Now what are accepted widely as implants may be dental implants or artificial tooth roots. However, what are referred to as implants here are orthopaedic implants including artificial joints and bone fixation devices placed within the human body. They are made from titanium alloy, stainless-steel, ceramics, Ultra High Molecular Weight Polyethylene etc.

These materials are used in combination based upon their physical properties including strength and abrasion quality.

Indications for use: They are intended for bone fixation in patients with fractures and the replacement of bones and joints in order to substitute their functions. Plates, screws and nails can be removed after the completion of bone fixation, while replacement prostheses including artificial joints and Artificial bone shafts will remain placed within the body until they fail to function.
