APPENDIX 6: True Function Limited Warranty and Disclaimer
True Function Laboratory guarantees that our appliances are constructed to your prescription specifications, will fit the working model provided or the working model created from the impression provided, and be free of defects in materials and craftsmanship.

If a new appliance is ordered during the evaluation of the defective appliance or while being worn by the patient until the new/repaired one is delivered, there will be a full charge for the replacement appliance.
