Relationship between antegonial notch & vertical growth pattern

Abstract

Aim: To correlate the depth of the antegonial notch to the mandibular growth direction. 
Material & methods: Pretreatment cephalograms of 60 patients were taken. Allcephalograms were 
taken by the same operator. The patients were categorized as normodivergent, hypodivergent & 
hyperdivergent based on FMA & SN-GoGn angle. Depth of the antegonial notch was assessed. 
Results: Comparison of antegonial notch depth of different groups revealed that antegonial notch was 
found to be deepest in hyper divergent growth pattern (2.743 mm+0.3211 ) followed by 
normodivergent growth pattern (1.641 mm+0.6432 ) & least in hypo divergent growth pattern 
(0.745+0.7251 mm ).
