Description Aim: The purpose of this research was to evaluate the behavior of the system locator settings associated with distal extension removable partial denture lower (PPR) by finite element analysis (FEA).
Materials and Methods: A Class II Kennedy 3D model using a CAD software Solid Works 2010 (SolidWorks Corp., Concord, MA, USA), and subsequently processed and analyzed by ANSYS Software version Model 14. One (1) was designed implant Tapered Screw -Vent® (ref TSVB10 Zimmer Dental-Carlsbad,CA,USA.) length x 10mm diameter 3.7mm with a 3.5mm platform, internal hexagon with its respective screw fixation; this was located at the tooth 37 as a rear pillar of a PPR, whose major connector was a lingual bar casting (alloy cobalt chromium), based combined (metal/ acrylic) with teeth to replace (37, 36 and 35). Efforts were evaluated von Mises in a 400N load. This analysis allowed assessing the performance of various prosthetic structures modeled and generated effects on bone-implant interface.
Results: Differences between the values von Mises in all structures and loads were observed before there was no permanent deformation in any of them. Structures such as bone showed in normal values microstrain.
Conclusions: The behavior of the PPRimplant connection, showed a favorable distribution efforts by using a PPR, subjecting it to load in the vertical direction.

Objetivo: El propósito de esta investigación fue evaluar el comportamiento del sistema de ajuste locator asociado con una prótesis parcial removible (PPR) con extensión distal inferior por medio del método de análisis de elementos finitos (MEF).
Materiales y Métodos: Se diseñó un modelo clase II Kennedy tridimensional utilizando un Software CAD de Solid Works 2010 (SolidWorks Corp., Concord, MA, USA), y posteriormente se procesó y analizó a través Software ANSYS versión 14. Se modelo un (1) implante Tapered Screw-Vent® (ref. TSVB10 Zimmer Dental-Carlsbad, CA, USA) de 10mm de longitud x 3.7mm de diámetro con una plataforma de 3.5mm, de hexágono interno con su respectivo tornillo de fijación; este se ubicó en el diente 37 como pilar posterior de una PPR, cuyo conector mayor fue una barra lingual colada (aleación cromo cobalto), con base combinada (metal/acrílico), con dientes a reemplazar (37, 36 y 35). Se evaluaron los esfuerzos von Mises en una carga 400N. Este análisis permitió valorar el comportamiento de las diferentes estructuras protésicas modeladas y los efectos generados en las interfases hueso-implante.
Resultados: Se observaron diferencias entre los valores von Mises en todas las estructuras y ante las cargas no hubo de-formaciones permanentes en ninguna de ellas. Estructuras como el hueso mostraron microdeformaciones en valores normales.
 Conclusiones: El comportamiento de la conexión PPR-implante, mostró una dis-tribución de esfuerzos favorable al utilizar una PPR, sometiéndola a carga en dirección vertical.
