Crestal Lift Control Basic
This system for Crestal Sinus Lift facilitates a simple, safe augmentation of the sinus floor. Elevation occurs during the transcrestal drilling process. The stop sleeve system is coordinated with special instruments to prevent the membrane from being injured or punctured. In addition to the special atraumatic design of the Crestal drill with its four cutting edges and the concave head for safety forming a conical bone flat, this Crestal drill is also ideal for collecting bone chips.
