Most patients sufferfrom denture instability; particularly with mandibular prosthesis, the use of dental implant will be benefit significantlyfrom even a slight increase in retention. The concept of implanting two to four fixtures in a bony ridge to retain acomplete denture prosthesis appealing therefore, as retention, stability and acceptable economic compromise tothe expanse incurred with the multiple fixture supported fixed prosthesis .Materials and methods in this study the sample were eight patients selected from a hospital of specialized surgery,these patient were wearing a mandibular implant retained over denture for two years these patients having MIR-ODwith Bar-clip, ball-cup and O- ring attachments. Preparative radiography was obtained for this patient from thecenter .these radiograph was taken to the patient at time of insertion. The second radiograph image was taken tothe patient after two years of function with prosthesis. .the scanned images were transfer to special folder in acomputer then analysis of bone loss done using Dimax software. After that an accurate calibrations of crestal bonemeasurement were analyzed for both groups of Radiography .Results it was appeared that the amount of bone loss in ball and bar designs (of mandibular Implant retainedoverdenture) were within the criteria of successful rate of bone loss during the period of examination, and there wasstatistically significant difference between both types of anchorage system.Conclusions The amount of bone loss was 0.1 mm after two years follow up, and it was within the acceptable limits ofbone lose. A significant difference appeared between both designs of MIR-OD, Ball and bar designs
