New CrCo (Cobalt-Chrome) interfacecombined with a castable-sleeve opens upfurther restorative options for DESS productusers.Thanks to the included burnout, the workcan be performed directly on CrCo, castingon a small scale to produce crowns ready tofire porcelain on while retaining the DESSquality of the implant connection.By having engaging and non-engagingversions, both single and multiple unitstructures can be made. All can be welded tothe CrCo base if they are made also in CrCo.Interfaces in this material have shown avery valid economic alternative to the moreexpensive precious metal alloys.
