Tumors (benign or malignant), osteoradionecrosis or osteomyelitis sometimes lead to large segmental resections of the mandible. Osteo(cutaneous) fibula free-flaps (OFFF) are used to reconstruct these defects. New anatomical relationships as well as possible irradiation of local tissues make dental rehabilitation complicated. The aim of this study was to determine the rate of dental rehabilitation with an implant-retained lower denture or fixed appliances, after segmental resection and reconstruction of the mandible with an OFFF. Data were obtained from 70 patients, who underwent segmental mandibular resection followed by reconstruction with an OFFF, from 1995 to 2005. Dental rehabilitation was defined as a patient, who after segmental mandibular resection and reconstruction with an OFFF, received an implant-retained lower denture or fixed appliances. Clinical and functional assessments, as well as quality of life and denture satisfaction were evaluated. Twenty-four of 70 patients received dental implants; 18 received complete dental rehabilitation. Only a small percentage of patients with segmental mandibular reconstructions with an OFFF received complete dental rehabilitation, mainly because of poor survival after treatment for malignant tumors of the oral cavity. The beneficial effects of dental rehabilitation with an implant-retained denture or fixed appliances, mainly favored cosmetic aspects, rather than oral function.
肿瘤(良性或恶性)、放射性骨坏死或骨髓炎有时会导致下颌骨的大面积节段性切除。腓骨骨(皮)瓣游离组织移植(OFFF)用于修复这些缺损。新的解剖关系以及局部组织可能受到的照射使牙齿修复变得复杂。本研究的目的是确定在使用OFFF进行下颌骨节段性切除和重建后,采用种植体固位下义齿或固定矫治器进行牙齿修复的比例。数据来自1995年至2005年期间接受下颌骨节段性切除并随后采用OFFF进行重建的70例患者。牙齿修复定义为在下颌骨节段性切除并采用OFFF进行重建后,接受种植体固位下义齿或固定矫治器的患者。对临床和功能评估以及生活质量和义齿满意度进行了评价。70例患者中有24例接受了牙种植体;18例接受了完全牙齿修复。采用OFFF进行下颌骨节段性重建的患者中,只有一小部分接受了完全牙齿修复,主要原因是口腔恶性肿瘤治疗后的生存率较低。采用种植体固位义齿或固定矫治器进行牙齿修复的有益效果,主要体现在美容方面,而非口腔功能方面。
