Comparative assessment of changes in sagittal relationship of maxilla to mandible in class II malocclusion – a cephalometric study
Journal Title: IP Indian Journal of Orthodontics and Dentofacial Research - Year 2016, Vol 2, Issue 2
Abstract
A number of analyses have been done over the years with varying degrees of reliability and success in assessing the anterior-posterior jaw relationships of the jaw bases. These analyses have both advantages and inaccuracies corresponding with their use which needs to be understood. Aim: Comparison of various cephalometric parameters to assess the sagittal relationship of maxilla to mandible in class 2 malocclusion treated cases. Objective: To assess the changes in the sagittal relationship of maxilla to mandible after treatment of skeletal class II malocclusion and comparison of four angular and four linear cephalometric parameters. Method: This study includes 21 subjects with class II malocclusion selected based on inclusion and exclusion criteria and with an age ranges of 18 to 25 years. Manual cephalometric tracing has been done on pre and post treatment lateral cephalograms and four angular and four linear parameters are measured. Results: The YEN angle is a highly reliable angle and both YEN and Beta angle have significantly improved in most of the class II cases.
