Evaluation of facial asymmetry using digital photographs with computer aided analysis.

Facial asymmetries exist in all individuals. Due to these facial asymmetries that exist, a standardized approach in locating the occlusal plane that is parallel to the ala-tragus and interpupillary lines, may result in less than ideal esthetics in the final restoration. The challenge for the prosthodontist is to determine an acceptable occlusal plane with an individualized approach that can be used as a guide for alignment of the maxillary anterior teeth in cases that require their replacement or extensive restoration. The present study uses an inexpensive and standardized digital photographic technique along with computer assisted analysis to measure the asymmetries of the human face. Statistical Analysis used-Karl pearson's correlation coeffient was used. The correlation coefficient was then subjected to 't' test and 'p' value was used to find out the level of statistical significance. Left side of the face was found to be at a higher level than the right side.
