電腦斷層攝影在診斷上顎前牙區阻生齒之運用

The Application of Computerized Tomography Images in Diagnosis of Maxillary Anterior Impacted Teeth

摘要


利用傳統X光影像來診斷上顎前牙區阻生齒有一定的限制,本研究內容在於使用電腦斷層數位影像來提昇治療前阻生齒形態與精確位置定位評估的準確性。藉由兩個上顎前牙阻生齒臨床病例,探討透過電腦斷層數位影像得到傳統影像所無法提供的資訊,特別在阻生齒形態異常或與相鄰組識構造有較複雜空間關係時,可獲得較精準的鑑別診斷,並影響阻生齒治療計畫的訂定。

The purpose of this study is to propose the use of computerized tomography to enhance accuracy of localizing impacted tooth and assessment tooth morphology before treatment because using traditional X-ray images to diagnose maxillary anterior impacted teeth has its limitations. Two clinical cases of maxillary anterior impacted tooth were presented to show that computerized tomography digital images provided information which traditional images were unable to provide, especially in cases of the impacted tooth with abnormal morphology or complex spatial relations with adjacent structures. Computerized tomography digital images facilitate more accurate differential diagnosis, and influence the treatment plannings of impacted tooth.
