Abstract
The aims of this study were to study the relationship of maxilla and mandible in unilateral cleft lip and cleft palate (UCLCP) and bilateral cleft lip and cleft palate (BCLCP) patients undergoing secondary alveolar bone graft (SABG) and to study the effect of SABG on the growth of maxilla and mandible. This retrospective study was collected data in cleft lip and palate patients who had SABG at Oral and Maxillofacial surgery clinic, Faculty of Dentistry, Khon Kaen University from January 2010 to December 2020. The study was performed by digital measuring the angles and distances from the cephalometric radiographs. The parameters represented the horizontal and vertical relationship and the growth of maxilla and mandible. A total of 21 patients with 18 UCLCP and 3 BCLCP were included in this study. In UCLCP group, we used the marginal homogeneity test to analyze the relationship of maxilla and mandible and Paired T-Test to analyze the growth of maxilla and mandible after SABG. We found that the relationship of maxilla and mandible were not significantly change (p=0.317), and found continual growth of both jaws. In BCLCP group, we used descriptive statistic to explain the change of the relationship of maxilla and mandible and the growth of both jaws. We found that the vertical relationship has change after SABG, by the way maxilla and mandible are still continue to grow. It is concluded that after SABG, the relationship of the maxilla and mandible in UCLCP was not significantly change and the vertical relationship of maxilla and mandible in BCLCP has change. Moreover, the maxilla and mandible still have continual growth in both groups.
