中文摘要 | 多生牙是最常造成上顎正中門齒阻生的原因,而阻生門齒的處理經常需要接受埋伏齒露出及矯正治療,對於早期混和齒列,未萌發的門齒接受矯正治療時要得到良好的錨定是很大的挑戰,且對於兒童患者,病人的合作度及口腔衛生的維持都會影響治療的結果,因此在這個階 段,使用改良式南西式裝置(Modified Nance Appliance)是可替代的治療方式。本案例報告是一位8歲男童,因多生牙造成兩顆上顎正中門齒阻生,移除多生牙後接受上顎正中門齒埋伏齒露出後,利用改良式南西式裝置將阻生齒拉出,四個月的治療後,兩顆阻生門齒皆移到適當的位置,且牙髓神經仍具有活性,對敲診及敏感度測試皆正常,X光片顯示牙根持續正常生長且牙周狀況正常。 |
英文摘要 | The presence of supernumerary teeth often cause impaction of maxillary central incisors. The major treatment procedure for an impacted tooth is orthodontic traction after proper crown exposure surgery. One of the challenges of orthodontic treatment for unerupted central incisors in the early mixed dentition is to get enough anchorage for tooth retraction. Furthermore, the compliance of the patient and maintenance of the oral hygiene are also problems for early ortho treatment. Therefore, the banded appliance is an alternative method for impacted incisor correction. This article shows a case of an 8-year-old boy with two unerupted maxillary central incisors and a supernumerary tooth. After removal of the supernumerary tooth and surgically exposure of the central incisors, the patient's old banded kiddy denture was modified to an orthodontic appliance for retraction the incisors. Four months after light force orthodontic treatment, both the impacted incisors moved into proper position. And the erupted incisors remain vital, responding normally to percussion and sensitivity test clinically; Both teeth show continuous root formation and have normal periodontal health on the four months follow-up radiographs. |
