Which plane is defined as running from the ANS to the PNS?

The palatal plane is defined as running from the Anterior Nasal Spine (ANS) to the Posterior Nasal Spine (PNS). This anatomical reference provides a crucial baseline in cephalometric analysis as it helps in assessing the vertical and horizontal relationships of craniofacial structures. By establishing a standard plane of reference, dental professionals can make more accurate assessments regarding the positioning of the maxilla and mandible, along with their relationship to the cranial base and other dental structures.

In orthodontics and dentofacial analysis, the palatal plane is particularly significant as it represents an important orientation for evaluating growth patterns and planning treatments. Understanding its definition facilitates clearer communication among professionals and contributes to more effective diagnostic and treatment approaches in orthodontics and related fields.
