摘要：

正畸治疗的目的是通过改变牙齿整体的三维位置从而获得相对正常的咬合关系，因而正常牙合是诊断和治疗错牙合畸形的基础与标准。牙齿近远中倾斜度是正常牙合重要组成因素之一，目前测量牙齿近远中倾斜度的方法各有千秋。本文就各种测量牙齿近远中倾斜度的方法做一综述。

Abstract:

The basic objective of orthodontic treatment is to obtain the near-normal occlusion by correcting tooth positions in 3-dimentional space，and one of the keys to ideally positioned teeth is proper mesiodistal angulation. There are different kinds of available methods to measure the tooth mesiodistal angulation nowadays. This article is to review the research progress in measuring methods of tooth mesiodistal angulation.

Key words: mesiodistal angulation；coordinate measuring machine；panoramic radiography；cone-beam computed tomography, CBCT
