Abstract：Objective To study the influencing factors of successful closed traction for maxillary impacted canine,and to further know the difficulty of the traction of impacted teeth,and then to guide the clinical treatment plan.Methods Collect the clinical cases of impacted teeth from the year 2007 to 2016 in China Medical University Stomatology Hospital,and calculate the success rate of different impacted teeth.Measure angulation with palatal plane,positions with lateral incisors and buccal-lingual direction of maxillary impacted canine.The age of patients was also recorded at the same time.The data were analyzed statistically by SPSS 21.0 statistical software.Results Chi-square test suggested that the age of the patient,buccal-lingual direction and the angulation affected the traction of maxillary impacted canine,but the relative position with the lateral incisor didn't.Additionally,only the buccal-lingual direction of maxillary impacted canine affected the traction by logistic regression analysis.Conclusion The buccal-lingual direction of maxillary impacted canine is the main factor that affects the success of traction,which is to say that buccal impacted maxillary canine is more likely to have successful traction.
