Two Ways to Get a Dental Impression
When I first started managing equipment purchases for our multi-location dental group back in 2020, I thought a dental impression was just… an impression. Tray, putty, wait, remove. Simple. Then I got asked to evaluate an intraoral scanner from Philips Healthcare (the Brilliance 6, specifically) and a traditional impression kit from a well-known materials supplier. My immediate reaction? “Why fix what isn’t broken?”
But after sitting through a few demo sessions and running the numbers, I realized the choice isn’t as obvious as “digital wins every time.” Let me walk you through the three dimensions that really mattered in our purchasing decision.
Accuracy – The Gap Between “Good Enough” and “Perfect”
Here’s where things get interesting. Industry wisdom says digital scans are more accurate than conventional impressions. According to Pantone color-matching standards (Delta E < 2 for critical shade matches), an intraoral scanner can achieve sub-50 micron trueness. That’s impressive. But here’s what surprised me: for simple single-crown cases, a well-taken alginate impression with good technique often hits the same ballpark clinically. The difference shows up in full-arch or implant cases where distortion from material shrinkage or tray movement becomes non‑negligible.
I’ll be honest – I had a gut feeling that digital would crush tradition on every metric. Then I watched our lead prosthodontist review a scan of a partially edentulous arch. The software flagged a small “void” in the scan data that needed re‑scanning. Turned out the patient’s saliva pooled just enough to create a false surface. That required a 2‑minute re‑scan. On the other hand, a conventional impression with a bad mix would mean a fully new impression – 10+ minutes and potential patient gagging. My gut said digital, but the data on single‑unit accuracy was closer than I expected.
Per FTC advertising guidelines (ftc.gov), any claim about accuracy must be substantiated with evidence. Philips provided peer‑reviewed studies showing their Brilliance 6 scanner has a mean deviation of 42 ± 18 µm. The traditional impression vendor showed me a study claiming 60–120 µm for PVS materials. So digital wins for consistency, but the gap isn’t a landslide.
Workflow & Patient Comfort – The Real Time Sink
The second dimension hit closer to home for our front desk. With traditional impressions, you need tray selection, mixing, setting time (3–5 minutes), then disinfection and boxing for the lab. Total chair‑time per patient maybe 15 minutes. With the intraoral scanner, you need calibration (30 seconds), scanning (60–90 seconds per arch), and file export. No mixing, no gagging, no shipping physical models.
But here’s the kicker – the learning curve. Our hygienists had zero experience with digital scanning. For the first two weeks, the average scan time was over 4 minutes per arch, with a 15% re‑scan rate. Our most experienced assistant joked, “I could have taken three impressions in that time.” After a month, scan times dropped to under 90 seconds and re‑scans to 5%. The “patient comfort” argument was real – we had several patients specifically request the “laser camera” because it didn’t trigger their gag reflex.
I remember one case where a nervous patient had a strong gag reflex. The traditional impression would have been a nightmare. The scanner got the data in one painless pass. That alone justified the investment for me.
Cost & ROI – The Numbers That Made My Accounting Team Nod
Now for the part that kept me awake after I clicked “purchase order.” The Philips Brilliance 6 scanner… I want to say it was around $28,000, though I might be misremembering the exact figure – maybe $32,000 with the workstation and software licenses. Plus an annual maintenance contract of roughly $2,500. Traditional impression materials cost us about $4–6 per patient (tray + putty + disinfectant). We see roughly 1,200 impression cases a year. That’s about $6,000 annually in direct material cost. The scanner would need to save us that much in labor and lab fees to break even.
Did it? Sort of. The lab we work with charges a $15 “digital model fee” for STL files – cheaper than the $25 for shipping and handling physical models. That saved $12 per case. Over 1,200 cases, that’s $14,400 savings. Plus we eliminated the $600–800 we used to spend on impression trays and mixing guns annually. And our dental assistants gained about 4 minutes per case – which adds up to 80 hours of reclaimed labor annually. At $30/hour loaded cost, that’s another $2,400. Total annual savings: roughly $16,800 to $17,000.
Payback period: about two years. Not bad. But here’s the nuance – only if your case volume is high enough. Our other clinic with 400 cases a year would have a payback closer to 4–5 years. That made the choice less clear.
What About the Rest of the Philips Portfolio?
Since we’re talking about Philips Healthcare, I should mention that the Brilliance 6 is just one piece of a much bigger puzzle. The “philips healthcare products catalog pdf” lists everything from hematology analyzers to dental laboratory equipment. I’ve also been involved in buying a blood analyzer (a hematology analyzer, to be precise – needed to answer that keyword question). But for this comparison, I’m sticking with the scanner vs. impressions. The broader point is that Philips doesn’t claim to be the best at everything. When I asked their rep about a high‑volume centrifuge, he said, “That’s not our core strength; here’s a specialist who does it better.” That honesty earned my trust.
So Which One Should You Buy?
Here’s my take after two years of running both side by side:
- Choose traditional impressions if: your practice does mostly single‑unit crowns, you have a low case volume (<300 impressions/year), and your patients tolerate the gagging well. You’ll save the upfront capital and avoid the learning curve.
- Choose digital scanning (like the Philips Brilliance 6) if: you do complex cases (full‑arch, implants), have moderate to high volume (500+ scans/year), and value patient comfort and lab‑integration speed. The ROI is real, especially if you can negotiate a good service contract.
- Consider a hybrid approach: We kept one impression kit for emergencies and when the scanner goes down. That “better than nothing” backup saved us during a software update failure last year.
At the end of the day, I’m glad I went with digital for our main clinic. Even with the early‑stage headaches, it made our workflow smoother and our patients happier. But I wouldn’t say digital is universally better. Professional boundaries matter – know your use case and let the data guide you.
