目的：应用美国ABO客观评分系统，对无托槽隐形矫治器和传统金属矫治器的矫治效果进行评价。方法选择120例成人轻中度错合畸形患者，分为无托槽隐形矫治器组和传统矫治器组各60例。用差异系数评价错合畸形严重程度， OGS评价治疗结果。结果无托槽隐形矫治器可以很好地矫治轻中度错合畸形，与传统金属托槽矫治器无统计学差异。结论无托槽隐形矫治器对轻中度错合畸形临床矫治效果可达到传统矫治器矫治的效果。

Objective The aim of this study is to assessment treatment -outcome of invisalign treatment compared with braces by ABO .Methods This retrospective study select 2 groups of 120 patients ( invisalign and braces groups including both 60 patients ) were evaluated by using methods from the American Board of Orthodontics .The discrepancy index was used to analyze pretreatment records to control for initial severity of malocclusion . The objective grading system ( OGS ) was used to systematically grade posttreatment records .Statistical analyses evaluated treatment outcome of invisalign compared with braces .Results The invisalign group significant improve results and was no difference between both groups .Conclusions According to the OGS , invisalign treat malocclusions as well as braces in this sample .
