Biomechanical properties of hip implant with ceramics coating

Finite 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...

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...

Ion-Doped Silicate Bioceramic Coating of Ti-Based Implant

Titanium and its alloy are known as important load-bearing biomaterials. The major drawbacks of these metals are fibrous formation and low corrosion rate after implantation. The surface modification of biomedical implants through various methods such as plasma spray improves their osseointegration and clinical lifetime. Different materials have been already used as coatings on biomedical implan...

Model-based biomechanical dental implant optimization in bone- implant system

Purpose: The purpose of this study was to identify the important parameters for a model-based design optimization method through comparison of different biomechanical environments and various dental implant models. Materials and Methods: Finite element analysis (FEA) was applied to model a mandibular bone implant system. Essential parameters, such as, cortical bone properties, boundary conditio...
