ABSTRACT: This article reports a case in which a horizontally impacted wisdom tooth was orthodontically uprighted to replace a missing molar. Through mandibular single-arch treatment utilizing a long-arm buccal tube, uprighting auxiliary spring, and miniscrew implant, the impacted wisdom tooth was successfully uprighted and mesialized to substitute for the missing molar, effectively restoring occlusal function in the edentulous area. Written informed consent was obtained from the patient, and the treatment protocol was approved by the institutional ethics committee.
