Soft tissue preservation temporary (SHELL) immediate-implant abutment with biological active surface

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.

AI Technical Summary

Benefits of technology

The invention is a soft-tissue preservation and dental implant arrangement method and apparatus. The hollow shell of the invention has a unique structure that makes direct contact with the soft-tissue socket, promoting soft-tissue attachment and adherence. The shell is designed with a textured and coated outer surface that parallels the upper edge of the shell and includes three distinct zones corresponding to the sulcular epithelium, junctional epithelium, and dento-gingival fibers. The invention provides a solution for preserving soft-tissue during tooth removal and promoting bone regeneration for dental implant placement.

Problems solved by technology

As the soft tissue collapses into the socket bone drilling preparation is greatly compromised as visualization and obstruction by the soft tissues becomes a complicating factor during the immediate implant placement at the time of tooth extraction.
