C-TW3
Electric Torque Wrench
The C-TW3 is a compact, cordless electric torque wrench for implant dentistry — delivering precise, controlled torque from 10 to 55 N·cm at low speed. Rechargeable and free of a trailing cord, it pairs a simple multi-button layout for one-touch control of torque, speed and direction with an intelligent deceleration mode that eases off automatically as the target torque approaches — for confident final seating at just 100 g in the hand.
What clinicians are saying
Real-world feedback from implant clinicians using the C-TW3 for seating and torque verification.
"For final seating I want to feel in control of the last few N·cm, not just hear a click. The deceleration mode slows the driver right down as it nears the set value, so I'm placing the abutment smoothly instead of over-running the torque. Reading the exact figure off the device takes the guesswork out of it for me."
"It's light enough that my hand doesn't tire on a longer list, and small enough to get a straight line into the posterior. Switching torque, speed and direction from the buttons keeps my attention on the patient rather than on setting up the instrument. For routine placements it's become the one I reach for."
Precise torque, in a tool that disappears in the hand
Three things an implant clinician wants from a powered torque driver — an accurate number, a controlled finish, and a body light enough to forget about.
A 10–55 N·cm range in 5 N·cm steps, held to ±3 N·cm — set the value for the system in front of you and let the device control the finish.
Intelligent deceleration eases the driver down as it nears the target, so final seating is smooth and controlled rather than an abrupt stop.
About 100 g and roughly 17 mm across — a slim, balanced body that reduces hand fatigue and reaches straight into the posterior.
Designed around the final few newton-centimetres
Every detail of the C-TW3 is built to make controlled, repeatable torque delivery simple at the chairside.
Precision
Set the number, hold the number
Torque is set across 10–55 N·cm in 5 N·cm increments and held to ±3 N·cm, so the value you choose for the implant system is the value delivered — read directly from the device rather than estimated by feel.
Control
One-touch torque, speed & direction
A simple multi-button layout gives direct access to the four core functions — torque, speed, direction and calibration — with forward/reverse at your fingertips, keeping attention on the patient, not on the instrument.
Access
Rotatable head for every position
The handpiece head rotates to improve the line of approach to different intraoral positions — helping deliver straight, controlled torque even in the posterior, where access is tightest.
Cordless & Ergonomic
Light in the hand, free of a cord
A cordless, rechargeable handpiece at about 100 g and a maximum grip diameter near 17 mm — the balanced body moves freely at the chairside without a trailing cord, reducing operator fatigue across a full implant list. Recharged between cases via the AC adapter.
Two ways to reach the target
Choose a constant-speed finish or an automatic deceleration as the target torque approaches.
Constant speed control — the driver runs at the set speed and stops immediately once the target torque is reached.
Above a set speed of 20 r/min, the driver slows automatically — reducing by 10 r/min (with a beep) as torque reaches 60% of the set value, and again at 90% — then returns to speed as the load eases, for a smooth, controlled final seating.
After activation, the C-TW3 runs a 15-second automatic calibration countdown before use.
Low speed, high torque — where it's needed
A powered torque driver for the controlled, low-speed stages of implant and related procedures.
Controlled, low-speed insertion of the implant fixture to the target torque.
Seating and final torque of abutments to manufacturer-specified values.
Precise placement of orthodontic mini-screws at controlled torque.
