The Stern AC Implant is a self-tapping, double thread screw im¬plant, manufactured from pure grade 4 titanium. The implant is acid etched except for the neck, which is machined to a smooth finish. Stern AC Implants are manufactured with a flared neck, used for one-stage, transgingival implantation. The neck and body include an internal taper and octagon. The implants are manufactured with three body diameters, 3.3 mm, 4.0 mm, and 5.0 mm, all with the same prosthetic head. Intended to be used in dental implant applications for oral rehabilitation of edentulous and partially dentate patients in the maxilla and mandible. Implant retained restorations may consist of single crowns or bridges as well as complete or partial dentures. The Stern AC Dental Implant System is intended for delayed loading. It is also indicated for immediate loading with good primary stability and appropriate occlusal loading.
A prefabricated device intended to provide a permanent intermediate fixture level between a dental implant and the final prosthesis/restoration (e.g., bridge, single tooth, overdenture). It includes one or more structural component(s) [e.g., abutment, ball, bar, bar overlay, coping, ring], and may be made of various materials [e.g., titanium (Ti), plastic, gold alloy]. It includes devices glued to prostheses and/or devices that can be replaced during cleaning cycles. An abutment screw(s) may be included, however the suprastructure does not represent the screw(s) in isolation. It may also be referred to as an abutment assembly or mesostructure.
