Description
The Dental 1:1 Fiber Optic Low Speed Contra Angle Handpiece is a premium all-metal surgical restorative instrument engineered for high-precision cavity preparation, caries removal, prophylaxis, and finishing. Featuring integrated cellular glass fiber optic illumination, an enclosed internal water spray channel, and an ISO 3964 standard E-type connection, it provides shadow-free visibility and smooth, balanced rotational torque up to 40,000 RPM.
Key Clinical Advantages
- 1:1 Direct Drive Transmission: Delivers true 1:1 rotation speed and stable torque output, ideal for fine restorative sculpting, composite finishing, and prophylaxis polishing.
- Integrated Cellular Fiber Optic Lighting: High-purity optical glass rod channels bright, uniform illumination directly onto the cutting site, preventing dark spots in posterior quadrants.
- Internal Water Spray Cooling: Enclosed inner coolant pipeline delivers a focused water stream directly to the bur-tooth interface, preventing thermal pulp shock without external tubing clutter.
- Reliable Push-Button Chuck: High-precision push-button autochuck mechanism enables rapid, tool-free bur exchanges while firmly securing standard Ø 2.35 mm CA burs.
- Universal ISO 3964 E-Type Fitting: Connects effortlessly to all standard pneumatic air motors and electric micromotors across various dental chair delivery units.
- All-Metal Satin Chrome Casing: High-grade medical stainless steel construction offers excellent tactile control, scratch resistance, and full autoclave tolerance up to 135°C (275°F).

Frequently Asked Questions (FAQ)
Q: What does the 1:1 ratio mean in clinical practice?
A: A 1:1 direct drive ratio transfers the motor's RPM directly to the bur without speed increase or reduction. This provides consistent, controllable tactile feedback ideal for caries removal, cavity prep, and restorative polishing.
Q: Is this handpiece compatible with electric micromotors?
A: Yes. It complies fully with the international ISO 3964 E-type interface standard, making it compatible with both electric micromotors and pneumatic air motors.
Q: What is the sterilization protocol for this handpiece?
A: Clean and lubricate the internal gears after every clinical case, seal it in a sterilization pouch, and autoclave at temperatures up to 135°C (275°F).
