A finite element evaluation of stud type overdenture attachments
Sandu, Liliana/Topala, Florin/Porojan, Sorin/Bortun, Cristina Maria
The aim of the study was to evaluate the influence of the stud attachments components dimensions on their strength using the finite element analysis.Purposely designed resilient ball and socket stud type attachments were modeled in order to be exported for numerical simulations. The parameters like ball diameter and female insert width were varied. Generated stresses and displacements were calculated numerically and plotted graphically. High stresses were present on the upper surface of the resilient female insert. Regarding the stresses in the metal ball, they are present around the neck and on their top.
In the metal housing high stresses were located around the balls greatest circumference. The described methods can generate experimental models, which can be used to select the preferable attachment size.

Keywords: finite element analysis, stud type attachments, stresses
