Choosing the right intraoral scanner for your dental clinic depends on your primary use case (restorative, orthodontic, or both), whether you need an open or closed file architecture, your total cost of ownership including software subscriptions, and compatibility with your lab and aligner system. Accuracy differences between current mid-range and premium scanners are smaller than most buyers expect for everyday crown and bridge work — scanning technique and team consistency matter more.

Two dentists with adjacent practices could legitimately choose different scanners and both be right. One focuses on restorative and works closely with a single lab. The other is building a clear aligner practice and needs maximum aligner system flexibility. Different workflows. Different answers.

The confusion in scanner purchasing comes from treating it as a brand comparison exercise when it is really a workflow planning exercise. Sort out the workflow first. The hardware decision becomes much clearer.

A 2025 systematic review with meta-analysis (PMC 11721843) of full-arch digital vs conventional impressions found that for single-unit and short-span fixed restorations, digital impression accuracy is clinically acceptable across current-generation scanners and comparable to conventional PVS. The performance gap between devices is modest for routine restorative work.

Full-arch accuracy is a different story. A 2023 network meta-analysis by Vitai et al. in the Journal of Dentistry found that different intraoral scanners should be selected according to arch type — the accuracy variation between devices becomes clinically significant as span length increases and in implant cases where passive fit is critical.

Practical implication: for everyday crown and bridge work, the difference between a $25,000 and $50,000 scanner in clinical outcome is smaller than the variation introduced by inconsistent scanning technique. Buy training alongside any scanner purchase.

Step 1: Define your primary use case

•       Restorative (crown, bridge, inlays): Priority is margin accuracy, deep prep capture, and lab file compatibility. Most current scanners perform acceptably for single-unit and short-span cases. Full-arch and implant cases require closer evaluation of specific scanner performance data.

•       Orthodontics / clear aligners: Confirm scanner compatibility with your chosen aligner system before purchasing. For clinical guidance on aligner case selection and digital workflow, see our clear aligner training guide.

•       Mixed restorative and orthodontic: Open-architecture scanners with strong software ecosystems generally serve mixed practices best, giving you flexibility across labs and aligner providers.

Step 2: Understand open vs. closed architecture

•       Closed systems (e.g. Dentsply Sirona): Integrate scanner, design software, and milling or production natively. Tight workflow, limited external flexibility. Some closed systems require unlocking fees or separate export licenses to send files to third-party labs or software.

•       Open systems (e.g. Eletra ,Medit, 3Shape, Planmeca, Shining 3D, Cameo): Export standard .STL, .OBJ, or .PLY files that any compatible lab, aligner provider, or CAD/CAM software can receive. You get full file ownership and third-party lab compatibility out of the box. More flexibility; requires greater software literacy and third-party CAD selection.

Pragmatic note: the open vs. closed line has softened in recent years. Several historically closed systems now offer file export — sometimes at a cost, sometimes free on request. Before you buy, get written confirmation of which file formats the scanner exports, whether export requires an additional license or fee, and whether your specific lab and aligner provider accept those files directly.

Step 2b: Should you run two scanners in your practice?

Many clinics now operate more than one intraoral scanner — particularly multi-operatory practices with more than one clinician. There are two clear reasons this has become common:

•       Backup and downtime risk management: A scanner failure mid-appointment with no alternative means rescheduled restorative and aligner cases. A second scanner — even an entry-level unit — keeps digital workflows running during repair, calibration, or software issues.

•       Parallel chair capacity: When two patients are in chairs at the same time and both need digital impressions, a single scanner creates a bottleneck. A second unit lets two clinicians or assistants scan simultaneously without idle chair time.

Some practices deliberately choose two different brands — for example, a premium scanner as the primary unit and a lower-cost open-architecture scanner as the backup or hygiene-operatory unit. This can balance capital outlay, give clinical staff exposure to more than one software, and preserve workflow continuity if one manufacturer has a service issue. The trade-off is managing two software ecosystems and two sets of training materials.

If you are considering a second scanner, model the decision on actual chair utilization and the cost of a half-day of lost digital impression capacity — not on the sticker price alone.

Step 3: Calculate the real total cost

Hardware prices range from approximately $10,000 to $50,000 USD for current-generation scanners. That is not the number that matters for a 5-year ownership calculation.

Before signing, get written confirmation on:

•       Annual software subscription fees: range from $0 to $5,000+/year depending on brand. Over 5 years, this frequently exceeds the hardware price gap between mid-range and premium models.

•       Warranty coverage and deductibles: A scanner that fails without adequate support is a patient care disruption.

•       Training and onboarding: Is structured team training included or billed separately?

•       Consumables: Scan tips, sleeve systems, and sterilization requirements vary significantly in ongoing cost.

Step 4: Do not buy based on spec sheets

Scanner accuracy, speed, and field-of-view claims are not standardized across manufacturers. Marketing specifications are measured under controlled conditions, not clinical ones.

The single most useful pre-purchase step: arrange a live demo in your practice on your own patients. Assess wand ergonomics in your hands, how your team interacts with the software, real-time scan visualization quality, and how the file format reaches your specific lab. This cannot be replicated in a showroom demo.

A scanner your team uses confidently and consistently generates its own return. A scanner that stalls during adoption because the workflow was not properly established does not.

Structured CE in digital dentistry — covering scanning strategy, open vs. closed system navigation, and how digital impressions integrate with restorative and orthodontic workflows — is the most reliable way to accelerate that adoption curve. CE and CPD credit availability varies by program; check the course page for credit details and the claim process before enrolling.

How do I choose the right intraoral scanner for my dental practice?

Start by defining your primary use case: restorative, orthodontic, or both. For restorative, evaluate full-arch accuracy if you plan implant or long-span bridge cases. For orthodontics, confirm scanner compatibility with your aligner system before purchasing hardware. Then assess open vs. closed architecture, total cost of ownership including annual software fees, and arrange a live demo in your own practice. Spec sheets alone are insufficient for this decision.

What is the difference between open and closed intraoral scanner systems?

Open systems (e.g. Medit, 3Shape, Planmeca, Shining 3D, Cameo, Eletra) export standard file formats (.STL, .OBJ, .PLY) that any compatible lab or aligner provider can receive, giving you workflow flexibility. Closed systems (e.g. Dentsply Sirona) use proprietary file formats optimized for that manufacturer's ecosystem — tighter integration within the system, more constrained flexibility outside it. Some closed systems charge fees to export or unlock files for third-party use.

Should a dental practice own two intraoral scanners?

For single-operatory practices with one clinician, one scanner is usually sufficient. Multi-operatory practices with more than one clinician increasingly run two scanners for two reasons: backup coverage during service or software issues, and parallel capacity when two patients need digital impressions at the same time. Some clinics intentionally choose two different brands to balance cost, spread vendor risk, and give the team exposure to more than one software. Model the decision on chair utilization and the cost of lost digital impression capacity, not on sticker price alone.

Are more expensive intraoral scanners significantly more accurate?

Not necessarily for everyday restorative cases. A 2025 systematic review (PMC) found that for single-unit and short-span fixed restorations, current mid-range and premium scanners both perform within clinically acceptable accuracy ranges. Accuracy differences become more meaningful for full-arch cases, implant cases, and long-span prosthetics. For most GPs, scanning technique and team consistency contribute more to clinical outcome than hardware tier.

What are the ongoing costs of owning an intraoral scanner?

Beyond the hardware purchase ($10,000–$50,000 USD for most current-generation models), annual software subscription fees range from $0 to $5,000+ per year depending on brand. There are also consumable costs (scan tips, disposable sleeves), potential warranty deductibles, and training costs if not included in the purchase. Always request a full cost-of-ownership breakdown over 3–5 years before signing.

Do I need an intraoral scanner to offer clear aligners?

No — most aligner systems still accept physical PVS impressions. However, digital scanning streamlines case submission and reduces retake rates. For any practice building meaningful aligner volume, a scanner is a practical infrastructure investment.
