Evaluation in Arch Width Variations among Different Skeletal Patterns in District Solan Population

Abstract

Abstract Introduction The facial growth pattern differs from individual to individual, and the variations in it are quite high. The assessment of relationship of dental arch dimensions with the facial growth pattern is essential for proper diagnosis and treatment planning. Aim The purpose of this study was to evaluate and compare the dental and alveolar arch widths in patients with varying facial growth patterns in Distt. Solan population. Materials and Methods Pretreatment lateral cephalograms and dental study models of 45 patients with age group between 16 and 30 years were included in the study. Patients were divided into three groups: group I (normodivergent), group II (hypodivergent), and group III (hyperdivergent) on the basis of y-axis, Jarabak ratio, and SN-MP (Sella-Nasion–mandibular plane) angle. Interpremolar and intermolar dental and alveolar arch widths were measured and compared for all the three groups. Results The results showed that the dental and alveolar arch widths were increased in hypodivergent patients and decreased in hyperdivergent patients, which was not statistically significant. Conclusion It was concluded that the dental and alveolar arch dimensions increased as the facial pattern became horizontal.
