Advanced Surgical and Prosthetic Management of the Resorbed Maxilla
Treatment of the fully edentulous maxillary arch with moderate tosevere resorption with a fixed implant restoration is a challenging treatmentindication.
One alternative long available has been the utilization of bonegrafting, including block grafts and sinus inlay grafting with eitherautogenous or allograft material to increase the dimension for posterior bonesupport for implant placement.
As an alternative to sinus inlay grafting, Per-Ingvar Brånemarkintroduced the zygomatic implant in the 1980’s. The use of an implant with trans-sinus placement into thezygomatic buttress or arch demonstrating success equivalent to other endosseousimplants has been confirmed by several investigators. Early barriers to use of this implant were the surgicalapproach requiring direct visualization of the superior zygomatic arch andsuboptimal prosthetic positioning of the implant head toward the palate. In 2004 John Stella and Michael Warnerintroduced the sinus slot technique, which increased the potential for safetyof placement and improved alignment without extensive dissection to allowdirect visualization. The sinusslot technique also allows for placement with local anesthesia only.
In 2005, after learning the method from John Stella, Yvan Fortinfurther adapted the procedure to insert the implant apex in the superiormaxilla, 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 prostheticorientation relative to the ridge crest. Dr. Brånemark has reviewed and approved this adaptation of his originalprotocol to be clinically sound.
The objectives of this course are:
To review the diagnosis of the severely resorbed posterior maxillawith surgical and restorative implications for implant placement.
To demonstrate alternatives to sinus inlay grafting utilizing tiltedimplants (15 year follow up) and trans-sinus implants anchored in the superiormaxilla (4 year follow up) for both the fully edentulous maxilla and theposterior partially edentulous segment
To provide a live surgical demonstration of utilizing 40-45 mm longimplants (zygomatic implants) anchored in the superior maxilla instead of thezygomatic buttress or arch for superior prosthetic positioning, followed byparticipant hands-on implant placement using models.
To allow participants to examine post-treatment patients withfollow-up ranging from 1 to 5 years post-prosthesis delivery for radiographic,soft tissue inspection and restorative evaluation purposes.
