2025 Warranty Update
At True Function Laboratory, we stand behind the quality of every device we make. That’s why all our devices are backed by a warranty — if a device doesn’t meet expectations, we’ll make it right. Whether that means repairing or replacing it, we’re here to support your practice with consistent quality and peace of mind.
To help us do that, we ask that you return the original device along with the original models or impressions and bite registration (if used). If the issue involves changes in anatomy or model distortion, we may request updated materials to ensure the best possible fit. Our goal is always to reproduce the original design and prescription — quickly, reliably, and without hassle.
While our warranty does not cover issues related changes in the patient’s dentition, damage from misuse, or third-party modifications, we promise to handle each request with care and urgency. Retention concerns that are reported more than 90 days after delivery are not covered, as clinical or anatomical changes may impact long-term fit. If a new device is ordered while the original is being returned or under review, it will be invoiced until warranty eligibility is confirmed. No matter the situation, our team is here to help — because standing behind our work is what defines us.
