Pont’s Index and Dental Arch Form
The Journal of the American Dental Association, 1972Pont’s index is an average measurement for a group, and although it can be applied to all group members, it must not be applied to the individual. Participants in the study (Navajo males and females, and dental students) had ideal occlusions with crowding or spacing of less than 1 mm.

Shortened dental arches and periodontal support*
Journal of Oral Rehabilitation, 1991SummaryThe periodontal support of subjects with shortened dental arches (SDA, n=74), and of subjects with SDA and free‐end removable partial dentures in the lower jaw (SDA and RPD, n=25) was compared with that of subjects with complete dental arches (CDA, n=72). The periodontal support was determined by tooth mobility and alveolar bone height, measured

Longitudinal dental arch changes in adults
American Journal of Orthodontics and Dentofacial Orthopedics, 1998This study examined changes in the dental arches that occur in untreated persons between late adolescence and the fifth or sixth decade of life. Longitudinal dental casts from 82 subjects were obtained as part of a recall study of subjects from the University of Michigan Elementary and Secondary School Growth Study. From the parent sample, three groups

An analysis of dental arch form
The European Journal of Orthodontics, 1987The changes in maxillary arch form induced by two closely analogous orthodontic therapies were assessed from study models of Angle's Class II, division 1 patients. The traditional linear arch width and length dimensions proved difficult to interpret, however, as these parameters combined size and shape together.

Occlusal Stability in Shortened Dental Arches
Journal of Dental Research, 2001Shortened dental arches consisting of anterior and premolar teeth have been shown to meet oral functional demands. However, the occlusal stability may be at risk as a result of tooth migration. The aim of this nine-year study was to investigate occlusal stability in shortened dental arches as a function over time.

Dental arch dimensions in oligodontia patients
American Journal of Orthodontics and Dentofacial Orthopedics, 2008The aim of this study was to compare the dental arch sizes in a group of oligodontia patients with a group of age- and sex-matched untreated Class I control patients.Dental casts were measured of 50 oligodontia patients and 50 untreated Class I patients between 8 and 16 years old.

Abstract We have previously posed the question as to whether it is necessary to replace missing teeth. The loss of an anterior tooth will usually cause the patient to seek treatment as they would find the aesthetics unacceptable. This may not be the case if one or more of the posterior teeth are lost.

Non-human primate dental arch form
Cells Tissues Organs, 1977Multivariate statistical analysis, based upon a number of dimensions, showed significant contrasts in dental arch form between four primate groups, which was difficult to identify from subjective visual inspection. Furthermore, analysis of dental arch size was shown to differ from dental arch shape, although whether this reflected predominantly genetic

Shortened dental arches and masticatory ability
Journal of Dentistry, 1990In a previous study concerning oral function with shortened dental arches, it was found that approximately 10 per cent of the patients investigated complained of impaired masticatory ability despite a substantial reduction in arch length and, as a consequence, food platform area.

Age Changes in Dental Arch Shape
Journal of Dental Research, 1970Age changes in dental arch shape were assessed by computing the area of the arch and the arch index:Five-hundred and twenty sets of maxillary and mandibular casts were measured. They were taken from British patients within the age range of 3 to 15 years.
