The procedure for placing zygomatic implants using the ZAGA approach minimizes the need for a maxillary osteotomy by not having to open a “window” in the maxillary bone, as other techniques propose. This maximizes the area of contact the implant has with the zygomatic bone without having to make an unnecessary opening in the bone. Such a procedure not only involves greater precision in making such a perforation, but also allows for a solid seal of the sinus osteotomy and for enhanced implant stability.
With the ZAGA approach, the patient receives individualized treatment. The implant is placed through a minimally-invasive osteotomy, always preserving the palate. The zygomatic implant can be both inserted from the outside through the alveolar bone, which protects the sinus, as well as through a more intra-alveolar approach, depending on the patient’s maxillary anatomy. With this approach, more bone is conserved in the critical area near the alveolar ridge, the integrity of the Schneider membrane is maintained and the soft tissue around the implant head is healthier. The better the sealing is, the less chance there is of bacteria getting through.
In subsequent publications, the ZAGA method shows it has long-term, proven benefits over the original technique. The ZAGA approach offers a methodology that can systematize zygomatic implant placement and has proven to show successful results without long-term complications and with the added benefit of having more aesthetic and functional fixed teeth within 24 hours following the procedure.
