Abstract
A method of forming an implant having a porous region replicated from scanned bone, the method comprising imaging bone with a high resolution digital scanner to generate a three-dimensional design model of the bone; removing a three-dimensional section from the design model; fabricating a porous region on a digital representation of the implant by replacing a solid portion of the digital implant with the section removed from the digital representation; and using an additive manufacturing technique to create a physical implant including the fabricated porous region.
Claims15
A method of forming an implant having a porous region replicated from scanned bone, the method comprising the steps of:
- imaging bone with a high resolution digital scanner to generate a three-dimensional design model of the bone;
- removing a three-dimensional section from the design model;
- fabricating a porous region on a digital representation of the implant by replacing a solid portion of the digital implant with the section removed from the design model;
- and
- using an additive manufacturing technique to create a physical implant including the fabricated porous region.
A method of forming an implant having a porous region replicated from scanned bone, the method comprising the steps of:
- creating a digital image of the bone with a microCT scanner;
- removing any defective artifacts from the digital image;
- converting the digital image to a three-dimensional design model of the bone;
- removing a three-dimensional section that structurally replicates the architecture of the bone from the design model;
- printing the removed design model section on a digital representation of the implant;
- and
- creating a physical implant from the printed digital representation by using an additive manufacturing technique.
A method of forming an implant from scanned bone to fill a bone void, the method comprising the steps of:
- imaging a voided bone region with a high resolution digital scanner to generate a three dimensional design model of the voided bone region;
- providing a digital representation of a non-voided bone region;
- removing a three dimensional section of the non-voided bone region, the removed section having a size that substantially matches the size of the voided bone region;
- and
- creating a physical implant from the removed three dimensional section of the non-voided bone region by using an additive manufacturing technique, the implant being configured to be installed within the voided bone region.
