The aim of this study was to compare the depth of curve of Spee (COS) in AngleClass I, Angle Class II and Angle Class III malocclusions.Materials and methodsThe Samples were chosen among the diagnostic materials in İstanbul MedipolUniversity Department of Orthodontics. Ninety plaster models were chosen,and were divided into 3 groups (n=30) according to Angle dental malocclusionclassification. The depth of curve of Spee was measured on left and right sides ofmandibular dental models and mean values were used as depth of curve of Spee.ANOVA test was used to evaluate normally distributed data. Comparison of thesides were performed by using paired sample t test. Significance level was set top<0.05.ResultsThe depth of COS was found as deepest in Class II malocclusion (2.9±0.8 mm)and was relative flat in Class III malocclusion (2.1±0.9 mm) and the difference wasstatistically significant (p<0.05). No significant difference was found between AngleClass I and Class III malocclusions.ConclusionSince the depth of curve of Spee is increased in Class II malocclusions, this factorshould be considered in treatment planning.
