A conversion to implant assisted removable partial denture infailed fixed implant prosthesis of mandible: A case report / 대한치과보철학회지

ABSTRACT

Failure of fixed implant supported prosthesis is caused by biomechanical factors such as excessive occlusal stress and biological factors such as bacterial infections andinflammation. Implants with severe bone resorption that have worsened without being resolved due to implant complications should be removed and then new treatmentsshould 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 partialdenture (IAPRD) treatment is performed using implant surveyed bridge as abutment. Through this treatment, the clinical results were satisfactory on aspect of masticatoryfunction recovery and oral hygiene management. (J Korean Acad Prosthodont 2020;58161-8)
