NSK iSD900 Cordless Implant Prosthetic Screwdriver with Torque Calibration System (TCS)

• Torque Calibration System (TCS) enables fast calibration within seconds, ensuring precise torque accuracy and reliable screw fixation.

• Wide torque range (10–40 Ncm) adjustable in 1 or 5 Ncm increments allows accurate torque selection for various implant systems and prosthetic procedures.

• Three rotational speeds (15, 20, 25 min⁻¹) accommodate different clinical requirements with controlled performance.

• LCD digital display panel clearly shows torque, speed, reverse rotation, battery level, and calibration mode for intuitive operation.

• Single-handed operation with enhanced visibility eliminates two-handed ratchet use, improving field access and procedural efficiency.

• Removable sterilizable on/Off switch lever ensures comfortable activation while supporting cross-infection control standards.

• Universal compatibility makes it suitable for major implant systems across diverse restorative workflows.

Q1. How does the Torque Calibration System (TCS) improve clinical safety?
The TCS allows rapid chairside calibration, ensuring accurate torque delivery and reducing the risk of over- or under-tightening prosthetic screws.

Q2. Is the iSD900 suitable for implant fixture placement?
No, the iSD900 is designed for prosthetic screw fixation, including cover screws, healing abutments, and prosthetic components—not for surgical implant placement.

Q3. How does the adjustable torque range support different implant systems?
With a torque range of 10–40 Ncm in 1 or 5 Ncm increments, clinicians can precisely match manufacturer-recommended torque values across various implant brands.

Q4. What are the advantages over a manual ratchet wrench?
The cordless, single-handed operation improves visibility, reduces operator fatigue, enhances efficiency, and delivers more consistent torque control.

Q5. How does the device support infection control protocols?
The removable on/Off switch lever is fully sterilizable, supporting standard cross-infection control requirements in implant practices.
