The color stability and wear resistance of provisional implant restorations: A prospective clinical study

Abstract

Objectives: The aim of the present clinical study was to determine the stability of color and resistance against abrasion and attrition of provisional single implant restorations. Material and Methods: A group of 16 patients were treated with provisional crowns made of Telio CAD. Shortly before the insertion the crowns were photographed and scanned using a 3D-laser scanner. After 8 weeks of clinical usage, the crowns were photographed and scanned again. The vertical occlusal wear and color changes between the restorations were measured. Results: The occlusal plane of the original crown showed a statistically significant reduction of 0.052 mm ± 0.037 mm 8 weeks after placement (p
