Bone graft and guided bone regeneration method
First Claim
1. An implantable, biocompatible osteogenic bone graft comprising a coherent mass of bone particles possessing at least one zone of impermeability to soft tissue ingrowth, said zone of impermeability being a porous region of the coherent mass of bone particles possessing pores having an average pore size which substantially prevents the ingrowth of bone tissue, wherein said zone is integral with the bone graft, such that the zone of impermeability and the bone graft are indivisibly connected so as to form a single unified whole.

Abstract
An implantable, biocompatible, osteogenic bone graft comprises at least one zone of impermeability to soft tissue ingrowth which is integral with the bone graft. Application of the bone graft to a bone repair site leads to selective rapid new bone ingrowth and inhibits or prevents soft tissue, e.g., gingival, epithelial, connective and/or muscle tissue, ingrowth in those areas adjacent to the zone(s) of impermeability to soft tissue ingrowth. The bone graft can be employed in a wide variety of bone repair procedures.
