Placement of implants in the posterior mandible is limited by the height of bone between the alveolar crest and the inferior alveolar canal. This paper discusses a surgical technique to reposition and protect the neurovascular bundle so that endosseous implants may be placed. A rectangular window is cut in the cortical bone posterior to the mental foramen. The mental foramen is not violated and the mental nerve is not relieved peripherally into the soft tissue. Cancellous bone is removed from the window and the canal is uncovered. A vessel loop placed around the bundle repositions and protects the nerve laterally. After implant placement, the bundle is replaced within the cortical window and the mucoperiosteal flap is sutured. Avoiding manipulation of the terminal branches of the inferior alveolar nerve reduces the risk of permanent nerve damage.
在下颌骨后部植入种植体受到牙槽嵴与下牙槽神经管之间骨高度的限制。本文讨论一种手术技术，用于重新定位和保护神经血管束，以便能够植入骨内种植体。在颏孔后方的皮质骨上切开一个矩形窗口。不侵犯颏孔，颏神经也不向周围软组织游离。从窗口去除松质骨，暴露神经管。将血管环套在神经血管束周围，向外侧重新定位并保护神经。植入种植体后，将神经血管束放回皮质窗口内，缝合粘骨膜瓣。避免操作下牙槽神经的终末分支可降低永久性神经损伤的风险。
