Assessment And Correlation Of Changes In Cervical Lordosis Angulation Using The Novel Modified Cervical Curvature Angle (MCCA) Following Fixed Orthodontic Treatment.

BACKGROUND - The study aimed to assess and correlate changes in cervical lordosis angulation using the novel Modified Cervical Curvature Angle (MCCA) following fixed orthodontic treatment. It focused on evaluating alterations in cervical lordosis angulation by comparing pre- and post-treatment lateral cephalograms of orthodontic patients. Additionally, the study sought to determine the correlation between these changes and different skeletal patterns, providing insights into the relationship between orthodontic treatment and cervical spine alignment.MATERIAL AND METHODS - Pre-treatment and post-treatment lateral cephalograms of 30 patients who underwent fixed orthodontic treatment were selected in the department of orthodontics and dentofacial orthopaedics. Patients were divided into two groups, skeletal class I (Group I) and skeletal  class II ( Group II) in accordance with ANB angle and Wits appraisal .The assessment process  included evaluation of new defined MCCA (modified cervical curvature angle) angle .Changes  in  MCCA angle, cervical landmarks OPT/HOR, CVT/HOR and skeletal pattern between pre-treatment and post-treatment lateral cephalograms  were evaluated and correlated .MCCA angle  determined changes in cervical curvature of patients who underwent fixed orthodontic treatment. 27.0 statistical software was used to analyse the data. RESULTS - No statistically significant difference was found between the pre-treatment MCCA and post-treatment MCCA (p value = 0.078, NS). On correlating with skeletal pattern there was no significant difference found in pre and post -treatment MCCA angles with subjects having class I (p -value= 0.167, NS) and class II (p-value= 0.380, NS) Skeletal pattern who underwent fixed orthodontic treatment.CONCLUSION-There was no significant difference between pre and post-treatment MCCA (Modified Cervical Curvature Angle ) evaluated in pre and post-treatment lateral cephalograms of patients who underwent fixed orthodontic mechanotherapy indicating no impact on cervical lordosis after orthodontic treatment .On correlating changes in MCCA with both groups , there was no significant correlation indicating that skeletal relationship (Both class I and class II Skeletal  relationship) does not affect changes in cervical curvature after fixed orthodontic mechanotherapy .The Modified cervical curvature Angle (MCCA) demonstrated its reliability as a measurement tool for evaluating cervical curvature in this study. Its effectiveness in clinical settings supports its continued use in future research investigating the broader implications of orthodontic treatment on spinal health. By employing a standardized and reliable measurement method, researchers can enhance the comparability and validity of their findings, contributing to a more comprehensive understanding of the topic.
