Smart Brackets for 3D-Force-Moment Measurements in Orthodontic Research and Therapy – Developmental Status and Prospects*

摘要

Background and Aim: Quantitative knowledge of the three-dimensional (3D) force-moment systems applied for therapeutic tooth movement is of utmost importance, with regard to the predictability of the course of tooth movement, as well as the reduction of traumatic side effects. The concept of a smart bracket with an integrated sensor system for 3D force and moment measurement has recently been published. The feasibility of this approach has been demonstrated using finite-element (FE) simulations and a 2.5 times enlarged real smart bracket model. The aim of this study was to develop and to mechanically characterize the first wire-mediated, true-scale smart bracket.
