Objectives: This clinical study was carried out to determine the relationships between maxillary anterior teeth width [canine arc distance, central incisor width], and certain horizontal facial parameters which include: [(Interzygomatic, inner and outer canthus and interpupillary) distances, and (interalar, mouth and philtrum of upper lip) widths], to be used as a guide to selection   of the maxillary anterior teeth width.

Materials and Methods:
The facial measurements were taken directly from (60) under-graduate students in age range (19-24) years old by using an electronic digital vernier caliper. While canine arc distance and central incisor width were measured indirectly on the casts made from impressions of the selected subjects using flexible millimeter ruler. The collected data were analyzed and correlated using statistical package SPSS version 20.

: The mean value of all the parameters measured were significantly higher in males than female, for male just a significant correlation was found between canine arc distance and mouth width, CARCD =0.994×MW, while for females significant correlation was found between canine arc distance  mouth width, inner and outer canthal distance, and interpupillary distance, but the most significance relation was with the mouth width, CARCD=1.036×MW, and central incisor width was significantly correlated with, mouth width, CIW = MW ÷6.15, CIW = MW ×0.16. 

: This study demonstrated that certain horizontal facial parameters could be used as a guide in maxillary anterior teeth width selection to achieve an optimal esthetic result for each gender.

Keywords: Facial measurement, teeth width, teeth selection, and teeth size.
