Wireless Cloud‐Based Intraoral Scanners in Dental Education: Security, Interoperability, and Pedagogical Implications

Digital dentistry has rapidly transformed clinical practice and dental education by enabling real-time data capture, collaborative workflows, and enhanced patient documentation. Among the most impactful innovations are wireless intraoral scanners (IOS) integrated with cloud-based platforms, which provide mobility, remote access, and streamlined digital workflows. In academic dental environments, these technologies offer unique opportunities for predoctoral and postgraduate education, including simultaneous teaching of multiple students, exposure to advanced CAD/CAM workflows, and integration into research protocols 1, 2. Despite these advantages, the adoption of wireless, cloud-integrated IOS in academic settings introduces significant challenges. Dental schools operate as multi-user environments, with students, faculty, and support staff accessing sensitive patient data. Ensuring robust security, regulatory compliance, and interoperability with clinical and research systems is critical 3, 4. Moreover, educators often face a gap between technological capability and curricular integration, which may hinder student training in data governance, cybersecurity awareness, and cross-platform digital workflows 2, 5. This perspective addresses the implications of wireless cloud-based IOS adoption in dental education, focusing on data security, interoperability, and pedagogical integration. By comparing leading IOS devices, evaluating regulatory compliance frameworks, and drawing parallels to other healthcare settings, this commentary aims to inform institutional decision-making and contribute to best practices in digital dental education. Cloud architecture: Some devices operate primarily through vendor-hosted cloud platforms (e.g., Medit Cloud, DS Core), while others allow hybrid workflows with local storage options (e.g., TRIOS 6) 1, 6. Data export and interoperability: Open file formats (STL, PLY, and OBJ) are increasingly standard, supporting CAD/CAM software, research analytics, and multi-platform integration. Proprietary or restricted formats limit flexibility and may impede cross-institutional collaboration 6, 7. Mobility and clinical usability: Wireless operation enhances multi-chair clinical teaching, enabling students to work simultaneously and instructors to review scans in real time 5. These features underscore the delicate balance between technological advancement and operational governance, highlighting the need for academic institutions to carefully consider device functionality, student training, and regulatory compliance. 3Shape TRIOS 6 integrates with the Unite Cloud platform but provides limited public documentation on encryption standards and cloud-hosting locations 1, 2. Dentsply Sirona Primescan 2 operates through the DS Core ecosystem; while described as HIPAA-aligned, vendor-released material offers few specifics on authentication or audit-logging practices 2, 8. DEXIS Imprevo supports wireless data exchange within the DEXIS IS Connect Cloud but lacks detailed disclosure of its encryption or key-management policies 1, 2. Aidite Infinity 5, a newer market entrant, advertises Wi-Fi and cloud functionality yet omits formal statements regarding data-protection certification or regional compliance 1, 3. Shining 3D Aoralscan Elite Wireless transfers data through the Shining 3D Dental Cloud and claims secure transmission, although published information on encryption layers or access-control protocols remains limited 4, 6. Medit i900 Mobility demonstrates the highest level of transparency, reporting HIPAA/GDPR compliance, AES-256 encryption, and role-based access control within its Medit Link Cloud environment 1, 4. Collectively, these examples highlight the variability of vendor communication regarding security governance and reinforce the need for institutional audits verifying access management, encryption methods, data-hosting jurisdiction, data retention and destruction, and compliance certifications prior to deployment in academic settings 3, 4, 8. Healthcare institutions, including dental schools, have long recognized the criticality of data governance. Lessons from hospital-based electronic health records (EHRs) highlight the importance of auditing vendor compliance, confirming hosting location, and verifying certifications such as ISO 27001 or SOC 2 audit reports 8, 9. Failure to rigorously assess these factors may expose institutions to data breaches, which can result in regulatory penalties and reputational risk. Role-based access control: Ensuring users have access only to data necessary for their tasks 4. Multi-factor authentication: Reducing unauthorized access, especially for remote cloud logins 3. Audit trails and data retention policies: Monitoring access, ensuring secure destruction, and maintaining transparency for institutional oversight 8. The dental education environment shares similarities with hospital residency programs and teaching clinics in medicine, where multi-user digital systems necessitate strict governance policies 9. Integrating cybersecurity and compliance training into curricula significantly enhances institutional security culture. Interoperability is essential for creating cohesive digital workflows across clinical, laboratory, and research settings. Standards such as Health Level Seven (HL7) and Digital Imaging and Communications in Medicine (DICOM) support cross-platform exchange of clinical and imaging data 7, 8. However, partial or proprietary implementations remain common in dentistry, creating potential silos 6. Open file formats (STL, PLY, and OBJ) facilitate interoperability with CAD/CAM software, simulation platforms, and research databases. Among the six scanners, 3Shape TRIOS 6 supports STL, PLY, DCM, and its proprietary 3oxz format; Dentsply Sirona Primescan 2 offers STL, PLY, and proprietary DXD (OBJ export not supported); Aidite Infinity 5, Shining 3D Aoralscan Elite Wireless, and Medit i900 Mobility all provide STL, PLY, and OBJ outputs. These open-format capabilities enable seamless integration into both educational and research workflows 1, 2, 5, 6, though proprietary formats may be required for native vendor-specific functions (Table 1). From a pedagogical perspective, exposing students to multi-platform workflows builds digital literacy, a skill increasingly essential for evidence-based practice and interprofessional collaboration. Analogous initiatives in medical radiology education demonstrate that hands-on experience with interoperable imaging systems enhances competency in clinical decision-making and research methodologies 9. Simulation exercises: Allowing students to practice scanning, export, and import workflows across software platforms 5. Digital ethics modules: Emphasizing data security, patient privacy, and professional responsibilities 3. Interdisciplinary projects: Engaging students in collaborative digital workflows with engineering, informatics, or biomedical research programs 6. Wireless IOS differ not only in cloud architecture and interoperability but also in physical dimensions and ergonomic design, factors that can significantly influence usability in pre-clinical laboratories and multi-chair clinical teaching. Figure 1 provides a visual comparison of selected scanners, highlighting differences in design and ergonomics. Beyond usability considerations, financial feasibility and operational planning are critical for academic adoption, as implementing these devices requires ensuring adequate student access and workflow efficiency. Institutional experiences suggest that sufficient scanner units should be provided to support shared use, structured student rotations, and non-simultaneous scanning across multiple clinical areas. In pre-clinical simulation laboratories, a typical student-to-scanner ratio of 4–5:1 can be applied, while in clinical settings, scanners are generally assigned per clinic zone rather than per dental chair, reflecting common digital workflow practices 10. Table 2 summarizes the physical characteristics, weight, and approximate US market cost of these scanners, providing context for institutional planning, resource allocation, and ergonomic considerations. 3Shape TRIOS 6 DEXIS Imprevo Aidite Infinity 5 Medit i900 Mobility Examining parallel healthcare disciplines reinforces the relevance of these considerations. In radiology, cloud-based imaging platforms have demonstrated both efficiency gains and vulnerabilities related to multi-user access 9. Likewise, hospital EHR systems highlight the consequences of insufficient interoperability, including workflow inefficiencies and potential diagnostic errors 8. Implementing standardized protocols for cloud integration 6, 7. Conducting vendor audits before device or software acquisition 1, 2. Providing structured training for students and faculty on security and interoperability principles 3, 5. By doing so, dental institutions can achieve both pedagogical effectiveness and compliance, ensuring that graduates are proficient in the digital competencies required for modern practice. Emerging technologies, such as federated learning and blockchain, hold promise for enhancing privacy, data integrity, and cross-institutional collaboration 4. Federated learning allows machine learning algorithms to operate on decentralized datasets without exposing sensitive patient information, potentially enabling multi-institutional research collaborations. Blockchain-based data governance can provide immutable audit trails for scan histories, supporting both compliance and research reproducibility 4. Additionally, initiatives like the Consortium for Oral Health-Related Informatics (COHRI) demonstrate the value of shared standards and governance frameworks 11. Widespread adoption of such frameworks could mitigate current fragmentation in interoperability and data management. Evaluating vendor readiness for emerging technologies 4. Engaging in multi-institutional consortia to develop best practices 11. Updating curricula to include emerging digital tools and governance concepts 5. Data Security: While cloud-based architectures improve efficiency, transparency in encryption, storage, and compliance is essential 3, 4. Institutions must conduct thorough vendor audits and implement robust access control policies 8. Interoperability: Open file formats and adherence to HL7/DICOM standards enable integration with clinical, research, and laboratory systems, supporting both teaching and scholarly activity 6, 7. Pedagogical Integration: Incorporating security, digital literacy, and multi-platform workflows into curricula prepares students for contemporary practice and interdisciplinary collaboration 5. Future Technologies: Blockchain, federated learning, and shared governance initiatives may further enhance privacy, security, and interoperability, reinforcing the need for forward-looking institutional strategies 4, 11. By balancing technological capability with regulatory oversight and curricular integration, dental schools can maximize the educational benefits of cloud-based IOS while minimizing risks. This approach ensures that graduates are equipped not only to utilize digital tools effectively but also to uphold patient confidentiality, comply with regulations, and contribute to the ongoing evolution of digital dentistry.
