We encountered a case of inversely impacted tooth involving the left maxillary central incisor. Space was created in the position of the impacted tooth without extraction using the multi-bracket method and the tooth was exposed surgically. Because the tooth showed severe inverse impaction, we changed the bracket at the second fenestration and added traction to induce movement of the impacted tooth to the labial side. Thereafter, we achieved rearrangement with an arch wire and obtained occlusion. We used a removable retainer, but a relapse of the impacted tooth was observed due to the curved root, so we performed treatment once again and used a rigid retainer for the second retention. However, loss recurred and a third treatment was required. For the retainer, we use two types of removable retainer to prevent relapse.
