Assessment of Removable Partial Dentures Using Finite Elements Analysis
Journal Title: Medicine in Evolution - Year 2017, Vol 0, Issue 4
Abstract
Aim and objectives. This study is focused on finite element analysis to dynamic load due to the action of the forces which operate in case of removable partial dentures and aims at making predictions about the areas with highest fracture risk. Material and methods. An upper class I Kennedy edentation with the fixed component represented by semi-physiognomic crowns on 2.4, 2.5, 1.4, 1.5 teeth and the mobile component made of two saddles and a palatinal connector, joined by precission millings and interlocks was taken in consideration. For the manufacture of the metallic framework Herenium Sun (Heraeus Kulzer) Co-Cr alloy was used. The Autodesk® Inventor® Professional software was used for visualisation, simulation and digital representation. Results. When a static load is applied at saddle level, the main stress appears at the joining areas of the metallic saddles with the interlocks and at the distal extremity of the main connector. A frequency of the load higher than 9535.17 Hz, applied at saddle level leads to fracture. Conclusions. Finite element analysis permits noninvasive testing in dental technique. The software enables the dental technician to import scannings of any prosthetic piece so the future resistance may be determined since the pattern stage.
