Objective: To check the reliability of various horizontal parameters for predicting the Class I,Class II,Class III malocclusion and  the reliability of various vertical parameters for predicting the normodivergent, hypodivergent  and hyperdivergent  growth patterns. Material and methods: The study was carried out in the Department of Orthodontics and Dentofacial Orthopedics, Bhojia Dental College and Hospital, Baddi, (H.P). Ethical clearance from institutional ethical committee was taken for conducting study. A complete history and examination of all the subjects was done at the ESI hospital, Baddi, prior to their inclusion in the study.A total of 80 subjects  with age group of 16-28 years were selected for the study . Sample size of 80 subjects were divided into three groups based on Angle’s classification:-  Group 1: Angle’s class I Malocclusion  Group 2: Angle’s classII Malocclusion    Group 3: Angle’s classIII Malocclusion . The same subjects were divided into 3 groups based on the values obtained by measuring the clinical FMA  with modified facial goniometer   Group I:FMA (18-26degree) Normodivergent  Group II: FMA(<18 degree) Hypodivergent  Group III: FMA(>26degree) Hyperdivergent . Lateral cephalograms of all the 80 subjects were taken in standardized manner in the same cephalostat machine and were traced for  various vertical and sagittal parameters and the readings were evaluated and compared for results. Results: After the statistical analysis of factor analysis and ANOVA of the data it was found that out of the vertical parameters with a sample size of 80 patients 53 patients fall under horizontal growth pattern and 27 under vertical growth pattern and none in normodivergent and in sagittal parameters 28 fall under Class-I, 49 under Class-II, and 1 under Class-III. Conclusion: In short statistically significant parameters reliable for finalizing the type of growth pattern are Bjork sum, Y-axis, Mandibular plane angle, J-ratio. The reliable parameters for finalizing the type of malocclusion are ANB, Yen angle, APP-BPP.
Key words: Cephalometrics, Growth pattern, Malocclusion.
