Abstract
BackgroundWe evaluated and compared the outcomes of different ossification processes in patients with alveolar cleft in whom correction was performed using endochondral bone graft or intramembranous bone graft.MethodsThe patients were divided into two groups: the endochondral bone (iliac bone or rib bone) graft group and the intramembranous bone (mandibular bone) graft group. Medical records and radiologic images of patients who underwent alveolar bone grafting due to alveolar cleft were analyzed retrospectively. Through postoperative and follow-up radiologic images, the height of the interdental bone septum was classified into four types based on the highest point of alveolar ridge. Then, the height of the interdental bone septum and the area of the bone graft were evaluated according to the type of bone graft. In addition, the occurrence of complications and the need for an additional bone graft, the result of postoperative orthodontic treatment, and the eruption of impacted teeth were investigated.ResultsThirty patients were included in this study. There was no significant difference in the change of the interdental bone height and the area of the bone graft according to the type of bone. There was no significant difference in the success rate of the surgery according to the type of bone. One patient underwent an additional bone graft surgery during the follow-up period.ConclusionsThe outcomes of alveolar bone grafting were not significantly different according to the type of bone graft. If appropriate to the size of the recipient site, the chin bone is a useful graft material in alveolar cleft, as is the iliac bone.

We evaluated and compared the outcomes of different ossification processes in patients with alveolar cleft in whom correction was performed using endochondral bone graft or intramembranous bone graft
We evaluated and compared the outcomes of the different types of ossification processes that were performed using endochondral bone grafting or intramembranous bone grafting in alveolar cleft patients
The patients were divided into groups by intramembranous bone graft and endochondral bone graft depending on the ossification of the grafted autogenous bone
Summary
We evaluated and compared the outcomes of different ossification processes in patients with alveolar cleft in whom correction was performed using endochondral bone graft or intramembranous bone graft. Cleft alveolus is a condition in which there is a break in the continuity of the alveolar process. Cleft alveolus is the anomaly resulting from the lack of fusion between the medial nasal process and the maxillary process, and it is usually associated with a cleft lip or palate or both [1]. Cleft alveolus is usually not addressed by the surgical correction of the cleft lip or cleft palate alone. After surgical repair of the cleft lip or cleft palate, the oronasal fistula should be closed and the continuity of the alveolar bone
