In vivo prospective randomised study of the wear of dental restorations using an intraoral scanner and its correlation with visual assessment

Abstract

This study aims to evaluate the efficacy of the True Definition® intraoral scanner in quantifying the wear of glass ionomer restorative materials (KetacTM Universal and KetacTM Molar) over 1 year. It also aims to study the correlation between visual and digital assessments of restoration wear. For that purpose the study assesses a clinical follow-up study of a post-marketed material with a prospective, controlled, randomised, split-mouth, and blinded assessment design. Intraoral optical impression and visual assessment were carried out over three appointments over 12 months, starting with 36 patients.
