Abstract

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.
