Radical surgery was performed to remove the left side of the mandible in a patient diagnosed with mandibular carcinoma. For 36 years, the patient functioned with a hinged, removable partial denture anchored to the remaining natural dentition on the mandibular right side. Because of deterioration of the remaining natural dentition, the patient could no longer function with the partial denture. In lieu of reconstruction with a bone graft, the patient chose to undergo treatment with osseointegrated implants to permit insertion of a stable prosthesis with a cantilevered extension into the area of the surgical resection. The rigid attachment of the prosthesis to the remaining mandible provided function as well as soft tissue support in the area of the surgical defect.
对一名被诊断为下颌癌的患者进行了根治性手术，切除了下颌骨左侧。36年来，该患者一直使用一种铰接式可摘局部义齿，该义齿固定在下颌右侧的剩余天然牙列上。由于剩余天然牙列的恶化，患者无法再使用该局部义齿。患者选择接受骨整合种植体治疗，而不是进行骨移植重建，以便能够插入一个带有悬臂延伸的稳定假体到手术切除区域。假体与剩余下颌骨的刚性连接在手术缺损区域提供了功能以及软组织支撑。
