Planmeca Viso G7 Review – Ultimate Full-Face CBCT for Modern Dentistry

Why Viso G7 Matters in Digital Dentistry

Three-dimensional imaging has transformed how clinicians assess pathology, plan implants, analyze airways, and coordinate multidisciplinary treatment. As CBCT technology advances, the emphasis has shifted from simply acquiring volumes to capturing true anatomical context with minimal radiation and maximum diagnostic utility.

Planmeca Viso G7 represents the apex of this evolution within the Planmeca family. It combines a large flat-panel sensor, robust motion-correction algorithms, and flexible imaging volumes – all engineered to deliver comprehensive maxillofacial coverage in a single scan. For practices ready to leverage sophisticated imaging to elevate clinical outcomes, the Viso G7 offers capabilities that extend far beyond conventional devices.

This review will guide clinicians and practice leaders through what the Viso G7 does, how it performs across workflows, and whether it justifies its investment for advanced diagnostic imaging.

What Planmeca Viso G7 Delivers

At the heart of the Viso G7 is a 25 × 30 cm flat-panel detector that supports volumetric captures from small localized regions to broad maxillofacial and full-face volumes. This is one of the largest CBCT detectors currently available in dental imaging. The practical benefits include:

• Single-scan full face and jaw imaging

• Elimination of stitching artifacts

• Seamless integration with intraoral and facial surface scans

• Consistent geometric fidelity across large volumes

The ability to capture a 30 × 30 cm volume in one rotation reduces acquisition time and minimizes the cumulative radiation burden compared to multiple smaller scans stitched together.

Live Patient Positioning with Multi-Camera Views

Planmeca integrates four live cameras into the CBCT gantry that feed real-time visual positioning to the operator. This live field-of-view preview improves scan setup precision and reduces guesswork – a major advantage for larger volumes where alignment is critical.

The rear head support enhances patient comfort, stabilizes posture, and keeps the facial soft tissue visible for 3D surface capture.

Advanced Image Processing and Motion Correction

The Viso G7’s software suite includes:

• Planmeca CALM™ – a proprietary motion-correction algorithm that reduces motion artifacts

• Planmeca AINO™ and ARA™ – noise reduction and aliasing artifacts minimization

• Ultra Low Dose (ULD) imaging – decreases effective dose without compromising necessary diagnostic detail

This combination promotes sharper reconstructions, reduced retakes, and improved diagnostic confidence.

ProFace 3D Facial Surface Imaging

A distinctive element is ProFace – integrated 3D facial photography that can be registered with the CBCT volume. This multimodal capability enables:

• Facial soft-tissue correlation to skeletal anatomy

• Boosted communication with patients and specialists

• A more complete “virtual patient” view

For aesthetic planning, orthognathic simulation, and surgical consultations, coupling facial surface data with bone anatomy adds clarity that 3D volume alone cannot deliver.

Image Quality and Diagnostic Capabilities

At its core, the value of a CBCT system lies in what it reveals clinically.

The Viso G7 provides high spatial resolution, which enhances the clinician’s ability to:

• Visualize alveolar bone topography for implant planning

• Detect fine osseous details

• Assess cortical borders and trabecular architecture

Contrast across bone, soft tissue, and air spaces is clean, supporting diagnosis across a broad range of indications – from simple restorative imaging to advanced surgical mapping.

Motion Correction with CALM™

Patient movement is a significant source of distortion in 3D imaging, especially with larger fields or pediatric populations. The CALM algorithm identifies motion blurring in raw projection data and adjusts reconstruction to compensate.

This feature has practical utility in:

• Reducing repeat scans

• Reducing radiation exposure

• Improving diagnostic yield on first capture

Importantly, the algorithm is most effective with subtle motion – very large, abrupt movements may still challenge any motion correction implementation.

Ultra-Low Dose Protocols

The concept of “as low as diagnostically acceptable” radiation is foundational to modern radiology. The Viso G7’s ULD settings balance patient safety and image utility:

• Useful for screening applications

• Effective for airway evaluation and initial screenings

• Less so when micro-detail is required (e.g., fine root fractures)

Clinics should implement indication-specific protocols that match dose settings to diagnostic needs.

ProFace and Multi-Modal Imaging

Integrating facial surface data with 3D bone volumes is not merely aesthetic – it enhances diagnostic context. ProFace provides:

• Soft-tissue envelope data

• Support for consultative discussions

• A bridge from radiographic imaging to patient understanding

When integrated with facial scans and intraoral scans, it can create a fully registered digital patient model for planning and education.
