Abstract

This chapter reviews T-Scan use in Orthodontics, defines normal T-Scan recordings for orthodontically treated subjects versus untreated subjects, and explains T-Scan use in the case-finishing process. After orthodontic appliance removal changes in the occlusion result from “settling,” because teeth can move freely within the periodontium. Despite a post treatment, visually “perfect” Angle's Class I relationship, ideal occlusal contacts often do not result solely from tooth movement. Creating simultaneous and equal contacts following fixed appliance removal can be accomplished using T-Scan data to optimize the end-result occlusal contact pattern. The software's force distribution and timing indicators (the 2 and 3-Dimensional ForceViews, force percentage per tooth and arch half, the Center of Force, and the Occlusion and Disclusion Times) aid in obtaining an ideal occlusal force distribution during case-finishing. Several case reports highlight combining lingual orthodontic treatment with Orthognathic surgery, where each presented case utilized T-Scan data during active treatment and retention.
