扩张是一种牙齿畸形，其特征是牙冠和牙根之间的成角导致牙齿无法萌出。它通常发生在乳牙列创伤后，乳牙列的顶端靠近恒牙芽。对于严重撕裂牙，手术拔牙是首选的治疗方法。在本病例报告中，描述了如何通过适当的手术和正畸管理，避免使用假体/植入装置，成功将一名年轻患者的撕裂中门牙移动到对齐位置。将创伤后的全景X线片与治疗结束时的全景X线片进行比较。结果是可持续的长期牙周和美学方面。
Dilaceration is a dental deformity characterized by an angulation between crown and root causing non-eruption of the tooth. It generally occurs following trauma to the deciduous dentition the apices of which lie close to the permanent tooth buds. Surgical extraction used to be the first choice in treating the severely dilacerated teeth. In this case report, it is described how a dilacerated central incisor was successfully moved into alignment in a young patient with proper surgical and orthodontic management avoiding use of prosthetic/implant devices. The panoramic radiograph after the traumatic injury is compared with the one at the end of treatment. The results were sustainable over long-term in both periodontal and aesthetic terms.
