Effect of using zirconia and metallic bar attachment overdentures on the supporting structures of mandibular edentulous ridge area (Randomized control trial)
Statement of Problem: Mandibular conventional denture is no longer the most appropriate first choice of treatment, nowadays implant retained overdentures proved to be a predictable and effective method as compared to complete dentures. Purpose: The aim of the present study was to evaluate the effect of using zirconia and metallic bar attachment overdentures on peri-implant supporting tissue clinically for implant-supported overdentures in the mandible during a year period. Materials and Method: Twelve completely edentulous patients had two inter-foraminal implants. The patients divided randomly into two equal groups. Six patients received zirconium bar attachment system and the other group received metallic (Cr-co) bar attachment, modified plaque index was obtained for both groups. Results: No implants were lost from baseline to a year registration. Metallic bar attachments showed significant plaque accumulation than zirconium bar attachments. Conclusion: There was better modified plaque index for zirconium bar attachment.
