Mechanical requirements of implant materials
Dental implants must be able to sustain and transfer loads -It should have adequate mechanical strength in order to distribute the forces uniformly.
The modulus of elasticity of the implant material should be as close as that of bone in order to prevent peri-implant bone loss which occurs due to a phenomenon called stress-shielding. It is a phenomenon of loss of bone occurring as the result of removal of normal stress from the bone by an implant
