ACS – Angulation Corrective System – Exocad

Philip Segal MDT


Internal Hex Connection

ACS abutments are for precision manufactured  CAD/CAM screw retained restorations where angulation  of the screw access hole is required for improved  aesthetics and/or function. The ACS system permits  angulation of the screw access hole up to 20 degrees.

This is achieved with the aid of a special designed  abutment screw & screwdriver (hand or ratchet) to  facilitate precise tightening of the abutment screw at the  required torque.

Conical Connection

The ACS system offers the dental technician control over  the desired position of the screw access hole, this is  beneficial in the anterior segment to ensure the screw  access hole is in the cingulum area without  compromising the buccal aspect of the soft tissue with  the use of an angulated abutment.

Angulation of the screw access  hole to the palate or lingual  aspect in the posterior zone will  facilitate an uncompromised  occlusal surface for improved  aesthetics & function.
