The Angulated Screw Channel (ASC) System for Replacement of Two Maxillary Central Incisors
This case concerns a 35-year-old male patient who lost teeth #11 and #21 FDI (#8 and #9 US) in a car accident. The treatment selected for replacement of both central incisors was based on the angulated screw channel (ASC) system and involved placement of two screw-retained single units and two Nobel Active Implants. The two ASC crowns were designed virtually, using the 2G NobelProcera scanner.
The ASC system was used because it allows for an angulation of 25° between the implant long axis and the crown. It also permits the use of screw-retained implant crowns instead of individual abutments and cemented crowns to correct the angle of the screw access hole.
