This manuscript describes the use of a tooth indicated for extraction due to orthodontic reasons as an anchorage aid to receive undesirable side effects caused by orthodontic uprighting of a contralateral molar tooth. The mandibular right second molar was mesially tipped as a result of loss of the adjacent first molar. Since the treatment plan involved extraction of the mandibular left first premolar, undesirable side effects associated with the molar uprighting movement were transferred to this tooth. Once the second molar was vertical, the premolar was extracted and the treatment continued. The results suggest that treatment time can be reduced if undesirable orthodontic mechanical side effects can be directed to a tooth whose extraction is indicated.
本手稿描述了将一颗因正畸原因而需拔除的牙齿用作支抗辅助装置，以承受对侧磨牙正畸直立所产生的不良副作用。下颌右侧第二磨牙因相邻第一磨牙缺失而向近中倾斜。由于治疗计划包括拔除下颌左侧第一前磨牙，与磨牙直立移动相关的不良副作用转移到了这颗牙齿上。一旦第二磨牙直立，就拔除前磨牙并继续治疗。结果表明，如果能将不良正畸机械副作用导向一颗已确定需拔除的牙齿，治疗时间可以缩短。
