ii) engaging said superior side of said surgical cavity with said custom fitted implant; and

iii) engaging said inferior side of said surgical cavity with said custom fitted implant; and

e) packing said custom fitted implant with osteogenic material after said custom fitted implant is inserted into said surgical cavity; or

f) after insertion of said custom fitted implant into said surgical cavity, but prior to packing said custom fitted implant with osteogenic material, removing said custom fitted implant from said surgical cavity for packing said custom fitted implant with osteogenic material, and thereafter, reinserting said custom fitted implant packed with osteogenic material into said surgical cavity.

9. The method of claim 8 , wherein said step of sizing said implant for a custom fit for said surgical cavity by severing said implant through at least one cross-section thereof creates:
