Rapid prototyping (RP) applications have an increasing trend, making the future of RP more and more promising. These applications may include design, development, and manufacture of medical devices and instrumentation, as well as prosthesis design, anatomical modelling, surgical planning and prosthesis fabrication. This paper provides a new methodology for design of custom-made femoral stem, pr...

One of the modern trends in prosthetics and orthotics is production design covers for lower limb prostheses. Thanks to advantages CAD/CAM, there are no limits these covers. At present, companies that provide produced by additive manufacturing, but their price relatively high. In this work, motivation procedure an individual cover a prosthesis specific user discussed. The aim study propose metho...

INTRODUCTION The Triathlon(®) (Stryker, Kalamazoo, MI, US) total knee replacement was designed to improve patient function and survivorship. The aim of this study was to determine whether the Triathlon(®) prosthesis produces better patient reported outcomes than a previous design by the same manufacturer, the Kinemax Plus. METHODS The outcome of 233 knees of patients with a mean age of 68 yea...

The state-of-the-art porous coatings become more and more popular in uncemented prostheses to make bone grow into implants for biological fixation. In this paper, graded cellular structures are proposed for uncemented prostheses to enhance stability on implant-bone interfaces. As an example study, the authors develop a new acetabular implant with gradient porosity for hip replacement. A gradien...

BACKGROUND Loss of teeth affects the individual's health. Many factors determine the need to wear a removable dental prosthesis. Due to nature of design, age and lack of awareness, prosthesis often are neglected to maintain in an aseptic condition leading to microbial contamination. This provided an impetus for the present study with the aim of determining the microbial contamination of removab...
