7 Common Reasons Dental Airotor Handpieces Fail — And How to Prevent Them | BRIXO Guide
Dental airotor handpieces are the backbone of efficient
clinical procedures. Their high-speed precision makes them indispensable in any
modern dental practice. However, frequent use combined with improper care can
lead to premature failure. At BRIXO, we believe that understanding why
these failures happen is the first step to extending your handpiece’s lifespan.
Here are the 7 most common causes of dental airotor failure—along
with simple, effective ways to avoid them:
One of the leading causes of failure is insufficient or
incorrect lubrication. Without proper oiling, internal components like bearings
experience excess friction, accelerating wear and tear. To prevent this, apply
the recommended lubricant regularly—especially after every cleaning or
sterilization cycle.
BRIXO Tip: Always use high-quality,
handpiece-specific lubricant, and follow a consistent maintenance routine.
2. Accidental Dropping: Small Falls, Big Damage
Even minor drops can have major effects. A simple slip can
dent the handpiece head, damage the spindle, or distort the bearings and
O-rings—compromising the entire mechanism.
BRIXO Tip: Handle your handpiece like a precision instrument. Use holders or trays during transfers to reduce the risk of accidental falls.
3. Sterilization Errors: Heat Can Harm
While sterilization is essential, incorrect procedures can be
damaging. Overheating or using an uncalibrated autoclave can deform internal
components—especially bearings. This not only affects performance but could
lead to costly repairs or replacements.
BRIXO Tip: Calibrate your autoclave regularly and follow the exact sterilization guidelines for air-driven handpieces.
4. Bur Problems: Bent or Missing Burs Cause Chaos
Using a bent bur—or running the handpiece without one—creates
imbalance, leading to vibrations and bearing strain. Think of it like driving a
car with an unbalanced tire; it wears out faster and runs rough.
BRIXO Tip: Always inspect burs before use. Replace damaged or bent ones immediately, and never operate the handpiece without a bur.
5. Incorrect Handpiece Use: One Size Doesn’t Fit
All
Not all handpieces are built for the same workload. Using a
low-torque or lightweight model for heavy cutting tasks can overwork the motor
and degrade performance. Similarly, using the wrong bur length can destabilize
the mechanism.
BRIXO Tip: Match the handpiece to the task. Use torque-optimized models for heavy-duty work, and avoid excessive bur extension.
6. Poor Cleaning Before Sterilization: Debris
Turns to Glue
If debris like tooth particles, blood, or lubricant residue is
left inside before sterilization, it can harden or become sticky under heat.
This clogs internal components, affecting bearing performance and leading to
early failure.
BRIXO Tip: Clean your handpiece thoroughly after each use—before sterilizing—to protect internal components and ensure long-term reliability.
7. Leaks and Loose Seals: Small Gaps, Big
Consequences
Worn-out backend gaskets or O-rings can cause air and water to
leak, disrupting optimal pressure and rotation. This reduces the handpiece’s
performance and increases stress on internal systems.
BRIXO Tip: Regularly inspect and replace O-rings and gaskets. A good seal ensures consistent performance and efficiency.
Final Word: Prevent Failure, Protect Performance
Maintaining your BRIXO airotor handpiece doesn’t require complex tools or time-consuming routines—just attention to detail and consistent care. By addressing these common causes of failure proactively, you’ll protect your investment, maintain peak performance, and ensure your patients receive the highest standard of care.
