    • One embodiment of the invention includes a sinus tarsi implant with an inverted thread profile having a lip or lips at the thread crest. The lips may help hold tissue in-growth and give greater purchase to the implant. The implant may also include voids that traverse threads. The voids may create an open area for soft tissue to grow into. The voids may be relatively small and consequently promote faster tissue in-growth. Thus, the lips and/or voids limit migration. They do this without creating sharp edges or pressure points (or at least limiting such creation) that are typically associated with techniques (e.g., cutting deep negative thread spaces) used to prevent migration. Therefore, the embodiments of the invention limit migration while also limiting patient discomfort. Other embodiments are disclosed.
    • 本发明的一个实施例包括具有在螺纹牙顶处具有唇缘或唇缘的倒置螺纹轮廓的窦性牙龈植入物。 嘴唇可能有助于保持组织生长,并更多地购买植入物。 植入物还可以包括穿过螺纹的空隙。 空隙可能产生软组织生长的开放区域。 空隙可能相对较小,从而促进组织生长更快。 因此,嘴唇和/或空隙限制了迁移。 它们不会产生通常与用于防止迁移的技术(例如,切割深负螺纹空间)相关联的尖锐边缘或压力点(或至少限制此类创建)。 因此,本发明的实施例限制了迁移,同时也限制了患者的不适。 公开了其他实施例。
