Three-Dimensional Assessment of Collum Angle in Different Sagittal Malocclusions: A Cross-Sectional Study.

Introduction: Assessment of crown-root angulation of the anterior teeth as defined by the collum angle (CA) is crucial for diagnosis and treatment planning. This study was undertaken to evaluate the CA of all anterior teeth within both the maxillary and mandibular arches across various sagittal malocclusions using cone-beam computed tomography (CBCT). Additionally, the secondary aims included investigating sex disparities and side variances in this angular measurement.
