The author presents the advantages and the drawbacks of two systems of lingual brackets positioning which allows to obtain a very good finish of the treatments. The Class System is a protocol made from a Set-Up but which does not allow the bonding of the teeth with unfilled resins. The other system uses the T.A.R.G. with the Thicknesses Measure Appliance and the Ideal Drawing of Lingual Arch program; it allows to program the torque, the angulations, the heights and the thicknesses (from the bottom of the throat to the vestibular side) of each tooth.
作者介绍了两种舌侧托槽定位系统的优缺点，这两种系统都能使治疗取得很好的效果。Class系统是一种基于排牙完成的方案，但不允许使用未填充树脂粘结牙齿。另一种系统使用带厚度测量装置的T.A.R.G.和舌弓理想绘图程序；它可以对每颗牙齿的扭矩、角度、高度和厚度（从龈方底部到前庭侧）进行编程。
