Co-relation between Bolton ratio, anterior Bolton ratio and different vertical growth patterns

ABSTRACT

Bolton's method of diagnosing tooth size discrepancies has been widely used in scientific studies since its publication. Aim of this study was to calculate Bolton Ratio and Anterior Bolton Ratio[1, 2, 3] for patients with different Vertical Growth Patterns and establishing correlation between Bolton's anterior and overall ratios and vertical growth pattern assessment parameters. Study models and lateral Cephalogram were taken for 60 subjects selected on the basis of selection criteria and Bolton Ratio, Anterior Bolton Ratio, SNM, MMA, SNP, Y-axis, SOFA, Jaraback ratio and Facial Ratio were calculated and analyzed using SPSS version 10.Rresults concluded that 1. Bolton Ratio and Anterior Bolton Ratio though slightly different in Normal Angle, High Angle and Low Angle Cases but the difference was statistically insignificant and 2. Statistically insignificant correlation occurs between Bolton Ratio, Anterior Bolton Ratio and vertical growth pattern assessment parameters
