Abstract:
1. A dental implant system comprising: a lower implant body configured to be implanted in bone and defining a centerline; an upper implant body coupled to the lower implant body, thereby forming a cavity between the upper and lower implant bodies, the upper implant body comprising an opening to the cavity, the opening having a perimeter; and a rotatable, swivelable anchor comprising: an anti-rotation cavity formed in the base; and an anti-rotation post fixedly coupled to the lower implant body, the anti-rotation post projecting into the cavity between the upper and lower implant bodies and into the anti-rotation cavity, wherein the anti-rotation post and anti-rotation cavity are configured to cooperate so as to resist rotation of the anchor relative to the lower implant body about the centerline while allowing rotation of the anchor relative to the lower implant body about axes perpendicular to the centerline.
