NobelZygoma – a graftless solution

For patients with severe maxillary resorption, extensive grafting procedures can mean lengthy treatment times. But there is an alternative.

By anchoring in the zygomatic bone, the NobelZygoma implant system can enable an immediate loading protocol for a graftless treatment. It also offers a broad choice of prosthetic options. This dramatically shortens time-to-teeth for increased patient satisfaction, and allows patients with severely resorbed maxillae to return to a normal quality of life.1

The Zygoma implant helps increase patient treatment acceptance by eliminating grafting. Patients benefit from a less invasive procedure and immediate rehabilitation.

High primary stability for Immediate Function

Nobel Biocare’s zygomatic implants are designed to achieve high primary stability.2 This allows patients with severe bone loss to have a fixed provisional prosthesis fitted immediately after surgery, avoiding the average nine-month wait and multiple surgeries required with grafting. Immediate Function with zygomatic implants has other benefits besides shorter treatment time, such as fewer clinical visits and a less invasive intervention compared to grafting procedures.

Nobel Biocare Zygoma implants are the most documented zygomatic implant solution on the market for the severely resorbed maxilla. Not only does the procedure avoid complex bone-grafting, Zygoma implants show remarkable survival rates in a long-term study, with an average implant CSR of 95.12% after 10 years.3

Surgical flexibility

Building on 25 years of success with Nobel Biocare’s zygomatic implants, the new NobelZygoma implants anchor in zygomatic bone and provide an excellent option for treating severe maxillary resorption without bone grafts. They have an unthreaded implant body designed to interface with soft tissue, and depending on the anatomical situation parts of the implant body can be located outside of the maxillary sinus. For the extra maxillary placement the coronal part of the implant should still have bone support. This technique enables a position of the implant head close to the crest of the alveolar ridge that facilitates a prosthetic procedure which in turn offers easier cleaning and better comfort for the patient5 while improving phonetics.6

The implant of choice for severely resorbed maxilla

The zygomatic implant has become the implant of choice for cases with a severely resorbed maxilla. Without this implant, many patients would otherwise require invasive grafting procedures to establish adequate bone volume for the placement of conventional implants. Zygomatic implants help avoid grafting and shorten treatment time, with significant improvements in function and esthetics.4 The zygomatic concept addresses the needs of this patient group by providing the implant surgeon more treatment options for the edentulous maxilla.
