The purpose of this study is to analyze the width and length changes of the dental
arches during the primary, mixed and early permanent dentition. 1800 stone models of
maxillary and mandibular arches obtained from the children aged 3 to 11 years old were
under measurement.
The results were as follows ;
Arch widths and lengths differed with age, sex and jaw.
1. Width of dental arches showed increase tendency according to increasing age.
2. Lengths of dental arches remained somewhat stable.
3. The dental arches of males were wider and longer than those of females.
