About the Instrument
This Sinus Elevator is part of the Helmut Zepf ZEPF-Line series, a range of titanium-handled dental instruments manufactured in Germany. The titanium handle offers a favorable strength-to-weight ratio and resists corrosion through repeated sterilization cycles, supporting long-term instrument performance in a busy surgical environment.
The sharp curette design of this Sinus Elevator is suited for lateral window and crestal approaches, providing the tactile feedback experienced surgeons expect when working in close proximity to the sinus membrane. The double-ended configuration reduces instrument exchanges during procedures, contributing to improved workflow efficiency.

This Stiller sinus elevator (sharp, 4.0 mm) is used for releasing the membrane where it adheres to the bone and defining the window margin in a lateral-window sinus lift. Its shank is bendable, so the working angle can be set to the sinus anatomy; the two ends give left and right access. At 4.0 mm it is a wide pattern for broad membrane elevation. The purple ZEPF-Line titanium handle color-codes the pattern; length 19.5 cm.
