What clinical research shows about iTero Lumina™ scanner and the Invisalign® Practice App compared to DSLR camera workflows.

Digital dentistry is often described as faster and more efficient — but for many clinicians, the real questions are practical ones:

  • Can a simpler capture workflow replace the gold standard for dental photography?
  • Can intraoral scanning reduce chair time without compromising image quality?
  • Is it reliable enough for everyday orthodontic treatment planning?


To answer these questions, Align Technology conducted a clinical study comparing a fully digital capture workflow — iTero Lumina™ intraoral scanner combined with the Invisalign® Practice App (IPA) — against the current standard of care in orthodontic photography using a DSLR camera.


This article explains why the research was done, how it was conducted, and what the results mean for daily clinical practice.
 

 Why look for an alternative to DSLR clinical photography?

DSLR photography has long been considered the gold standard for clinical documentation and orthodontic records. When executed well, it produces high‑quality images — but it often comes with trade‑offs:

  • Complex camera setup and accessories
  • Dependence on trained staff and repeatable technique
  • Multiple retakes due to lighting, angulation, or focus
  • Longer chair time, especially in busy practices

Streamlining the capture process is valuable but only if clinical image quality is maintained.


That’s why this clinical study is focused on a critical question clinicians routinely ask:
Can a digital workflow deliver image quality comparable to DSLR photography — while reducing steps and chair time for orthodontic treatment record taking?
 

How the clinical study was designed

The study evaluated extraoral and intraoral clinical images captured using:

  • Invisalign® Practice App (IPA) for extraoral photography
  • iTero Lumina™ dental scanner for intraoral imaging derived from digital 3D models
  • DSLR photography as the standard‑of‑care comparator
     

A total of 65 subjects were included. All images were evaluated using American Board of Orthodontics (ABO) criteria, providing an objective and clinically relevant framework for assessment.


Image quality was assessed by three independent reviewers from the orthodontic department at New York University, using ABO-based criteria widely adopted in dental schools and orthodontic residency programs as the benchmark for clinical photography.

What was assessed

  • Overall image quality
  • Dentition and occlusion visualization
  • Soft tissue representation
  • General clinical conditions relevant to orthodontic treatment planning


This ensured the comparison focused on clinical usability, not just technical image resolution.

Can an intraoral scanner and smartphone app-based workflow help streamline clinical records capture compared with a conventional DSLR workflow?

While the study focused on image quality, the workflow differences between the two approaches are worth noting.

Orthodontic record-taking workflow comparison

Both workflows produce the same clinical records. With the iTero Lumina™ dental scanner + Invisalign® Practice App (IPA), the intraoral scan already generates intraoral images, reducing the need for a separate DSLR photo session.

Key takeaway: Both workflows require the same orthodontic records (X-rays, extraoral photos, intraoral images, digital models). The difference is that the iTero Lumina™ intraoral scan produces both the digital models and the intraoral color images in a single step, reducing the need for a separate DSLR intraoral photography session with retractors, mirrors, and assistant.

  • With iTero Lumina™ intraoral scanner and the Invisalign® Practice App, clinicians can:
  • Capture extraoral and intraoral records 
  • Reduce dependency on assistants for photography
  • Avoid repeated positioning, lighting adjustments, and retakes
  • Move directly from capture to visualization and treatment planning

In contrast, DSLR workflows typically require:

  • Dedicated camera equipment and accessories
  • Manual setup and adjustments
  • Multiple steps before images are ready for use

These workflow differences are reflected in how doctors experience photo capture in daily practice. Align Technology research data shows that 98% of surveyed doctors agree that photo capture with the Invisalign® Practice App requires fewer steps than using a DSLR camera¹, and that 98% agree it is faster than DSLR photography, on average by approximately 74%². Among General Practitioners specifically, the reported time savings increase to around 76% compared to DSLR workflows³.


Fewer steps and guided capture translate directly into shorter chair time, particularly in high‑volume practices where efficiency matters most.
 

Thinking about the financial impact?
Shorter chair time and more efficient record capture don’t just improve workflows — they can directly affect practice economics. Use the iTero ROI calculator to estimate how digital scanning could impact productivity and return on investment in your own practice.
 

How does the Invisalign® Practice App perform for extraoral clinical photography?

Invisalign® Practice App delivers superior extraoral photography for orthodontic treatment planning, outperforming traditional DSLR cameras based on American Board of Orthodontics scoring criteria⁴.

 

In the clinical study:

  • The overall mean score for extraoral photos was 52.89 for IPA, compared to 51.14 for DSLR⁴
  • Images captured with IPA met or exceeded ABO‑defined clinical quality standards⁴

Beyond clinical scoring, doctor preference data reinforces these findings:

  • 84% of surveyed General Practitioners and Orthodontists prefer the quality of photos captured with the Invisalign® Practice App over DSLR cameras when submitting Invisalign cases⁵
  • This includes 89% of GPs⁶ and 75% of orthodontists⁷ surveyed


For clinicians, this means:

  • High-quality extraoral photos without the complexity of a full DSLR setup
  • Built-in guidance that helps standardize every capture regardless of who's behind the camera
  • Photos that flow directly into the patient record, no manual file transfer needed

How reliable is iTero Lumina™ dental scanner for intraoral imaging compared to DSLR photography?

iTero Lumina™ scanner provides reliable intraoral imaging for orthodontic treatment planning, achieving comparable outcomes to DSLR photography overall, with superior performance in capturing dentition and occlusion, as evaluated based on American Board of Orthodontics criteria⁸.


Study findings showed:

  • An overall weighted average intraoral score of 78.41 for iTero Lumina™ scans, compared to 77.27 for DSLR⁸
  • Palate image quality comparable to DSLR intraoral photos⁸
  • DSLR intraoral photos are currently outperforming iTero Lumina™ scans for mucosa and gingiva⁸. However, that might change in near future as iTeroTM software versions continue to improve, including higher-quality models of the surface representation for both hard and soft tissue.

These results highlight an important distinction:

What this means for everyday clinical practice

For clinicians evaluating digital dentistry tools, this study helps clarify what “better” actually means:

  • Better efficiency: fewer steps and guided capture¹
  • Better chair time management: faster record acquisition with fewer retakes² ³
  • Comparable clinical quality: validated using recognized orthodontic evaluation criteria⁴ ⁸


Rather than choosing between speed or image quality, workflows like iTero Lumina™ scanner + Invisalign® Practice App are designed to deliver both.

Frequently Asked Questions

Can an app-and-scanner workflow match DSLR image quality while saving time?


Clinical research shows that digital dentistry workflows can be both faster and clinically reliable, depending on the tools used. In a clinical study comparing a fully digital workflow (iTero Lumina™ scanner and the Invisalign® Practice App) to DSLR photography, digital capture achieved comparable or higher image quality scores while reducing setup steps and retakes. Fewer steps and guided capture support shorter chair time without compromising clinical standards.

 

Is a scanner-and-app workflow better than a DSLR camera workflow for clinical photography?


“Better” depends on what you’re evaluating. Traditional DSLR photography remains strong for certain image types, such as mucosa and gingiva. However, digital workflows are designed to improve efficiency, consistency, and repeatability in daily practice. When evaluated using American Board of Orthodontics criteria, digital tools like iTero Lumina™ and the Invisalign® Practice App delivered comparable overall clinical outcomes with a simpler workflow.
