Orthopedic titanium implants such as bone screws have been widely used for some decades in the treatment of acute and degenerative bone and joint defects affecting millions of people worldwide.
Bioresorbable phosphate glass fibre reinforced polyester composites have been investigated as replacement for some traditional metallic orthopaedic implants, such as bone fracture fixation plates.
Since that time, numerous otologists have reported success with mastoid obliteration techniques, using alloplastic materials as well as various biogenic implants, such as fat, cartilage, bone pate, bone chips, ceramic powder, Ceravital, and hydroxyapatite [ 163– 163].
This new class of collagen-based hybrid DN gels, as soft and elastic ceramics, having good biomechanical performance and strong bonding ability with bone would expand the choice for designing next-generation orthopedic implants such as artificial cartilage, bone defect repair material in the load-bearing region of the body.
Additionally, like a ski binding, the mechanism releases to prevent damage to the bone or implant, such as during a fall.
The use of porous materials has been investigated for several decades and has been integrated into areas of orthopaedic implants, such as dental and bone (joint) implants.
With 3-D printing it's possible to integrate useful functionality into implants, such as porous structures that enhance bone ingrowth and adhesion, and to also produce new devices that would be difficult or impossible to make conventionally.
The compromising biomechanical changes in rheumatic bone could increase the risk of mechanical complications in cementless implants, such as peri-prosthetic fractures, insufficient initial implant stability and insufficient osseous integration causing early implant failure.
It is also biocompatible, and so could be used to make medical implants such as screws to hold together mending bones, or artificial blood vessels.
