Abstract
Aim: The aim of this study is to evaluate the effect of PRF membrane on recovery of neurosensory disturbance of the inferior alveolar nerve following IAN lateralization surgery for immediate implant placement. Methodology: Cases were selected from the oral and maxillofacial surgery outpatient clinic of the academic hospital of the Faculty of dentistry Cairo University-Egypt. A total of 12 inferior alveolar nerve lateralization surgeries were performed on eight patients. Six mandibular sides underwent IAN lateralization surgery and the nerve was surrounded by PRF membrane and six sides underwent IAN lateralization surgeries and the nerve was left to lie against the implant surface.The neurosensory disturbance were examined through subjective ,objective and electrophysiological examination pre operatively and postoperative at 1 week,2weeks,1 month,3 month and 6 month. Results: There were no statistically significant differences between the two groups in most of follow up intervals regarding the subjective, objective and electrophysiological tests. Conclusions: the PRF membrane did not improve the recovery of the postoperative NSD of the inferior alveolar nerve following IAN lateralization surgery for immediate implant placement
