摘要


牙冠牙根斷裂之處理,由於同時牽涉到牙髓病科、牙周病科及贗復牙科等多科,如何重建該斷裂牙齒之功能及美觀,是件充滿挑戰性的工作。本報告藉由將一顆牙冠牙根斷裂的上顎側門牙拔出旋轉180度再植入。希望能提供相似病例一個另外的處理方式。

The treatment of complicated crown-root fracture is a challenge to dentists. Complicated crown-root fracture involving enamel, dentin & pulp that extend below both the gingival margin & the alveolar bone is difficult to restore. Invading the biologic width sets up a series of events through an inflammatory process that can lead to pocketing around the tooth by the body’s attempt to re-create this “width” through alveolar bone less. Therefore the treatment protocol is to expose the fracture line & to maintain the biologic width. There are various treatment options in management of complicated crown-root fracture, including crown lengthening, orthodontic extrusion, surgical extrusion & extraction. This case report describes an alternative treatment option, the intentionally rotated replantation, in management of an upper lateral incisor with complicated crown-root fracture.
