Abstract:
Background Smile analysis is part of a facial analysis and allows dentists to recognize positive and negative elements in each patient's smile. Depending on the type of malocclusion, facial pattern of the patient and mechanics adopted, orthodontic treatment can prove either beneficial or harmful to smile esthetics. Thus, it is reasonable to regard smile analysis as an important tool for diagnosis and orthodontic treatment planning. The purpose of this study was to evaluate the Analysing smile arc to determine the degree of improvement in the smile and incisal exposure after orthodontic treatment of patients with Class II malocclusion.The aim of this study is to analyse the smile arc and incisor exposure in class 2 patients before and after orthodontic treatment. Materials and methods Frontal photographs were taken both before and after orthodontic treatment. Landmarks were placed on each tracing made from the photograph. Thereafter, landmarks were digitised into an x and y coordinates system. The Class II pretreatment and post-treatment groups of smile arc and incisor exposure conditions were compared using fishers chi square test. Result The overall analysis of the study indicates that there are improvements in features of the smile arc and incisor exposure of the patients who have undergone treatment for Class II malocclusion. Even after treatment, the Class II subjects showed a difference from the control subjects regarding their smile arc.The coordinates of the class II pretreatment group and post treatment group in smiling conditions, clear significant (P<.05) differences in vertical axis. Conclusion Orthodontic treatment induced larger amount of lip movement change during smiling ,which may reflect the esthetic and emotional changes in the patients after treatment.
