Benefits of the ASC

Benefits for Anterior Restorations

When restoring anterior restorations, several critical elements are important to control in order to maximize esthetic results:

• Allows for the access hole on the cingulum, this benefits the cosmetics since the access hole must be positioned on the lingual. The ASC delivers the ability to reposition the access hole in most cases.
• Place cement-free screw-retained crowns without compromising esthetics or occlusal function. The ASC facilitates the avoidance of cement-retained restorations. This is critical since it has been recognized that screw-retained restorations are safer than cemented restorations on implant abutments.
• Easy technician handling – the adapter is retained mechanically (without cement), allowing for easy removal and replacement during the veneering process in the lab, and in case any re-firing is required after try-in.
• The low profile of the titanium interface limits the adverse effect on the color of restoration and tissue from titanium interface.
• It is particularly beneficial to be able to screw-retained restorations in the anterior since anterior restorations typically require the ability to manage the soft tissue more than posteriors. Achieving the correct soft tissue contour and ceramic esthetics to mirror the natural adjacent central incisor is the key to success. The ASC increases the ability to place screw-retained restorations that can facilitate tissue shaping.

Benefits for Posterior Restorations

• Retrievability - valued by most clinicians.
• When encountering posterior restorations that have limited vertical opening, the ASC allows angled access to the screw rather than straight access vertical access parallel to the implant root form. (Figures 6 & 7)
