METHODS A 60-year-old woman presented to the Clinic at Health Science University of Hokkaido on September, 1997. The patient's chief complaint was difficulty in chewing due to pain with tooth clenching of a fixed partial denture in the left mandible. This clinical report describes a treatment approach using implant-supported fixed prostheses by two dental implants after extraction of the abutment teeth. CONCLUSIONS She tried to use the fabricated mandibular removable partial denture but disliked the lingual bar. After discussing a treatment plan using implant-supported fixed prostheses, a decision was made to place implants in the free-end partially edentulous mandible. CONCLUSIONS The patient was followed for 4 years with no surgical or prosthetic complications. It is suggested that a dental implant for prosthetic treatment may improve the quality of life of the patient.
