| Abstract | ||||
| Purpose: To evaluate the effect of different denture base materials on peri-implant bone changes (height & density) in implant-supported mandibular over-denture. Subjects and methods: Eighteen completely edentulous male patients were selected and rehabilitated by mandibular overdenture supported by two dental implants in the canine region. Patients were divided into three groups, six patients in each. Group I: patients received overdenture made from conventional heat-cured acrylic resin. Group II: patients received overdenture made from thermoplastic acrylic resin. Group III: Patients received overdenture made from (CAD/CAM) acrylic denture base. Peri-implant bone height and density were assessed with cone beam computed tomography (CBCT) at the time of denture insertion, six and twelve months after denture insertion. Results: There was a significant difference in bone height changes (p≤ 0.05) but a non-significant difference in bone density (p< 0.05) between the three studied groups. Where group II showed a higher value in bone height changes and density followed by Group III while group I was the least one. Conclusion: The use of thermoplastic acrylic resin as well as (CAD/CAM) technology in manufacturing implant-supported overdenture bases was of great benefit to preserve the implant-supporting structures regarding bone height and density than conventional acrylic resin bases. | ||||
