Calibration is a critical maintenance step that ensures the long-term accuracy and stability of an intraoral scanner. Many clinics overlook regular calibration after purchasing a device, only to experience gradual declines in scanning precision without understanding the cause.
Calibration Principle
During daily use, the internal optical components of an intraoral scanner can experience slight displacement or thermal drift caused by temperature changes, mechanical vibration, or accidental impacts. These micro-changes shift the three-dimensional coordinate reference.
The calibration process uses a calibration object (calibration plate or block) of precisely known dimensions. The scanner measures this object and compares the results against the known standard values. It then calculates a correction matrix and updates its internal parameters, restoring the device to factory-level accuracy.
Recommended Calibration Frequency
Routine use: Perform a full calibration approximately every two weeks.
After moving the device: Calibrate immediately if the scanner is transferred between rooms or if the cart experiences bumps or vibration.
Significant temperature changes: Calibrate when room temperature fluctuates noticeably (for example, after turning air conditioning on or off).
When accuracy issues appear: If restorations repeatedly show seating problems or poor marginal fit, check the calibration status first.
Follow the manufacturer's guidelines: Calibration intervals vary by brand. Always prioritize the recommendations in the official user manual. Some newer systems (such as certain 3Shape TRIOS 5 configurations) claim factory pre-calibration and reduced need for user intervention, yet periodic verification is still advisable.
Calibration Best Practices
Ensure the scanner tip lenses are clean, free of debris, and free of scratches before starting.
Store the calibration object carefully in its protective dust bag; avoid drops and dust accumulation.
Perform calibration at room temperature. Allow the device to warm up for 10–15 minutes after powering on.
Follow the on-screen prompts carefully, placing the scanner tip correctly into the calibration object and keeping it stable until the process completes.
If calibration fails, do not repeatedly attempt it. First check cleanliness of both the lenses and the calibration object, then contact technical support if needed.
Some advanced systems include temperature sensors and automatic compensation algorithms that can correct thermal drift within a limited range. However, these features do not fully replace periodic manual calibration.
Why Regular Calibration Matters for Clinical Results
Consistent calibration helps maintain the scanner's trueness and precision over time, reducing the risk of undetected accuracy drift that can lead to remakes, poor-fitting restorations, or wasted chair time. It is one of the simplest yet most effective ways to protect your investment in digital dentistry.
