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 CAD/CAM 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 CAD\\CAM 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 ≤ 0.05.
