Improving Characteristics of Overdenture Attachments with the Use of Numerical Simulation

The objective of this study was to validate the Numerical Simulation Model proposed for Locator (Zest Anchors, Inc.) system, by comparing the retention values with the ones mentioned in the product catalogue in order to optimise the shape of the overdenture systems, to improve the component properties and to study the impact of certain parameters upon the functionality. The use of numerical simulation is useful to test several constructive versions with relatively low cost. By using this method, the design is carried out in a virtual environment, and the high costs involved in prototypes testing are eliminated. The Finite Element Model designed for Locator system and the assigned properties leading to simulated retention force values close to those given in the Straumann catalog, demonstrate that the numerical simulation properly surprised the physical phenomena and it may be used for retention system optimization.
