Gable bends are frequently incorporated into a variety of loop configurations to provide appropriate moment-to-force (M/F) ratios in the controlled closure of space between individual teeth or groups of teeth. Appropriate magnitudes and occlusogingival locations of the Gable bends are shown to be vital to maintain the neutral position of the closing loop. Otherwise, the clinician has no meaningful reference point from which to judge the spring's activation to obtain the force aspect in the M/F ratio. A simple means of preserving the neutral position is shown, with the vertical loop as an example that can be applied to many common loop configurations.
三角弯通常被纳入各种曲的构型中，以便在单个牙齿或牙齿组之间的间隙受控关闭时提供合适的力矩与力（M/F）比。结果表明，三角弯的合适大小和咬合龈向位置对于维持关闭曲的中性位置至关重要。否则，临床医生就没有有意义的参考点来判断弹簧的激活情况，从而在M/F比中获得力的方面。本文展示了一种保持中性位置的简单方法，以垂直曲为例，该方法可应用于许多常见的曲构型。
