Influence of PEEK Coating on Hip Implant Stress Shielding: A Finite Element Analysis
Stress shielding is a well-known failure factor in hip implants. This work proposes a design concept for hip implants, using a combination of metallic stem with a polymer coating (polyether ether ketone (PEEK)). The proposed design concept is simulated using titanium alloy stems and PEEK coatings with thicknesses varying from 100 to 400 μm. The Finite Element analysis of the cancellous bone sur...
متن کاملEffect of Coating Materials on the Fatigue Behavior of Hip Implants: A Three-dimensional Finite Element Analysis
This study aims to validate, using finite element analysis (FEA), the design concept by comparing the fatigue behavior of hip implant stems coated with composite (carbon/PEEK) and polymeric (PEEK) coating materials corresponding to different human activities: standing up, normal walking and climbing stairs under dynamic loadings to find out which of all these models have a better performance in...
متن کاملinfluence of implant position on stress distribution in implant-assisted distal extension removable partial dentures: a 3d finite element analysis.
distal extension removable partial denture is a prosthesis with lack of distal dental support with a 13-fold difference in resiliency between the mucosa and the periodontal ligament, resulting in leverage during compression forces. it may be potentially destructive to the abutments and the surrounding tissues. the aim of this study was to assess the effect of implant location on stress distribu...
متن کاملFinite Element Analysis of Different Hip Implant Designs along with Femur under Static Loading Conditions
Background: The hip joint is the largest joint after the knee, which gives stability to the whole human structure. The hip joint consists of a femoral head which articulates with the acetabulum. Due to age and wear between the joints, these joints need to be replaced with implants which can function just as a natural joint. Since the early 19th century, the hip joint arthroplasty has evolved, a...
متن کاملInfluence of Orbital Implant Length and Diameter on Stress Distribution: A Finite Element Analysis
PURPOSE A mathematical simulation of stress distribution around orbital implants was used to determine which length and diameter of implants would be best to dissipate stress. METHODS An integrated system for computed tomography data was utilized to create a 3-dimensional model of craniofacial structures. The model simulated implants placed in the 7, 11, and 12 o'clock positions of the orbita...
