A Radiographic Review of Bone Levels Around Calcitek Dental Implants Supporting Mandibular Overdentures. Preliminary Results at 3 to 6 Years.

Abstract - This retrospective study aimed to measure marginal bone resorption around cylindrical hydroxyapatitecoated implants retaining mandibular overdentures and compares this between two- and four- implant supported overdentures. Twenty three edentulous patients received 66 implants in their anterior mandible and were restored with overdentures. Panoramic radiographs one week post-operatively and at last recall were compared and marginal bone loss calculated. The mean recall interval was 51.22 months. The mean cumulative bone loss was 1.08mm and the mean annual bone loss 0.263mm. There was no significant difference between two- and four- implant overdentures. The results were comparable with other reports.
