| Abstract | ||
| Purpose: This study was carried out to evaluate radiographically the effect of different treatment modalities (All on 4 Concept or 4 implant in interforaminal region) on prei-implant bone height changes of implant supported mandibular overdenture using CBCT. Methodology: Fourteen completely edentulous patients were selected according to the inclusion and exclusion criteria and divided randomly into 2 groups. Group 1: seven completely edentulous patients were rehabilitated with upper complete denture and lower implant supported hybrid prosthesis using All on 4 concept and group 2 seven completely edentulous patients were rehabilitated with upper complete denture and lower implant supported hybrid prosthesis using four straight implants in anterior intra foraminal region . Bone height changes were evaluated at 0, 6, 12 month after insertion of prosthesis. All data was collected , tabulated & stastistically analyzed. Results: The results of this study showed more marginal bone loss around tilted implants in All on 4 concept than straight posterior implants in the second group. Conclusion: Tilted posterior implants in All on 4 concept induce more bone resorption than straight posterior one. | ||
