| Abstract | ||||
| Objectives: This study was conducted to evaluate the effect of metallic (cobalt chromium), glass fiber and nano zirconia oxide reinforcement of acrylic resin denture base on the peri-implant crestal bone level changes in palateless locator retained maxillary over denture. Materials and Methods: Twenty-one completely edentulous male patients with maladaptive experience to maxillary dentures were selected to participate in this study. For all patients maxillary four implant-retained overdenture was constructed following the same basic principles. Every patient received four implants, two in the canine region with (3.6 mm in diameter & 12mm in length), and two in the second premolar region with ( 4.5 mm in diameter & 8mm in length); (Tiologic® Implants, Dentaurum, Ispringen, Germany) . Metal (cobalt chromium) reinforced over denture was constructed for the first group , while 5% fiber reinforced acrylic resin denture was constructed for the second group and Overdenture was reinforced using 5% of nano ZrO2 for the group three patients. . Follow up visits were scheduled twelve and twenty four after implant loading for inspection of the prosthesis and radiographic evaluation Peri-implant crestal bone level changes were assessed using intra-oral radiographs taken . Results: The findings of the present study demonstrates that all the studied denture base reinforcement materials individually showed significance bone loss around implants (p < 0.05) after 12 months follow up period. Conclusion: Within the limitations of this study, reinforcement of polymethyl methacrylate denture base with glass fiber or nano zirconia oxide should be considered in palateless implant retained maxillary over denture. | ||||
