Aims and Objectives: The aim of this study was to observe the relationship between the width of permanent maxillary anterior teeth with the dimensions of hard palate for the selection of appropriate mesiodistal width of artificial maxillary anterior teeth. Materials and Methods: This study was conducted on seventy individuals within the age group of 18-30 years. Both upper and lower dental casts were made. All the measurements were taken directly on the maxillary dental casts with a precise digital calliper. In all the seventy individuals the significance of the differences in the means and the ratios of means of arch dimensions and tooth measurements were calculated. Results: No statistically significant difference was found between the interhamular width/ distal maxillary arch width and the sum of the widths of maxillary anterior teeth.(p>0.05 and t<1.96). Conclusions: Interhamular width and distal maxillary arch width were found to be almost equal to the sum total mesiodistal dimension of maxillary anterior teeth. But after extraction of all teeth, distal maxillary arch width is lost which is not possible to reconstruct because of different rate of alveolar bone resorption. On the other hand, Interhamular width remains of the same dimension during lifetime. Therefore it can be concluded that measurements of Interhamular width could be a practical method for clinical application, for determination of sum total mesiodistal width of maxillary anterior teeth.
