Abstract
An implant and process for manufacturing the implant for a joint of a patient comprises determining a dimension of a bone in the joint, generating a three-dimensional image of the bone, converting the image into a CAD model, determining a three-dimensional design for the implant according to the dimension of the bone, activating an electron beam melter, and additive-manufacturing the implant with the electron beam melter, the implant having a dimension equal to the dimension of the bone, the implant comprising a porous material. The porous material can be an osteoconductive material or an osteoinductive material or a combination thereof.
Claims10
A process for manufacturing an implant for a joint of a patient comprising:
- determining a dimension of a bone in the joint;
- generating a three-dimensional image of the bone;
- convening the image into a CAD model;

- and
- additive-manufacturing the implant with the electron beam melter, the implant having a dimension equal to the dimension of the bone, the implant comprising a porous material.
A process for manufacturing an implant for a joint of a patient, the process comprising:
- determining a dimension of a bone in the joint, said dimension being a dimension of an anterior face of the bone and a curvature of the neck of the bone and a total volume of an amount of the bone and a total volume of the an amount of the bone equal to 25% of the anterior face of the bone;
- generating a three-dimensional image of the bone;
- converting the image into a CAD model;
- determining a three-dimensional design for the implant according to the dimension of the bone;
- activating an electron beam melter;
- and
- additive-manufacturing the implant with the electron beam inciter, the implant having a dimension equal to the dimension of the bone, the implant comprising a porous material.
A process for manufacturing an implant for a joint of a patient, the process comprising:
- determining a dimension of a bone in the joint, the bone being a glenoid;
- generating a three-dimensional image of the bone;
- converting the image into a CAD model;
- determining a three-dimensional design for the implant according to the dimension of the bone, wherein the step of determining the three-dimensional design comprises:
- determining a force crossing 25% of an anterior of the bone;
- determining a distribution of forces of the implant by a finite element analysis, wherein the step of determining the distribution of forces comprises:
- calculating a density of cancellous bone at the face of the bone;
- and
- determining a normal humeral translational moment;
- and
- determining an area of potential failure of the implant;
- activating an electron beam melter;
- and
- additive-manufacturing the implant with the electron beam melter, the implant having a dimension equal to the dimension of the bone, the implant being a porous material.
