ABSTRACT
Clinical evaluation of the Neural complication after harvesting of mandibular ramus block grafts, by testing the mento-labial sensory disturbance and the vitality of teeth in the ipsilateral side. 13 patient [7 male-6 female] aged 19-47 years [mean 30.3] was included in this study where 15 ramus block grafts was harvested for alveolar ridge augmentation before implant placement, and the study was done in the oral and maxillofacial surgery department and implant clinics in Damascus university-dentistry school, all patients were followed up for 1 week-1 month-2 month- 4 month by testing the labio-mental sensory and the thermal pulp response, the statistical analysis was made by Cochran's Q test [p value<0.05].
