Bioactive porous bone graft implants

Bioactive porous bone graft implants in various forms suitable for bone tissue regeneration and/or repair, as well as methods of use, are provided. The implants are formed of bioactive glass and have an engineered porosity. The implants may take the form of a putty, foam, fibrous cluster, fibrous matrix, granular matrix, or combinations thereof and allow for enhanced clinical results as well as ease of handling.
