Touchpoint Care for the COXO C3-11: Keeping IPR Precise

Orthodontic teams rely on the COXO C3-11 for controlled enamel reduction. Precision depends on every part working well. This guide covers each touchpoint and the habit that protects it.

Touchpoint: The CH-11 Reciprocating Head

The head creates the vertical reciprocating motion. Clean it thoroughly after use so debris does not interfere with the movement.

Touchpoint: The CB-3 Reduction Body

The body carries the gears that provide torque. Follow your manual for lubrication before every sterilization cycle.

Touchpoint: The Chuck

Whether you have a push-button or wrench chuck, keep it clean and check grip weekly.

Touchpoint: The External Spray

Keep the external line clean and straight. Check flow before each session.

Touchpoint: The Connection

Inspect seals weekly and make sure the handpiece fits securely on the motor.

Explore Repair.Dental's monthly maintenance plans, or if wear has already started, request a handpiece shipping label. For questions, see the Repair.Dental FAQ.

The After-Use Routine

Remove the instrument.
Separate the head and body if your workflow allows.
Clean the outside and the spray line.
Lubricate following your manual.
Autoclave, as COXO generally recommends.

Before Each Orthodontic Session

Protect the head from knocks.
Keep head and body together.

Mistakes to Avoid

Skipping head cleaning.
Lubricating after sterilization.

Monthly Precision Review

Once a month, compare the reciprocating motion, torque feel and spray with how they were when the handpiece was new or last serviced. Gradual changes are easy to miss day to day but obvious month to month.
