背景：在缺牙区放置骨内种植体常常受到剩余牙槽嵴骨量不足的限制。在种植体植入前，下颌骨局部植骨是牙槽骨重建的一种方便的自体骨来源。目的：本研究的目的是记录和比较两个口内供骨部位（下颌联合和下颌升支）的发病率和并发症发生频率。材料和方法：本研究回顾了53例连续治疗的患者：自体下颌骨联合植骨29例，下颌升支植骨24例。每个病人接受了一份问卷调查18个月后，手术后可能发生的问题，在optimal period.RESULTS：在患者中，骨收获从下颌升支，有较少的术后症状，手术后立即比下颌骨联合收获。29例联合移植患者中，有22例在手术后1个月出现受颏神经支配的皮肤敏感性下降。24例支移植患者中有5例出现前庭粘膜敏感性下降，与颊神经的神经支配相对应。手术后18个月，联合组29名患者中有15名仍然存在一定程度的敏感性下降，并出现永久性感觉改变。只有一个病人从下颌升支移植出现永久性改变后前庭区的感觉。53例患者中无一例发生严重并发症。结论：本研究结果支持下颌升支作为口内供骨区进行植骨。
BACKGROUND: The placement of endosseous implants in edentulous areas is frequently limited by inadequate bone volume of the residual ridge. Local bone grafts from the mandible are a convenient source of autogenous bone for alveolar reconstruction prior to implant placement.PURPOSE: The aim of the present study was to document and compare the morbidity and the frequency of complications occurring at two intraoral donor sites: the mandibular symphysis and the mandibular ramus.MATERIAL AND METHODS: This study reviewed 53 consecutively treated patients: 29 with autogenous bone grafts from the mandibular symphysis and 24 with mandibular ramus bone grafts. Each patient received a questionnaire 18 months after surgery regarding problems that may have occurred during the postoperative period.RESULTS: In the patients in whom bone was harvested from the mandibular ramus, there were fewer postoperative symptoms immediately after the operation than with mandibular symphysis harvesting. Twenty-two of the 29 patients with symphysis grafts experienced decreased sensitivity in the skin innervated by the mental nerve 1 month after the operation. Five of the 24 patients with ramus grafts experienced decreased sensitivity in the vestibular mucosa corresponding to the innervation of the buccal nerve. Eighteen months after the surgery, 15 of the 29 patients in the symphysis group still had some decreased sensitivity and presented with permanent altered sensation. Only one of the patients grafted from the mandibular ramus presented with permanent altered sensation in the posterior vestibular area. No major complication occurred in the donor sites in any of the 53 patients.CONCLUSION: The results of this study favored the use of the ascending mandibular ramus as an intraoral donor site for bone grafting.
