RADIUS OF CURVE OF SPEE IN PATIENTS REFERRING TO THE ORTHODONTIC DEPARTMENT OF TERTIARY CARE HOSPITAL

Abstract

Study was done to determine mean of radius of curve of spee in different vertical pattern.

Curve of Spee is a naturally occurring phenomenon in the human dentition. This normal occlusal curvature is required for an efficient masticatory system. Exaggerated curve of Spee is frequently observed in dental malocclusions with deep overbites.1 Such excessive curve of Spee alters the muscle imbalance, ultimately leading to improper functional occlusion.It was cross sectional study design with 211 patients from department of Orthodontics, dental OPD Karachi Medical and Dental College, Abbassi Shaheed Hospital, Karachi, Pakistan. The data collection procedure was non–probability consecutive. Sampling procedure had inclusion criteria to be followed that included, No previous history of orthodontic treatment, healthy subjects having complete dentition, second molars erupted and except for third molars no other maxillary and mandibular teeth were absent. The exclusion criteria was also set for study including, any syndromic or cleft lip and palate subject will not be included, participants with history of trauma and patients with facial asymmetry. All the patients were examined by researcher. After thorough history and clinical examination for evaluating the inclusion and extrusion criteria patients were recruited for the study. All measurements were recorded on a predesigned Performa.
