[Correction of dento-maxillofacial deformities by using both of orthodontics and orthognathic surgery].

OBJECTIVE: To study the clinical results and stability after correction of dento-maxillofacial deformities by using both of orthodontics and orthognathic surgery. METHODS: A group of 45 patients with dento-maxillofacial deformities were corrected by preoperative orthodontics-orthognathic surgery-postoperative orthodontics procedure. As a control, another group of 64 patients with the deformities were corrected by orthognathic surgery only. The facial appearance, occlusion and stability of two groups after correction were investigated and compared. RESULTS: In orthodontics and orthognathic surgery group, 62.2% of patients declared that their mastication were improved. Relapse rate of deformities was 4.4%. In orthognathic surgery group, 42.2% of patients declared that their mastication were improved. Relapse rate of deformities was 9.4%. CONCLUSIONS: Using both of orthodontics and orthognathic surgery to correct dento-maxillofacial deformities is a good approach to improve results of correction, keep balance of occlusion and reduce the relapse of the deformities.
