AI Features And Intelligent Processing

Artificial intelligence plays a central role in Primescan 2's performance and represents a key differentiator in its cloud-native architecture. Research published in the Journal of Dental Research has demonstrated that AI can significantly enhance diagnostic accuracy in dental applications, and Primescan 2 leverages multiple AI systems that work together to deliver clinical results.

AI-Powered Scan Stitching

The stitching AI in Primescan 2 ranks among the strongest in the industry. This advanced algorithm assembles thousands of individual images into cohesive 3D models with remarkable accuracy, resulting in a very low incidence of double images, a common problem that affects many competing scanners. The cloud-based nature of this processing means Dentsply Sirona can continuously improve the algorithm, with updates deployed globally to every Primescan 2 in the field simultaneously.

Intelligent Tracking Recovery

When tracking is lost during scanning, the AI-driven recovery system typically re-acquires position quickly without requiring a complete restart. The system can recover from brief interruptions in most cases, though occasionally the scan visualization may rotate or shift unexpectedly when orientation is lost. This intelligent recovery significantly reduces chair time compared to scanners that require manual realignment after tracking loss.

AI Caries Detection Capabilities

The caries detection system uses AI-enhanced imaging across multiple modalities. According to a systematic review published in PMC/National Library of Medicine, AI-assisted caries detection has demonstrated accuracy rates between 73.3% and 98.6% across various datasets, with convolutional neural networks (CNNs) showing particular promise for clinical applications.

The Primescan 2 employs three distinct imaging modes powered by intelligent processing:

• White light photography: High-resolution intraoral camera captures detailed visual documentation, automatically stored in the cloud and accessible through DS Core for patient communication and longitudinal monitoring

• Fluorescence imaging (405nm): Demineralized enamel and bacterial by-products alter fluorescence signals, rendered as contrast areas commonly appearing as red zones against a green background, with AI processing highlighting potential lesions

• Near-infrared imaging (850nm): NIR penetrates enamel more effectively than visible light, revealing subsurface anomalies with AI processing that helps identify early proximal lesions and enamel cracks

Soft-Tissue Recognition

The AI includes soft-tissue filtering to distinguish between tooth structure and surrounding tissues. However, this filtering is less aggressive than in some competing systems. The scanner tends to capture adjacent soft tissues such as cheeks and tongue more readily, which places greater emphasis on effective retraction during scanning. While rescanning typically removes captured soft tissue, this characteristic requires operators to maintain good retraction technique throughout the scanning process.

Future AI Development Potential

The cloud-native architecture positions Primescan 2 uniquely for future AI enhancements. Because all processing occurs on DS Core, Dentsply Sirona can deploy improvements to contrast enhancement, automated lesion detection, AI-assisted triage, and predictive diagnostics without requiring hardware changes. This means every Primescan 2 in the world can immediately benefit from new AI capabilities as they are developed. As research in dental AI continues to advance, DS Core updates could refine sensitivity and specificity over time, potentially making Primescan 2 an increasingly valuable diagnostic tool.

Primescan 2 Scan Speed And Performance

Scanning speed has always been one of the defining strengths of the Primescan platform, and Primescan 2 continues that tradition while introducing the complexity of cloud-based processing. Understanding how network conditions affect performance helps practices optimize their scanning workflows.

In terms of pure capture performance, the scanner operates at a level comparable to Primescan 1, which remains one of the fastest and most accurate intraoral scanners currently available. From a hardware standpoint, this is expected because the scanning engine itself has not been fundamentally redesigned. The core optical technology remains the same, with the primary innovation being the wireless, cloud-based processing workflow.

Under optimal network conditions, the cloud processing approach works remarkably well. The live scan view responds quickly, tracking is stable, and the overall experience closely mirrors that of a traditional wired scanner. A full-arch scan can be completed in under 60 seconds while delivering excellent accuracy. The large scanning field of view (16×16mm) enables rapid coverage of arches and reduces the need for excessive rescanning. Processing times typically range from 20 to 60 seconds, depending on dataset size.

However, cloud-based performance introduces a new dependency on network reliability. Lag, even when minimal, has a disproportionate impact during intraoral scanning. A slight delay between scanner movement and visual feedback can disrupt scanning flow, increase the likelihood of tracking loss, and slow down longer scan sequences. In more complex scans, such as edentulous cases or full-arch implant workflows, performance becomes more sensitive to connectivity because these require longer continuous capture sequences.

Size And Ergonomics

Primescan 2 stands out immediately in the intraoral scanner market due to its physical presence. The scanner's dimensions and weight represent deliberate design choices that prioritize performance and wireless capability over compact form factor.

At 542 grams (1.2 pounds), the scanner is currently the heaviest wireless option in its class, almost 100 grams heavier than its predecessor, which already had a reputation for being relatively large. Many competing scanners weigh roughly half as much, with some of the latest designs falling in the 230–280 gram range. This design choice reflects a clear prioritization of scanning performance and system stability, as the Primescan 2 is essentially a Primescan 1 adapted for a fully wireless, cloud-based workflow, requiring additional internal components, including batteries, active cooling, wireless hardware, and additional sensors.

Build quality is exceptional, with tight tolerances, seamless panel joins, and a solid premium finish. The scanner tip has been redesigned with a narrower profile than Primescan 1, improving access to posterior teeth and interproximal spaces. This narrower distal end reduces awkward angulation during distal molar capture while maintaining the same optical coverage. For practices performing many posterior or full-arch cases, this change materially enhances intraoral access and clinical efficiency.

Scanner Tips And Calibration

Primescan 2 ships with single-use scanning sleeves rather than relying solely on autoclavable tips, a departure from previous Dentsply Sirona norms. This approach offers both advantages and cost considerations that practices must evaluate based on their clinical volume and workflow preferences.

Disposable sleeves arrive sterile and free of micro-abrasions, ensuring consistent optical clarity from one patient to the next. A typical retail pack of 30 sleeves is priced around $105 USD, equating to approximately $3.50 per scan. A metal tip option is available separately for practices preferring a feel closer to legacy Primescan and Omnicam designs. While not autoclavable, the metal tip lowers per-case consumable expense. Selection should factor in sterilization capacity, per-scan economics, clinic sustainability goals, and local infection control regulations.

Calibration remains essential to preserve accuracy. The system includes a calibration unit, with manufacturer guidance typically recommending monthly calibration. Best practice includes a pre-calibration checklist (clean optics, stable network), execution of the vendor-specified routine, and a post-calibration validation scan. Important: Use the metal sleeve for calibration because disposable sleeves cannot be used for this purpose.

DS Core Platform And Software Ecosystem

DS Core represents a clear departure from traditional dental scanning software. Rather than operating on a dedicated workstation, it runs entirely within a web browser with a modern, simplified interface that reflects Dentsply Sirona's vision for the future of digital dentistry.

After logging in, clinicians can create or access patient records and begin scanning immediately. The user interface has been redesigned with clear separation between clinical tasks, patient data, and production workflows. The platform offers two primary scanning pathways: Status Scan for check-ups and baseline records, and Treatment Scan for restorative procedures. Status scans can later be reused as pre-operative data, meaning when a treatment scan is initiated at a future visit, the software can reference and incorporate earlier scans stored in the cloud.

Treatment Scan workflows branch into restoration, aligner, implant, and splint categories, each generating predefined scan windows tailored to the chosen indication. Post-processing options include SureSmile Simulator, Canvas communication app, direct transfer to inLab CAD or CEREC Chairside software, secure link sharing, and file exports in STL, PLY, and exocad-compatible formats. The Canvas app serves as a flexible digital workspace for importing scans, photographs, and annotations into a single interactive environment for patient communication. DS Core's full potential will be realized when cloud-based CAD design becomes available, potentially creating a genuinely end-to-end digital ecosystem.

Cost Analysis And Total Ownership

At $24,995 USD, Primescan 2 is positioned at the upper echelon of the intraoral scanner market, though slightly below competitors like TRIOS 5 (approximately $26,000) and iTero Lumina (approximately $30,000). Understanding the total cost of ownership helps practices make informed purchasing decisions.

The cloud-native design eliminates the need for specialized hardware, potentially saving $2,000–$3,000 compared with systems requiring dedicated computers. However, ongoing costs for subscriptions, consumables, and service plans must be factored into the total investment calculation.
