An Introduction of New Artificial Bone Unit “Tetra-Bone”

Abstract

We fabricated a small α-TCP ceramic unit having four pods, named “Tetra-bone” employing a ceramic injection molding. Tetra-bone can keep uniform concave geometry among the pods as well as immobilizing each other. Owing to the monotony of Tetra-bone, weight of Tetrabones used can be converted into the number of Tetra-bones, volume that can be filled with Tetrabones, and the number of functional structures. By using Tetra-bones, bone defects can be filled with intentional geometry that helps to discuss the relation between geometric features of pores and bone formation.

Histochemical and Radiological Study of Bone Regeneration by the Combinatorial Use of Tetrapod-Shaped Artificial Bone and Collagen

“…Previously, tetrapod-shaped -tricalcium phosphate (TCP) granules, Tetrabone (TB) had developed as a novel artificial bone 8,9) . TB possesses four armed structures that enable the formation of inter-granular spaces, which facilitate the migration of cells and blood vessels 10) .…”
