Maxillary Arch Width And Buccal Corridor Width And Area Changes In Class I Extraction Cases.
Journal Title: International Journal of Dental Science and Innovative Research (IJDSIR) - Year 2019, Vol 2, Issue 2
Abstract
Aims and Objectives: To compare the pre-treatment and post-treatment maxillary arch width and buccal corridor changes in class I malocclusion treated with four premolar extraction Methods: pretreatment and post treatment study cast models and frontal smiling photograph of 80 patients with class I malocclusion of age group of 13-30yrs (21 male ,59 female) were analyzed Statistical analysis: Analysis was done using SPSS version 20 (IBM SPSS Statistics Inc., Chicago, Illinois, USA) Windows software program. Descriptive statistics included computation of means and standard deviations. The independent t test (for quantitative data within two groups) and paired t test (for quantitative data to compare before and after observations) were used for quantitative data comparison of all clinical indicators. Level of significance was set at P≤0.05. Results: There were insignificant changes in the anterior arch width in relation to anterior rugae and significant increase in the posterior arch width in relation to third, lateral and medial rugae. There was no significant difference between pretreatment and post treatment buccal corridor width and area. Conclusions: The results indicate that the arch width is not decreased at the constant arch depth because of the extraction of premolars in class I malocclusion.
