摘要: 牙齿近远中倾斜度是指牙体长轴与牙合平面垂线所成的角度,作为评价正畸治疗的指标之一,正畸医生需要对其在治疗前后密切关注。临床上现有评价牙齿近远中倾斜度的影像学方法主要包括曲面断层测量与锥形束CT(conebeam computed tomography, CBCT)测量,两者各有其特点。本文就近年来曲面断层与CBCT测量牙齿近远中倾斜度的方法及其各自准确性进行综述。

Abstract: As one of the targets of orthodontic treatment, orthodontists need to pay close attention to the tooth mesiodistal angulation which refers to the angulation between the long axis of the tooth and the vertical line of the occlusal plane before or after treatment. Nowadays, major clinical methods of measuring mesiodistal angulation include panoramic radiography and conebeam computed tomography (CBCT), which have different characteristics. This article is to review the progress of these two methods of evaluating tooth mesiodistal angulation and their accuracy.

Key words: tooth mesiodistal angulation, panoramic radiography, cone-beam computed tomography
