Abstract
Abstract An implant for use in bone augmentation includes a hollow casing made of a resorbable material and a prosthetic filling material for bones contained within the casing. A method for bone augmentation includes the steps of making an incision adjacent to the augmentation site, inserting an implant comprising a hollow casing made of resorbable porous material and filled with a prosthetic filling material for bones, into the augmentation site directed via the incision, and closing the incision.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
67 words
An implant for use in alveolar above bone augmentation which provides a stress-bearing prosthesis, comprising: a hollow casing formed of a porous mesh, resorbable polyglycolic acid polymeric material; and hydroxylapatite prosthetic filling material particles contained within said casing, some of said particles protruding through said mesh casing wherein the porous mesh size is smaller than the mesh size of said particles to preclude escape of said particles.
Claim 2
Dependent Claim
67 words
