Efficiency of Er: YAG Laser in Veneers Debonding with Two Materials & Thicknesses-An in Vitro Study
Abstract:Objective: To evaluate shear bond strength of laminate veneers after debonding attempt using: Er:YAG laser on two different ceramic materials: Lithium disilicate glass ceramic material and cubic zirconia, in two thicknesses: 0.3mm. 0.7mm. Materials and Methods: Fifty-six freshly extracted maxillary premolars were collected, examined and those with cracks or structural defects were discarded. The premolars were stored in saline during the study. The extracted teeth were embedded in acrylic resin blocks for fixa… Show more
