Palatal rugae have been suggested as a stable landmark and potential biometric
guide for positioning anterior maxillary teeth. This study aimed to evaluate the use
of palatal rugae as a biomarker by establishing mathematical correlations with
anterior maxillary dental arch geometry and tooth positions. One hundred dental
casts were obtained from fully dentate individuals with normal occlusal relationships.
Thirteen reference points were analyzed. Significant correlations were found between
measurements in the anterior dental segment and palatal rugae measurements.
Those correlation coefficients were, however, low. Although some correlation values
obtained were statistically significant, they are not likely to have significant clinical
predictive value. Int J Prosthodont 2013;26:227–229. doi: 10.11607/ijp.3167
