Abstract
An immediate dental implant shell has outer, multiple zones for engaging a soft tissue socket left immediately after tooth extraction from a bone socket. The zones have combinations of different biologic agents, macro- or micro-geometric, or micro- or macro-morphology irregularities to better engage gingival sulcus, junctional epithelium and dento-gingival fiber zones of the soft tissue socket. The shell may also have various guide markings and projections to aide drilling of the implant hole in the bone socket. A dental implant is placed in the drilled implant hole before or after the shell has been placed in the soft tissue socket, and has an axis that is independent of the shell axis so the shell and implant both sit in optimum positions in their respective soft and bone sockets.
