You calculated the ROI on your dental lab relationship. On average, a crown costs $150. Bridge costs = $300-$450. The math seemed straightforward.
But when you factor in remakes, rush fees, shipping, and failed temporaries, that ROI calculation falls apart and makes accurate budgeting difficult.
As a result, most practices focus on per-unit lab costs. Those numbers are visible and easy to track. But other costs are lurking that you can’t see—costs that cascade when that crown doesn’t fit, when you need a rush turnaround, or when a temporary fails before the permanent arrives.
These hidden lab costs are quietly killing your practice’s profitability. Here’s exactly how much they’re costing you—and how to eliminate them.
The Remake Reality
According to Spear Education, the national average for dental laboratory remakes in the U.S. is 4%, with a range of 1% to as high as 6-7%.
That might not sound alarming. Four percent? That’s a 96% success rate, right?
But consider what that actually means for a typical practice doing 20 crowns per month:
- 240 crowns per year × 4% remake rate = ∼10 remakes annually
And then, there’s this: an NCBI survey shows that nearly one-fifth of dentists reported having a remake rate of more than 4%. Many practices operate significantly above the national average without tracking the data accurately.
The True Cost of a Single Remake
When a crown doesn’t fit and requires a remake, here’s what actually happens:
The Direct Costs
Scheduling a second appointment means lost production time. Your staff spends time rescheduling. The remake itself often carries lab fees—some labs cover remakes, but many charge 50-100% of the original fee. Shipping costs another $15-30 each direction. Another temporary adds more materials cost.
The Opportunity Costs
That open chair time, waiting for the remake? You could be using that time to see new patients. Those patients who had a poor experience? They’ll be less likely to accept comprehensive treatment plans. And you’re managing the situation rather than focusing on clinical care.
The Patient Experience Costs
When a restoration doesn’t fit, patients lose trust—even when it’s clearly a lab error. You might see negative reviews mentioning “multiple visits” or “didn’t fit right.” That patient becomes more likely to shop around. In the worst cases, you lose the patient entirely.
Quantifying One Remake
Spear Education data shows that the average dental practice has overhead expenses of 70-80% of revenue, translating to approximately $375 per hour in overhead costs.
Cost Breakdown for One Crown Remake:
- Remake lab fee (50% of original): $75
- Additional temporary materials: $10
- Shipping costs (round trip): $30
- Staff time (30 minutes): $25
- Remake appointment chair time (45 minutes): $280
- Total cost per remake: $420+
For a practice with 10 remakes per year, that’s $4,200 in direct remake costs buried in lab fees, supply costs, and overhead.
The Compound Effect of Rush Fees
You have a patient scheduled for final crown delivery tomorrow. The doesn’t fit. You can’t reschedule—the patient has taken time off work.
So you call the lab. “Can you rush this? I need it tomorrow.”
“Sure. 50% rush fee.”
Rush fees typically range from 50-100% premium. A $150 crown becomes $225-300. A $300 bridge becomes $450-600.
Annual rush fee expenses:
- 12 rush crowns × $75 premium = $900/year
- 2 rush bridges × $150 premium = $300/year
- Misc rush fees = $400/year
- Total: $1,600+
You’re paying premium prices to fix problems that often stemmed from the original lab work not being right.
The Failed Temporary Problem
Between prep and delivery, your patient wears a temporary. And unfortunately, temporaries sometimes fail—they pop off, fracture, or cause discomfort. If it fails, guess what? That’s another appointment.Â
Emergency Temporary Repair Costs:
- Unscheduled emergency appointment
- Staff time coordinating coverage
- Materials to re-cement or fabricate new temporary
- Patient dissatisfaction
- Lost revenue from bumping scheduled production
For practices doing same-day dentistry with chairside 3D printing, this entire category of costs disappears. No temporaries means no temporary failures.
Shipping: Death by a Thousand Small Charges
Shipping seems minor. $15 to send. $15 for return. $30 per case.
But multiply across all lab cases:
- 20 crowns/month × $30 shipping = $600/month = $7,200/year
- Remakes and rush cases add $500-1,000/year
- Total annual shipping: $7,700-8,200
You’re paying thousands yearly for the privilege of waiting 1-2 weeks.
Chairside 3D printing can eliminate these shipping costs.
The Digital Impression Advantage
Research shows digital impression systems markedly improve restorative outcomes, with remake percentages typically going down significantly for both the dentist and technician.
Labs report remake rates below 1% for digitally initiated cases, compared to 3-4% for traditional impression methods.
In layman’s terms: If you’re still using traditional impressions, you’re increasing your remake rate by 2-3%.
The Opportunity Cost of Lab Dependency
Beyond direct costs, there’s a larger strategic cost: lost chair time.
The Efficiency Impact
When a crown takes 10-14 days at the lab, that’s 10-14 days your patient could have had their final restoration. Two appointments are required instead of one. Scheduling coordination increases complexity. Open cases create administrative overhead. Patients rescheduling delivery appointments extend the timelines even further. Overall, it’s simply a dated, poor customer experience.Â
The Production Impact
Appointment slots used for deliveries could be used for production. A 30-minute delivery appointment generates minimal revenue compared to a 90-minute new crown start.
If you eliminated delivery appointments and used those slots for productive procedures:
- 15 delivery appointments per month × 30 minutes = 7.5 hours per month
- At $400/hour production (conservative), that’s $3,000/month = $36,000/year in additional production capacity
The Chairside Solution
Here’s where chairside 3D printing with SprintRay Pro 2 fundamentally changes the economics.
What Disappears
Remake fees: $0 (you control quality before delivery).
Rush fees: $0 (you control timeline).
Shipping: $0 (print on-site).
Failed temporary appointments: $0 (no temporaries with same-day workflow).
Second delivery appointments: $0 (complete treatment in one visit).
What Remains
Material costs for printing: ~$5-15 per restoration. Your time for design and production: integrated into a single appointment workflow.
What You Gain
Complete quality control—you verify before the patient leaves, giving you the ability to offer same-day patient satisfaction. Add reduced scheduling complexity and you’ve freed up chair time for additional patients while eliminating patient dropout between appointments. Your workflow becomes streamlined and optimized.
The Real Numbers
Annual costs for a practice doing 20 crowns per month:
Traditional Lab-Dependent Costs:
- Base lab fees (240 crowns × $150): $36,000
- Remake costs (10 remakes × $420): $4,200
- Rush fees: $1,600
- Shipping: $7,500
- Failed temporary emergencies: $1,500
- Total: $50,800
Chairside 3D Printing Costs:
- Material costs (240 crowns × $10): $2,400
- Pro 2 Protection Plan: $1,750
- Total: $4,150
Annual Savings: $46,650
That’s not accounting for the opportunity cost of freed chair time or improved patient satisfaction.
What About Lab Expertise?
A common objection: “My lab technician has decades of experience. How can I match that quality in-house?”
Technology Levels the Playing Field
For appropriate cases, AI-powered design software like SprintRay’s AI Studio guides you through crown design with automated margin detection, contact point optimization, and occlusion analysis. You’re leveraging AI to replicate lab expertise for routine work.
Strategic Lab Relationships Still Matter
Full-mouth reconstructions, complex aesthetic cases, and multi-unit bridges with precise implant angulation still benefit from experienced lab technicians. The solution isn’t eliminating labs—it’s using them strategically while bringing routine restorative work in-house.
Quality Control Stays With You
Whether a crown comes from a lab or is printed chairside, you seat it and take responsibility. With chairside production, you verify fit before the patient leaves. That’s better quality control than hoping the lab got it right.

The Bottom Line
You budget for lab fees. But you’re not budgeting for remake appointments eating productive chair time, rush charges when cases come back wrong, shipping costs compounding month after month, failed temporaries requiring emergency appointments, lost chair time waiting on lab turnaround, patient dissatisfaction from multiple visits, or opportunity costs of delivery appointments.
These hidden costs compound annually into tens of thousands of dollars that never appear clearly on financial statements—but they’re absolutely impacting profitability.
Chairside 3D printing isn’t just about saving money on lab fees. It’s about eliminating an entire category of hidden costs while improving patient experience and practice efficiency.
