Abstract

Aims: To determine the ideal dimensions of the artificial dental arch by measuring the dimensions of dental arch of completely dentulous subjects and to find the relation of these dimensions to some facialmeasurements. Materials and Methods: The sample of study consisted of 54 completely dentulous adult subjects (24 females and 30 males) with Class 1 normal occlusion aged 19–24 years. Dental casts were taken for each subject and the dimensions of the dental casts and the facial measurements were made by using digital vernier caliper. The data were analyzed with Statistical Package for Social Science program. Results: The dimensions of the dental arches and the facial measurements of themale group was larger than that of female and there was high correlation between some dimensions of dental arch with some of the facial measurements. Conclusions: The width of the dental arches of theartificial dental prosthesis could be determined depending on the extraoral facial measurements as the percentage of upper intercanine distance to mouth width is 74.43% and the percentage of the upperinter first molar distance to bizygomatic width was 40.65%

Abstract

Background: This study aimed to determine whether there is a relationship among the bite force with facialdimensions and dental arches in a sample of Iraqi adults with Class I skeletal and dental relations.Materials and methods: Forty dental students (20 males and 20 females) were selected under certain criteria. Forthose individuals, dental impressions, frontal facial photographs and maximum bite force at molar and incisor regionswere taken. The dental arches widths and facial dimensions were measured using the AutoCAD program 2007, whilethe bite force was determined using special device. Descriptive statistics for the measured variables were performedand gender difference was determined using independent sample t-test, while the relation among bite force andfacial dimensions and dental arches widths was determined by Pearson’s correlation coefficient test.Results: The results indicated that bite force, facial dimensions and dental arches widths were higher in males thanfemales with a non-significant genders difference for the bite force and upper inter-canine width, while with a highsignificant genders difference for the other measurements. Pearson’s correlation coefficient revealed non-significantcorrelation among the bite force and facial dimensions and dental arches widths.Conclusion: This study proved that there was no relationship among the bite force with facial dimensions and dentalarches widths
