Maxillary incisor-based objectives in present-day orthodontics

Published:November 07, 2022DOI:https://doi.org/10.1053/j.sodo.2022.11.001

      ABSTRACT

      Orthodontists should be familiar in examining all the components of a smile. A parallel position of the facial aspect of the incisor crown to the face is considered to be the most aesthetic position of the maxillary incisor. A more anterior position of the maxillary central incisors has been shown to be more acceptable than a more posterior position. Exposition of the incisor should not be larger than 3 mm in relationship to the upper lip. The lack of objective criteria to position incisors may be a first step to make the patient become dissatisfied with the treatment result. This paper discusses the ideal buco-ligual inclination for maxillary central incisor, and their horizontal and vertical position. A simple way to determine a virtual goal for maxillary incisor position, using digital tools, will be explained as well as how to transfer the occlusal plane to 3d planning softwares. A clinical case is presented using the Glabellar vertical line, the Mid-forehead vertical line and the Functional Esthetical Oclusal Plane as tools to determine where the maxillary central incisors should be positioned for optimal esthetic results.
