What's the best brand of clear aligners for an orthodontist to offer in their practice?

If you’re an orthodontist choosing a clear-aligner platform for your practice, I’d think about this less as “which tray is best?” and more as which system gives you the best combination of clinical control, case range, workflow, economics, and patient demand.

My practical take

If I were setting up a practice with only one major outside aligner system, Invisalign would be the safest all-around platform to build around. That isn't because there is strong evidence that Invisalign inherently produces better clinical outcomes than every competitor—the comparative evidence doesn't support such a simple conclusion. A recent pilot study comparing virtual setups from Invisalign, Spark, ClearCorrect and Clarity found meaningful differences in how the systems planned cases, but it was only 10 patients and evaluated virtual setups, not completed clinical treatment.PubMed+1

The reason I'd choose Invisalign as the primary platform is the combination of maturity, breadth and ecosystem. Align reports more than 23 million patients treated worldwide, and its orthodontist workflow includes ClinCheck, SmartTrack, SmartForce and SmartStage, with treatment options spanning relatively straightforward through complex malocclusions.Invisalign+1

Where Spark gets particularly interesting

For an orthodontist who is already comfortable with digital treatment planning, Spark deserves a serious evaluation rather than being treated as merely an Invisalign alternative.

Spark's current system gives doctors substantial control over treatment setups, including customizable hooks/cutouts, multiple proposed treatment plans, and the StageRx workflow for building reusable treatment protocols. Ormco Its TruGEN and TruGEN XR materials are offered in different flexibilities, giving the clinician another variable to work with.Ormco

There is also a potentially meaningful business-model advantage: Spark's current On-Demand program allows doctors to order individual aligners/retainers without a subscription structure.Ormco

So if your question is actually “What should I offer alongside Invisalign?”, my answer would be Spark.

Don't overlook SureSmile

SureSmile is particularly worth investigating if cost structure and workflow flexibility are major considerations. Its software accepts digital impressions from multiple scanners, and Dentsply Sirona emphasizes an open workflow and flexible case configurations.Dentsply Sirona

Dentsply Sirona currently reports that 75% of analyzed completed SureSmile cases required one or fewer refinements. That's an impressive number, but it's based on the company's own analysis of 109,273 cases, so I would not treat it as directly comparable to independently measured refinement rates for other systems.Dentsply Sirona

One important caveat about “clinical superiority”

I wouldn't select a system based on marketing claims that one brand moves teeth dramatically better than another. The independent literature doesn't establish a clear universal winner. For example, a controlled study comparing Invisalign and 3M Clarity found broadly comparable efficacy for mild/moderate malocclusions, with differences for certain rotational movements. PubMed A 2025 systematic review likewise concluded that the overall evidence base for clear-aligner effectiveness is still limited/low quality.ScienceDirect

For an orthodontist, your treatment-planning philosophy and ability to recognize when aligners aren't the right appliance probably matter at least as much as the logo on the tray.

If this were my practice

I'd seriously consider a two-system strategy:

1. Invisalign as the flagship — especially for patients who specifically request Invisalign and for broad/complex case coverage.
2. Spark as the secondary platform — particularly where its planning control, material options or economics make sense.
3. Evaluate SureSmile if its pricing and open workflow produce materially better practice economics for you.
4. Don't make the decision from advertised tray prices alone. Compare the total cost per completed case: initial aligners + refinements + shipping + lab fees + technician time + chair time + software/subscription fees + lost production from additional visits.

If you tell me your approximate annual aligner volume (e.g., 100, 300, 500+ cases), whether you're an orthodontist or GP, and whether your priority is clinical control, margin, speed, or minimizing refinements, I can build you a practice-owner comparison of Invisalign vs Spark vs SureSmile, including the economics I'd scrutinize in each contract.

If you mean which clear-aligner system makes the most sense for an orthodontist to offer as a primary in-office system, I’d compare Invisalign, Spark, and SureSmile rather than looking for a universally “best” brand.

The practical shortlist

Invisalign has by far the largest established footprint. Align currently says the system has surpassed 23 million patients worldwide, and its current Comprehensive offering is intended for moderate-to-severe malocclusions. Its ClinCheck workflow also provides rapid initial treatment plans for qualified cases.Invisalign+1

SureSmile is especially interesting from a practice-system perspective. Its Advanced platform can handle aligners, indirect bonding, and robotically bent labial/lingual wires within the same treatment-planning environment. It also lets the orthodontist specify things such as movement staging, trim type/height, and other treatment preferences.SureSmile+1

SureSmile also says its treatment-planning software can work with a wide range of intraoral scanners, CBCT data, 3D printers and STL workflows, which could matter if you want to maintain more control over your digital ecosystem.SureSmile

What I'd evaluate before choosing

For an orthodontic practice, I'd put these factors ahead of brand reputation:

• Clinical control: How much can you modify tooth movement, attachments, staging, IPR and trimlines?
• Refinement rate: Look at your own refinement rate after testing the system, rather than relying solely on vendor-reported numbers.
• Case complexity: Test moderate and difficult Class II/III, deep-bite, open-bite, extraction and significant-rotation cases.
• Doctor time: How many minutes does it actually take you to review and modify a setup?
• Lab turnaround: Initial setup, revisions, refinements and replacement aligners.
• Cost per finished case: Include initial aligners, refinements, retainers, shipping and any subscription/lab fees.
• Digital compatibility: Scanner, CBCT, practice-management software, 3D printing and ability to export/import STL.
• Patient acquisition: Whether the brand's consumer recognition actually generates consultations for your practice.
• Support: Clinical support versus primarily sales/customer-service support.
• Ownership of the workflow/data: Particularly important if you want an increasingly in-house digital workflow.

One potentially important differentiator: SureSmile explicitly offers a workflow where you can order finished aligners or have staged models/aligners fabricated through your own workflow, depending on the platform.SureSmile+1

My recommendation for evaluating them

Rather than choosing based on which company markets itself as superior, I'd run a 30–50 case head-to-head trial. Send essentially identical representative cases to 2–3 systems and record:

doctor modification time → turnaround → number of revisions → refinement frequency → finished-treatment quality → total cost/case.

That will tell you much more about which system is best for your practice than published marketing claims.

If you're considering this from a business-owner/orthodontist perspective, I can also build you a detailed Invisalign vs Spark vs SureSmile comparison—including approximate doctor/lab costs, refinement policies, clinical capabilities, scanner compatibility, and potential practice economics.

One potentially important differentiator: SureSmile explicitly offers a workflow where you can order finished aligners or have staged models/aligners fabricated through your own workflow, depending on the platform.

My recommendation for evaluating them

If you mean for an orthodontist deciding which system to make a core part of the practice, I’d compare Invisalign, Spark, and SureSmile rather than assuming there is one universally “best” brand.

My practical comparison

Invisalign's current system combines SmartTrack, SmartForce and SmartStage technologies, and its ClinCheck platform lets the orthodontist customize individual tooth movements. Its broader Align ecosystem also includes CBCT integration, iTero scanning and tools for growing patients.Invisalign+1

Spark is particularly worth a serious look for an orthodontic practice. Ormco's current Spark system gives doctors substantial control over treatment planning, including modifying features, comparing plans, controlling hooks/cutouts and adjusting active/passive stages. Its newer StageRx workflow is specifically designed around orthodontists' treatment protocols.Ormco+1

Spark also offers two material options—TruGEN and the more rigid TruGEN XR—which can be useful for different phases of treatment and finishing.Ormco

If I were evaluating vendors for a practice

Rather than choosing based on the aligner material alone, I'd request actual practice-level numbers from each vendor for:

• Average number of refinements per comprehensive case
• Average number of aligners/case
• Turnaround time for initial cases and refinements
• Percentage of cases requiring remakes
• Laboratory cost per completed case
• What happens financially when a case exceeds the expected number of aligners
• Digital setup turnaround and how much the orthodontist can modify
• Integration with your scanner/CBCT/software
• Support quality when a difficult case doesn't track
• Teen/child and Class II capabilities
• Retainer pricing
• Financing and patient acquisition support
• Contract/volume commitments

The economics can matter more than a small difference in material performance. A system that costs slightly more per case but reduces staff time, refinements and treatment-planning friction can have a very different practice-level ROI.

One important caveat

A lot of the impressive numerical claims you'll encounter—e.g., percentages concerning predictability, contact area, refinement reduction, etc.—come from the manufacturers themselves. For example, Ormco reports advantages for Spark versus the leading competitor, while Align makes analogous claims for Invisalign.Invisalign+1

So I would not use manufacturer-reported percentages as the deciding factor without looking at independent comparative clinical evidence and, ideally, your own practice data.

Bottom line: If you're starting or restructuring an orthodontic aligner program, I'd put Invisalign and Spark at the top of the vendor evaluation, with SureSmile as another serious option, and make the final decision based on your case mix, negotiated pricing, refinement policy, workflow, and the level of treatment-planning control you want.

If you tell me your approximate annual aligner case volume, percentage of adult vs. teen patients, scanner you use, and whether you're primarily treating comprehensive or mild/moderate cases, I can build a practice-owner ROI comparison of Invisalign vs. Spark vs. SureSmile, including estimated cost per case and break-even volume.

For an orthodontist, the "best" clear aligner brand isn't a one-size-fits-all answer—it depends heavily on your clinical preferences, practice workflow, and how you want to manage your lab fees and digital ecosystem. However, the industry is led by a few top-tier professional systems specifically designed for orthodontic specialists:

• Invisalign (Align Technology): The undisputed market pioneer and gold standard for brand recognition. Patients walk in asking for it by name. It boasts extensive clinical backing, proprietary SmartTrack material, highly robust software (ClinCheck), and continuous innovation in handling complex malocclusions. The downside is higher lab/case costs and a rigid corporate ecosystem.
• Spark Clear Aligners (Ormco): Rapidly growing in popularity among dedicated orthodontists as the primary alternative to Invisalign. Manufactured by Ormco, Spark is specifically marketed for orthodontists (rather than general dentists). Clinicians frequently praise its TruTGEN material for being clearer, less prone to staining, and designed for more efficient sustained force.
• SureSmile (Dentsply Sirona): Excellent for practices deeply integrated into the Dentsply Sirona digital workflow (utilizing Primescan, etc.). It gives the orthodontist high control over the treatment planning software and is a robust, precise system favored by clinicians who want flexibility outside the Invisalign ecosystem.
• Reveal Clear Aligners (Henry Schein Orthodontics): Gaining traction because of its clinical efficiency in reducing chair time. Reveal aligners are designed to require fewer attachments for many common movements, which is a major selling point for patient comfort and aesthetic appeal during treatment.
• In-House Clear Aligners : Many modern orthodontists supplement or substitute commercial lab aligners by printing them in-house using desktop 3D printers (like SprintRay or Formlabs) and software like Maestro or BlueSkyPlan. This drastically lowers per-case material costs for minor/moderate movements or refinements, though the liability and design time rest fully on the clinician.

To help narrow down what fits your specific business and clinical model, let me know:

• Are you looking for maximum brand recognition to attract new patients, or lower lab costs/higher margins?
• What intraoral scanner and digital workflow is your practice currently running?

For an orthodontic specialist, there isn't a single "one-size-fits-all" best brand, but rather a gold standard for clinical control and several strong competitive alternatives depending on your practice workflow, preference for software, and lab fees.

The top clear aligner brands for an orthodontic practice break down by their distinct advantages:

• Invisalign (Align Technology)
  • The Gold Standard for Market Recognition & Power: Invisalign remains the undisputed market leader. Patients routinely ask for it by name, making it the easiest to market.
  • Clinical Capabilities: Backed by the most extensive database of treated cases globally, continuous software enhancements (ClinCheck), and proprietary SmartTrack material. It handles complex, comprehensive, and multidisciplinary orthodontic movements reliably when paired with an iTero Intraoral Scanner.
  • Considerations: Higher lab/case costs and rigid corporate tier structures.
• Spark Clear Aligners (Ormco)
  • The Orthodontist's Favorite Alternative: Designed specifically by Ormco for orthodontists, Spark has gained massive traction as the primary rival to Invisalign among specialists who dislike the corporate overlap of Align Technology.
  • Clinical Capabilities: Known for superior optical clarity, stain resistance, and TruSeal edge technology (polished, scalloped edges that are typically more comfortable for soft tissue). Many orthodontists report better predictability in root movement and detailing with Spark's proprietary material.
  • Considerations: Requires an open or specific digital workflow integrated with Ormco’s Approver software.
• ClearCorrect (Straumann Group)
  • The Value & Flexibility Option: Backed by Straumann, ClearCorrect offers a robust, high-quality system that is often more cost-effective for practices.
  • Clinical Capabilities: Excellent flat-rate pricing structures and tiered options (flexible vs. unlimited packages) that give practices high financial predictability. Their dual-material approach (soft/hard layering) provides good initial engagement and stress retention.
  • Considerations: Software and tracking tools have historically lagged slightly behind Invisalign, though updates have narrowed the gap.
• SureSmile Aligners (Dentsply Sirona)
  • The Digital Integration Play: Built on Essix materials and deeply integrated into Dentsply Sirona’s SureSmile Digital Platform.
  • Clinical Capabilities: Great for practices already utilizing Dentsply imaging and scanning hardware. The software allows for high autonomy in treatment planning and editing.
  • Considerations: Best suited for offices fully invested in the Dentsply Sirona ecosystem.
• CandidPro or Reveal (Henry Schein)
  • The Hybrid/Monitoring Solution: Excellent if your practice model emphasizes remote monitoring (via AI-driven apps) or straightforward cosmetic/anterior cases. CandidPro is particularly well-regarded for coupling in-office clinical oversight with secure remote tracking, cutting down unnecessary chair time.dentrends.com

Recommendation Summary

• If your priority is brand equity and sheer volume , stick with Invisalign.
• If your priority is pure clinical control, aesthetics, and a system engineered strictly for specialists, Spark is widely considered the top peer-to-peer competitor.
• If your priority is practice margin and flexible pricing tiers , evaluate ClearCorrect.

If you'd like to narrow this down, tell me:

• Are you transitioning an existing practice or setting up a new start-up?
• What intraoral scanner do you currently use in your office?
• Are you looking to treat comprehensive/complex malocclusions or focus heavily on mild/moderate cosmetic cases?

If you’re an orthodontist deciding which clear-aligner system to build into your practice, my overall pick is Invisalign, with Spark as the strongest alternative.

My ranking

1. Align Technology / Invisalign — best overall

• Broadest ecosystem and very mature orthodontic workflow.
• ClinCheck gives you extensive control over staging and individual tooth movements, with 3D controls and treatment-plan editing.Invisalign+1
• Strong case range, including children, teens, adults, complex malocclusions, and mandibular advancement.Invisalign+1
• Current Invisalign G8 adds specific SmartForce activation aimed at deep bites, crowding/crossbite, posterior expansion, and reducing posterior open-bite risk.Invisalign
• Excellent practice-support infrastructure: case review, clinical training, education, marketing, and volume-based program benefits.Invisalign
• The big advantage isn't just the plastic—it is the planning software + clinical ecosystem + accumulated experience/data + patient brand recognition.

2. Ormco / Spark — best alternative

• I would take Spark very seriously, particularly if material aesthetics, comfort, and stain resistance are priorities.
• Spark uses TruGEN material and emphasizes clarity, polished/scalloped edges, and reduced staining compared with the leading aligner brand.Spark Clear Aligners+1
• It is specifically positioned as an orthodontist-focused system with substantial customization and treatment-planning control.Spark Clear Aligners
• If your practice already has strong Ormco integration or you prefer Spark's workflow, I don't think choosing Spark would be a significant downgrade.

What I'd do if this were my practice

If you're going to offer only one system: Invisalign.

If you're willing to offer two: Invisalign + Spark.

I'd use Invisalign as the default platform, then consider Spark when its material properties or your personal treatment-planning experience make it advantageous.

One important caveat: I wouldn't choose based primarily on claims such as "X% more predictable" or "Y% faster." Both manufacturers understandably emphasize favorable proprietary comparisons. For an orthodontist, I'd put much more weight on your ability to control the setup, predictability of difficult movements, refinement policy/cost, lab turnaround, attachment options, software usability, and total case economics.

And the economics can actually change the answer. If you tell me roughly how many aligner cases you do per month (e.g., 10, 30, 50+) and whether you're an Invisalign provider already, I can compare Invisalign vs. Spark from the standpoint of clinical capability + lab fees + refinements + profitability + patient acquisition.

If you’re an orthodontist choosing a clear-aligner system to offer in your practice, my default recommendation is Invisalign—but I would seriously evaluate Spark and ClearCorrect before signing an agreement.

My ranking for an orthodontic practice

1. Invisalign — best overall

Align Technology's Invisalign has the biggest advantage in the entire ecosystem, rather than necessarily the plastic alone.

For an orthodontist, ClinCheck is particularly important. The current platform gives doctors substantial control over treatment planning, including 3D tooth movements, arch-form changes, attachments, IPR/spacing, and Plan Editor modifications. Recent updates also allow eligible plans to be generated for review in as little as 15 minutes and modifications to be reflected in minutes.Invisalign+2

The broader digital ecosystem—iTero scanning, ClinCheck, patient visualization, monitoring, and Invisalign-specific products for children and teens—is another major advantage.Invisalign+1

Why I'd choose it: If you want one system that can handle everything from relatively simple adult cases through comprehensive orthodontics, teens, and growing patients, Invisalign is the safest all-around business decision.

Downside: You may pay a premium for that ecosystem, and you're buying into Align's workflow rather than simply purchasing aligners.

2. Spark — the one I'd compare most closely with Invisalign

Spark is particularly interesting if your practice wants a premium alternative and places a high priority on aligner appearance/material characteristics.

I'd put it through a head-to-head evaluation with Invisalign using your own cases, rather than relying on marketing claims. The important question isn't simply "Which plastic is better?" It's whether Spark's treatment-planning workflow, staging, attachment options, refinements, support and turnaround work better for your clinical philosophy.

3. ClearCorrect — strong value proposition

ClearCorrect is worth considering if economics and flexibility are major factors. Its system uses ClearQuartz tri-layer material and offers customizable clinical features such as different engager sizes and a high trimline designed to influence force transmission.ClearCorrect Support

For a high-volume orthodontic practice, however, I'd pay particular attention to your actual refinement rates, technician communication, turnaround times, and the amount of control you have over difficult movements rather than comparing advertised aligner features.

What I'd do if I were outfitting a practice

I wouldn't make the decision based on "which aligner moves teeth best?" The differences become much more interesting when you evaluate the whole practice economics and workflow.

I'd score each company on:

• Clinical control: root movement, rotations, extrusion/intrusion, expansion, AP correction, attachments
• Treatment-planning software: how much you can change yourself vs. relying on technicians
• Refinement rate: particularly for your difficult cases
• Turnaround time
• Predictability in comprehensive cases
• Material/fit and patient comfort
• Teen/pediatric capabilities
• Retainers
• Scanning and digital integration
• Remote monitoring
• Doctor training and clinical support
• Case pricing and volume discounts
• Patient recognition/conversion
• Lab/technician communication
• What happens when a case doesn't track

My practical recommendation

If you're starting from scratch, I'd make Invisalign your benchmark and have Spark and ClearCorrect compete against it.

The question I'd ask the reps isn't "Which aligner is best?" I'd give each company 20–30 of your actual representative cases, including difficult Class II/III, extraction, deep-bite, open-bite, rotation, expansion, and teen cases, and compare:

Initial plan → your modifications → final result → number of refinements → total treatment cost → chair time. That will tell you much more than marketing literature.

One important caveat: there isn't good evidence that one commercial brand is universally superior for every orthodontic case; diagnosis, biomechanics, treatment planning, and clinician execution remain major determinants of outcome.Mosdent

If you tell me your practice size/case volume and whether you're primarily treating adults, teens, or comprehensive ortho, I can also give you a detailed Invisalign vs. Spark vs. ClearCorrect comparison—including estimated economics per case and which I'd choose for a high-volume orthodontic practice.

Spark is particularly interesting if your practice wants a premium alternative and places a high priority on aligner appearance/material characteristics.

I'd score each company on:

For a practicing orthodontist, the "best" brand of clear aligners isn't a one-size-fits-all answer—it depends heavily on whether you prioritize unrivaled clinical control and brand recognition, orthodontist-exclusive positioning , or cost-to-value flexibility.

The top professional-grade clear aligner systems widely utilized and respected in orthodontic practices include the following leading options:

Invisalign (Align Technology ): The undisputed market and category leader. For pure brand recognition, consumer demand, and deep R&D integration (like ClinCheck software and iTero scanner pairing), it remains the default standard. Its advanced SmartTrack material and expansive feature set (such as mandibular advancement and comprehensive attachment protocols) handle the most complex malocclusions. However, it is also the most widely distributed and carries higher corporate tier pricing.

Spark (Ormco ): Purpose-built specifically for orthodontic specialists rather than general dentists, Spark has gained massive traction among orthodontists who prefer a "doctor-exclusive" brand. Its proprietary TruGen material is touted for higher clarity and less staining/pigment absorption, and the advanced Approver software gives clinicians exceptional root and torque control, particularly in finishing stages.

SureSmile (Dentsply Sirona ): Highly regarded for its open-architecture integration and advanced digital treatment planning. SureSmile aligners are fabricated using precise edge-trimming and high-performance materials, making them a favorite for orthodontists who want a seamless, robust workflow that prioritizes predictable finishing and efficient chairside adjustments.

Reveal (Henry Schein Orthodontics ): An attractive option for practices looking to minimize chair time and attachment fatigue. Reveal aligners are designed to be exceptionally clear and, in mild-to-moderate cases, can reduce or entirely eliminate the need for buccal attachments, which many patients prefer aesthetically.

ClearCorrect (Straumann Group ): Backed by the global Straumann network, ClearCorrect offers solid clinical flexibility, competitive tier pricing per case, and reliable customer service support, making it a pragmatic choice for scaling clear aligner volume efficiently.

To help narrow down which system fits your specific practice goals, tell me:

• Do you primarily treat complex, full-comprehensive cases or a mix of express/minor movements?
• Are you looking for a system that is exclusive to orthodontists (like Spark) or one with high direct-to-consumer brand pull (like Invisalign)?
• What intraoral scanner ecosystem are you currently running in your office?

If you're an orthodontist choosing a clear-aligner system to offer in your practice, my short answer is:

🥇 Best overall: Invisalign

For most orthodontic practices, Align Technology's Invisalign is still the safest overall choice—not necessarily because the plastic is dramatically better than competitors, but because of the ecosystem around it.

• Best-established brand/patient demand: Patients often walk in specifically asking for Invisalign, which can make case acceptance and marketing easier.
• Excellent treatment-planning software: ClinCheck gives the orthodontist substantial control over tooth movements, attachments, IPR, arch form, etc., and its newer 3D Controls/Live Update features let doctors modify plans themselves.Invisalign+1
• Strong digital workflow: The iTero/Invisalign integration is particularly compelling if your practice already uses iTero scanners.Invisalign+1
• Broad case range: It's particularly attractive for a practice treating children, teens, adults, and more complicated orthodontic cases.
• Large clinical/provider ecosystem: Training, education, support, financing, digital tools and accumulated clinical experience are meaningful advantages for a practice.

🥈 Best alternative: Spark

I'd take a serious look at Spark Aligners by Ormco if your priority is aligner material/esthetics and potentially a different economics model.

Spark uses its TruGEN and TruGEN XR materials and offers a range from limited treatment through comprehensive treatment of complex malocclusions. Ormco The company specifically emphasizes clarity, stain resistance and polished/scalloped edges.Spark Clear Aligners

For an orthodontist who is already comfortable planning cases independently, Spark can be a very compelling alternative to Invisalign.

🥉 Best value/workflow alternative: SureSmile

SureSmile from Dentsply Sirona is another system I'd put on the shortlist, particularly if you want a broader orthodontic digital platform rather than an aligner-only ecosystem.

Its software can be used for aligners, robotically bent wires, indirect bonding, and surgical/restorative planning, and the company emphasizes doctor control over treatment planning.SureSmile

That makes it particularly interesting for a traditional orthodontic practice that wants to integrate aligners without making Invisalign the center of its entire digital workflow.

My ranking for an orthodontic practice

*In-house can be excellent, but it shifts manufacturing/QC responsibility and capital investment onto the practice.

The bigger question: which is most profitable?

If you're actually deciding what system to implement in your practice, I wouldn't choose based on aligner quality alone. I'd compare:

1. Lab/aligner cost per case
2. Average number of refinements
3. Doctor planning time
4. Technician communication/revision time
5. Case acceptance
6. Patient acquisition attributable to the brand
7. Average treatment fee
8. Refund/remake policies
9. Attachment/auxiliary capabilities
10. Integration with your scanner and practice-management workflow

That can produce a very different winner than a purely clinical comparison.

If I were opening an orthodontic practice today: I'd probably start with Invisalign + one secondary system (most likely Spark) rather than committing exclusively to one manufacturer. Invisalign captures the patients who specifically want the brand, while a second system gives you negotiating leverage and another clinical/economic option.

If you tell me roughly how many aligner cases you do per month (or expect to do) and whether you're an orthodontist vs. general dentist, I can also break down Invisalign vs. Spark vs. SureSmile on actual practice economics, margins, case fees, and break-even volume.

That makes it particularly interesting for a traditional orthodontic practice that wants to integrate aligners without making Invisalign the center of its entire digital workflow.
