Summary

The aim of this study was making a 3D modeling with the morphological characteristics of a first premolar from its morphometry. With reference to an anatomical diagram of a first upper premolar and morphometric relationships, it performs its contour plot (software Catya) considering at least three cross-sections of the figure seen occlusal, mesial-distal (AP) and one vestibulo- palatal (L). 2d obtained model is completed by extrapolation to obtain a three-dimensional mesh which subsequently transforms triangu- lar elements premolar model being ready to be imported into the software of the finite element analysis (Ansys) where these elements are transformed into the once plate elements connected by beams which gives a linear and isometric to which also inputs values of mechanical properties for each tissue for the analysis. Thus the figure obtained allows us to reproduce the morphology of the premolar and the relationships among its components, including linearity and isometry conferred allows us to study the mechanical behavior in any section of the model. Computational design of anatomical structures from a contour drawing based on their morphology and morphometry using the technique described results in a complementary alternative to study the morphology and mechanical analyzes of teeth or other anatomical structures.
