Effect of Two Types of Surface Treatment of Dental Implants Retaining Mandibular Complete Overdenture on Bone Density Changes

Abstract

Purpose: was to evaluate the influence of surface treatment of implant retained mandibular overdenture on peri-implant bone density. Resorbable Blast Media (RBM) implant surface treatment and acid etched implant surface treatment were used. Materials and Methods: Ten completely edentulous male patients were rehabilitated by mandibular over denture retained by two dental implants in the interforaminal region, the one on the right side was acid etched and the left side was with resorbable blast media (RBM). Peri-implant bone density was assessed with cone beam computed tomography at the time of implant loading, six months and twelve months after denture insertion. Results: There was no significant difference between Acid etched and RBM dental implants on the peri-implant bone density during the follow up period. Conclusion: Within the limitations of the number of studied patients it could be stated that Acid etched and RBM dental implants fulfill the criteria of dental implant success and are recommended to be used.
