Anterior restoration using angulated screw channel abutments
Dr. Benjamin Cortasse
France
“This new solution gives both the restorative dentist and the dental technician more options. Greater flexibility helps ensure the best possible treatment outcome. Thanks to the free placement of the screw axis, the esthetic properties (such as translucency) of the ceramics can be optimized, while preserving the advantages of the screw-retained solution."
