Aim: to study the inclination of the palatal plane in 95 subjects with clinically normal occlusion. Methods: the study was made using lateral headfilms and the results showed that in normal occlusion the extension of the palatal plane (ANS-PNS) passes trough the most posterior and inferior region of the skull, defined as Point “OPI”. Results: OPI.Ena.Enp mean value was -0.13º, close to zero. Conclusion: the results indicated that in normal occlusion patients the palatal plane presents a tendency to be tangent with posterior cranial base.

Keywords: Palatal plane. Normal occlusion. Occipital bone. Cephalometrics.
