ABSTRACT
The pain following oral grating surgery is varied from patient to another. This matter takes a great attention from the patient during the distinguishing the operation with him. So, the aim of this study is to assess the pain following the harvesting of autogenous bone from the symphysis. 9 patients received alveolar ridge grafting. Two scales were used; the first had a list of four degrees:1]no pain,2]slight pain,3] moderate pain, 4]severe pain. The second scale was ranged from 0 to 100, and the patient defined the number that conform with his pain. In the first scale and after 3 hours: 3 patients felt no pain, 4 patients felt slight pain, 2 moderate pain and any did not felt sever pain. While in the second scale and after 3 hours: The pain severity average was 31,78%, and after 48 hours was 15,11%, and after one week was 3,33%. The operation of alveolar ridge augmentation using bone grafts harvested from chin symphisis is followed by a slight and moderate pain similar to other routine oral surgeries.
