The purpose of this article is to report the management of a transmigrated mandibular canine with emphasis on saving the tooth as natural part rather than surgical removal of the transmigrated tooth. There are several treatment options proposed for impacted mandibular canines including surgical removal, exposure and orthodontic alignment, intra-alveolar tooth transplantation (surgical repositioning of a tooth in its alveolar socket) and observation. The technique, surgical repositioning of a tooth involves the surgical extraction of impacted tooth and fixation in the correct position in the dental arch after surgical preparation (correction) of the alveolar socket. It is especially valuable in cases of difficult-to-treat impaction. A repositioned tooth is better substitute than fixed or removable prostheses, and the technique is more cost effective than other methods. Patients with excellent oral hygiene should be considered as preferred candidates for surgical repositioning of tooth. Disadvantages include the invasiveness of surgery, the difficulty of projecting long term stability due to chances of root resorption and loss of gingival attachment.
本文的目的是报告一颗移位下颌尖牙的处理方法,重点是将该牙作为天然牙体保留下来,而非手术拔除移位牙。对于阻生下颌尖牙,有多种治疗方案可供选择,包括手术拔除、暴露并正畸排齐、牙槽内牙齿移植(将牙齿手术复位至牙槽窝内)以及观察。牙齿手术复位技术包括手术拔除阻生牙,并在牙槽窝手术预备(矫正)后将其固定于牙弓中的正确位置。该技术在治疗难度较大的阻生情况时尤为有价值。复位后的牙齿比固定或可摘义齿更优,且该技术比其他方法更具成本效益。口腔卫生良好的患者应被视为牙齿手术复位的首选对象。其缺点包括手术的侵入性、由于牙根吸收和牙龈附着丧失的可能性而难以预测长期稳定性。
