颧肌种植体是为上颌后牙严重骨吸收患者而研制的。这些可能会消除或最大限度地减少植骨的需要。尽管颧肌植入物在这一难以治疗的患者群体中显示出显著的成功率，但该方法需要先进的手术技术，并增加了并发症的风险。关于颧骨与颧骨种植体植入的关系的解剖学研究很少。本研究测量了颧骨附着体的高度和厚度。在颧弓上缘与颧骨额突的颞缘相交与种植体尖穿透的90角点处的厚度为1.8+/-0.4 mm，向下向前逐渐增加。因此，颧骨部种植体顶端的穿透点应位于90度角点的下方，因为该区域的厚度比种植体的直径薄。基于本研究的结果，提出了一种更新、更安全的使用钻头导向的颧骨种植体植入方法。
The zygomaticus implant was developed for patients with severe bone resorption of the posterior maxilla. These may eliminate or minimize the need for bone grafting. Although the zygomaticus implant has shown a remarkable success rate in this difficult-to-treat patient population, the method requires an advanced surgical technique and carries an increased risk of complications. There have been few anatomical studies on the zygomatic bone in relation to the insertion of zygomaticus implants. The height and thickness of the zygomatic bone for the insertion were measured in this study. The thickness at the 90 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, was found to be 1.8 +/- 0.4 mm; this gradually increased inferiorly and anteriorly. Thus, the penetration point of the apex of the zygomaticus implant should be located more inferoanterior to the 90 degrees angle point, as the thickness in this region is thinner than the diameter of the implant. Based on the results of this study, a newer and safer insertion method for the zygomaticus implant using a drill guide is proposed.
