Sinus Augmentation With Dental Implant

An Open Label, Non Randomized, Single Arm, Multi Center Study to Assess Sinus Augmentation (Sinus Lift) Utilizing INFUSE® Bone Graft Concurrent With Dental Implant Placement

The purpose of this research study is to shorten the treatment time course for patients who are scheduled for surgery to have a sinus lift and dental implant(s) placed into the upper front part of their mouth, and need to have more bone in their jaws and a thicker sinus floor to support the implant.

The INFUSE® Bone Graft is a device approved by the FDA to be used instead of using your own bone (from another site on your body) to replace missing bone in your jaw. INFUSE® Bone Graft is commercially available and is made up of 2 parts - recombinant human Bone Morphogenetic Protein-2 (rhBMP 2) placed on an absorbable collagen sponge (ACS). The rhBMP-2 is a genetically altered protein which recruits bone-forming cells to the surgical area and changes local cells to bone. ACS is made from Type I collagen from bovine (cattle) tendon. It helps to hold the rhBMP-2 in place and acts as a support for the growing bone. The sponge itself will reabsorb in time as the new bone forms.

The purpose of this research study is to shorten the treatment time course for the patients. This post-market study has been designed to further evaluate the effectiveness and safety of INFUSE® Bone Graft, along with dental implant placement and a sinus lift, in a single procedure.

Inclusion Criteria:

5. Active infection at operative site
6. History of prior exposure to rhBMP-2/ACS
7. Received and failed a previous sinus augmentation procedure
8. Pathology that would either compromise a bone grafting procedure, or interfere with obtaining quantitative measurements from postoperative computer tomography scans
9. Significant untreated periodontal disease (> Grade 3), caries, or chronic inflammation of the oral cavity at operative site
10. Active use of any nicotine-containing products such as, but not limited to, smoking and chewing tobacco, nicotine patch, nicotine gum, etc.
