Summary

Most primary maxillary dental casts show asymmetrical arches, with variations in arch form. Rounded and short arch types tend to be more symmetrical than long arch types.

Area of Science:

  • Dentistry
  • Orthodontics
  • Dental Morphology

Background:

  • Understanding the normal variations in primary maxillary dental arch form and symmetry is crucial for early detection of potential orthodontic issues.
  • Previous research has established general patterns, but detailed classification of arch forms and their correlation with symmetry in primary dentition requires further investigation.

Purpose of the Study:

  • To identify and quantify arch symmetry in normal primary maxillary dental casts.
  • To describe and classify variations in primary maxillary dental arch form.
  • To explore the relationship between different arch forms and arch symmetry.

Main Methods:

  • Analysis of 62 normal primary maxillary dental casts.
  • Assessment of dental arch symmetry (symmetrical vs. asymmetrical).

  • Classification of arch forms based on the ratio of arch width to length, identifying six distinct types.

    • Main Results:

    • 62% of the analyzed dental casts exhibited asymmetrical arches, while 38% showed symmetrical arches.
    • Six distinct types of maxillary arch forms were identified based on width-to-length ratios.
    • A higher prevalence of long arch types was observed compared to short arch types.
    • Rounded and short arch forms demonstrated a tendency towards greater symmetry compared to long arch forms.

    Conclusions:

    • Asymmetry is the predominant characteristic of normal primary maxillary dental arches.
    • Maxillary arch form in primary dentition can be systematically classified, with distinct variations observed.
    • Arch form significantly influences arch symmetry, with shorter and rounded forms being more symmetrical.
