Preferred Occlusal Cant for Patients with Orbital Dystopia
Abstract
Purpose: The purpose of this study is to evaluate the preferred frontal occlusal cant for patients with orbital dystopia from the perspective of the layperson and dental professional. Methods: Frontal smiling photographs of three subjects of different ethnicities were digitally altered to simulate orbital dystopia by tilting the interpupillary line either 4 degrees clockwise or counterclockwise. The occlusal plane was subsequently altered four times to produce four varying degrees of a frontal occlusal cant: matching the degree of simulated orbital dystopia (defined as a 0 degrees difference), 2 degrees less than the degree of simulated orbital dystopia (2 degrees difference), parallel to the horizon (4 degrees difference), and 2 degrees past the horizon in the opposite direction of the simulated orbital dystopia (6 degrees difference). These four images were displayed side-by-side on a single sheet of paper and were rated according to perceived attractiveness on a 50mm VAS (visual analogue scale) by 50 laypeople and 50 dental professionals; 100 questionnaires were distributed in total. Non-normally distributed data were presented as median and interquartile range (IQR) and were analyzed using Wilcoxon's signed ranks test (non-parametric paired t-test), Mann-Whitney test (nonparametric independent t-test) or Friedman's rank test (non-parametric repeated measures analysis of variance) where appropriate. Results: Dental professionals and laypeople preferred frontal occlusal planes parallel to the true horizon and rated an occlusal plane parallel to the orbital dystopia as least attractive.
