The long-term prognosis for osseointegrated implants has been proven and implant therapy is recognized as a highly predictable treatment method. In particular, implant prosthesis is recognized as the most predictable treatment. Here, we present a patient in whom occlusion was favorably restored by replacing missing mandibular molars with implants and making a maxillary overdenture.<BR>The patient was a 59-year-old man who visited our institution with the chief complaint of poor denture fit. At the initial visit, 33-7, 5-578 were confirmed along with chronic periodontitis, apical periodontitis and caries. The patient wore an upper denture and a mandibular prostheses that had a poor fit. Occlusion was unstable due to the lack of occlusal support in the right molar region. As basic periodontal treatments, 7, 58 with poor prognoses were extracted; scaling, root planing, caries control, and root canal were performed; and a therapeutic denture was prepared. After reassessment, periodontal surgery was performed on the remaining maxillary teeth, and dental implants combining autologous bone grafting and GBR were placed for the missing mandibular molars. During the second surgery, keratinized tissue around the implants was achieved, and after restoring occlusal function by provisional restoration, the final prostheses were placed. Also, a maxillary overdenture with magnetic attachments was prepared. At present, the periodontal tissue and occlusion are stable, and the patient has been doing fine.
