Brief Summary:
Purpose This study aimed to assess the 3-dimentional wear 3D volumetric loss and 2-dimentional wear 2D vertical loss and surface hardness of ready-made prefabricated and CADCAM milled artificial denture teeth
material and methods In a cross-over study design ten completely edentulous patients were randomly chosen for this study and given two complete dentures The first complete denture was constructed with pre-fabricated teeth The second complete denture was constructed with CADCAM milled teeth The complete denture teeth were 3D scanned at the time of insertion T0 after three months T3 and after six months T6 of denture insertion Utilizing 3D surface superimposition techniques the vertical 2D wear and Volumatic 3D wear material loss were measured The hardness of the teeth were evaluated at the time of denture insertion T0 then after 6 months T6 of denture insertion by Vickers hardness test Statistical analysis was done using SPSS software Paired groups were compared by paired t test Significant difference was considered if P 005
