Shopping for a cone beam CT (CBCT) system can feel overwhelming.
One manufacturer advertises a smaller voxel size. Another highlights faster scan times. A third emphasizes AI-powered software, while another focuses on field of view options.
Every brochure promises exceptional image quality.
Every sales representative says their machine is the best.
So how do you actually compare two CBCT systems?
The answer isn't by reading spec sheets alone.
At Renew Digital, we've helped thousands of dentists evaluate imaging systems from virtually every major manufacturer. One of the biggest misconceptions we see is that buyers often compare technical specifications before they compare how the machine will actually perform in their practice.
The truth is, there is no universally "best" CBCT machine.
There is only the best CBCT for your practice.
Here's how imaging specialists compare systems—and how you can, too.
Before comparing brands or models, ask yourself a more important question:
What do I need this machine to do?
A CBCT that's perfect for an endodontist may not be the best choice for an orthodontic practice.
Your specialty, patient volume, and long-term goals should guide your decision long before you compare specifications.
For example:
General Dentistry
Orthodontics
Endodontics
Oral Surgery
Understanding your clinical priorities helps eliminate machines that simply aren't the right fit.
One of the most common mistakes buyers make is focusing on a single specification.
Maybe it's voxel size.
Maybe it's scan time.
Maybe it's the number of field-of-view options.
While each specification has value, no single number tells the whole story.
Think of buying a CBCT like buying a car.
Horsepower matters—but so do safety, reliability, comfort, fuel economy, and resale value.
Dental imaging is no different.
Many buyers immediately compare voxel size because smaller numbers often sound better.
In reality, image quality depends on much more than resolution alone.
Factors that influence diagnostic image quality include:
A properly maintained CBCT with excellent software may produce better clinical images than a newer system with more impressive specifications on paper.
Whenever possible, ask to review actual clinical scans—not just sample marketing images.
Field of view is one of the most important purchasing decisions you'll make.
A larger field of view captures more anatomy, but that doesn't automatically make it better.
Ideal for:
Benefits include:
Often the most versatile option for general dentistry.
Suitable for:
Typically preferred by:
A larger field of view provides greater anatomical context but isn't necessary for every patient or every procedure.
The best choice is the one that matches the services you perform most often.
This surprises many buyers.
The hardware captures the scan.
The software determines how efficiently your team uses it every day.
When comparing systems, evaluate:
Your team will interact with the software every day.
A user-friendly interface can save hours over the life of the system.
Every manufacturer introduces new features.
Some are incredibly valuable.
Others may rarely be used.
Instead of asking what's new, ask:
Many premium CBCT systems continue delivering exceptional performance well beyond their original release date.
Long-term reliability is often a better investment than the newest feature.
Every imaging system eventually requires maintenance.
The question isn't whether service will be needed.
It's whether help will be available when you need it.
Ask:
Excellent service often becomes the deciding factor in long-term ownership satisfaction.
The purchase price is only the beginning.
Consider the full ownership experience, including:
Sometimes a machine with a slightly higher purchase price offers significantly lower ownership costs over its lifetime.
Likewise, a certified pre-owned premium system may provide exceptional value because much of the initial depreciation has already occurred.
Many practices purchase equipment based solely on today's needs.
Instead, think ahead.
Ask yourself:
Buying with future growth in mind can help avoid another major equipment purchase sooner than expected.
Before making a final decision, compare each system using these questions:
✔ Does it meet my clinical needs?
✔ Is the field of view appropriate?
✔ Is the software intuitive?
✔ Can it integrate with my existing workflow?
✔ Is it reliable?
✔ Are parts and service readily available?
✔ Is training included?
✔ Does the warranty provide peace of mind?
✔ What is the total cost of ownership?
✔ Will this machine still support my practice five years from now?
If you can confidently answer "yes" to each question, you're probably evaluating the right system.
One of the biggest lessons we've learned after working with thousands of imaging systems is that newer doesn't automatically mean better.
Many established platforms from manufacturers such as Planmeca, Carestream, i-CAT, Vatech, and Sirona continue delivering outstanding diagnostic performance years after their original release.
For many practices, a certified pre-owned premium system offers the ideal combination of image quality, reliability, support, and value.
Comparing CBCT machines doesn't have to be overwhelming.
Instead of focusing on marketing claims or technical jargon, focus on the factors that will affect your practice every day:
When you compare systems through that lens, you'll make a more informed decision—and one that continues benefiting your practice long after installation.
At Renew Digital, that's how we evaluate every imaging system. And it's the same approach we encourage every dentist to take before making one of the most important technology investments in their practice.
Whether you're evaluating a brand-new machine or considering a certified pre-owned alternative, Renew Digital can help you compare your options objectively.
Our imaging specialists work with leading manufacturers and understand the strengths, workflows, and long-term ownership considerations of today's most popular CBCT systems.
Because the best CBCT isn't the one with the longest feature list—it's the one that's right for your practice.
