目的临床研究双层腓骨移植联合牙种植在下颌咬合功能重建中的价值。方法选择青岛大学附属医院口腔颌面外科2012年8月~2015年3月间8例行下颌骨节段性截骨的患者,一期行双层腓骨瓣修复下颌骨缺损,二期在移植腓骨上行牙种植,恢复缺损区的咬合关系,临床观察其骨移植及种植术后咬合功能的重建情况。结果 8例患者的移植腓骨均成活,一期愈合良好,双层腓骨恢复了足够的下颌骨高度,为二期牙种植创造了良好的骨床条件。二期的牙种植手术均获成功,义齿修复后,咬合功能恢复良好。随访0.5年到3年,种植体无脱落。结论双层腓骨移植联合牙种植是一种良好的下颌骨节段性缺损后咬合功能重建的方法。
Objective To investigate the value of double fibula transplantation combined with dental implant in functional reconstruction of mandibular bite. Methods Eight patients with mandibular segmental osteotomy underwent oral and maxillofacial surgery in Affiliated Hospital of Qingdao University from August 2012 to March 2015. The patients underwent bilateral fibular flap repair in the first phase and the second fibula Dental implants, restoration of the occlusion of the defect area, the clinical observation of the bone graft and implant surgery bite function reconstruction. Results All the 8 patients survived the fibula graft. The primary fibula was healed well in one case. The bony fibula recovered enough height of the mandible and created a good bone bed condition for the second dental implant. Two dental implant surgery were successful, denture repair, bite function recovered well. Follow-up 0.5 to 3 years, no loss of implant. Conclusions Bilateral fibular graft combined with dental implants is a good method of functional reconstruction of posterior segment of mandibular segmental defects.
