Abstract

Aim: The aim of the present study was to find the association between head posture and type of malocclusion using Digimizer software.
Material and Method: Pre-treatment lateral cephalograms of 90 patients were divided into 3 malocclusion groups, Class I (n=40), Class II (n=40) and Class III (n=10) malocclusion groups on the basis of ANB angle and WITS appraisal. Amongst these three malocclusion groups, relationship between the head posture and malocclusion was evaluated by measuring 9 postural angles and 8 malocclusion traits.
Results: Cranio-horizontal angles were maximum in Class I malocclusion followed by Class II then Class III malocclusion. Amongst Cranio-cervical angles, SN-C2, SN-C4 angles were maximum in Class III malocclusion followed by Class II then Class I whereas Pal-C2,Pal-C4 angles were maximum in Class II followed by Class I then Class III. Cervical curvature angle was maximum in Class II followed by Class I then Class III. None of these angles determining head posture showed significant difference between the subjects with different malocclusion. Correlation coefficient observed were in range of 0.3 to 0.4 and had less predictive value.
Conclusion: Development of malocclusion has multifactorial etiology, of which headposture is one of the factors resulting in malocclusion. This could be the reason thatvariabilities in postural angles determining head posture was seen in differentmalocclusion groups but difference was not significantand correlation coefficient had lesspredictable value.
Keywords: Head posture, Malocclusion, Lateral cephalograms, Cranio-vertical angle,Cranio-cervical angle, Cervical curvature.
