Measuring curve of spee using digital methods and defining its relationship to different angle classes

Abstract

Aim of the study: This cross-sectional study is aiming for investigating the relationships of the depth of curve of Spee with different Angle classes.Materials and Methods: A sample of 240 study models were collected and scanned digitally to measure the depth of curve of Spee. The sample has been divided into 4 groups including: Angle Class I, Angle Class II Division 1, Angle Class II Division 2 and Angle Class III with 60 study models in each group. The depth of the curve of Spee has been measured from the left and right sides and the mean value of both sides was calculated.Results: The measurement of curve of Spee showed significant differences between different classes (p
