AbstractAims:To evaluate the relationship between some of facial parameters including [(alae of nose, mouth, philtrum of upper lip) widths with interzygomatic distance] and straight maxillary intercanine distance for clinical application advantage. Materials and Methods: In this clinical study, (140) dental students in College of Dentistry/University of Mosul were examined and their facial and dental measurements were taken directly from each student by using an electronic digital vernier caliper. The data were collected and analyzed with computer to determine the correlation between the studied factors.Result: The results of this study demonstrated that all the measured parameters were larger in males than females which being statistically different between the two sexes and the Pearson Product Moment Correlation Coefficient test revealed that non of the facial parameters were measured had a significant correlation with straight maxillary intercanine cusp tips distance in females, while both of interzygomatic distance and philtrum width of upper lip had a significant correlation with straight maxillary intercanine cusp tips distance in males which they could be used to determine this distance for replacement of maxillary anterior teeth in males. Conclusion: Depending on previously mentioned results the straight maxillary intercanine distance was equal to interzygomatic distance divided by a factor of( 3.3), while multiplying the width of the philtrum of upper lip with a factor of ( 2.75) gives us an estimation of the straight maxillary intercanine cusp tips distance.
