- A specialized 10:1 reduction endodontic contra-angle handpiece designed for reciprocating motion, specifically engineered to automate the use of manual hand files
Uses
- Mechanical Hand Filing:
- Automates the traditional manual cleaning and shaping of root canals, providing a bridge between manual and rotary techniques
- Initial Canal Exploration:
- Ideal for the initial stages of endodontic therapy where hand files are typically used to establish a glide path
Features
- 10:1 Gear Reduction:
- This ratio converts a standard motor's speed into high-torque, low-speed rotation (typically 200–900 RPM depending on the motor) for controlled root canal preparation
- 90° Reciprocating Motion:
- The head moves in a 90-degree back-and-forth "watch-winding" arc rather than full continuous rotation
- Manual File Compatibility:
- It is uniquely designed to accept standard hand files (K-files, H-files, etc.) rather than just rotary-specific files
- Push-Button Release:
- Features a convenient push-button mechanism for fast file insertion and removal
- Universal E-Type Connection:
- Compatible with any standard E-type motor, including air-driven and electric systems
Benefits
- Reduced Hand Fatigue:
- By automating the reciprocating motion, it significantly reduces the physical strain on the clinician's hand and wrist during long procedures
- Clinical Safety:
- The reciprocating movement and 10:1 reduction helps prevent file binding and breakage, which is a higher risk with continuous rotation
- Superior Efficiency:
- Completes canal instrumentation faster than manual manipulation while maintaining the tactile feel often lost with high-speed rotary systems
- High Value:
- Offers a professional-grade alternative to expensive "house brands" (like Schein or Patterson), maintaining performance at a more accessible price point
