Evaluate the Association between the Interpterygomaxillary Notch and the Width of Maxillary Anterior Teeth

Abstract

Aim: Among the most challenging aspect of complete denture construction is the proper selection of
maxillary anterior teeth. The main objective of this study was to examine the relationship between the total
mesiodistal width of the six maxillary anterior teeth and the interpterygomaxillary notch distance.
Materials and Methods: One hundred maxillary impressions were taken on subjects using irreversible
hydrocolloid impression material and stock trays. The distance between two pterygomaxillary notches
was measured on a straight line using a digital caliper with a 0.01-mm precision level. For each cast, the
maximum coronal widths of each of the maxillary anterior six teeth were measured with a caliper. The
results were analyzed using correlation regression tests.
Results: The mean mesiodistal width of the six maxillary anterior teeth was 52.97 (+2.29) mm, and the mean
distance of the interpterygomaxillary notch was 44.28 (+ 3.29) mm. The corelation and regression tests
showed that there was a stastically significant positive corelation (p=0.001), Pearson coefficient = 0.498
between the interpterygomaxillary notch distance and total mesiodistal width of the six maxillary anterior
teeth.
Conclusion: The majority of cases showed a significant relationship between the interpterygomaxillary
notch distance and total mesiodistal width of the six maxillary anterior teeth. Though other parameters
should also be considered to analyze and compare other morphological structures to improve the aesthetic
requirement for the conventional denture wearer.
