Abstract
Aim: The aim of the study was to evaluate the wear of reinforced acrylic denture teeth and nano-filled composite denture teeth. Materials and methods: A split mouth randomized clinical trial where 48 teeth of each group were inserted in complete dentures for 6 patients. The control group was reinforced acrylic denture teeth and the intervention group was nano-filled composite denture teeth. Surface wear was measured using an optical scanner. Surface topographies for each tooth were analyzed using WSxM software at baseline, 0, 3 and 9 months follow up. Results: For the effect of time, the highest mean value was found in baseline group followed by 9 months and 3 months groups, while the least mean value was found in 6 months group. For the effect of groups: The highest mean value was found in the nano-filled composite denture teeth, while the least mean value was found in reinforced acrylic denture teeth. Conclusion: Nano-filled denture teeth have better wear resistance than the reinforced acrylic denture teeth. Nano- filled denture teeth are expected to show long term functional efficiency.
