A method for treating a mandible including forming an initial digital 3D model of a mesh graft containment device (100) 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 (104), a lingual surface (106), a superior surface (108) and an inferior surface (110), individually adjusting one of the buccal surface and the lingual surface relative to a first midplane (A), which extends through a longitudinal axis (L) 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.
