Abstract
Introduction: Selection of appropriately sized maxillary denture teeth in various types of arch form is often a challenging aspect during complete denture rehabilitation. The correlation of facial anatomical landmarks may serve as a reliable predictor for the selection of teeth.
 Materials and methods: The maxillary arch impression of 113 dentate subjects were made, casts poured and divided into square, ovoid and tapering arch form. The position of tip of maxillary canines in relation to commissure of mouth and midpupillary line were determined by using vacuum formed template and pupillometer respectively.
 Results: The result showed the significant difference in mean distance from commissural to canine tip (p<0.001) and IPD (p<0.017) among square, ovoid and tapering arch form.
 Conclusion: The commissure of lip may serve as a reliable guideline for selection of anterior teeth according to arch form and IPD/ICW can similarly be used to determine anterior teeth width.
Highlights
Selection of appropriately sized maxillary denture teeth in various types of arch form is often a challenging aspect during complete denture rehabilitation
The mean position of tip of maxillary canine is mesial to midpupillary line by 11.87 ± 2.32mm in square, 11.54 ± 1.42mm in ovoid and 11.05 ± 1.73mm in tapering arch form
Comparison of mean among square, ovoid and tapering arch form showed that there was no significant difference in mean distance from midpupillary line to canine tip among three arch form indicating a weak positive correlation

The position of tip of maxillary canines in relation to commissure of mouth and midpupillary line were determined by using vacuum formed template and pupillometer respectively.
