A clinical evaluation of an implant-supported overdenture placed in the edentulous mandible after hemiglossectomy is described. The deltopectoral flap covering the mandibular ridge was replaced with a free mucosal graft. Four Brånemark system implants were inserted into the anterior part of the mandible, but one of the four fixtures did not show osseointegration. The superstructure was designed as a spaced round bar-attachment supported by three implants so as to retain the complete overdenture. In addition to the metal clip, a silicone-based soft denture liner material was applied in the female portion of the attachment so as to prevent the attachment from making a clattering noise upon mastication. Although the overdenture required adjustment at regular intervals, the treatment was successful both aesthetically and functionally for up to at least 10 years.
本文描述了对半侧舌切除术后无牙下颌植入支持式覆盖义齿的临床评估。覆盖下颌牙槽嵴的三角胸肌皮瓣被游离黏膜移植所替代。在下颌前部植入了4枚Brånemark系统种植体，但4枚种植体中有1枚未显示骨结合。上部结构设计为由3枚种植体支持的带间隙圆杆附着体，以保留全口覆盖义齿。除金属夹外，在附着体的母件部分应用了硅酮基软义齿衬垫材料，以防止附着体在咀嚼时发出咔嗒声。尽管覆盖义齿需要定期调整，但该治疗在美学和功能上至少成功维持了10年。
