What is a dental lab prescription?

A dental lab prescription is the written order a dentist sends with a case to the lab, specifying the restoration type, tooth numbers, material, shade, occlusal scheme, margin design, and return date. It travels with the impression or intraoral scan file and serves as the legal record of what the clinician authorize...

THE SHORT ANSWER

THE FULL PICTURE

Why it works this way

The legal definition

A dental lab prescription, sometimes called a lab slip or work authorization form, is the written directive a licensed dentist issues to a registered dental laboratory authorizing fabrication of a specific restoration or appliance. Per the American Dental Association's Council on Dental Practice guidance and state-level dental practice acts (California Business and Professions Code Section 1656, for example), the prescription is a legal document and must be retained by the lab for a minimum period, typically two to seven years depending on jurisdiction.

Is a dental lab prescription legally required?

Yes, in every U.S. state. State dental practice acts require a written prescription from a licensed dentist before a registered dental laboratory may fabricate a restoration or appliance. The lab must retain the prescription for a defined period, commonly two to seven years depending on the state. Verbal orders without written follow-up are not compliant. Both the prescribing dentist and the receiving lab share record-keeping obligations, and state dental boards routinely audit lab prescription files during inspections.

What happens if the prescription is incomplete?

An incomplete prescription forces the lab to either pause the case and contact the office for clarification or proceed on assumption, which is the most common origin of remakes. Missing shade, unspecified margin design, and unclear occlusal preferences are the top three offenders. At Dani Dental the assigned technician contacts the practice the same business day a gap is identified rather than guessing, which keeps the case on its original return date instead of triggering a rework cycle.

Can a dental lab prescription be sent digitally?

Yes. Digital prescriptions submitted through intraoral scanner portals (3Shape Communicate, iTero MyAligntech, Medit Link) or as PDFs paired with STL or PLY scan files carry the same legal weight as paper. Most scanners enforce required fields before submission, which cuts the missing-data remake rate substantially. The dentist still signs, electronically, and the lab retains the digital prescription under the same retention rules that apply to paper. Hybrid workflows (digital scan plus paper Rx) remain common and fully compliant.
