Abstract:
BACKGROUND AND OBJECTIVES: Morphological indicators within the cranium for prediction of mandibular growth patterns as reported by Bjork are: (1) Inclination of the condylar head (ICH), (2) Curvature of mandibular canal (CMC), (3) Shape of the lower border of the mandible and specifically depth of the antegonial notch (AN), (4) Inclination of the symphysis (ISY), (5) Interincisal angle (IIA), (6) Intermolar angle (IMA), (7) Lower anterior facial height (LAFH). The purpose of this study was to examine the association of AN, ISY and CMC in Angle’s Class II Division 1 malocclusion among three skeletal facial type (average, horizontal and vertical) and to assess which amongst these signs are more representative of each skeletal facial types in the vertical plane in skeletally mature subjects. MATERIALS AND METHOD: The pre-treatment lateral cephalometric radiographs of 30 post-growth subjects undergoing orthodontic treatment from Dept. of Orthodontics, M.R. Ambedkar Dental College, Bengaluru were selected and divided into three groups according to their MP-SN (according to Steiner’s analysis) 1. Normal: 26-38 degrees (G1), 2. Horizontal: <26 degrees (G2), and 3. Vertical: >38 degrees (G3). RESULT: Statistical test carried out were One way ANOVA and post hoc Tukey’s test. It was found that AN, ISY and CMC were statistically significant between the groups. CONCLUSION: Bjork’s implant studies have contributed much to understanding facial-skeletal growth. The present study concluded that Antegonial notch depth (AN), Symphysis morphology (ISY) and Curvature of mandibular canal (CMC) were the reliable parameters evaluating Bjork’s indicators in Angle’s Class II Division 1 malocclusion among extreme skeletal Patterns.
