How Many Crowns Per Month Do You Need to Justify a CEREC® System?

For a dental practice considering CEREC®, one of the most important questions isn't simply "How much does a CEREC system cost?"

It's:

How many restorations do we need to produce each month for CEREC to make financial sense?

There isn't one number that applies to every dental office. A practice producing eight crowns per month with high laboratory costs can have a very different calculation from one producing 30 restorations per month with a low-cost lab.

But the calculation itself is relatively straightforward.

You need to compare what you're spending on outsourced restorative dentistry today with the cost of producing appropriate restorations in-house — and then determine whether the resulting savings and workflow benefits justify the investment in a chairside CAD/CAM system.

Here's how to evaluate it.

The Short Answer

For most practices, the more crowns, inlays and onlays that can realistically be moved from the dental lab to an in-house CEREC workflow, the easier it becomes to justify the investment.

But there is no universal rule such as "10 crowns per month makes CEREC profitable."

The real break-even point depends on:

• Number of eligible restorations per month
• Current laboratory fee per restoration
• Cost of CEREC blocks and other consumables
• Equipment purchase or financing cost
• Milling and finalization equipment being used
• Staff and doctor time required for the workflow
• Percentage of cases that will continue going to the laboratory
• How consistently the practice actually uses the system

Instead of starting with the price of the equipment, start with your current restorative volume.

Step 1: Calculate Your Current Crown and Restoration Volume

Look at the last 6–12 months of production.

Count the restorations that could reasonably be candidates for a chairside CAD/CAM workflow, including:

• Single crowns
• Inlays
• Onlays
• Selected veneers
• Other compatible single-unit restorations

Don't count every restorative case automatically. Some complex cases should continue to be handled by a dental laboratory.

For example, suppose a practice averages:

15 eligible restorations per month × 12 months = 180 restorations per year.

That annual number is more useful than looking at one unusually busy or slow month.

Step 2: Determine What You're Currently Paying the Dental Lab

Now calculate the actual laboratory cost associated with those restorations.

As an illustration, consider a practice paying an average of $150 per eligible restoration:

These figures are examples, not industry averages. Substitute your practice's actual lab fee to make the calculation meaningful.

This is one of the most important numbers in a CEREC ROI analysis because laboratory spending is a recurring expense.

Step 3: Don't Treat In-House Crowns as Free

Eliminating an outsourced lab fee does not mean the entire lab fee becomes profit.

A CEREC restoration still has production costs.

Depending on the restoration and workflow, these may include:

• CAD/CAM block
• Milling or grinding instruments
• Stain and glaze materials
• Furnace cycles where required
• Cementation materials
• Equipment maintenance
• Staff time
• Doctor design and finishing time

This is why a useful CEREC cost-per-crown calculation should use:

Current outsourced cost − actual in-house variable cost = potential savings per eligible restoration

Then:

Savings per restoration × eligible monthly volume = potential monthly production savings

That gives you a much more realistic starting point for evaluating the investment.

Step 4: Calculate Your Practice's Break-Even Volume

Here's a simplified example.

Assume:

• Current lab fee: $150 per restoration
• Estimated in-house variable production cost: $35
• Difference: $115 per restoration
• Monthly equipment cost allocated to the system: $1,500

The simplified break-even calculation becomes:

$1,500 ÷ $115 = approximately 13 restorations per month

Under those assumptions, approximately 13 eligible restorations per month would cover the $1,500 monthly equipment expense through the difference between outsourced and in-house production costs.

At 20 restorations:

20 × $115 = $2,300/month

At 30 restorations:

30 × $115 = $3,450/month

Again, these are illustrative numbers, not a promise of savings or profitability. Financing, taxes, labor, maintenance, material choice and actual lab costs can change the calculation substantially.

But this is the formula every practice can use with its own numbers.

CEREC ROI Calculator: A Simple Formula

You don't need sophisticated financial software to make an initial estimate.

Use:

A = Eligible restorations per month

B = Average outsourced laboratory cost per restoration

C = Average in-house variable cost per restoration

Then:

Monthly potential production savings = A × (B − C)

For example:

18 restorations × ($160 lab fee − $40 in-house cost) = $2,160/month

Annualized:

$2,160 × 12 = $25,920/year

Then compare that figure with the actual cost of acquiring, financing and maintaining the CEREC equipment you're considering.

Why Restoration Volume Matters So Much

A CAD/CAM system is a capital asset.

A practice that owns CEREC but sends nearly every restoration to a laboratory still carries the cost of the equipment without capturing much of its potential economic benefit.

Conversely, higher utilization spreads the fixed equipment cost across more restorations.

That's why asking "What does a CEREC system cost?" without asking "How often will we use it?" gives an incomplete picture.

The same CEREC system can be a very different investment for a practice producing five eligible restorations per month versus one producing 25.

The Financial Benefit Isn't Only the Lab Bill

Laboratory savings are the easiest part of CEREC ROI to calculate, but they're not the only consideration.

A traditional laboratory workflow can involve:

Appointment 1: preparation, impression or scan, provisional fabrication and provisional cementation.

Then the case is manufactured outside the practice.

Appointment 2: provisional removal, evaluation of the definitive restoration, adjustment and final cementation.

With an appropriate chairside CEREC workflow, selected restorations can instead be scanned, designed, manufactured and delivered in the practice.

Dentsply Sirona describes CEREC as an integrated chairside workflow in which restorations can be designed and manufactured in-office, with materials requiring heat treatment finalized using CEREC SpeedFire. The company states that Primemill's Super-Fast mode can mill certain zirconia crowns in around five minutes.

That creates potential operational benefits beyond the direct laboratory fee:

• Fewer provisional restorations
• Fewer second cementation appointments
• Greater control over manufacturing timing
• Less dependence on shipping and laboratory turnaround
• Ability to complete appropriate restorations in a single visit

The financial value of those benefits varies significantly by practice and shouldn't automatically be counted as cash savings.

What Does the Research Say About Digital Workflow Efficiency?

The evidence requires some nuance.

A systematic review examining time efficiency and cost in digital versus conventional fixed-prosthodontic workflows found that digital workflows can shorten portions of the laboratory process, although results for impression/scan time varied among studies. The authors also noted that more evidence is needed to properly evaluate cost-effectiveness.

That's important because purchasing CEREC shouldn't be justified with the assumption that digital automatically means cheaper in every situation.

The economics depend heavily on utilization.

Clinical evidence also supports the long-term viability of chairside CAD/CAM restorations. One study following CEREC-produced feldspathic posterior crowns reported estimated 12-year survival of 95% for molars and 94.7% for premolars.

The business case therefore shouldn't be based on producing a cheaper restoration at the expense of clinical performance. The objective is to determine whether an appropriate chairside workflow can provide the clinical result while improving the economics and workflow of the practice.

What If You Only Produce 5–10 Crowns Per Month?

Lower restorative volume doesn't automatically mean CEREC is the wrong investment.

But the justification becomes more dependent on other factors.

A lower-volume practice should ask:

Will restorative volume grow?

If the practice is actively expanding restorative dentistry, today's volume may not represent utilization two or three years from now.

Are you purchasing new or pre-owned equipment?

Acquisition cost dramatically affects the break-even calculation.

Are you buying a complete system or adding to equipment you already own?

A practice that already has a compatible scanner, milling unit or furnace has a very different investment calculation from one starting from zero.

How valuable is same-day dentistry to the practice?

Some practices value the workflow and patient experience enough that pure laboratory savings aren't the only deciding factor.

At low utilization, however, the financial argument based solely on eliminating lab fees becomes harder to make.

What If You Produce 20–30+ Restorations Per Month?

This is where the economics can become considerably more interesting.

Every additional eligible restoration allows the fixed equipment cost to be distributed over greater production volume.

At that point, the practice should evaluate not simply whether it can justify CEREC, but which CEREC configuration matches its production requirements.

A higher-volume practice may place greater value on:

• Faster manufacturing
• Automated workflows
• Broader material capabilities
• Reduced milling bottlenecks
• Newer-generation equipment

For example, the production requirements of a practice milling several restorations per day can be quite different from those of a practice producing several per week.

That distinction is exactly why we recently compared CEREC MC XL vs. Primemill: the right milling unit depends partly on production volume and workflow requirements.

CEREC vs. Dental Lab: It Doesn't Have to Be Either/Or

One of the biggest misconceptions about adopting chairside CAD/CAM is that the practice must stop using its dental laboratory.

It doesn't.

A productive model can be:

CEREC for appropriate routine chairside restorations + dental laboratory for cases where laboratory expertise adds value.

Complex anterior esthetics, extensive rehabilitations and certain implant or multi-unit cases may still benefit from laboratory involvement.

The objective isn't necessarily to eliminate your dental lab.

It's to determine which restorations make sense to control and manufacture inside your practice.

New vs. Pre-Owned CEREC Changes the Calculation

Equipment acquisition cost is one of the largest variables in the break-even equation.

That means practices shouldn't evaluate CEREC ROI without considering different acquisition strategies.

A new system may provide access to the newest hardware and workflows but requires a larger initial investment.

A properly configured pre-owned CEREC system can reduce the capital required to enter chairside CAD/CAM, which can substantially change the number of monthly restorations needed to justify the investment.

We've covered those differences separately here:

So, How Many Crowns Per Month Justify CEREC?

There isn't a responsible universal number.

But there is a responsible way to find your number.

Start with:

1. Your actual monthly eligible restoration volume
2. Your actual average laboratory fee
3. Your estimated in-house variable production cost
4. The actual acquisition or financing cost of the CEREC configuration you're considering
5. The percentage of cases you realistically intend to manufacture chairside

Then calculate:

Monthly eligible restorations × savings per restoration

and compare that result with your monthly equipment cost.

That's your starting point.

A practice producing 5 restorations per month may have difficulty justifying a large equipment investment purely through laboratory savings.

A practice producing 15–20 restorations per month may find the calculation substantially more attractive depending on lab costs and equipment price.

And a practice producing 20–30+ eligible restorations per month should pay particular attention to workflow capacity and milling speed in addition to acquisition cost.

The key isn't finding somebody else's break-even number.

It's calculating yours.
