Abstract
-
PURPOSE: This study is conducted to evaluate the clinical success of secondary alveolar bone grafting using autogenous iliac particulate cancellous bone marrow in cleft maxilla.
MATERIALS AND METHODS
We evaluated 107 cleft patients who had been admitted to the Dept. of Oral and Maxillofacial Surgery of Pusan National University Hospital from January 1, 1991 to January 31, 1999 and had been performed secondary alveolar bone grafting with autogenous particulated cancellous bone marrow from iliac crest.
RESULTS
1. Men were 70 and women were 37, which shows 65.4% and 34.6% and the proportion of males to females was 1.9:1. Unilateral cases were 89(83.2%) and bilateral cases were 18(16.8%). 2. Age of bone grafting is widely distributed from 7 to 29, and the average was 13.2. 3. Success rate was 97.8% in unilateral cases, 94.4% in bilateral cases. Overall success rate was 96.7%. 4. We evaluated the bone graft contour by the percentage of bone attachment level adjacent to the alveolar cleft and the mesial side showed 82.4% and the distal 87.7%. 5. The amount of notching the alveolar ridge at the grafted site through the ratio of notching length up to the most apical base to the length of proximal segment anatomic root was 0.19.
