The results obtained with a modified surgical technique for transposition of the inferior alveolar nerve followed by immediate placement of endosseous implants in mandibles with moderate to severe atrophy are presented. Ten transpositions of the inferior alveolar nerve together with the installation of 21 implants were performed in six patients. The mean postoperative follow-up time was 23 months, with a range of 12 to 46 months. All implants with functioning pontics remained stable, with no mobility nor signs or symptoms of pain and infection during the follow-up period. Postoperative radiographic evaluation disclosed no pathologic bone loss around the implants. Neurosensory evaluation was performed using the two-point discrimination test. One patient with unilateral transposition had objective neurosensory dysfunction at 12 months postoperative, although all the nerve function were reported as normal by the patients. Strict patient selection criteria are necessary, with full awareness by the patient of the possibility of long-term or even permanent nerve paresthesia, when this procedure is contemplated.
本文介绍了一种改良手术技术用于下牙槽神经移位，随后在中度至重度萎缩的下颌骨中立即植入骨内种植体所获得的结果。对6例患者进行了10次下牙槽神经移位并植入21枚种植体。术后平均随访时间为23个月，范围为12至46个月。所有带有功能桥体的种植体均保持稳定，随访期间无松动，也无疼痛和感染的迹象或症状。术后影像学评估显示种植体周围无病理性骨吸收。使用两点辨别试验进行神经感觉评估。1例单侧移位患者术后12个月存在客观神经感觉功能障碍，尽管患者报告所有神经功能均正常。当考虑采用该手术时，严格的患者选择标准是必要的，且患者应充分了解长期甚至永久性神经感觉异常的可能性。
