How does the angulated screw channel and "55 degrees of restorative freedom" help me clinically?
Implants are not always placed in an ideal restoratively driven trajectory, and a screw access hole that exits through a facial surface is both an esthetic and a structural problem. NobelProcera's angulated screw channel (ASC) technology is designed to solve exactly that, and it can be used at the multi-unit abutment level as well as at implant level so the access channel can be redirected to a more ideal, less visible position.
The headline figure of 55 degrees of restorative freedom is the sum of two corrections, available 360 degrees in any direction:
| Source of correction | Range | Clinical contribution |
|---|---|---|
| Multi-unit abutment angle | Up to 30° | Sets the foundational correction at the abutment level. |
| Angulated screw channel | Up to 25° | Adds further redirection on top of the abutment, in any direction. |
| Combined total | Up to 55° | Repositions the screw access to a stronger, less visible location. |
An important clarification: the 55 degree figure is not an invitation to place implants at 55 degrees, which can be contraindicated in many clinical situations. It exists so the clinician can place implants where they are secure in the available bone and anatomy, and then bring the screw access back to a position that gives the restoration better overall strength and esthetics, without compromising structural integrity or requiring extensive surgical correction.
As a structural bonus, NobelProcera uses screw access holes that are 25% smaller than conventional channels, which preserves occlusal and facial esthetics while supporting strength through optimized material distribution. ROE's "NobelProcera ASC" video on the product page walks through this feature.
