Abstract
Implant devices for implantation within an intervertebral space are provided, together with methods and tools for use therewith. Implant devices of the present invention include an implant body formed of a synthetic bone substitute material, such as a nanocrystalline calcium phosphate material. The implant body and the methods and tools used therewith are configured to optimize strength and stability of the implant, minimize areas of stress concentration in the implant body and promote bone growth through the implant body and fusion of the vertebra.
