How to Add Digital Full Arch Implant Restorative Treatments to Your Dentistry

Across the globe, the need for predictable, long term restorative solutions is surging. A 2021 study Burden of severe periodontitis and edentulism in 2021, with projections up to 2050: The Global Burden of Disease 2021 study - Gustavo G Nascimento, Silas Alves-Costa, Mario Romandini reported that 353 million people were already living with edentulism, and more than one billion were suffering from severe periodontitis.

Projections indicate these numbers will climb to 660 million edentulous patients and 1.5 billion with severe periodontitis by 2050 - nearly one fifth of them in China alone.

For many of these patients, the full arch implant-based treatment concept has become one of the most reliable paths to rehabilitation. Introduced in the 1990s by Dr. Paulo Malo with support from Nobel Biocare, a full arch implant-based restoration was once considered a highly specialized procedure.

Today, however, new digital innovations from companies like Straumann, TruAbutment and 3Shape are helping bring the treatment into the mainstream.

But adoption hasn’t been without challenges.

Learn the TRIOS ioConnect workflow

Dr. Paulics and 3Shape have created a free and easy email course to help you learn the TruAbutment ioConnect workflow.

The course, over three emails, includes videos demonstrating the workflow steps.

WHY FULL ARCH DIGITAL SCANNING IS THE BARRIER IN THE DIGITAL WORKFLOW

While intraoral scanners have long produced excellent results for single implants, full arch implant impressions with scan bodies have proved challenging.

Capturing four or more implant positions across an arch introduces accuracy issues, including:

  • Reflections and glare from metal scan bodies
  • Interference from soft tissue and saliva
  • Limited access around scan bodies
  • Complex angles and steep undercuts
  • Accumulated stitching errors over long distances

Research shows that while the first scan body is typically captured at around 27 micrometers of accuracy, which is comparable to photogrammetry and conventional impressions, the accuracy can fall to an unacceptable 324 micrometers by the time we scan the opposite side of the arch.

A handful of highly experienced digital scanning experts manage to compensate for this. But for most clinicians, reliability simply hasn’t been there - until now.

The breakthrough: scan flag systems that change the game

To overcome the traditional limitations of full arch scanning, several implant companies introduced scan flag solutions designed to add geometry, stabilize reference points, and dramatically improve scan accuracy.

TruAbutment ioConnect

Using elongated, horizontally oriented scan flags

By creating a stable, reproducible reference framework in the mouth, these systems allow scanners like our 3Shape TRIOS to capture full arch implant positions with far higher confidence and consistency.

3Shape has worked with both Straumann and TruAbutment to deliver fully integrated TRIOS workflows using each company’s proprietary scan flags. Both the TRIOS TruAbutment ioConnect and Straumann EXACT integrated workflows are available.

A LOOK INSIDE THE TRIOS TRUABUTMENT IOCONNECT FULL ARCH IMPLANT WORKFLOW

The ioConnect system takes a unique approach by using flat, horizontally aligned scan bodies that reduce the distance between implant reference points—significantly increasing scan accuracy.

Here’s how it works at a high level:

  1. Attach the ioConnect scan flags
    The clinician places TruAbutment’s elongated flat scan bodies on the implants. They’re available in six kit variations to match different multiunit diameters.
  2. Align the scan bodies across the arch
    Once positioned, the flags sit in a unified plane, creating a highly scannable geometry.
  3. Scan only the centered hexes
    With TRIOS’s updated scanning algorithm, the elongated flags are captured quickly and accurately.
  4. Process the data in TruAbutment's TruSuite software
    The software computes the precise spatial relationships and angulations of the implants.
  5. Export as STL to 3Shape Dental System
    The result is a CAD ready file opened in 3Shape Dental System CAD software for predictable, precision based restorative design.
