 If a Handpiece Falls: Is Changing the Cartridge Enough? What If There's a Dent?

When a dental handpiece (like an airotor) falls, many dentists think "Let me just change the cartridge—it’ll be fine."
That’s partially correct, but not always enough. Let’s understand why.

 

🔹 Step 1: Cartridge Replacement After a Fall

Yes, replacing the cartridge (which includes the bearings, impeller, spindle, and chuck) can often restore performance if the damage is limited to the internal rotating parts.
This helps fix issues like:

• Noisy operation
• Poor bur grip
• Reduced speed
• Vibration due to bearing damage

✅ So, if the outer shell is intact, changing the cartridge often works well.

 

🔹 Step 2: What If There's a Dent on the Head (Outer Shell)?

If there’s a dent on the handpiece head (near the bur area), even after replacing the cartridge, you may still face problems:

Here’s why:

• Imbalance: The dent can throw off the rotor's balance, causing continued vibration or noise.
  
  
• Bur misalignment: The bur may not rotate centrally, affecting cutting precision.
  
  
• Turbine clearance issues: A dented head can reduce internal space, causing friction or rubbing against the cartridge.
  
  
• Overheating risk: Improper airflow and friction can generate heat, making procedures unsafe or uncomfortable.

 

🔹 ⚠️ Summary: If There’s a Dent, Changing the Cartridge May Not Be Enough

Even a small dent in the head cap or shell can make a difference. You might fix the internal mechanism—but the geometry and airflow of the handpiece are still compromised.

 

🔧 What’s the Best Practice?

1. Minor drop, no dent? → Change cartridge and test.
   
   
2. Visible dent on head or body? → Best to replace the head cap (if detachable) or the entire shell.
   
   
3. Unsure? → Send for service evaluation. Reputable brands or dealers (like BRIXO-authorized centers) can check with precision tools.

🦷 BRIXO Tip

BRIXO handpieces are designed with sturdy external bodies and high-quality cartridges—but like all high-precision instruments, a physical dent after a fall can still affect long-term performance.

Always handle your airotor with care—and when in doubt, get it professionally inspected.

Why Are Airotors Damaging So Fast? Let’s Talk Metal Crowns & the Right Way Forward

Why Are Airotors Damaging So Fast? Let’s Talk Metal Crowns & the Right Way Forward

A common frustration among dentists today is the frequent damage or wear-out of airotors, even when they’re relatively new or from reputed brands. The problem becomes especially noticeable when used for cutting metal crowns or bridges. So what’s going wrong? Let’s dig deeper.

The Real Issue: Misuse, Not Manufacturing

Most high-speed airotors are precision instruments designed primarily for enamel, dentin, and restorative materials — not hard metals like PFM or zirconia crowns. Using them to cut through metal can result in:

Overheating of bearings, Imbalance in turbine rotation, Chipping of internal rotor blades, Rapid wear-out of head and chuck systems

Metal Cutting Needs Specialized Tools

Attempting to cut metal crowns with airotors is like using a surgical scalpel to cut through sheet metal — not what it’s built for.

Instead, dentists should:

 Use slow-speed handpieces with carbide burs or metal-cutting discs,  Reserve airotors and diamond burs strictly for enamel, composite, and ceramics,  Educate clinic assistants on proper cleaning & sterilisation to prolong lifespan

Protect Your Investment

Airotors are not just tools — they’re investments in precision, time, and patient comfort. When used properly:

They deliver smooth, vibration-free cutting, Ensure longevity of both the instrument and burs, Offer safer and quieter patient experiences

BRIXO's Recommendation

At BRIXO, we believe in responsible usage and education. Our BRIXO Dental Diamond Burs are made for clinical excellence, but even the best burs or handpieces cannot withstand misuse. Our engineers advise:

Use BRIXO airotors for enamel, dentin, composite,  Never cut metal with high-speed handpieces,  Train junior dentists and assistants on bur selection and airotor protection.

 Final Thought - Don’t blame the tool when it’s a usage mismatch. Choose the right instrument for the right task and you’ll experience why more than 1000 dentists trust BRIXO to deliver precision and performance — day in, day out.
