Endodontic treatments are becoming less invasive. Creating smaller openings and keeping the truss intact for better healing and tooth strength is growing in popularity. We've had small form factor tips since the company started with our SP2, UT4 and SJ4 but they have been very specialized instruments.
We took our SJ4 and opened the bend angle, decreased the working length, and added extended diamond plating. The result is a small form factor tip with increased durability and better cutting power than our SP2 and SJ4 ultrasonic tips.
