Abstract
Aim: The purpose of this study was to compare the effect of using two different designs of magnet attachment (flat and dome) and ball and socket attachment on crestal bone around implant in implant –supported Mandibular Overdenture.
Materials and methods: Fifteen completely edentulous patients were randomly divided into three groups. Group I for two implants supported overdenture with flat magnetic attachment, Group II for two implants supported overdenture with dome magnetic attachment and Group III for two implants supported overdenture with ball and socket attachment. Implant fixtures were inserted surgically at the canine area. Each patient was recalled two months after implant insertion for superstructure placement. Marginal Bone loss around the implant were measured at 0, 3, 6 months and 12 months after over denture pickup and all data were gathered and tabulated.
Results: A statistically significant difference for bone resorption was showed among (3 m), (6 m) and (12 m) where (p < 0.001) for each attachment groups. By comparison for three groups at (3 m), (6 m) and (12 m) a statistically significant difference was showed among (Ball and socket) and each of (Dome magnet) and (Flat magnet) attachments where (p < 0.001) and no statistically significant difference was showed among (Dome magnet) and (Flat magnet) attachments.
Conclusion: The current study concluded that the dome magnet attachment and flat magnet attachment transmit less stress to the implants when compared to ball attachments resulting in reducing the crestal bone loss amount around the dental implants when used in implant supported mandibular over denture.
