FDA Clears First Dental-Dedicated MRI System Following Successful Clinical Trial
核心洞察
The MAGNETOM Free.Max Dental Edition (搜索), developed by Dentsply Sirona (搜索) and Siemens Healthineers (搜索), becomes the first dental-dedicated MRI system to receive FDA clearance in the United States.
Clinical trials validated the system's effectiveness across multiple dental specialties including endodontics (搜索), periodontics (搜索), TMJ (搜索) disorders, tooth extraction (搜索), and orthodontics (搜索) with radiation-free imaging capabilities.
The ddMRI system demonstrates ability to differentiate active inflammation from healthy tissue, assess tooth pulp vitality non-invasively, and visualize dental structures with advanced soft tissue contrast in under 20 minutes.
Dentsply Sirona (搜索) and Siemens Healthineers (搜索) have achieved a significant milestone in dental imaging with the FDA clearance of the MAGNETOM Free.Max Dental Edition (搜索), the first-ever dental-dedicated MRI (ddMRI) system in the United States. This breakthrough follows successful completion of clinical trials that validated the system's potential across multiple dental specialties, marking a new era in radiation-free dental diagnostics.
Clinical Trial Validation Demonstrates Broad Applications
The clinical trial confirmed the ddMRI system's significant potential across endodontics (搜索), periodontics (搜索), TMJ (搜索) disorders, tooth extraction (搜索), and orthodontics (搜索). Key clinical highlights from the trial demonstrated the system's ability to differentiate active inflammation from healthy and scar tissue, enable non-invasive assessment of tooth pulp vitality to support chairside testing, and visualize teeth positioning in relation to neighboring teeth and nerves.
The system features specialized capabilities designed specifically for dental professionals, including a dental-specific field of view enabled by a dedicated dental coil and specialized software that focuses exclusively on dental structures, ensuring no brain tissue is visible while allowing accurate imaging of dental anatomy.
Advanced Soft Tissue Imaging Without Radiation
Prof. Don Tyndall, DDS, MSPH, PhD, FICD, FACD; Diplomate ABOMR, Professor of Diagnostic Sciences at University of North Carolina, who reviewed the clinical trial findings and collaborated in the FDA clearance process, emphasized the system's diagnostic advantages: "MAGNETOM Free.Max Dental Edition (搜索) represents a significant advancement in dental imaging, providing excellent insights into dental structures that were not readily visible in other imaging modalities, without the risks associated with ionizing radiation."
Tyndall noted that the ability to observe the same region of interest using different ddMRI imaging sequences provides significantly more information regarding pathological processes in hard and soft tissues, resulting in more accurate understanding of lesions. The clarity of soft tissue detail produced by ddMRI has clear potential to enhance diagnostic confidence in areas where current modalities have limitations.
Efficient Clinical Workflow Integration
The ddMRI system addresses practical clinical needs with streamlined patient preparation and an average workflow time of under 20 minutes, making it a highly efficient tool for clinical use. As an ionizing radiation-free modality with advanced soft tissue contrast, ddMRI complements existing intraoral, panoramic, and CBCT imaging by addressing diagnostic questions where soft tissue characterization is critical.
Industry Partnership and Development
The MAGNETOM Free.Max Dental Edition (搜索) was developed jointly by Dentsply Sirona (搜索), Siemens Healthineers (搜索), and leading scientists in Europe and the United States. Specifically designed to enhance dentomaxillofacial diagnostics, the system is primarily intended for hospitals, large clinics, and universities.
Dan Scavilla, President & CEO of Dentsply Sirona (搜索), observed: "This innovation is a powerful addition to our imaging portfolio, which includes Axeos, Orthophos SL, and Heliodent Plus, among others. We're proud to have contributed to developing the industry's first dental dedicated MRI and the advancement of diagnostic capabilities in the field."
Andreas Schneck, head of Magnetic Resonance at Siemens Healthineers (搜索), added: "We are dedicated to expanding the clinical impact and reach of MRI. We are excited to see the potential of ddMRI being validated through clinical trials, which will pave the way for a new clinical field that will benefit dental practitioners and patients alike."
Clinical Training and Implementation
Clinicians interested in incorporating ddMRI into their practice can participate in an advanced, hands-on training program scheduled for April 2026 at the University of Minnesota. The two-day course covers ddMRI imaging protocols, recommended clinical procedures, essential MR facility and patient safety guidelines, hands-on image acquisition, and practical interpretation sessions featuring TMJ (搜索) and dental cases.
The technology will be showcased at the American Dental Education Association (ADEA 2026) Annual Session, taking place March 21-24 in Montréal, Canada, where dental professionals can learn more about this first-of-its-kind dental-dedicated magnetic resonance imaging system.
