Nobel Biocare Global Symposium 11 products NobelZygoma Zygomatic implants for graftless treatment of severe maxillary resorption by Nobel Biocare For patients with severe maxillary resorp- tion, extensive grafting procedures can mean lengthy treatment times—but there is an alter- native: By anchoring in the zygomatic bone, the NobelZygoma implant system can enable an immediate loading protocol for graftless treatment. This dramatically shortens time to teeth for increased patient satisfaction and allows patients with severely resorbed max- illae to return to a normal quality of life.1 Moreover, it offers a broad choice of pros- thetic options. 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 aver- age 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 with grafting procedures. NobelZygoma implants are the most doc- umented zygomatic implant solution on the market for the severely resorbed maxilla. Not only does the procedure avoid complex bone grafting, but NobelZygoma implants have also shown remarkable survival rates in a long-term study, with an average implant cumulative survival rate of 95.12 percent af- ter ten years.3 Surgical flexibility Building on 25 years of success with Nobel Biocare’s zygomatic implants, the new NobelZygoma implants anchor in zygo- matic bone and provide an excellent option for treating severe maxillary resorption without bone grafts. They have an un- threaded implant body designed to inter- face with soft tissue, and depending on the anatomical situation, parts of the implant body can be located outside of the maxillary sinus. For extramaxillary placement, the coro- nal 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 clean- ing and better comfort for the patient4 while improving phonetics.5 The implant of choice for severely resorbed maxillae The zygomatic implant has become the implant of choice for cases of severely re- sorbed maxillae. Without this implant, many patients would otherwise require invasive grafting procedures to establish adequate bone volume for the placement of conven- tional implants. Zygomatic implants help avoid grafting and shorten treatment time, with significant improvements in function and esthetics.6 The zygomatic concept addresses the needs of this patient group by providing the implant surgeon with more treatment op- tions for the edentulous maxilla.
