Meet The Reverse Margin™ Design

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 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 peri-implant disease.

WHY USE REVERSE MARGIN™

Reduce Number of Infections

The Reverse Margin™ design helps control excess cement during the process of intra-oral cementation. Safer intraoral cementation is expected to reduce peri-implant disease related to residual subgingival cement and misfit implant-abutment connections. These complications are often related to current prosthesis installation procedures.

Increase Patient Satisfaction

Choosing the Reverse Margin™ design helps the dentist get better results that reduce or eliminate some of the risk factors that are known to cause failure of implant treatment. Your patients will be happier if their treatment lasts longer!

Increase Success Rate

Residual excess cement and misfit implant-abutment connections are two major risk factors known to contribute to the failure of dental implants and their attached teeth. The reduction or elimination of these contributing factors are likely to decrease failure rates. Choose the Reverse Margin™ design to make treatment better for your patients

Decrease Liability

It does not bode well for the dentist, when residual cement is detected in the peri-implant complex of a failing dental implant, or when the prosthesis installation process used, is known to cause implant-abutment misfits. Treatment failure can be expensive; maintenance of ailing-failing implants, removal of failed implants and attached prosthetics, paperwork and legal fees. Choose to use new installation protocols that reduce risk factors that are known to cause complications.

Cement Control System

It is a term used to describe a combination elements that can be used to help reduce the incidence peri-implant disease and early failure of dental implants. Study the Short Award Winning Slide Presentation to understand more.

For those who like to use “Retrievable Prosthetics” and also wish to reduce their treatment complications, consider using the “Simplified Svoboda Modification” as your favorite implant prosthesis installation technique. Read more about it here.
