Abstract：Objective To investigate the suitable treatment methods of maxillary impacted canine of different status. Methods A retrospective study was done. Treatment records for 35 maxillary canine impacted cases treated of recently 10 years were analyzed .The treatment methods included helping eruption,surgically guided eruption and extraction. Re-sults There were 2 cases extracted and helping eruption in 16 cases. The waiting eruption time was 5-24 months. Good results were obtained in all cases except one 16-year old boy’s upper left canine pulp necrosis while erupting. Surgically guided eruption was done in 17 cases,and in 16 cases the impacted teeth were moved to the dental arch. Only one 21-year old patient,impacted canine was supposed partially ankylosed,the impacted tooth was moved slowly and the pa-tients refused to pull the tooth. Conclusion The teeth should be extracted it they are with severity deformity,curved short root,and are impacted in high position mesiodistally. When orthodontic expansion or extraction can achieve enough space for impacted canine and the canine can erupt spontaneously,helping eruption is preferred.When orthodontic treat-ment alone cannot remove the obstacle in the path of the canine eruption ,or ectopic canine presses to adjacent tooth root ,causing the root desorption,surgically guided eruption methods should be performed as quickly as possible. During surgically guided eruption,the direction and the force should be proper to avoid damage to gingiva.
