Abstract
A cranial implant molding device having a frame or base that receives a bottom or convex molding plate and a top or concave molding plate in a manner whereby the two plates are separated a distance to receive a settable or curable implant forming material therebetween. The plates are separated by a compressible member such that by the use of threaded mechanical fasteners or similar members the distance between the two plates can be adjusted by tightening or loosening the mechanical members. The thickness of the implant is varied by varying the separation distance on different sides of the frame.
Claims11
A cranial implant molding device comprising:
- a bottom plate comprising a mold cavity bottom wall, a first and a second bottom plate flange positioned to either side of said mold cavity bottom wall, and a depending wall connecting each of said bottom plate flanges to said mold cavity bottom wall;
- a top plate comprising a mold cavity top wall, a first and a second top plate flange positioned to either side of said mold cavity top wall, a depending wall connecting each of said top plate flanges to said mold cavity top wall, and a vent port disposed in said mold cavity top wall;
- a base comprising a recess, said bottom plate and said top plate being positioned on said base such that said mold cavity bottom wall and said mold cavity top wall are disposed within said recess and such that said mold cavity bottom wall is separated from said mold cavity top wall to form a mold cavity adapted to receive implant forming material;
- at least one mechanical adjustment member extending through said first top plate flange and said first bottom plate flange and into said base, and at least one other mechanical adjustment member extending through said second top plate flange and said second bottom plate flange and into said base, whereby manipulation of said mechanical adjustment members adjusts the distance between said first top plate flange and said first bottom plate flange and between said second top plate flange and said second bottom plate flange, thereby adjusting the distance between said mold cavity top wall and said mold cavity bottom wall.

A cranial implant molding device comprising:
- a bottom plate comprising a generally convex mold cavity bottom wall, a first and a second bottom plate flange positioned to either side of said mold cavity bottom wall, and a depending wall connecting each of said bottom plate flanges to said mold cavity bottom wall;
- a top plate comprising a generally concave mold cavity top wall, a first and a second top plate flange positioned to either side of said mold cavity top wall, a depending wall connecting each of said top plate flanges to said mold cavity top wall, and a vent port disposed in said mold cavity top wall;
- a base comprising a recess, said bottom plate and said top plate being positioned on said base such that said mold cavity bottom wall and said mold cavity top wall are disposed within said recess and such that said mold cavity bottom wall is separated from said mold cavity top wall to form a mold cavity adapted to receive implant forming material;
- at least one compressible resilient member disposed between said first top plate flange and said first bottom plate flange, and at least one resilient member disposed between said second top plate flange and said second bottom plate flange;
- at least one mechanical adjustment member extending through said first top plate flange and said first bottom plate flange and into said base, and at least one other mechanical adjustment member extending through said second top plate flange and said second bottom plate flange and into said base, whereby manipulation of said mechanical adjustment members adjusts the distance between said first top plate flange and said first bottom plate flange and between said second top plate flange and said second bottom plate flange, thereby adjusting the distance between said mold cavity top wall and said mold cavity bottom wall;
- wherein said mechanical adjustment members may be independently manipulated, such that the distance between said first top plate flange and said first bottom plate flange may be different from the distance between said second top plate flange and said second bottom plate flange.
