Abstract
When implants are incorporated into an existing partial removable dental prosthesis, the acrylic resin base can fracture. It is therefore essential to study the mechanical behavior of partial removable dental prostheses by using stress and deformation analysis.

It is therefore essential to study the mechanical behavior of partial removable dental prostheses by using stress and deformation analysis.</AbstractText><AbstractText Label="PURPOSE" NlmCategory="OBJECTIVE">The purpose of this study was to analyze the effect of the occlusal rest position on the implant-assisted partial removable dental prosthesis by finite element analysis.</AbstractText><AbstractText Label="MATERIAL AND METHODS" NlmCategory="METHODS">A Faro Arm scan was used to extract the geometrical data of a human partially edentulous mandible. A standard plus regular neck (4.8×12 mm) implant and titanium matrix, tooth roots, and periodontal ligaments were modeled by using a combination of reverse engineering in Rapidform XOR2 and solid modeling with the Solid Works CAD program. The model incorporated a partial removable dental prosthesis and was loaded with standard bilateral forces. A uniform pressure was applied on the occlusal surface so as to generate an equivalent net force of 120 N for both the left and right prosthesis. The finite element analysis program ANSYS Workbench was used to analyze the stress and strain distributions in the implant-assisted partial removable dental prosthesis.</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">Maximum stresses were significantly high for the metal framework compared to the acrylic resin surface, and these stresses were different for the mesial and distal arm designs. The maximum stress in the metal framework for the mesial arm design was 614.9 MPa, and it was 796.4 MPa for the distal arm design. The corresponding stresses in the acrylic resin surface were 10.6 and 8.6 MPa.</AbstractText><AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS">Within the limitation of this study, it was found that moving the position of the occlusal rest from the mesial to distal side of the abutment teeth improved the stress distribution in the metal framework and acrylic resin denture base structures.</AbstractText><CopyrightInformation>Copyright © 2014 Editorial Council for the Journal of Prosthetic Dentistry.
