The Reverse Margin™ is a design feature that describes the shape of the margin built into a custom abutment and its complimentary prosthesis. It affects the direction of flow of cement during the process of intra-oral cementation. The Reverse Margin™ redirects the flow of the cement away from, rather than into the tissues that surround dental implants. This margin design can be used as part of the Cement Control System™ proposed by Emil L.A. Svoboda PhD, DDS, to prevent or reduce the occurrence of peri-implant disease.

Abstract:As knowledge about dental implant treatment increases, there is a compelling need to add new words and phrases to the dental glossary to  support easier and more precise communication, and to open new frontiers for dental research. The intent of this publication is to define new terminology that exposes the root causes of prosthesis installation related treatment complications, and to show how their negative effects can be mitigated.
