Web1 Sep 2016 · For both SNA and SNB angles, the sella-nasion represents the reference line. The A-point is the point at the deepest concavity on the anterior curvature of the maxilla, while the B-point is the corresponding point on the mandible. Consequently, the SNA captures the horizontal position of the maxilla in relation to the cranial base, while the ... WebThe mean value of SNA (82.43) is normal, whereas the mean of SNB (75.56) is smaller than normal; it shows that most of the cases are retrognathic mandible. There are many variations in the anteroposterior skeletal relationships in Class II division 2 malocclusion but mostly are retrognathic mandible. 2 The SNB (–0.453) correlation to Go 2 is stronger than …
