摘　　要：上颌尖牙是除第三磨牙外最易阻生的恒牙,患病率为1%-3%。上颌尖牙阻生会导致邻牙牙根松动、错合畸形、含牙囊肿等并发症,其治疗难度大、治疗周期长、费用高,有治疗失败、牙周损害等风险。通过早期预测,有利于早期发现和及时采取阻断性治疗。上颌尖牙阻生的阻断治疗方法包括拔除乳尖牙、头帽颈牵引、早期上颌扩弓等,可在不同程度上提高上颌尖牙的自发萌出率,避免复杂的正畸综合治疗,节约治疗时间和费用。本文通过文献回顾,来总结上颌阻生尖牙的早期预测和阻断治疗方法的研究进展,希望能为早发现、早诊断、早治疗上颌尖牙阻生提供参考。Maxillary canine is one of the most frequently impacted teeth,second only to third molars with the prevalence ranging from 1 to 3 percent.The complications of Impacted maxillary canine include adjacent tooth root loosening,malocclusion and dental cysts.The treatment is difficult with a long period and high cost.Moreover,there are risks of treatment failure and periodontal damage.Early prediction of impacted maxillary canine is conducive to early detection and timely treatment.Interceptive approaches include extraction of primary canine,headgear treatment and maxillary expansion,which can improve the spontaneous eruption rate of maxillary fangs to varying degrees,avoid complex comprehensive orthodontic treatment,and save treatment time and cost.Based on the literature review,the paper summarizes the research progress of early prediction and Interceptive approaches of maxillary impacted canines,hoping to provide references for early detection,diagnosis and treatment of maxillary impacted canines.
