Correlation of bjork’s morphological indicators with the prediction of mandibular growth in skeletally mature patients

Background: Mandibular growth is important in determining the growth pattern of an individual and various morphological indicators are used to predict its growth pattern. Objectives: The objective of this study was to correlate these indicators with prediction of mandibular growth in skeletally mature patients. Material and methods: Pre–treatment lateral cephalograms were randomly selected and divided into 60 males and 60 females and were further subdivided: Average {Group I} (MPA= 28-360) , Hypodivergent {Group II} (MPA= ≤260) , Hyperdivergent {Group III} (MPA= ≥380) (20 each) and measurements obtained were statistically analysed. Results: Significant differences were found among all the parameters, however these differences varied from one group to another. Conclusion: Lower anterior facial height is the most important parameter while determining hyperdivergent growth pattern and Curvature of mandibular canal can be considered to be a reliable indicator for hypodivergent growth pattern.
