QUB3 – Frequently Asked Questions
Do you have any questions about the QUB3 masticatory assessment system?
Find all the answers here.
1. Why should I measure masticatory function if no one is currently asking me to?
Because mastication is one of the primary functions of the stomatognathic system and is closely linked to health, longevity, and quality of life. Just as we measure blood pressure, vision, or hearing, we should also be able to measure masticatory function.
2. What does QUB3 measure?
QUB3 objectively measures masticatory function. In other words, it measures how effectively a patient is able to chew.
3. Which patients should I use QUB3 with?
All patients. Masticatory function is relevant to every individual, not only to those who require rehabilitation.
4. What can I do with the value I obtain?
The value is the starting point. When integrated into the Masticatory Function Charting in my.QUB3, it turns a simple measurement into clinically useful information that helps the clinicians understand, monitor, and communicate the patient’s functional status.
5. What is considered a normal value?
In general, a VoH below 0.300 is associated with good masticatory function. Higher values may indicate reduced functional performance and warrant further clinical assessment.
As with any biological parameter, the result should always be interpreted within the patient’s clinical context
6. Can QUB3 be used to make a diagnosis?
No. QUB3 measures a biological function. Diagnosis remains the responsibility of the clinician.
7. Why isn’t it enough to simply ask patients whether they chew well?
Because perception and function do not always correspond. Many patients report that they chew well despite having impaired masticatory function.
8. How long does the test take?
Less than one minute. After 20 chewing cycles, the result is immediately available.
9. Is the Two-Color Mixing Ability Test scientifically validated?
Yes. It is one of the most extensively studied and validated methods for assessing masticatory function.
10. How reliable is the result?
QUB3 standardizes the testing and analysis process. Studies have demonstrated high repeatability and reproducibility of the method.
11. If I obtain a value within the physiological range despite the presence of clinical problems, how should I interpret it?
Function is only one dimension of oral health. A good result indicates that the patient maintains good masticatory function, but it does not rule out the presence of conditions requiring diagnosis and treatment.
12. If I obtain a worse result after treatment, how should I interpret it?
Anatomical recovery and functional recovery do not always coincide. Just as rehabilitation and physiotherapy may be needed after orthopaedic surgery to restore function, the stomatognathic system may also require time to adapt and reach its full functional potential.
