Bolton tooth size discrepancies among different malocclusion groups

ABSTRACT

One of the goals in comprehensive orthodontic treatment is to obtain an optimal final occlusion, overbite and overjet. It is the descriptive, cross sectional study conducted in orthodontic department of KMDC. Sampling methods was non probability convenient. Sample sizes were 55 patients. Age ranges between 12 to 23 years old. In the current study the men of anterior and overall ratio for class I malocclusion were similar to those of Bolton figures when comparing the mean tooth size ratio for these malocclusion group. It was found that class III> class II> class I for the overall anterior ratio. In the orthodontics treatment during diagnostics phase Bolton analysis should be used for the initial diagnostics and for treatment planning. In our study the mean and overall ratio for class I malocclusion similar to Bolton, no statistical difference were found among different malocclusion groups
