Abstract

Purpose: The present study aims to assess the environmental effects that tongue posture, upper airway and maxillary dentoalveolar morphology have with respect to their association in skeletal Class II malocclusion cases.
Materials and methods: Pre treatment lateral cephalograms and study models of 32 adult skeletal Class II malocclusion orthodontic patients were selected randomly. Tongue posture measured as tongue to palate distance along 7 different lines and 3 linear upper airway parameters were determined cephalometrically. For maxillary dentoalveolar morphology, Inter canine width (ICW) and Intermolar width (IMW) was determined on study models. Pre treatment lateral cephalogram and study models of equal number of age matched skeletally Class I malocclusion patients were included as controls in this study.
Results: The mean measurement for tongue posture along 5 of the 7 reference lines are significantly higher in controls compared to the cases (P-value<0>0.05 for both).
Conclusion: A definitive pre treatment, mid treatment and post treatment assessment of tongue posture and upper airway on a lateral cephaogram and dentoalveolar morphology on study models is important in management of adult skeletal Class II malocclusion cases.

Keywords: Tongue posture, upper airway, dentoalveolar morphology, skeletal class II malocclusion.
