A 12-year-old Japanese boy had ectopic eruption of the permanent maxillary canines and permanent mandibular second molars accompanied by root resorption of the adjacent permanent teeth. The permanent maxillary lateral incisors were extracted, and fenestration traction treatment was performed for the ectopically erupting canines. They were moved to the occlusal position orthodontically using a lingual arch appliance and sectional arch wire. The mandibular second molars were moved distally with an appliance designed to minimize the load on the teeth. The treatment is discussed with consideration of the diagnosis and appliances.
一名12岁的日本男孩上颌恒尖牙和下颌恒第二磨牙异位萌出,并伴有相邻恒牙的牙根吸收。拔除了上颌恒侧切牙,并对异位萌出的尖牙进行开窗牵引治疗。使用舌弓矫治器和片段弓丝将它们正畸移动到咬合位置。使用一种旨在最小化牙齿负荷的矫治器将下颌第二磨牙向远中移动。结合诊断和矫治器对该治疗进行了讨论。
