Abstract

ABSTRACT

Aim: The purpose of this study was to evaluate radiographically the effect of using (Nano-hybrid composite resin teeth and Cross linked acrylic denture teeth) materials on marginal bone height changes around implant retained mandibular overdenture using digital radiography (digora). A comparative study. Materials and Methods: Twelve completely edentulous patients were randomly divided into two groups according to the artificial teeth material used in complete denture. One group received complete dentures with cross-linked acrylic resin teeth and the other group received complete dentures with Nano-hybrid composite teeth. Digital radioghraph was taken at the delivery, 6 months and 12 months follow -up appointments. The evaluation was done for marginal bone height changes around implants. Results: Analysis was done by using two-tailed t-test revealed that increase in amount of bone loss in both groups which is in favor to patients wearing dentures with Nano-hybrid composite resin teeth. Conclusion: Nano composite resin teeth materials compared favorably to acrylic resin teeth materials on the supporting structures of implant retained mandibular overdentures.
