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.

Fixed Prosthesis Installation: An Aviation Analogy

Abstract: What is an optimized fit and what does that have to do with Position, Yaw, Pitch and Roll? 

In dentistry, connection stability is important from a mechanical and biological point of view. Optimized fit terminology can be used to describe a connection that can remain stable under load over time. The longer the better. Optimally fitting parts can also be expected to prevent the passage and proliferation of oral microbes in and about them. This could prevent related oral diseases.
