The conventional method of harvesting full cortical bone from the mandibular ramus was reported to have associated complications ranging from postoperative pain and swelling to impaired inferior alveolar nerve function.
A modified ramal bone harvesting technique is described in which partial cortical-type bone is harvested from the mandibular ramus and used for an autogenous bone graft.
Partial-thickness cortical bone was harvested without paresthesia while reducing postoperative discomfort and complications. Sufficient bone was obtained for ridge augmentation and eventual implant placement.
Non-invasive partial cortical ramal bone harvesting is a reproducible and predictable technique for preventing nerve damage while providing sufficient block bone needed for a dental implant.
据报道，从下颌支获取全皮质骨的传统方法会伴有多种并发症，从术后疼痛和肿胀到下牙槽神经功能受损。
描述了一种改良的下颌支骨采集技术，即从下颌支采集部分皮质型骨并用于自体骨移植。
获取了部分厚度的皮质骨，且未出现感觉异常，同时减少了术后不适和并发症。获得了足够的骨用于牙槽嵴增高及最终的种植体植入。
非侵入性部分皮质下颌支骨采集是一种可重复且可预测的技术，可预防神经损伤，同时提供牙种植所需的足够块状骨。
