Assessment of mandibular retrognathism and maxillary prognathism as contributory factors for skeletal Class II malocclusion: A cephalometric study p. 99 Suraj Prasad Sinha, Krishna U S Nayak, Crystal Runa Soans, PS Murali, Akhil Shetty, MS Ravi DOI:10.4103/ijohs.ijohs_3_18 Aim: The aim of this study is to evaluate the skeletal factor (maxillary excess and/or mandibular deficiency) contributing for the skeletal Class II malocclusion. Materials and Methods: Lateral cephalograms of 100 individuals (50 males and 50 females) in the age group of 18–30 years, having skeletal Class II malocclusion with ANB of more than 4, were evaluated. The parameters to be used for prediction of maxillary prognathism include linear measurement of Nasion perpendicular to point A, and for the mandibular retrognathism, it is linear measurement of Nasion perpendicular to Pogonion, as suggested by Burstone analysis. Results: The 34% of the studied sample size had the Class II skeletal pattern (ANB >4), but
