chairside CAD/CAM Resilient Ceramic Crowns
Sponsor: Ivoclar Vivadent AG
This observational or N/A phase trial investigates Decayed Tooth and Fractured Tooth and is currently completed. Ivoclar Vivadent AG leads this study, which shows 14 recorded versions since 2018 — indicating substantial longitudinal coverage. The change history captured here reflects the iterative nature of clinical trial conduct.
Study Description(click to expand)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.

Eligibility 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.
