Resumo
The objective of this study was to evaluate comparatively dimensions of natural upper anterior teeth with artificial teeth of three trademarks Premium PalaTM (Heraeus Kulzer), SR Vivodent PETM (Ivoclar Vivadent), TriluxTM (VIPI), in order to identify models of artificial teeth that best reproduce the dimensions present in the natural human dentition in both genders. For measurements of natural teeth were used 96 dental casts arising from people of both genders, in which molding of the upper arch was performed to obtain study models for the purpose of performing dental measure using a digital caliper: width (LIC) and length (CIC) of the upper central incisor teeth obtained by averaging 11 and 21; and width of maxillary anterior teeth straight (LR) obtained by the sum of the individual widths of the upper anterior teeth. Additionally the width was measured from the upper anterior teeth in curve (LC), obtained with flexible ruler positioned on the buccal region of greatest volume between the distal surfaces of the upper canines and sustained in the buccal region of greatest volume of teeth. Corresponding measures of artificial teeth were obtained based on the values described in the template letter provided by the manufacturers. Comparisons between genders were carried out by the t test (α = 0.05) and absolute frequencies were used to tabulate and compare measures of natural and artificial teeth. Out of the 96 volunteers, 41 were male and 55 were female, with an average age between 22.5 and 21.8 years, respectively, without statistically significant differences (p> 0.05). All measurements were performed statistically different between genders (p <0.05), with higher values for male. Most models of artificial and natural teeth presented LIC in the range between 8.0 to 8.5 mm. As for CIC, most volunteers is between 10.6 to 11.0 mm, while most models of artificial teeth is between 9.6 to 10.0 mm. Most models of artificial teeth and volunteers have LR between 46-47 mm. Only the letter template of teeth TriluxTM provides the LC measure, with most models between 50-51 mm. Yet most volunteers are between 54-55 mm. It can be concluded that the trademarks of artificial teeth evaluated feature models with width measurements compatible with natural teeth; however, the length of the upper central incisor is about 0.5 to 1.5 mm smaller than that observed in the majority of volunteers. There are models of artificial teeth that present CIC and LC with non-existent measures in the population studied.
