Behavior of the peri-implant tissue following a dental implant surgery is simulated. The cascade of tissue responses starting with healing, followed by remodeling are investigated. Although different implant designs, implant widths and amounts of micro-motion during the healing period were all shown to have important effects on the long-term status of the surrounding region; the amount of micro-motion...
Detachment of greater trochanter (GT) is generally associated with hip arthroplasty complications and needs for repositioning and fixation. A new GT reattachment system (Y3) was proposed to reduce GT displacements in anterior-posterior direction to decrease non-union issues. The goal of this study is to develop and validate a FEM of the Y3 GTR system. FEM validation suggests a good concordance between...
A quantitative assessment of femur stress under compression and bending condition is essential for the understanding of failure mechanisms and providing guidance for the design and operation of femur replacement. The stress distribution of femur under bending moment and compressive load is simulated using finite element method (FEM) in this paper. A two-dimensional FEM model is established according...
The phenomenon of bone remodeling is a complex biological process which is dependent on genetic, hormonal, metabolic and age-related. Being familiar with the mechanisms of bone remodeling is of great importance for implant design and metabolic diseases such as osteoporosis, since it enables monitoring of bone tissue. The bone remodeling phenomenon can be described mathematically and simulated in a...
