Abstract:
A method for producing bone grafts using 3-D printing is employed using a 3-D image of a graft location to produce a 3-D model of the graft. This is printed using a 3-D printer and a printing medium that produces a porous, biocompatible, biodegradable material that is conducive to osteoinduction. For example, the printing medium may be PCL, PLLA, PGLA, or another approved biocompatible polymer. In addition such a method may be useful for cosmetic surgeries, reconstructive surgeries, and various techniques required by such procedures. Once the graft is placed, natural bone gradually replaces the graft.

Claim (Index 1):
A method for producing a custom bone graft, comprising:\n obtaining a three-dimensional image of an intended graft location; creating a three-dimensional mesh using said three-dimensional image, wherein said created three-dimensional mesh serves as a supporting scaffold for said custom bone graft; creating a three-dimensional digital model of said custom bone graft using said three-dimensional image; creating a printing medium, wherein said printing medium comprises a mixture of a precursor powder and a precursor liquid in a predetermined ratio, and wherein a slow reabsorbing biocompatible, bioactive adhesive is added to said printing medium for improving fixation of said custom bone graft at said intended graft location; creating, by a three-dimensional printer, said custom bone graft, using said three-dimensional digital model and said printing medium, wherein said printing medium is deposited layer by layer, wherein after printing a pre-determined number of layers, the print axis is one of rotated and side-stepped before printing next set of pre-determined number of layers, wherein said rotation and sidestepping processes promote maximum vascular and neural growth within said created custom bone graft, wherein said creation of said custom bone graft is performed in a sterile environment comprising:\n a sterile disposable print surface; \n a sterile syringe for injecting said printing medium; \n a hood enclosing said three-dimensional printer, wherein said hood is coupled to a medical grade high efficiency particulate air filter, and wherein sterile air is drawn into said hood via said high efficiency particulate air filter and removed via a surgical-type suction connection; and \n wherein said sterile custom bone graft is adapted for direct insertion at said intended graft location without additional sterilization procedure.
