Buying a certified pre-owned cone beam CT (CBCT) system can be one of the smartest investments a dental practice makes.
The right system can provide years of dependable diagnostic performance while saving tens of thousands of dollars compared to purchasing new equipment.
But not all used CBCT systems are created equal.
Unlike buying a new system directly from a manufacturer, purchasing pre-owned equipment requires asking the right questions before making a decision.
At Renew Digital, we've purchased, inspected, refurbished, and installed thousands of dental imaging systems. Every machine that enters our inventory goes through a detailed evaluation process before we ever consider offering it to another practice.
Whether you're purchasing from Renew Digital or evaluating equipment elsewhere, here are seven questions every dentist should ask before buying a used CBCT.
This should always be your first question.
A CBCT system is a sophisticated piece of medical equipment—not simply a used piece of office furniture.
Before purchasing, ask:
A reputable imaging specialist should be able to explain exactly how the system was evaluated before offering it for sale.
If the seller can't answer those questions, consider it a red flag.
Excellent hardware doesn't mean much if the software is outdated.
Ask:
Software compatibility often determines how easy a system will be to own over the next several years.
One of the biggest differences between buying from an imaging specialist and purchasing equipment through an auction or broker is installation.
Ask:
Even an excellent CBCT system can underperform if it's not properly installed and calibrated.
A warranty says a great deal about the confidence a company has in its equipment.
Ask questions such as:
The lowest purchase price isn't always the lowest ownership cost.
A strong warranty often provides far greater value than saving a few thousand dollars upfront.
This question is frequently overlooked.
Even excellent CBCT systems require occasional maintenance over their lifetime.
Before purchasing, ask:
A system is only as valuable as the support standing behind it.
Every used equipment package is different.
Some include everything necessary for installation.
Others require significant additional purchases.
Clarify exactly what's included:
Understanding the complete package helps eliminate unexpected costs later.
This may be the most important question of all.
Not every company selling used dental equipment specializes in imaging.
Some companies sell:
Others, like Renew Digital, focus exclusively on dental imaging.
That specialization matters.
Working with an imaging-focused company often means access to:
When you're making one of the largest technology investments in your practice, expertise matters.
Many dentists begin shopping by asking:
"What's your best CBCT?"
A better question is:
"What's the best CBCT for my practice?"
The answer depends on several factors:
The best imaging specialists don't simply recommend the most expensive system.
They recommend the system that best supports your clinical and financial goals.
As you evaluate used CBCT systems, proceed carefully if you encounter:
Remember:
If a price seems dramatically lower than every comparable system on the market, there's usually a reason.
More dentists are embracing certified pre-owned imaging because it offers an opportunity to purchase premium technology at a significantly lower cost.
When purchased through a trusted imaging specialist, certified pre-owned equipment can provide:
For startups, expanding practices, satellite offices, and growing specialty practices, it has become one of the smartest ways to invest in advanced imaging.
Buying a used CBCT shouldn't feel like taking a gamble.
It should feel like making an informed investment.
By asking the right questions—and working with an experienced imaging partner—you can confidently choose a system that will support your practice for years to come.
At Renew Digital, these aren't just questions we recommend.
They're the same questions we ask ourselves before every imaging system becomes part of our certified inventory.
Because when it comes to dental imaging, confidence starts long before the first scan.
