Effects of functional therapy on hyoid bone, pharyngeal airway and tongue position in class II patients
Journal Title: IP Indian Journal of Orthodontics and Dentofacial Research - Year 2018, Vol 4, Issue 1
Abstract
Aim The aim of this study is to evaluate the change in the position of hyoid bone pharyngeal airway and tongue position in subjects with skeletal Class II malocclusion treated with Twin block therapyMaterials and Methods This study was performed on pre and post treatment lateral cephalograms of 21 patients with class II malocclusion treated with Twin block appliance mean age of 1224plusmn 122 Pairedt test was used to compare the amount of differences of mean value before and after treatment A value of Plt005 was considered as significantResult Hard tissue result showed significant difference between preand posttreatment values of ANB HyB HyMe amp HyCL But no significant difference was seen between the preand posttreatment values of HySN amp HyFHP Soft tissue examination also found significant difference between preand posttreatment values of SPAS but no significant difference was observed between the preand posttreatment values of MAS IAS PTCL amp PTSNConclusion ANB angle was found to be significantly improved after functional treatment in skeletal class II group The mandible has showed forward movement with respect to hyoid bone and the hyoid bone has been found to be shifted anteriorly and downward Superior pharyngeal space was found to be significantly improved after functional therapy whereas there was no significant change with respect to tongueKeywords Hyoid bone Pharyngeal airway Tongue Twin block Lateral cephalogram
