[Correction of dento-maxillofacial deformities by using both of orthodontics and orthognathic surgery]
1Department of Oral Maxillofacial Surgery, School of Stomatology, Sun Yet-sen University of Medical Sciences, Guangzhou 510060, China.
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.
