Abstract

Introduction: Implant supported overdentures may be used as an alternative to fixed bridges especially in edentulous patient who can not afford the high cost of fixture placement. The overdenture may be attached to the implant by one of several methods. One of them is magnet. Advantages with magnet include a simplified dental technique and reduced lateral stresses on the abutment. The aim of our study was to determine the rate of succes rate of magnet in implant supported overdentures through clinical and histological analysis. Materials and Metheds: Seven patient received above overdentures with magnetic retention. The course of study was 4 years. The patient had been edentulous for several years and were unable to function with a lower denture due to lack of retention and stability. Such a problem had not been solved by a conventional approach. The implants and magnet selected from Dyna company. Results: The use of implant and overdenture with magnetic attachment was an appropriate alternative for patients who have totally flat jaw and no better option than magnet overdenture. In this study, two magnets with 500gr/f yielded a good retention for prosthesis so nutrition, phonetic and esthetic needs were resolved. No side-effect from magnet on peri-implant soft tissue was observed. The gingival sulcus was 2.08mm and the bone loss was 1.23mm after one year. Magnet resistance to corrosion was very little and the need for changing of magnet after the course of study was obvious. Conclusion: Use of magnet and overdenture supported by implant in patients with totally flat jaw, who could not be treated by any other technique, is an appropriate alternative.
