Canine impaction is a dental problem very often encountered in orthodontic practice. After the third molar, the canine is the most frequently impacted tooth. Bringing the impacted canine into a normal position is important for functional occlusion and the final esthetics of the orthodontic treatment. This article illustrates a peculiar case, in which all four permanent canines maintained their unerupted status at age of 16 years. All four impacted canines were surgically exposed, attachment bonded, traction given with K-9 spring and ideally positioned with fixed orthodontic mechanotherapy.
犬牙阻生是正畸临床中经常遇到的牙齿问题。在第三磨牙之后,犬牙是最常发生阻生的牙齿。将阻生犬牙牵引至正常位置对于功能性咬合及正畸治疗的最终美观效果都很重要。本文阐述了一个特殊病例,一名16岁患者的四颗恒牙犬牙均处于未萌出状态。四颗阻生犬牙均通过外科手术暴露、粘接附件,使用K-9弹簧进行牵引,并通过固定正畸机械疗法将其理想定位。
