A New Method for Dental Cast Analysis

Abstract

Objectives: This study aimed to develop a new method of dental cast analysis using angular measurements.
Materials and methods: One hundred study models belong to 100 Iraqi healthy adults with class I occlusion
were assessed using Planmeca dimax software. Three angular measurements at the levels of maxillary
canines, second premolar and second molars cusp tips with the tip of the angles at the midpoint between
the two central incisors were measured. Gender difference was evaluated by unpaired t-test and the relation
between the angles was assessed by Pearson’s correlation coefficient test.
Results: The results revealed higher mean values of the measured parameters in males with direct, moderate
to strong, significant correlation.
Conclusions: A new method was developed and could be used to assess the growth and treatment changes
in the future researches.
