Study to Establish Occlusal Plane Relationship to Three Different Facial Lines
Journal Title: Journal of Advanced Medical and Dental Sciences Research - Year 2017, Vol 5, Issue 9
Abstract
Introduction: The aim of the study is to compare the relationship of the occlusal plane to 3 different ala-tragal lines, namely the superior, middle and inferior lines, in individuals having different head forms and its relation to the Frankfort horizontal plane. Materials & Methods: A total of 75 lateral cephalometric radiographs of subjects with natural dentition, having full complement of teeth, between the age group of 18-25 were screened and selected. Prior to making the lateral cephalogram, radiopaque markers were placed on the superior, middle and inferior tragus points and on the inferior border of the ala of the nose. Cephalometric tracing was done over each cephalogram. Resutls: In mesiocephalic head form the middle ala-tragal line was most parallel to the occlusal plane having a mean angle of (1.96˚). In dolichocephalic headform the superior ala-tragal line was most parallel to the occlusal plane having a mean angle of (0.48˚). In brachycephalic head form the middle ala-tragal line was most parallel to the occlusal plane having a mean angle of (2.08˚). Discussion & Conclusion: The relationship between occlusal plane and Frankfort horizontal plane which is considered a reference line in orienting the maxilla does not very much in the three different head forms,
