Generating an Ideal Virtual Setup with Three-Dimensional Crowns and Roots
Volume 49 : Number 11 : Page 696 : Nov 2015
The goal of orthodontic treatment is to move teeth from malocclusion to a functional, esthetic, and stable ideal occlusion in which all dental crowns and roots are in the correct three-dimensional positions. Mesiodistal, labiolingual, and occlusogingival positions and axial rotations can be determined solely from the crowns of the teeth, but mesiodistal angulations and faciolingual inclinations may be better assessed by viewing both the crowns and roots. Although most of the focus in orthodontic treatment is on crown positions as determinants of esthetic appearance and occlusal contacts, improper root positions may increase the risk of relapse, periodontal damage, and undesirable tooth movements under occlusal loads.
