SINUS ELEVATION VIA SMALL FENESTRATION

(Clinical case provided by Dr. H. Jambrec, Geneva, Switzerland)

PRE-OP

X-ray showing a bone height of 4mm, which is not enough to place an implant.

SURGERY

After preparing the flap, a small fenestration (size ~8mm) was made to access the sinus.

Mixing of THE GRAFT (granules 1-2mm / 3.6 cc) with blood.

Filling of tube with xenograft.

Filling of sinus cavity.

Fenestration covered with very small pericardium membrane (SMARTBRANE mini, size: 10 x 10 mm).

6 MONTH POST-OP

Bone height of around 14mm was achieved.

HISTOLOGICAL PICTURE

Higher magnification image showing vital bone completely surrounding the graft material. The bone marrow is well vascularized with sparse lymphocytes in places.*

20 MONTH POST-OP

Situation 20 months after grafting procedure. Implant seems well integrated and bone height looks stable.
