Arch width, arch length, and tooth size in young adult males.
In the mandibular arch also an increase in mandibular intercanine width, inter 1st premolar width, inter 2nd premolar width and inter molar
arch width was observed (Table 1) similar to maxillary arch.
A study about tooth size and
arch width measurement.
Arch width: The maxillary
arch width was significantly less in the affected group compared with healthy controls in all dimensions, P values were less than 0.03 (table 1).
The effect of sucking habits, cohort, sex, intercanine
arch widths, and breast or bottle feeding on posterior crossbite in Norwegian and Swedish 3-year-old children.
The purpose of this study was to characterize the biting force, dental
arch width and N - Gn and Zr - Zl dimensions.
The objective of this study was to evaluate the respiratory pattern in children in the mixed dentition by means of acoustic rhinometry and its relation to the upper
arch width development.
Evaluation of
arch width variations among different skeletal patterns in South Indian population.
Hence, it may be suggested that orthodontic plaster models, photocopies and digitized images of the models are suitable reproductions for taking measurements of the anterior and posterior dental
arch width. The results of the present study were generally consistent with those reported by Champagne [12] (1992).
Crowding is defined as a discrepancy between tooth size and arch size that results in malposition and/or rotation of teeth.1 Crowding of the dentition is usually attributed to discrepancies in tooth size and arch length and
arch width.2-5 The goal of modern orthodontics is to provide the best possible occlusal relationships within the acceptable framework of facial aesthetics and stability of results.
These considerations, in addition to antero-posterior movements of the dentition determine the requirements for extraction or non extraction treatment planing.7 Size and shape of the dental arches could be affected by many factors such as heredity, growth of the bone, eruption and inclination of the teeth, racial background and environmental factors such as muscle forces and function.8
Arch width has been a subject of interest among investigators; studying the growth of dental arches.
Pont established constant ratios between tooth sizes and
arch widths in French population which came to be known as premolar and molar indices.5 In the ideal dental arch, he concluded that the ratio of combined incisor width to transverse
arch width was 0.80 in the premolar area and 0.64 in the molar area.
