 Why Airotor Handpieces Wobble: Common Causes and Fixes

A smooth-running airotor handpiece is essential for precision and patient comfort. If you notice a wobble or vibration during use, it’s a sign something isn’t right. Here are the most common reasons for this issue:

1. Worn-Out Bearings

Bearings inside the turbine wear out over time, causing instability. This is the most common cause of wobbling and often requires turbine replacement.

2. Bent or Damaged Bur

Using a bent or low-quality bur can create imbalance and lead to wobbling. Always use high-quality burs and inspect them before use.

3. Loose or Improperly Inserted Bur

If the bur isn’t seated properly in the chuck, it may vibrate during operation. Ensure it clicks firmly into place before use.

4. Turbine Cartridge Misalignment

A misaligned or poorly installed turbine can cause eccentric rotation, leading to a noticeable wobble.

5. Poor Maintenance

Lack of regular cleaning and lubrication can cause internal components to degrade, leading to vibrations and instability.

Quick Fix: Replace the turbine or bur, and always follow proper maintenance protocols. A simple servicing can often restore smooth performance.

A wobbling handpiece isn’t just uncomfortable—it affects your clinical precision. Timely inspection and care can keep your airotor running at peak performance.
