This case report describes the management of a patient who presented with an interdental eyelet-style retainer placed around maxillary central incisors ten years ago. At that time, the patient underwent orthodontic treatment to close a large maxillary midline diastema. The maxillary central incisors were then crowned to close the small residual midline diastema remaining after the orthodontic treatment. The wire retainer was apparently placed to prevent the diastema from reopening. The patient sought treatment ten years later when pain from necrotic pulps in these central incisors became unbearable.
本病例报告描述了一名患者的治疗情况。该患者十年前在上颌中切牙周围放置了牙间孔眼式保持器。当时，患者接受了正畸治疗以关闭上颌较大的中线间隙。随后对上颌中切牙进行了牙冠修复，以关闭正畸治疗后残留的小中线间隙。显然放置钢丝保持器是为了防止间隙重新出现。十年后，当这些中切牙牙髓坏死引起的疼痛变得难以忍受时，患者寻求治疗。
