The Gable bend revisited.
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.
