S4 Piezomed Sinus Lift Tip
The W&H Piezomed instrument range includes different instruments for bone surgery, periodontology and extraction, for retrograde endodontics and for lateral sinus lift.
As soon as an instrument is inserted, Piezomed automatically detects the instrument and assigns it to the correct power class. This not only facilitates operation but also increases safety. In addition, the risk of overloading the instruments is reduced and the service life of your instruments considerably extended!
Instruments for Lateral Sinus Lift
S4 (REF 05542300)
Instrument with rounded edges for atraumatic detachment of the Schneiderian membrane.


Why Choose The W&H S4 Piezomed Sinus Lift Tip?
Rounded Atraumatic Design- The S4 features a smooth, rounded working end that gently glides along the bony sinus floor, making it ideal for final membrane detachment. Minimises the risk of membrane perforation---critical for predictable grafting and impant outcomes.
Gentle Ultrasonic Vibration- Like all Piezomed tips, the S4 uses ultrasonic technology to vibrate with high precision. Offers greater tactile control than rotary instruments, especially near the delicate sinus membrane.
Part of a Structed Protocol- Typicaly used after initial detachment with S3, the S4 tip continues the elevation process smoothly. Integrates into W&H's stepwise approach to lateral sinus lift surgery: S1- outline the bony window, S2- enlarge the window, S3- start membrane separation, S4- continue detachment with greater reach and control, and S5- complete elevation if needed.
Automatic Tip Recognition for Optimal Power- When inserted into the W&H Piezomed unit, the S4 tip is automatically detected, and the power level is adjusted accordingly---ensuring optimal performance and safety every time.
W&H Quality and Reliability- Crafted by W&H, a global leader in piezo surgery, the S4 is built for durability, precision, and consistent clinical outcomes.
This tip is ideal for the final stages of sinus membrane elevation, for surgeons who are seeking a gentle, low-risk technique for accessing the sinus cavity, and integration into advanced, minimally invasive implant protocols.
