The aim of this study was to measure mesiodistal width and shade of six anterior natural teeth of maxilla in a cross section of Central India population to act as a guide in restoration of anterior teeth in dentulous and edentulous patients. These readings were taken from 100 males and 100 females. The mean mesio-distal width and difference of each tooth on both side, combined mean mesio-distal width and difference of both side, most common shade of each tooth and difference of shade on both sides were estimated. It was observed that there is variation in mesiodistal width in right and left sides signifying that the anterior teeth are not mirror images of one another. Male subjects have greater mesiodistal width than females and right side dominates than left side. KEYWORDS: Mesiodistal width, anterior teeth, shade selection, artificial teeth.

ID-PVS and ID-PE was 0.02825 ± 0.0091, 0.01679 ± 0.0055, and 0.08442 ± 0.01516 mm, respectively. Statistically significant variation was found in mean dimensional accuracy in four groups. Conclusions: The dimensional accuracy of the casts obtained by pouring the impressions made by using direct technique were significantly more accurate as compared to the indirect technique.

Materials and methods: Forty impressions of the master model were made using direct technique with polyvinyl siloxane (Group D-PVS), and polyether (Group D-PE); and indirect technique with polyvinyl siloxane (Group ID-PVS), and polyether (Group IDPE), 10 impressions each. Specified dimensions of the resultant casts were measured using stereomicroscope with digital software. Mean actual cast error and subgroup’s actual cast error was calculated and statistically analyzed using Student Unpaired‘t’ test, ANOVA and Tukey Multiple comparison test. Results: The group’s mean actual cast error observed in Group D-PVS, D-PE. ID-PVS and ID-PE was 0.02825 ± 0.0091, 0.01679 ± 0.0055, and 0.08442 ± 0.01516 mm, respectively.
