Objective To analyze the characteristics of alveolar bone height changes in anterior teeth before and after orthodontic treatment for Class Ⅱ Class 1 malocclusion. Methods 73 patients who were treated in our hospital from January 2017 to January 2018 were randomly divided into observation group(37 cases) and control group(36 cases). Results The alveolar bone of the two groups were compared after treatment. The changes of the labial height of maxillary central incisor and maxillary canine in the observation group were compared with those in the control group(P < 0.05).At the same time, the appearance changes of the two groups also showed data difference(P < 0.05). Conclusion Stealth correction and fixed correction can achieve certain results in the treatment of Class Ⅱ Class 1 malocclusion, but by contrast, the effect of stealth correction is more ideal, so it should be the preferred method of clinical treatment.
