Fidelidade anatômica de dentes artificiais de estoque:análise comparativa com dentes naturais

Abstract

This study evaluated the anatomical fidelity of stock artificial teeth in comparison with the morphological patterns of natural teeth described in classical literature. A total of four commercial brands of artificial teeth were analyzed, considering aspects related to the direction of dental surfaces, crown dimensions, tooth diameters, intra-group proportions, and number of cusps. The methodology consisted of a morphological comparison between the artificial models and the anatomical parameters described in the dental literature. The results demonstrated greater anatomical conformity in the Ivoclar brand, while the Biotone and New Ace brands showed higher rates of divergence, mainly regarding the horizontal convergence of dental surfaces. It was observed that all brands maintained conformity regarding the number of cusps. It was concluded that there are relevant morphological discrepancies between artificial and natural teeth, especially related to horizontal crown proportions, which may negatively influence esthetics and prosthetic function. The study highlights the importance of careful anatomical analysis in the selection of artificial teeth for prosthetic rehabilitations, aiming at better functional and esthetic outcomes.
