Abstract
Introduction: The implant supported overdentures offered better chewing and masticatory functions. Locator attachment has more advantages than other attachment types. Aim: The aim of the study was to compare radio-graphically the effect of implant locator’s height on peri-implant bone height and density in mandibular over-denture. Patients and method: Twelve completely edentulous male patients had received conventional complete maxillary dentures and mandibular overdenture that retained by two implants that were inserted in the canine region by the help of CAD/CAM based surgical guides. The patients were divided randomly into two groups. Group I: the patients were received locator abutment with 1mm in height. Group II: the patients were received locator abutment with 3mm in height, a series of cone beam radiographs were taken at 0, 6, 12 and 18 months starting from the first day of lower over denture installation, peri-implant bone changes regarding height and density were estimated. Results: It was found that the mean marginal bone loss measurements were relatively higher for group I than group II with non-statistical significant difference. The average difference in bone density measurements around the implants for both groups showing initial increase followed by marked decrease through the follow up periods. Conclusion: locator height has an effect on peri-implant bone height, bone density.
