Intraoral scanners face a range of technical issues that can affect their effectiveness in clinical settings. Scanning Limitations are a key concern, particularly when dealing with edentulous areas. These regions lack the distinct anatomical markers scanners rely on, making it harder to capture accurate data ^[15]. This becomes especially challenging for patients with multiple missing teeth or those requiring complete dentures.

Environmental factors can also interfere with scan accuracy. Conditions like ambient light, moisture, and even the translucency of certain dental materials can degrade scan quality ^[16]. Additionally, the depth of finish lines on abutment teeth can make it difficult to capture detailed information ^[16]. Achieving consistent results often requires strict control over these variables.

The operator’s skill level plays a crucial role in scan accuracy ^[15]. The effectiveness of a digital scan heavily depends on the scanning technique, and less experienced operators may struggle to produce reliable results. Scanning strategies that start with fewer common areas are more prone to errors during the stitching process, which can decrease overall accuracy ^[15]. Larger scanning areas further complicate stitching, making it harder to maintain precision ^[16].

Performance also varies between scanner models. For instance, research has shown that the TRIOS 4 scanner performs on par with traditional impressions, while the Emerald S scanner falls short compared to both conventional methods and other digital systems ^[15]. Moreover, scans of the maxillary arch tend to be more precise than those of the mandibular arch ^[15], which can complicate treatment planning for comprehensive cases.

Cloud storage is a critical area of focus. Australian healthcare providers must ensure that patient data is stored within the country to meet legal requirements ^[20]. This restriction can limit scanner options and potentially increase costs, as not all manufacturers offer local data storage solutions.

Multi-factor authentication has become a necessity for securing digital accounts containing patient information ^[20]. Practices must also implement robust encryption and access controls to prevent unauthorised access or data breaches ^[20]. Maintaining these security measures requires ongoing effort, including regular updates and staff training.

Risk management planning is another essential component. Practices need to identify vulnerabilities and develop strategies to mitigate risks like cyber-attacks or data breaches ^[20]. Resources such as the Australian Dental Association‘s Data and Information Management Checklist and Data Breach Response Plan can help guide these efforts ^[20].

The integration of intraoral scanners with other digital systems adds another layer of complexity. Each connection point increases the risk of security breaches, making regular monitoring and staff education critical. Human error remains one of the leading causes of data breaches, underscoring the importance of comprehensive training ^[20].

To stay ahead of evolving threats and regulations, practices must regularly update their risk management plans. The Office of the Australian Information Commissioner offers guidance, but the ultimate responsibility for compliance lies with individual practices ^[20]. Addressing these security challenges is essential for ensuring smooth and secure digital workflows in orthodontics.
