Experimental determination of optimal force system required for control of anterior tooth movement in sliding mechanics.

INTRODUCTION This study was designed to determine the optimum vertical height of the retraction force on the power arm that is required for efficient anterior tooth retraction during space closure with sliding mechanics. METHODS Three adults (1 man, 2 women) with Angle Class II Division 1 malocclusions were selected for this study. In each subject, the… (More)
