[EO-8] Occlusal Distribution Between Conventional Metal Framework and Silicon-based Partially removable Dental Prosthesis: A Finite Element study
[Abstract]
Objective:
This study aimed to compare the occlusal stress distribution between Conventional Metal Framework and Polyamide on the abutment roots surface.
Method:
The study is composed of two dimensionally similar unilateral dental prosthesis made of Conventional Metal Framework (Cr.-Co) and thermoplastic resin (Polyamide) assembled on a missing lower first molar, and it is bounded by a 2nd premolar and 2nd molar abutment of the 4th quadrant. The components of the study such as the abutment tooth and prosthesis underwent a 3-D scan and converted to a STEP format, the values of component such as Young’s modulus and Possion’s ratio are inputted in the program to simulate the mechanical- physical properties of the Conventional Metal Framework, Polyamide, Natural tooth and Cortical bone to conduct the study as if it is done inside the oral cavity. A simulation was conducted, where a 350N load was applied on the prosthesis composed of the two different materials such as Metal framework and Polyamide. Stress surface distribution was registered and analyzed on the abutment roots via Finite Element Analysis Program in order to compare the two materials.
Results and Discussion:
It was concluded that there was a difference in the stress surface distribution on the abutment roots between Polyamide and Conventional Metal Framework dental prosthesis.
