ABSTRACT
Objective To evaluate the orthodontic effect of surgery on mixed dentition period class Ⅲ malocclusion and to investigate the effective therapeutic method of the skeletal class Ⅲ malocclusion.Methods A total of 20 patients aged 8.5 to 9.1 years with early mixed dentition class Ⅲ skeletal malocclusion.The treatment was divided into two phases.During the first phase,the entire stuffy group was treated with a bonded maxillary expansion and protraction.During the second phase,the entire study group received multiple loop edgewise arch wire (MEAW) treatment until an ideal occlusion relationship achieved.Comparison of the pre-and post-orthodontic treatment cephalometric radiographs had been done after maxillary protraction and MEAW were applied for patients.Results In the 20 patients after orthodontic treatment,Class Ⅲ skeletal facial profile was improved,the retraction of anterior teeth was obvious,and there were significant changes in dentition; the profile of soft tissue and satisfactory occlusion relationship were significantly improved,as compared with the changes between pre-treatment and post-treatment.Conclusions Skeletal Ⅲ malocclusion in early mixed dentition can be successfully treated.The results can be satisfied with improved class Ⅲ skeletal and molar relationship,high-angle and profile of soft tissue.
