Perception Of Profile Appearance As Judged By Peers Using 3d Video Imaging, Megan G. Schuler
Perception Of Profile Appearance As Judged By Peers Using 3d Video Imaging, Megan G. Schuler
Theses and Dissertations
The purpose of this study was to investigate the social perceptions of subjects with differing lip position and facial convexity in three dimensions. A 3dMD camera (3dMD, Atlanta, GA) was used to capture 3D images of 9 subjects’ faces. The images were altered to have ideal lip position and ideal convexity, ideal lip position and Class II convexity, Class II lip position and ideal convexity, and Class II lip position and Class II convexity. 400 laypersons rated their perceptions of the subjects’ athletic ability, popularity, leadership, and intelligence on a VAS scale. Subjects with ideal lip position relative to the …
Mandibular Incisor Proclination Variability During Class Ii Correction, James Redford
Mandibular Incisor Proclination Variability During Class Ii Correction, James Redford
Theses and Dissertations
Background: Lower incisor proclination has been shown to increase during Class II correction with appliances such as the Forsus. This lower incisor flaring shows great variability among patients. The purpose of this study was to evaluate the effects of Class II severity, mandibular growth, and occlusal plane rotation on lower incisor flaring in patients treated with the Forsus appliance. Materials and Methods: 121 records of Class II patients treated with the Forsus appliance were analyzed retrospectively. Cephalograms were traced at three time points. ANOVA was used to compare changes in cephalometric measurements over time. Pearson’s correlation was used to test …
Compliance-Free Class Ii Correction And Its Relationship To Vertical Facial Characteristics, Michael Shoff
Compliance-Free Class Ii Correction And Its Relationship To Vertical Facial Characteristics, Michael Shoff
Theses and Dissertations
Background: While efficacy of the Forsus appliance has been shown, there are disagreements on its mechanism for Class II correction. Class II studies have been criticized for ignoring potential differences in results based on differing vertical facial phenotypes. The purpose of this study was to better understand the effects of Class II correction using the Forsus appliance and relate changes during and at the completion of treatment to initial MP-SN angles. Materials and Methods: Records of 59 patients obtained at 4 different time points were examined retrospectively. ANOVA was used to describe the cephalometric changes and Pearson’s correlation tested for …
