1:5 Fiber Optic Contra Angle Dental Handpiece

1:5 Fiber Optic Contra Angle Dental Handpiece

A 1:5 Fiber Optic Contra Angle Handpiece is a precision low-speed dental instrument primarily used for drilling and preparation during procedures that require high torque and control, such as implantology and endodontics. The "1:5" and "Fiber Optic" are its two most critical defining features.

• Contra Angle: This is a geared attachment that connects to a low-speed micromotor. It changes the angle of rotation from the motor, providing better access to posterior regions of the mouth. The head of the handpiece is angled contra (against) the direction of the shaft.

• Gear Ratio (1:5): This is the most important specification.

• It means the handpiece has a reduction gear system inside.

• For every 5 rotations the micromotor makes, the bur in the contra-angle makes 1 rotation.

• Result: This gear reduction dramatically increases torque (twisting force) while significantly reducing speed.

Imagine the difference between a car's high gear (for speed on a highway) and low gear (for power to climb a steep hill or tow a heavy load). A 1:5 contra angle is the "low gear" of dental handpieces. It trades raw speed for immense power, preventing the bur from stalling when pressing against hard materials.
