Replantation of avulsed teeth using the 180-degree rotation method and a vacuum-formed splint in mixed dentition: a case report

抄録

It is often very difficult to replant avulsed teeth in the deciduous and mixed dentition when the cortical bone is fractured and there are no adjacent teeth for anchorage. In this article, we describe the management of avulsed maxillary incisors in a 7-year-old boy. The avulsed teeth could be successfully repositioned by intra-alveolar transplantation using the 180° rotation (buccolingual reverse) method, which was originally applied to preserve teeth with relatively deep subgingival crown-root fracture, and a vacuum-formed splint was used for fixation. The avulsed teeth were followed up for 42 months. The post-operative course was uneventful with an aesthetic and functionally stable outcome. (J Oral Sci 56, 231-234, 2014)
