Inverted body-shift concept in macroimplant design to enhance biologic and esthetic outcomes: A clinical report
Abstract
A new implant design to increase labial plate dimension and tooth-implant distance in maxillary anterior extraction sockets over traditional tapered implant designs is presented. Generally, tapered implants are divergent and wider at the coronal aspect of the implant adjacent to the lowest bone volume. Decreasing bone around implants over time can lead to ridge collapse, recession, and a graying effect of the gingival tissues that eventually impacts esthetic outcomes adversely. This implant design incorporates a body-shift in both diameter, shape, and thread pattern and reduces the coronal portion to allow greater circumferential bone thickness to be created where it is needed most for long-term stability.
