Ceramic Versus Composite in the Treatment of Posterior Teeth by Inlays or Onlays — CECOIA  

Dental Caries Clinical Trial

Official title:
Ceramic Versus Composite in the Treatment by Inlays or Onlays of Posterior Teeth Affected by Tooth Substance Loss : a Multicenter Randomized Controlled Trial

Clinical Trial Summary

The main purpose of this trial is to determine which material, between ceramic and composite, is best to manufacture dental inlays and onlays in the treatment of moderate dental substance losses, generally due to dental caries. Restorations will be done using direct Computer Assisted Design and Manufacturing (CAD-CAM). Another aim of this study is to determine which factors influence the success of these restorations.

Clinical Trial Description

WHO estimates dental caries prevalence to be over 90% adults worldwide. When tooth substance loss due to the decayed tissue is small, a filling is done by the dentist directly. When the substance loss is important, dentists often treat it with a crown, which presents the disadvantage of further mutilating the tooth. An intermediate technique consists in manufacturing an inlay or an onlay: these restorations become more and more common since they are a minimally invasive solution in such cases. Inlays and onlays can be made of metal, ceramic or composite. Patients tend to refuse metallic restorations, so that dentists generally have to choose between composite and ceramic. Composite wears whereas ceramics fracture. Published in vitro studies provide possible answers to which material is most effective but very few clinical studies have been conducted to confirm them. Material\'s choice for inlay manufacturing is thus more country-based than evidence-based (Most french dentists choose composite while US dentists prefer ceramics for example). The main objective of this trial is to compare the clinical performance of ceramic and composite inlays/onlays. Other objectives include looking for the prognostic factors of these restorations and validating the criteria proposed by the World Dental Federation (FDI) to evaluate dental restorations. ;
