New Material for CAD/CAM-based Restorative Dentistry
Thursday, September 21, 2017
In response to the limitations of high-strength ceramics, new polymer-based resin composite materials have been developed.
This new category of CAD/CAM composites provides clinicians with the capability of restoring teeth in one appointment.
Restorations fabricated from these materials achieve better marginal integrity and less avulsion.
Why is feldspathic porcelain no longer the restorative material of choice for many clinicians? Although esthetic, porcelain is brittle with a low fracture toughness and a high proneness to failure in the presence of flaws.
To overcome this problem, new materials with greater strength were pursued. As a result, now you can take your restorative practice to the next level with a new generation of CAD/CAM composites offering high flexural strength, better marginal integrity, fast milling, and tooth-resembling esthetics. This new category of materials (referred to as CAD/CAM composites and/or hybrid ceramics) represents the synergy of ceramics and composites with their respective beneficial mechanical properties.
This article explores the many advantages of this new generation of CAD/CAM composites, along with offering a case presentation.
