Treatment of the Severely Atrophic Arch With Zygomatic, Pterygoid, and Vomer Dental Implants

Dan Holtzclaw, DDS, MS

A 64-year-old man presented to the author's practice with hopes of replacing his maxillary denture. He had been wearing the denture for approximately 5 years and was told by other dentists that he had too much bone loss in the maxillary arch to accommodate implants. Using a variety of dental implants from Noris Medical (norismedical.com), the author was able to provide the patient with an immediately loaded fixed prosthetic solution that required no bone grafting. Noris Medical Pteryfit implants were bilaterally placed into the pterygomaxillary complex for terminal prosthetic support while a pair of Noris Medical Zygomatic implants were placed for mid-arch support. Anteriorly, support was achieved with a Noris Medical Tuff implant engaging the vomer. Noris Medical Tuff implants were also used to restore the mandible in a standard full-arch fashion. This case was immediately loaded and a final restoration was delivered 6 months after the initial surgery.

Key Takeaways

Noris Medical Pteryfit implants are specifically designed to engage the pterygomaxillary complex
and allow for immediate loading protocols.

Noris Medical Zygomatic implants have a unique design especially suited for extra-sinus surgical approaches.
The aggressive rough surfaced end cutting tip and smooth mid-coronal shaft make the implant an ideal fixture for treating cases with severe maxillary bone loss.

The Noris Medical line of dental implants is particularly suited for treatment of cases with severe bone loss. Also, with 0-, 17-, 30-, 45-, 52-, and 60-degree abutments, Noris Medical offers a wide selection of prosthetic platforms.
