Angular asymmetries of the human face.

摘要: PURPOSE The determination of an acceptable occlusal plane is essential for the development esthetic prosthodontic restorations. However, since most faces are not symmetric, a method was developed measuring facial angular asymmetry, i.e., divergence from vertical or horizontal line joining midpoint intercanthal and philtrum lip, interpupillary line, intermeatal lip commissure intercuspid line. MATERIALS AND METHODS Standardized frontal images (mouth closed, smiling, biting on wooden spatula) 100 subjects were taken using digital camera. These downloaded into computer, angles between various lines measured. grouped by sex, age, history trauma orthodontic treatment. RESULTS No statistically significant differences found mean values each group. CONCLUSION Asymmetry face can be measured camera imaging computer analysis. A range asymmetries that influence choice during treatment exists. Thus, use parallel to ala tragus lines, as often advocated prosthodontists, may result in less than ideal esthetics final restoration.
