To evaluate the morphology of dental arches, 62 (male: 36, female: 26) paired casts having normal dentitions and occlusion were selected from 396 (age: 18 to 26 years old; male: 257, female: 139) sets of dental study models. The maxillary dentitions were preliminarily classified as square, round-square, round and round V-shaped arches based on the conventional morphological descriptions. Midpoints of the incisor edge (I1(R), I1(L), I2(R), & I2(L), summits of the cuspids (CR & CL), buccal cusps… 

Figures and Tables from this paper

Morphological classification of mandibular dental arch forms by correlation and principal component analyses.

Morphology of the mandibular arch was determined by a parameters representing the curvature of anterior teeth and the curvilinear contour of the dental arch, and the length-to-width ratio of theental arch.

Comparison of distance between maxillary central incisors and incisive papilla in dentate individuals with different arch forms.

Ovoid type of arches was the commonest arch form seen in either sex and there is no significant difference between males and females in 3/4th of dentate individuals, regarding the type of dental arch as well as CI-IP distance.

The relationship of maxillary arch dimension with vertical facial morphology in proto-malay race

A significant positive correlation between intercanine and intermolar width and a negative correlation between arch length and palate height with vertical facial morphology in the male and female groups within the Proto-Malay race.

Correlation between the distance of maxillary central incisors and incisive papilla in different arch form

It can be concluded that gender factor was irrelevant towards the CI-IP distance regardless of the individual arch form, however, there was a correlation between the CI -IP distance in different arch forms in both male and female sample.

Shape of the Upper Alveolar Arch in Albanian Subjects

To the authors knowledge this is the first published study related to Albanian subjects and further investigations concerning arch size data, are needed.

Dental Arch Size, Biting Force, Bizygomatic Width and Face Height in Three Colombian Ethnic Groups

The amazon TicunaIndian ethnia has a significantly higher bite force, higher dental arch transversal width and higher bizygomatic width than the other two ethnic groups considered.

ARCH FORM ANALYSES: A COMPARISON OF TWO DIFFERENT METHODS

The ovoid arch form was most common arch form according to both methods and there was a statistically significant difference in the results of two methods as well as their frequency distribution.

Assessment of The Relationship of Incisive Papilla to Maxillary Central Incisor and Canine-Papilla-Canine Line among the Dentate population of Central Nepal.

Results suggest that incisive papilla is a reliable biometric guide which would help to reduce the clinical time of both the dentist and the patients in placement of the anterior teeth.

Computer-guided technique evaluation of the bony palate for planning individual implant placement

The primary principle in reconstructive treatment should be describing geometrical forms and mathematical details of the bony palate in three-dimensional reference values relative to the dental arch to increase the success of individual treatment of surgical procedures and reduce possible complications.

The relationship of facial and dental midlines with various anatomic landmarks of face and oral cavity

The aim of the study was to find out the relative reliability of different clinical anatomical landmarks to determine the midline of face and the hierarchy of facial anatomical landmarks closest to
