Background:
The aim of this paper is to underline the prosthodontics components features of two different overdenture retention systems on dental implants. The use of titanium, dental implants for replacing missing teeth is today considered to be a predictable procedure giving the patients esthetic and function for long time.
Methods:
Finite element analysis (FEA) and tests based on the Von Mises criterion have been applied in order to evaluate the stress distribution over two different prosthodontics retention systems. Two models with the ball attachment and with the Locator® systems have been created and put on simulated chewing stresses.
Results:
The two systems were subjected to axial and oblique forces and both guaranteed good results over simulated masticatory cycle. However, the Locator system seemed to better respond to the overall load distributions.
Conclusions:
Clinicians should choose the better prosthetic solution for the ridge they want to restore. Both retention systems offer long-term success if applied following the manufacture guide limitations and suggestions.

Stresses under Combined Loadings
The process begins by slicing the tube at critical points and analyzing the internal forces and stress components at these sections, focusing on the centroid. Normal stresses, generated by axial forces and bending moments, are either compressive or tensile and vary across the section from...
