Comprehensive intermaxillary tooth width proportion of Bangkok residents.
Proper occlusion depends on the correct width ratio between upper and lower teeth, known as Bolton's ratio. In fact, this ratio can be calculated for each pair of teeth from the central incisor to the first permanent molar. This set of ratios, known as comprehensive cumulative percentage ratios (CPRs), can be used not only to determine which tooth or teeth have a tooth width discrepancy, but ca...
متن کاملIntermaxillary tooth size discrepancies among different malocclusion groups.
The aims of this study were to identify possible gender-related differences in tooth size ratios, to determine whether there is a prevalence for intermaxillary tooth size discrepancies in any malocclusion group, and to detect the percentage of tooth size discrepancies outside 1 or 2 standard deviations (SDs) from Bolton's mean. The material comprised the models of 500 subjects (284 females and ...
متن کاملBolton's intermaxillary tooth size ratios among Iranian schoolchildren.
OBJECTIVES The aims of the present study were to determine anterior and total tooth-width ratios in a representative Iranian sample in Tabriz city and compare them with the Bolton standards. STUDY DESIGN A total of 54 Iranian schoolchildren (12-14 years old) in Tabriz were examined. Alginate impressions were taken for subjects and poured by the dental stone. The mesiodistal widths of the teet...
متن کاملA computerized tooth-width analysis.
T ooth-width ratios are used diagnostically to quantify the harmony between the mandibu-lar and maxillary arches. A number of analyses have been developed to compare the tooth-width ratios of malocclusions to standardized norms. 1-4 The Ho-Freer Graphical Analysis of Tooth-Width Discrepancy (GATWD) provides a simple graphic description of tooth-width relationships between the arches, a comprehe...
متن کاملMesiodistal sizes and intermaxillary tooth-size ratios of two populations; Spanish and Peruvian. A comparative study.
INTRODUCTION Adequate tooth-size ratios are required to ensure the satisfactory outcome of orthodontic treatment. Consequently, various methods of measuring tooth-size ratios have been developed being the Bolton ratio the most commonly accepted, known and used one. This ratio depending directly on mesiodistal tooth size has been associated with different ethnic backgrounds. Some authors suggest...
