Advanced Surgical & Prosthetic Management of the Resorbed Maxilla

Treatment of the fully edentulous maxillary arch with moderate to severe resorption with a fixed implant restoration is a challenging treatment indication.

One alternative long available has been the utilization of bone grafting, including block grafts and sinus inlay grafting with either autogenous or allograft material to increase the dimension for posterior bone support for implant placement.

As an alternative to sinus inlay grafting, Per-Ingvar Brånemark introduced the zygomatic implant in the 1980’s.  The use of an implant with trans-sinus placement into the zygomatic buttress or arch demonstrating success equivalent to other endosseous implants has been confirmed by several investigators.  Early barriers to use of this implant were the surgical approach requiring direct visualization of the superior zygomatic arch and suboptimal prosthetic positioning of the implant head toward the palate.  In 2004 John Stella and Michael Warner introduced the sinus slot technique, which increased the potential for safety of placement and improved alignment without extensive dissection to allow direct visualization. The sinus slot technique also allows for placement with local anesthesia only.

In 2005, after learning the method from John Stella, Yvan Fortin further adapted the procedure to insert the implant apex in the superior maxilla, medial to the base of the zygoma.  This approach has more bone available for apical anchorage, while also providing for more posterior placement and ideal prosthetic orientation relative to the ridge crest. Dr. Brånemark has reviewed and approved this adaptation of his original protocol to be clinically sound.

The objectives of this course are:

To review the diagnosis of the severely resorbed posterior maxilla with surgical and restorative implications for implant placement.

To demonstrate alternatives to sinus inlay grafting utilizing tilted implants (15 year follow up) and trans-sinus implants anchored in the superior maxilla (4 year follow up) for both the fully edentulous maxilla and the posterior partially edentulous segment

To provide a live surgical demonstration of utilizing 40-45 mm long implants (zygomatic implants) anchored in the superior maxilla instead of the zygomatic buttress or arch for superior prosthetic positioning, followed by participant hands-on implant placement using models.

To allow participants to examine post-treatment patients with follow-up ranging from 1 to 5 years post-prosthesis delivery for radiographic, soft tissue inspection and restorative evaluation purposes.
