An intervertebral implant for being implanted between adjacent vertebrae is provided. The implant includes a generally elongate implant body having a length extending between opposite longitudinal ends thereof, a superior face and an inferior face. The superior face and inferior face include cortical teeth adjacent to the implant body longitudinal ends. Additionally, the superior and inferior faces include longitudinally central teeth intermediate the cortical teeth and have bone engaging ends. The central teeth have a sharper configuration than that of the cortical teeth bone engaging ends for biting into the softer central bone material of the vertebrae. The cortical teeth are arranged in a first density per unit area and the central teeth are arranged in a second density per unit area that is less than the first density.

The production of bioceramic powders and bioceramic implants are described and an additive manufactured implant used for tissue reconstruction and a method for manufacturing the implant are disclosed. The implant may be fabricated at least in part from suitable bioceramic powders produced using tailored mineral compositions tailored to the unique material properties of the tissue being replaced. The implants may be tailored to a three-dimensional shape and mechanical properties of the tissue defect designed to be replaced by surgical implantation of the device. Native tissue repair and regeneration at the site of implantation are also provided.

The invention relates to components for fusing vertebral bodies and to methods for the production and use thereof.

Methods and devices are disclosed for treating the vertebral column. An implant for treating the spine is provided comprising at least two articulations between the spacer and the bone facing surface of the fixation plate. Another implant for treating the spine is also provided, comprising two or more fixation plates attached to a spacer with two or more articulations, wherein the fixation plates are independently movable.

A medical use honeycomb structure having a plurality of through-holes extending in one direction, wherein an outer peripheral section of the medical use honeycomb structure has a through-hole groove formed by incomplete side walls of the through-hole, and a through-hole inlet adjacent to the through-hole groove.
