摘要
During implantology procedures, one of the most serious complications is damage of the inferior alveolar nerve (IAN). The mandibular incisive nerve is described as a terminal branch of the IAN and provides innervation to the lower anterior teeth and canines. The incisive nerve and canal are located in the interforaminal area. Although numerous studies report IAN damage during implant placement, few reports in the literature describes sensory disturbances, such as neuropathic pain, related to mandibular incisive nerve damage. The purpose of this retrospective clinical study was to evaluate the risk of neuropathic pain caused by implant placement in the interforaminal region of the mandible. Panaromic radiographs of patients who were treated with dental implants in the Department of Maxillofacial Surgery, Faculty of Dentistry at Erciyes University, between 2007 and 2012, were examined. Fifty-five patients with suspected relationship between mandibular incisive canal and dental implant were included into this study. Computed tomography scans were obtained from 10 patients who have postoperative neuropathic pain. Relationship between dental implant and mandibular incisive nerve was evaluated using a three-dimensional software program. Mandibular incisive nerve perforation by at least 1 implant was observed in all 10 patients. Descriptive analyses were also provided. Neuropathic pain may occur after implant placement in the interforaminal region due to the perforation of the incisive canal and nerve. According to the results of this retrospective study, the incisive canal and nerve perforation should be considered as a complication of implant surgery in the mandibular anterior area.
