Abstract

PURPOSE

The present case describes an inferior alveolar nerve lateralization for implant placement that caused mandible fracture a few days after surgery.

CLINICAL REPORT

In this case, a 56-year-old female patient who had a severely atrophied jaw and showing bone height less than 7 mm from the bone crest and the mandibular canal was submitted to surgery lateralization of the inferior alveolar conducted with piezzo. Even with all postoperative care, the patient suffered an incomplete fracture of the mandible a few days after lateralization of the inferior alveolar nerve for implant placement. The patient was treated with soft diet and medications for pain and antibiotics, besides removing the implant associated with the fracture.

CONCLUSION

It is suggested that this procedure may be conducted in 2 operative periods: firstly, the lateralization of the inferior alveolar; and secondly, after a period of 3 months, the implant placement in a situation of more bone stability.

摘要

目的

本病例描述了一例在植入种植体时进行下牙槽神经侧方移位术，术后数天导致下颌骨骨折的情况。

临床报告

在此病例中，一名56岁女性患者，下颌严重萎缩，牙槽嵴距下颌管的骨高度小于7毫米，接受了使用超声骨刀进行的下牙槽神经侧方移位术。即便术后进行了所有护理，在为植入种植体而行下牙槽神经侧方移位术后数天，患者仍发生了下颌骨不完全骨折。除了取出与骨折相关的种植体之外，患者接受了软食饮食，并使用了止痛药物和抗生素进行治疗。
