Miniscrew-supported coil spring for molar uprighting: Description

Abstract

Introduction: Since the beginning of miniscrews as orthodontic anchorage, many applications have been described in the literature. Among these, one is the uprighting of mesially inclined molars. In regard to the mechanical aspects, however, there is little information about the application of orthodontic forces using such devices. Objective: The objective of this study was to describe a miniscrew supported spring for uprighting of mesially inclined molars. With this device, one can achieve the correct use of rthodontic biomechanics, thus favoring more predictable tooth movements and preventing unwanted movements from occurring. © 2013 Dental Press Journal of Orthodontics.
