1. A method of reconstructing damaged facial skeletal features having a pre-damaged shape surrounded, at least in part, by undamaged bone, in a particular patient comprising:
- first, fabricating a first three-dimensional corporeal model of the surrounding portion of undamaged bone of a particular patient'"'"'s facial skeleton feature;
second, fabricating a second three-dimensional corporeal model of that section of the facial skeletal feature having the shape of the particular patient'"'"'s predamaged bone;
third, forming surgical mesh material having the shape of the particular patient'"'"'s pre-damaged skeletal features and joining the patient'"'"'s undamaged facial skeletal features using the joined first and second three-dimensional corporeal models as template for the surgical mesh material thereby forming a customized surgical implant for the patient;
fourth, placing donor bone at the site of the facial damaged skeletal feature; and
fifth, securing the customized surgical implant over the donor bone, and between the donor bone and the patient'"'"'s skin, thereby providing custom shaped structural support for the donor bone lying between the donor bone and the patient'"'"'s skin, and achieving a cosmetically acceptable replacement of the damaged facial skeletal feature using donor bone.

Abstract
A method of forming a surgical mesh material to be used in conjunction with donor bone in reconstructive surgery. A first corporeal model is made of the defect in the bone using computer tomographic techniques. The computer drives a sculpting tool. A second corporeal model is made of missing bone. Surgical mesh is shaped using the second corporeal model as a template. The shaped surgical mesh can be implanted in the patient.

9. A method of reconstructing damaged eye orbits surrounded, at least in part, by undamaged bone, in a particular patient comprising:
-
first, fabricating a first three dimensional corporeal model of the surrounding undamaged bone surrounding a damaged portion of a particular patient'"'"'s eye orbit; second, fabricating a second three dimensional corporeal model of the damaged portion of the eye orbit, the second model having the shape of the particular patient'"'"'s pre-damaged eye orbit; third, forming a first surgical mesh material having the shape of the back surface of the eye orbit or the particular patient'"'"'s pre-damaged bone using the second three-dimensional corporeal model as a template; fourth, forming a second surgical mesh material having the shape of the visible contour of the patient'"'"'s pre-damaged bone using the second three dimensional corporeal model as a template; fifth, securing the first surgical mesh at the site of the damaged eye orbit; sixth, placing donor bone over the first surgical mesh; and seventh, securing the second surgical mesh over the donor bone.
