An allogenic implant for use in intervertebral fusion is formed from one or more two pieces. The pieces are made from bone, and are joined together to form an implant having sufficient strength and stability to maintain a desired distance between first and second vertebrae in a spinal fusion procedure. The implant pieces may be formed of cortical bone and connected by dovetail joints, and at least one cortical bone pin may be provided to lock the pieces together and to add strength to the implant. Teeth are formed on the vertebra engaging surfaces of the implant prevent short-term slippage of the implant.
