The zygomaticus implant (Brånemark system, Nobel Biocare, Gotebörg, Sweden) was developed for patients with severe bone resorption of the posterior maxilla, which may eliminate or minimize the need for bone grafting. Although the zygomaticus implant has had a remarkable success rate in a difficult patient population, the method requires an advanced surgical technique and carries increased risk of complications, such as the perforation of the orbital floor or infratemporal fossa. Although it is important to have a detailed understanding of the anatomy of the zygomatic bone when performing the installation, there have been few anatomic studies on the zygomatic bone for installation of zygomaticus implants. In this study, we measured the height and thickness of the zygomatic bone for the installation. The thickness at a 90-degree angle point, where the upper margin of the zygomatic arch and the temporal margin of the frontal process of the zygomatic bone intersect and where the apex of the implant penetrates, according to the original method, was 1.8 ± 0.4 mm, which gradually increased inferiorly and anteriorly. In conclusion, the penetration point of the apex of the zygomaticus implant should be located more inferoanterior to the 90-degree angle point, as the thickness of the 90-degree angle point is thinner than the diameter of the implant. Based on these results, we have proposed a newer and safer installation method for the zygomaticus implant using a drill guide, which can be easily made.
