γGamma-BSM® Moldable Putty

Moldable Bone Substitute Material

Sets Hard
High Strength
Cell-Mediated Remodeling

Etex’s γGamma-BSM® Moldable Putty meets the need for hard setting, high compressive strength materials that are implantable in a wet environment.

γGamma-BSM® Moldable Putty is engineered using proprietary nanocrystalline calcium phosphate technology and undergoes cell-mediated remodeling1,2.
