Abstract
The purpose of this study was to determine the correlation between the anteroposterior position of the lips against changes in the length and width of the dental arch in Class I malocclusion non extraction. The sample was 30 patients PPDGS Orthodontic clinic of FKG USU. The sample used was 30 before treatment study models, 30 after treatment study models, 30 before treatment lateral cephalometric photograph, and 30 after treatment lateral cephalometric photograph. The study was conducted by measuring the width of interpremolar, intermolar and arch length of study models and the position of the upper lip and lower lip to e-line of lateral cephalometric photograph. The data was processed with SPSS and data normality was tested by Mann Whitney test. There is no correlation statistically between the before and after treatment of anteroposterior lip position against changes in the length and width of the dental arch before and after treatment. There is no correlation between the anteroposterior lip position against changes in the length and width of the dental arch in Class I malocclusion non extraction.
