A Comparative Analysis Of Depth of Curve Of Spee Between Individuals with Normal Dentition And Individuals With Occlusally Worn Out Dentition

Abstract

Introduction: The curve of spee plays an important role to create Christensen’s phenomenon in natural dentition. This study was performed to assess the difference in depth of the curve of Spee between normal and attrited dentition.

Methods: An analytical cross-sectional study was performed to measure the depth of curve speed in a total of 80 willing participants who met the inclusion criteria, of which 40 had normal dentition and 40 had attrited dentition. Measurements were done on stone casts by using a rigid metal scale and a digital vernier caliper. Analytical statistical analysis (independent t-test) was done using SPSS Statistical Software Package (version 21.0).

Results: There was a statistically significant difference in the depth of the curve of Spee between the two groups.

Conclusions: The depth of the curve of spee decreases with the advancing of the age of human as attrition of the teeth occurs with age. Although there is a decrease in the depth of the curve of spee it should be maintained and created while performing full mouth rehabilitation and other extensive prosthodontic treatments.
