Abstract: Objective:To evaluate the profile esthetics of children with skeletal class Ⅲ malocclusion treated with micro-implant.Methods:20 patients (12 boys and 8girls) aged 11-13 years were treated by micro-implant and maxillary protraction for 8 to 10 months.The profile esthetic indexes were measured on pre-and post-treatment cephalometric radiography.Results:The esthetic of the patients were remarkably improved after treatment.The factors that influence the esthetic index of children were the anteroposterior relationship of the maxilla,the mandible and the thickness of soft tissue.The results were stable 1 year after treatment.Conclusion:Maxillary protraction by micro-implant can improve the profile esthetic of children with Class Ⅲ malocclusion,correct over-bite and over-jet.
