Dimensions and form of dental arches in subjects with normal occlusions

American Journal of Orthodontics and Dentofacial Orthopedics, 1993
To determine the main mandibular dental arch forms, 278 dental casts of untreated French adults with normal occlusions were examined. Six measurements of the mandibular dental arches were performed, and five independent ratios were determined. By following the k-means clustering method on the basis of these ratios and the use of polynomial functions of

Age changes in dental arch dimensions of Australian Aboriginals

American Journal of Physical Anthropology, 1983
AbstractBreadths and depths of the dental arches were measured from standardized photographs of serial casts of Australian Aboriginals enrolled in a longitudinal growth study. The data were obtained from 1161 sets of casts representing 111 boys and 86 girls ranging in age from 6 to 19 years.

Late lower arch crowding: The role of the transverse dimension

American Journal of Orthodontics and Dentofacial Orthopedics, 1995
Fifty subjects who were followed longitudinally between 13 and 18 years showed an average increase in lower arch crowding of 2.36 mm. This increase in crowding was examined in relation to tooth width, arch width and jaw width, actual and relative, and to changes in these dimensions with correlation and multiple regression analyses.

Maxillary arch dimensions in Saudi and Egyptian population sample

American Journal of Orthodontics, 1984
Observations relating to maxillary arch dimensions were obtained from 243 randomly selected subjects. The group consisted of 146 Saudi subjects with an average age of 24 years and 97 Egyptian subjects with an average age of 27 years. The measurement distances from canine to canine (C-C), molar to molar (M-M), molar to canine (M-C), and molar to incisor

Heritability of dental arch dimensions in humans.

Journal of craniofacial genetics and developmental biology, 1992
The purposes of this study were to estimate the heritabilities of several human dental arch dimensions and compare the hereditary differences among kinships and among variables. The sample consisted of 102 Japanese families, each including both parents and one of their offspring, and on average all subjects had relatively well-aligned permanent ...

Relation between combined widths of incisors and dimensions of the dental arches

European Journal of Oral Sciences, 1972
abstract – The correlation between the total widths of the incisors and the widths and lengths of the dental arches was studied in 149 boys and 175 girls, aged 8 years 10 months to 11 years 10 months. Eighty‐two of the children were judged as having normal occlusion. The widths and lengths of the dental arches were positively correlated with the total

Stress Amplification and Arch Dimensions in Proppant Beds Deposited by Waterfracs

SPE Production & Operations, 2009
Summary Equations and a procedure have been developed to calculate the excess stress induced on a proppant dune that is deposited by a waterfrac with poor proppant-transport characteristics. This method also calculates the dimensions of an arch region that forms above the bed.
