The Arcsys System has been designed to provide a pure frictional fitting that is compact and does not require a screw, which, many times, is the cause for the loosening or fracture of prosthetic components, due to the fatigue process from masticatory loads. The frictional concept offers more safety for the patient because the continuous forces of mastication, which maintain the implant/abutment connection secure, assure the retention of the prosthetic component into the implant. When compared to other connections it shows superior results.
