全景片和锥形束CT评价牙根近远中倾斜度的现状和进展

Current situation and progress of evaluating mesiodistal root angulation by panoramic radiography and cone beam computed tomography

正畸综合治疗的基本目标之一是将牙齿定位于正确的三维空间位置,合适的牙根近远中倾斜度是其要求之一。现有临床评估牙根近远中倾斜度的方法主要有全景片和锥形束CT(CBCT),两者效能不同,各有优缺点。本文就全景片和CBCT用于评价牙根近远中倾斜度的现况和进展进行综述。

A fundamental goal in comprehensive orthodontic treatment is the correct angulation of all teeth in three pranes of space, and this calls for proper mesiodistal root angulation. Nowadays the main available methods to evaluate mesiodistal root angulation are panoramic radiography and cone beam computed tomography （CBCT）. Each one of them has its own benefit and limitation with different efficacy. This article is to review the current situation and progress of these two methods in evaluating mesiodistal root angulation.
