Digital dental lab workflow is at the center of one of dentistry’s most exciting transformations — and two of its most experienced practitioners break it all down in this episode of The Technology Evangelist Podcast. Host Dr. John Flucke welcomes Jorge Alegre, CDT, Founder of Digital Dental Hub and Co-Founder of Dental Kronicles, and Paolo Lubrano, MDT, a master dental technician specializing in implant prosthetics, for a wide-ranging conversation covering how digital dental lab workflow has transformed everything from single-unit crown prep quality to full-arch implant delivery timelines — and where 3D printing is taking the profession next.
Key Insights on Digital Dental Lab Workflow and 3D Printing in Dentistry:
- Two Unexpected Paths to the Dental Lab: Neither guest arrived at dental technology in a straight line. Paolo began as a clinical dentist in Italy — drawn first to cardiology, then oral surgery — before falling in love with ceramics and lab work during his clinical training and eventually making the full transition to the bench. Jorge came from criminal justice, mechanics, and automotive rally work before a summer job at his family’s Michigan dental lab in 2003 became a full career, shaped by early mentorship in CAD/CAM and the Sirona ecosystem through mentor Frank Costa of East Lab.
- Labs Make Dentists Look Good — and Dentists Often Don’t Know It: Jorge and Paolo are candid about what clinicians rarely see: dental labs regularly compensate for imperfect data. Dr. John Flucke cites a study finding that approximately 65% of analog impressions sent to labs contained some type of error — yet most of those crowns still didn’t fail, because skilled technicians found ways to work around the problems. In the era of digital dental lab workflow, “what you see is what we get” has changed that dynamic: the quality of the scan is now the foundation that everything else is built on.
- Intraoral Scanners Expose Prep Quality in Real Time: One of the most powerful side effects of the shift to digital has been making clinical prep quality immediately visible. Paolo recalls a dentist who scanned a crown preparation for the first time, then called to say he had never realized how poor his margins had been — and whose prep quality improved significantly once he could evaluate his own work on-screen. The digital dental lab workflow doesn’t just accelerate delivery; it creates a feedback loop that raises clinical standards over time.
- Tissue Management Is Still the Foundation: Digital tools haven’t eliminated the fundamentals. For a digital dental lab workflow to succeed, Jorge explains, proper tissue management remains non-negotiable: single- or double-pack retraction cord keeps tissue displaced and the field dry, giving the scanner the access it needs to accurately capture the margin. Without it, even the best CAD/CAM design is built on flawed data. For patients where bleeding or anatomy makes digital capture difficult, conventional impressions can still be digitized after the fact — preserving workflow continuity without sacrificing accuracy.
- Full-Arch Implant Cases: From Seven Appointments to Two: A traditional full-arch restoration — All-on-X, All-on-Four, or similar — could require six or seven appointments using analog methods: custom trays, open-tray impressions, verification jigs that sometimes don’t fit and need to be redone, and multiple setup visits. With digital tools including photogrammetry and intraoral scanning, Jorge describes compressing that same treatment into as few as two visits. He frequently completes design work remotely from home while the clinician scans at the practice, delivering files directly to an in-office 3D printer — a model that was simply impossible a decade ago.
- Bite Opening Adjustments Take Two Clicks: One of the most concrete illustrations of how digital dental lab workflow eliminates rework is VDO (vertical dimension of occlusion) adjustment. Opening a bite by two millimeters conventionally required removing and remounting plaster models, remaking provisional restorations from scratch — a significant time and material cost at every step. Digitally, Jorge explains, the same change is two or three clicks followed by a reprint. Paolo adds that pairing leaf gauges with intraoral scanning allows precise, repeatable bite opening to be confirmed chairside before any design work begins.
- “Purgatory Restorations” and the Rise of Printable Resin: Dr. John Flucke introduces the concept of “purgatory restorations” — digitally printed resin restorations that sit between a temporary and a definitive crown, used to confirm esthetics, function, and bite before committing to a final. These are particularly useful for patients with financial constraints or complex esthetic demands. Paolo extends the concept to cosmetic cases: 3D-printed resin veneers can now be designed and produced in a fraction of the time required for hand-layered composite veneers, offering a more accessible esthetic option for patients who cannot yet afford ceramic alternatives.
- The Lab-Clinician Partnership Is the Key Variable: Across this conversation on digital dental lab workflow, both guests return to the same core principle: the relationship between the lab and the clinical team is the single greatest determinant of predictable outcomes. Jorge describes it as a marriage — built on daily communication, shared data standards, and the trust required to catch problems early and course-correct quickly. Dr. John Flucke echoes this, noting that some of the most valuable clinical education of his career came not from paid CE courses but from ten-minute phone calls with lab technicians who had seen the same case type dozens of times.
- Where Digital Dental Lab Workflow Is Headed: Looking five years out, Paolo and Jorge see 3D printing continuing its advance into higher-tier clinical applications — resins growing stronger and more esthetic, and potentially challenging milled restorations across a wider range of indications. Zirconia isn’t going anywhere for definitive posterior cases, they note, but it is no longer the only serious material option for final restorations. Both guests — who met while beta testing CAD software in 2021 and have collaborated closely ever since — continue to push the field forward through hands-on continuing education and industry events, working to close the communication gap between what labs see every day and what clinicians may not yet realize is possible.
What Jorge Alegre and Paolo Lubrano make unmistakably clear is that digital dental lab workflow is never a solo achievement. It is a shared responsibility built on clean data, honest communication, and a clinical team willing to understand what the lab actually needs to deliver excellent work. The dentists who invest in that partnership — who call their lab before sending a complicated case, who learn to read their own scans critically, and who treat their lab technician as a collaborator rather than a vendor — are the ones who will get the most out of the digital tools now available.
