A Paradigm Change in Macro Implant Concept: Inverted Body-Shift Design for Extraction Sockets in the Esthetic Zone.

An innovative macro hybrid implant design is aimed at enhancing labial plate dimension and tooth-implant distance while achieving consistent esthetic outcomes. This unique "body-shift" concept in diameter and shape combines a tapered apical portion with a cylindrical coronal portion in a singular implant body design. The overall configuration of the implant is inverted and "convergent" in form toward the implant-abutment interface where bone is thinnest. Conversely, the tapered apical portion is wider where the bone is greatest in volume and vascularity. By reducing the coronal portion of the implant with the inverted body-shift design, a coronal circumferential chamber is created, thereby allowing larger amounts of graft material to be placed labially and interdentally to create a net increased bone dimension. Use of the implant is demonstrated in a case report.
