Electronic Lab Prescription — How Digital Workflow Eliminates Communication Errors

The paper lab prescription has remained largely unchanged for decades: a form filled out in the dental office, sometimes pre-printed, sent with the case to the lab, and manually entered into the system by a technician. Each of these steps is a point where information can be distorted, lost, or misinterpreted. An electronic lab prescription eliminates most of these risk points. At deltalabs., every prescription enters a digital system — a structured form, a complete change history, real-time status tracking. There are no more lost papers, miswritten numbers, or abbreviations that "everyone knows what they mean" in the office but no one in the lab understands.

The Problem with Paper Prescriptions

A paper prescription is an unstructured document — each office fills it out in its own way. The lab technician must interpret abbreviations and conventions specific to each dentist. This generates errors:

• Illegible handwriting — a submitted paper, the lab tech reads "crown" instead of "crown"; "m" or "n" are difficult to distinguish under a fax.
• Unclear abbreviations — the dentist writes "PL pal" thinking of a specific preparation, the lab technician doesn’t know what it means.
• Missing information — the dentist thought "it’s obvious," but what’s obvious to them isn’t always obvious to the technician (cement shade, veneer thickness, cementing type).
• No modification history — the dentist called on Friday with a correction, but the paper form doesn’t reflect this change.
• Logistical loss — the paper gets lost in transit, on the lab technician’s desk, or somewhere in the archive.
• No documentation of "who changed what" — when an error occurs, it’s hard to determine if the instructions were understood correctly.

What an Electronic Lab Prescription Contains

An e-prescription is a structured form filled out in the lab portal. At deltalabs., it includes:

• Patient and order details: name, surname, ID number, acceptance date, completion date.
• Work specification: which teeth (1.1, 1.2, 2.1, etc.), what material (zirconia, e.max, metal-ceramic), shade (Vita scale, material sample), type of work (crown, bridge, veneer, telescopic crown).
• Digital files: intraoral scans (STL, PLY), reference photos, shade guide (if available).
• Clinical information: preparation description, adjacent tooth condition, questions for the CAD designer, potential medical limitations.
• Change history: every modification has a date, time, and the name of the person who made it.
• Real-time status updates: "Scan received," "CAD in progress," "Renders ready," "Awaiting approval," "Ready for shipment," "Shipped."

How the Order Portal Works at deltalabs.

After submitting an order (email, portal, phone), the dentist receives a unique access link to the portal. From the portal, the dentist can:

• Track the work status in real-time — knowing exactly what stage their order is at.
• Receive messages from the CAD designer — "Should I change the distal contact point by 0.5 mm?" or "Does Vita A1 or A2 material better match the antagonists?"
• Download and review project renders — approve or add comments directly in the portal.
• Review history — all previous orders, all communication exchanges, all design paths for the same patient (if they have subsequent teeth to restore).

The dentist doesn’t have to call to check the status — everything is available in the portal at any time. When approving a CAD design, the dentist confirms with a click — the change is recorded with a date, time, and authentication data.
