In this paper, we report a case of a wide jawbone-anchored prosthetic device for full dental rehabilitation after resection of the left upper gingival carcinoma in situ.
An 87-year-old woman was referred to our department because of left upper gingival pain. Histological diagnosis was gingival carcinoma in situ of the left upper gingiva and leukoplakia of the right upper gingiva. Bilateral maxillary tumor extirpation and two dental implant placements were carried out. After surgery, the masticatory function decreased because the ability to maintain the denture was extremely decreased. Because exposed necrotic bone was observed in the left anterior maxilla, the sequestrum was extirpated and two dental implants were placed into the left posterior maxillary bone 7 months after the first surgery. One year 3 months later, we applied an implant-supported prosthesis with locator attachment for postoperative maxillary gingival carcinoma in situ. As a result, the masticatory function and QOL were remarkably improved. Although 4 years have passed since the implant superstructures were placed, the patient has followed a favorable clinical course.
