In oral, cranio, and maxillofacial surgery, a close relationship among the bone, nerves, and blood vessels can be regularly observed. Surgical procedures for the removal of dental implants have the potential to cause vascular injury and bleeding in the floor of the mouth and internal anterior region of the mandible. Furthermore, conventional osteotomy techniques always require extensive protection of adjacent soft tissue because cutting is not limited to bone and could easily affect other tissues when applied improperly. We report the removal by means of piezosurgery of a malpositioned osseointegrated implant that had previously caused a sublingual hematoma during its insertion. The postoperative course was uneventful, no bleeding, infection, or hematoma formation was noted and the patient reported 100% resolution of all symptoms.
在口腔颌面外科中，经常可以观察到骨骼、神经和血管之间的密切关系。牙种植体取出的手术程序可能导致口腔底部和下颌骨前内侧的血管损伤和出血。此外，传统的截骨技术总是需要广泛保护相邻的软组织，因为切割不仅限于骨骼，而且在应用不当时很容易影响其他组织。我们报告了一例通过超声骨刀取出先前在插入过程中引起舌下血肿的错位骨整合种植体的情况。术后过程顺利，无出血、感染或血肿形成，患者报告所有症状均 100%缓解。
