Stress distribution & deflection in an Aramany class II obturator fabricated with cobalt-chromium & titanium alloys - 3D FEA.

Purpose/objectives: The aim of the research was to develop a model that accurately represents an Aramany class II defect and its obturator prostheses fabricated with Cobalt Chromium alloy & Titanium alloy to compare the deflection and the stress distribution in the rehabilitated area.

Methods: Aramany class II defect and the obturator prostheses was generated geometrically utilizing ANSYS 14.5, both overlaid on each other to impressionist prostheses and the maxilla as one element.
