A digital dental lab workflow replaces the physical impression with an intraoral scan, sends that file to the lab through a scanner portal or as an STL or OBJ export, and lets the lab design, mill or print, and finish the restoration from the same data. Practices can realistically expect faster case intake, fewer shipping steps and earlier questions from the lab. What they should not expect is a shortcut around quality control: the scan, the prescription and the shade information still decide how well a crown or implant restoration fits.
For practice owners and office managers, the shift reaches beyond the operatory. It changes how cases are scheduled, how the front desk tracks what is out at the lab, and what the clinical team checks before a file leaves the building. Here is what each stage looks like and where practices tend to lose time.
Step One: Connecting the Practice’s Scanner to the Lab
The digital dental workflow starts before the first patient is scanned. The scanner has to know where to send files, and most manufacturers handle that through a lab connection inside their cloud portal. In practice, that usually means entering the lab’s case email address or company ID once, after which the lab appears as a destination in the export menu.
Labs differ in how much of that setup they take off the practice’s plate. RSU – Reliable Dental Studio’s digital scanner program, run by a family-owned, full-service dental laboratory founded in 1994 with labs in Rosemead, California, Lakewood, Colorado, and Round Rock, Texas, connects through the portals of iTero, 3Shape TRIOS, Medit and Carestream scanners and also accepts STL or OBJ exports by email.
Implant Cases: Why the Scan Has to Carry More Information
Implant work is where a complete digital submission pays off most. Unlike a natural tooth preparation, an implant case needs the exact implant position and the components involved, which is why the scan is taken with a scan body seated on the implant. The prescription should name the implant brand, platform and diameter, the preferred retention (screw- or cement-retained) and the scan-body type.
When dentists order implant restorations from RSU – Reliable Dental Studio, for example, the lab asks for exactly those details and verifies the components against the manufacturer’s specification before design begins; on request, the CAD design is shared with the dentist for approval. A scan without the scan-body type or a platform note usually leads to a call from the lab before anything can be designed, so filling in those fields at the chair saves a day later.
How Common Are Intraoral Scanners in U.S. Practices?
Intraoral scanning has moved well beyond early adopters. In a 2021 report from the American Dental Association’s Clinical Evaluators (ACE) Panel, based on responses from 369 member dentists, 53% said they use an intraoral scanner in their practices. Among users, 70% named improving clinical efficiency as their main reason for introducing it, and single tooth-supported crowns were the most common application. Among nonusers, 66% pointed to the high financial investment as the main barrier. The survey is a few years old, so adoption may well have shifted since, but it shows clearly what drives the decision.
“The integration of digital technologies in dentistry is unstoppable,” said Marta Revilla-León, D.D.S., one of the report’s co-authors, in the ADA News coverage of the findings.
What a Digital Case Looks Like From Scan to Seat
The stages below are typical for a fixed restoration sent digitally. Individual labs organize them differently, but the division of labor between practice and lab is broadly the same.
| Stage | Practice | Lab |
|---|---|---|
| 1. Scan and Rx | Scans the preparation, opposing arch and bite; completes the Rx with material, shade and photos | – |
| 2. Transfer | Sends the case through the scanner portal or as an STL/OBJ file | Confirms receipt and checks that scan and Rx are complete |
| 3. Design | Reviews the design if a preview was requested | Designs the restoration in CAD software from the scan and Rx |
| 4. Fabrication | – | Mills or prints, finishes and runs quality control |
| 5. Delivery and seat | Seats the restoration and reports back any adjustments | Ships the case with its documentation |
Speed is part of the appeal, but expectations should stay realistic. A 2020 meta-analysis by de Oliveira and colleagues in Clinical Oral Implants Research compared digital and conventional workflows for single implant crowns. It reported a statistically significant time reduction for the digital group, with a mean difference of 8.22 minutes, and cautioned that this difference may not be clinically relevant. In other words, the scan itself saves a little chair time; the bigger gains come from fewer remakes of lost or distorted impressions, no physical shipping of models and faster answers when something is unclear.
What the Practice Team Should Check Before Sending a Case
Most delays in a digital case start with something missing, not something wrong. A short pre-send check, done by the assistant who took the scan, catches the usual gaps:
- Margins are fully captured and visible, without gaps in the scan.
- The opposing arch and a bite registration are included.
- The Rx lists material, shade and, for implants, brand, platform, diameter and scan-body type.
- Shade photos are attached when the restoration is in the esthetic zone.
- The case is logged in the practice management system with the patient reference and the seat date.
That last point matters more than it seems. When the seat appointment is booked against a realistic lab timeline, rather than a guess, the front desk avoids reschedules and the patient gets one fewer phone call.
Choosing a Digital Lab Partner: Questions Worth Asking
Before committing to a digital dental lab workflow, practices should ask how a lab handles each step above. Which scanners connect directly, and which require manual exports? Who helps when an upload fails, and does the lab confirm that each case has arrived complete? How long are digital models stored after a case is completed? Are design previews offered, and for which types of cases? How are turnaround times quoted? Product-specific timelines are a better sign than one blanket number, because a single crown, an implant bridge and a full-arch case follow very different schedules. And who picks up the phone when a scan is incomplete: a sales contact or the technician working on the case?
None of these questions require a technical background. They give office managers and dentists a shared checklist for comparing labs on the things that affect the schedule, not just on materials and price.
Frequently Asked Questions
What file formats do dental labs accept from intraoral scanners?
STL is the most widely accepted format for intraoral scans. Many labs also accept OBJ or PLY files, which can include color information that helps with shade communication. Most scanner portals export the right format automatically when the lab is connected.
Does a digital workflow eliminate remakes?
No. It removes some sources of error, such as distorted impression material or damaged models in transit, but scan quality, visible margins and a complete prescription still determine the fit. A lab that asks questions before design is a good sign, not a delay.
Can a practice work with a digital lab without owning a scanner?
Yes. Many digital labs still accept conventional impressions and process them in-house. A scanner makes case transfer faster, but it is not a requirement for working with a lab that uses CAD/CAM fabrication.
How long does a digital dental lab case take?
It depends on the restoration. Single-unit crowns, implant restorations and full-arch cases follow different schedules, so practices should ask the lab for turnaround times per product rather than one general figure, and book the seat appointment accordingly.
