How many years must study models/casts be retained after treatment completion?

The requirement to retain study models or casts for six years after treatment completion is grounded in the need for adequate documentation and potential legal considerations in dental hygiene practice. This retention period ensures that practitioners have access to the physical records of a patient's treatment for a significant duration that aligns with standard statutes of limitations in many jurisdictions, which often range around six years. Keeping these records helps protect both the patient and the provider should any issues or disputes arise regarding the treatment provided.

This retention assures continuity in care and allows for reference in case a patient returns for further treatment. It also plays a role in quality assurance and can be vital for maintaining accurate health records. Thus, retaining study models or casts for six years represents a balanced approach between operational feasibility for the dental practice and the protective measures required for patient care.
