Abstract

Failure of fixed implant supported prosthesis is caused by biomechanical factors such as excessive occlusal stress and biological factors such as bacterial infections and inflammation. Implants with severe bone resorption that have worsened without being resolved due to implant complications should be removed and then new treatments should be planned, taking into account remaining teeth, remaining implants, and residual alveolar. The patient of this case removed some of fixed implant prosthesis of mandible. The condition of the remaining alveolar bone was reassessed for further implant replacement and a few implants were placed. Then implant assisted removable partial denture (IAPRD) treatment is performed using implant surveyed bridge as abutment. Through this treatment, the clinical results were satisfactory on aspect of masticatory function recovery and oral hygiene management. (J Korean Acad Prosthodont 2020;58:161-8)
