Palatal Plane is defined by which landmarks?

Explanation:
The Palatal Plane is defined by the line joining the Anterior Nasal Spine (ANS) and the Posterior Nasal Spine (PNS). The order of the points doesn’t matter, so PNS-ANS is the same plane as ANS-PNS. This plane serves as a maxillary reference in cephalometrics to evaluate the orientation of the maxilla and vertical relationships. It is distinct from the Frankfort Horizontal (through Porion and Orbitale) and from the Sella-Nasion plane.
