摘要

在兒童及青少年時期，因齒瘤而阻礙恆門牙之萌發，雖偶爾發現但不容易處理。早期診斷及適切治療對兒童及青少年的發展相當重要。本報告之病例即為藉由牙科放射檢查診斷出混合性齒瘤及阻生側門齒。在全身麻醉狀態下將齒瘤剜出，並於阻生側門齒裝置舌側鈕及結紮線。藉著覆蓋性萌發術及持續且輕的矯正拉出治療，將上顎阻生左側門齒成功地牽引至適當的位置。隨後，上下顎齒列再經由細至粗的矯正線，循序漸進地將之排列整齊，達到正常咬合。在兒童及青少年時期，藉由臨床口腔檢查及放射照相方式，對任何延遲萌出的恆齒作早期診斷且適切的治療，可以確保較佳之治療結果。

Interference with the eruption of impacted permanent incisors by odontoma is occasionally detected but difficult to manage in children and adolescents. Early diagnoses and successful treatment are important to developing youngsters. In this article, a compound odontoma and an impacted lateral incisor were diagnosed by radiographs. Odontoma was enucleated surgically and the impacted maxillary lateral incisor was bonded with a lingual button and attached with a traction hook under general anesthesia. By closed eruption and light force orthodontic traction techniques, the impacted maxillary left lateral incisor was successfully positioned into proper occlusion. The final occlusion was completed by full strap-up of both arches with light and heavy wires sequentially. Early diagnoses of any delayed eruption of permanent dentition by radiographic examination and proper treatment ensure better results for children and adolescents.
