This case report describes an unusual phenomenon related to bilaterally displaced canines, where both upper lateral incisors were absent, but where the canines produced extensive root resorption of both upper first premolars, necessitating their removal.
本病例报告描述了一种与双侧异位尖牙相关的不寻常现象，即双侧上颌侧切牙缺失，但尖牙导致双侧上颌第一前磨牙广泛的牙根吸收，因此需要拔除。
