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.

Questions
Ask a questionits nice would you please tell me after construction of crown
its nice would you please tell me after construction of crown what parameter of occlusion must be included
Because the loss of the teeth was due to an accident, was the placement of the implants performed immediately?

How do you manage ?
Traumatical loss of anterior teeth might end up in fracture of cortical bone...that leads to decreased bone quality ..in this case is there any evidence of such findings?? And how do you managed the soft tissue ??

Access hole closure?
Very nice work! Was the access hole closed with composite or the full porcelain crown was cemented over implant zirconia abutment? A finish line is present lingually but a lingual undercut was present too. If you can clarify, thank you!
