阅读说明：本技术 具有局部微螺纹/凹槽的非对称颧骨牙种植体 (Asymmetric zygomatic dental implant with local micro-thread/groove ) 是由 卡洛斯·阿帕里西奥 格雷厄姆·艾伦·布莱克比尔德 理查德·格雷厄姆·保克 于 2019-02-19 设计创作，主要内容包括：颧骨牙种植体包括大体上圆柱形的主体、内部螺纹孔和非对称外部特征。大体上圆柱形的主体具有冠状部分和顶端部分。大体上圆柱形的主体具有主中心轴线。内部螺纹孔形成在大体上圆柱形的主体的冠状部分中,用于容纳被配置成可移除地保持与所述颧骨牙种植体接合的基台的螺钉。内部螺纹孔具有孔中心轴线。非对称外部特征位于大体上圆柱形的主体的第一侧的至少一部分上,使得非对称外部特征被配置成直接接合患者的牙槽骨。非对称外部特征包括多个周向延伸的凹槽。(The zygomatic dental implant includes a generally cylindrical body, an internal threaded bore, and an asymmetric external feature. The generally cylindrical body has a coronal portion and an apical portion. The generally cylindrical body has a major central axis. An internal threaded bore is formed in the coronal portion of the generally cylindrical body for receiving a screw configured to removably retain an abutment engaged with the zygomatic dental implant. The internally threaded bore has a bore central axis. The asymmetric external feature is located on at least a portion of the first side of the generally cylindrical body such that the asymmetric external feature is configured to directly engage an alveolar bone of a patient. The asymmetric outer feature includes a plurality of circumferentially extending grooves.)
