Patient-specific mandible graft cage

Abstract

A method for treating a mandible including forming an initial digital 3D model of a mesh graft containment device based on dimensions of a target space of a mandible to be filled via the graft containment device, the 3D model of the graft containment device defined via a buccal surface, a lingual surface, a superior surface and an inferior surface, individually adjusting one of the buccal surface and the lingual surface relative to a first midplane, which extends through a longitudinal axis of the graft containment device between the buccal and lingual surfaces, to add or remove bulk along a desired portion of the 3D model of the graft containment device to form an adjusted 3D model, and forming a final graft containment device for placement in the target space of the mandible based on the adjusted 3D model.

1 - 14 . (canceled) 
     
     
         15 . A graft containment device for treating a mandible, comprising a mesh body extending along a longitudinal axis from a first end to a second end and including a channel extending therethrough along the longitudinal axis, the mesh body defined via a buccal surface, a lingual surface, a superior surface and an inferior surface, dimensions of the mesh body defined via dimensions of a target area of the mandible to be filled and a desired treatment plan for the mandible, one of a distance between and a relative position of the buccal and lingual surfaces of the mesh body selected to accommodate a portion of a dental implant therein without requiring additional prosthetic elements. 
     
     
         16 . The device of  claim 15 , wherein a distance between the superior and inferior surfaces of the mesh body is selected to reduce the risk of soft tissue irritation. 
     
     
         17 . The device of  claim 15 , wherein a pore size of the mesh body along at least a portion thereof is selected to accommodate a bone fixation element therethrough. 
     
     
         18 . The device of  claim 15 , further comprising a first fixation tab extending from at least one of the first and second end of the body along the buccal surface, the first fixation tab including an opening sized and shaped to receive a bone fixation element therethrough. 
     
     
         19 . The device of  claim 18 , further comprising a second fixation tab extending from at least one of the first and second end of the body along the inferior surface, the second fixation tab including an opening sized and shaped to receive a bone fixation element therethrough. 
     
     
         20 . The device of  claim 15 , wherein the mesh body is defined via a plurality of circumferential members and a plurality of longitudinal members intersecting one another.
