OCCLUSAL CURVATURE MEETS FACIAL FORM: INSIGHTS FROM MATHURA

The curve of Spee is a critical determinant of occlusion and dentofacial harmony.While variations in dentofacial morphology have been studied across populations, limited data exist for the Mathura population. This study evaluates the relationship between the curve of Spee and skeletal as well as dental parameters, with a focus on sexual dimorphism. Aim & Objectives:To evaluate the curve of Spee in mandibular arches of the Mathura population.To assess its relationship with dentofacial morphology.To determine sexual dimorphism. Materials and Methods:A total of 160 subjects (80 males, 80 females) aged 18-24 years with Class I molar relationships and minimal crowdin g were selected. Lateral cephalograms were used to record angular and linear measurements. Dental models were prepared to measure the curve of Spee, occlusal plane, intercanine and intermolar widths, arch length, and dental arch form. Statistical analysis was performed to evaluate correlations and regression.
