Against All Odds A “No Bone Solution™” continues:

Following the guided portion of the surgery, which assisted in the placement of 5 Brånemark implants, the surgical template was removed. A crestal incision and vertical releasing incisions were made bilaterally and full thickness flaps were elevated to the level of the superior aspect of the zygomatic bone. The transantral osteotomies, using graduated diameter drills, were completed to permit the apex of the implants to penetrate through the lateral surface of the zygoma. A total of four Brånemark System® Zygoma implants were installed—two in each zygoma. Finally, using the Teeth In A Day® conversion protocol, the previously constructed prosthesis was installed on the standard Brånemark implants and then connected intraorally to the zygomatic implants. The prosthesis was then removed, adjusted, polished and reinstalled.

The Final Prosthesis:
Osseointegration, under immediate loading conditions is paramount to the success of this prosthesis. Research on immediate loading has shown that after eight weeks–osseointegration should be mature to allow for a predictable outcome.1 Due to this patient’s numerous medical conditions, the final impression was taken after a 12-week healing time. He was restored using CM ceramic technology produced in Mahwah, New Jersey.
The final prosthesis for the maxilla consisted of a CAD/CAM robotically milled titanium frame with individual zirconium ceramic crowns using the Nobel Biocare Procera Technology. (Figs 5A, 5B, 5C)
