The Sinus Set designed by Dr. A. Kirsch and Dr. K.-L. Ackermann has a wide variety of uses in dental surgery and implantology, for example in the course of sinus floor elevation in the preparation of Schneider’s membrane, in full flap and split flap development, or in augmentation procedures. The Sinus Set contains nine instruments with working ends on both sides, a tray, and a medical beaker. The working ends are different in angle size and shaped as rasps, elevators, cones, or pears.
