Ectopic eruption and impaction of canines is a frequently encountered clinical problem. The incidence of impaction ranges between 1% and 3%. The cause of canine impaction can be the result of localized factor(s) or can be a polygenic multifactorial inheritance and associated with other dental anomalies. There are a number of possible sequelae to canine impactions, ranging from loss of space in the arch to resorption of the roots of the neighboring teeth. Although the management of the ectopically erupting teeth necessitates the combined expertise of a number of clinicians, the orthodontist should have the primary responsibility of coordinating these efforts to provide the patient with the optimal treatment options with the most stable and favorable outcome.
犬齿异位萌出和阻生是临床常见问题。阻生发生率在1%至3%之间。犬齿阻生的原因可能是局部因素，也可能是多基因多因素遗传，并与其他牙齿异常有关。犬齿阻生有许多可能的后遗症，从牙弓间隙丧失到邻牙牙根吸收。虽然处理异位萌出的牙齿需要多位临床医生的综合专业知识，但正畸医生应主要负责协调这些工作，为患者提供最稳定、最有利的最佳治疗方案。
