From a clinical standpoint, many multi-chair dental practices are increasingly adopting multiple <a href="https://repair.dental/services/intraoral-scanner-repair/align-technology-intraoral-scanner-repair">Align Technology intraoral scanners</a> to streamline digital workflows. However, simultaneous operation of multiple scanners can lead to network conflicts, resulting in intermittent connectivity, scan interruptions, and delayed data transfer to workstations.In daily practice, I&rsquo;ve observed clinics where scans abruptly freeze mid-arch, forcing operators to restart scanning sessions, increasing chairtime, and occasionally requiring rescans. Multi-scanner conflicts don&rsquo;t just slow workflow&mdash;they also introduce the risk of stitching errors, which may affect restorative case accuracy.Most dentists don&rsquo;t realize that these conflicts often originate from simple network misconfigurations rather than hardware failures. Misaligned Wi-Fi channels, overlapping IP addresses, and insufficient bandwidth are common culprits. Left unresolved, they disrupt patient scheduling, reduce staff efficiency, and can even impact lab collaboration for digital impressions. Understanding the common mistakes, root causes, and practical preventive strategies ensures smooth operation across multiple Align Technology scanners, preserving workflow efficiency and clinical accuracy.

<h2 style="text-align:justify">Common Mistakes:</h2>

<h3 style="text-align:justify">&nbsp;</h3>

<h3 style="text-align:justify">1. Overlapping IP Addresses</h3>

Many practices fail to assign unique IP addresses to each scanner. When multiple devices attempt to use the same IP, the network cannot route scan data correctly, resulting in intermittent connectivity or dropped sessions.

<h3 style="text-align:justify">2. Single Access Point Overload</h3>

Using a single Wi-Fi access point for multiple scanners is a frequent mistake. While one scanner may operate flawlessly, adding additional devices often exceeds the bandwidth, causing slowdowns or dropped connections during scanning.

<h3 style="text-align:justify">3. Ignoring Network Segmentation</h3>

Clinics sometimes integrate scanners into the general office Wi-Fi network. This exposes devices to interference from other electronics, leading to unpredictable connectivity and conflicts between scanners.

<h3 style="text-align:justify">4. Outdated Scanner Firmware</h3>

Operators may neglect to update scanner firmware. Older firmware may not handle multiple device communication efficiently, increasing the likelihood of network collisions.

<h3 style="text-align:justify">5. Improper Router Settings</h3>

Default router configurations, such as DHCP lease times or firewall restrictions, can block scanner traffic or cause IP reassignment mid-session, interrupting ongoing scans.

&nbsp;

Dentist Insight: Most dentists assume connectivity issues indicate scanner failure. In reality, many network conflicts are environmental and preventable, requiring adjustments to clinic&#39;s IT infrastructure rather than hardware replacement.

<h2 style="text-align:justify">&nbsp;</h2>

<h2 style="text-align:justify">Why do they happen?</h2>

&nbsp;

Understanding the root causes is essential for long-term prevention. Network conflicts occur primarily due to interference, bandwidth limitations, and miscommunication between devices and workstations.

<ul>
	<li style="text-align:justify">IP Address Collisions: When two scanners share an IP address, packets are dropped or misrouted. The scanners may appear online but fail to transfer scan data reliably. 
	&nbsp;</li>
	<li style="text-align:justify">Wi-Fi Channel Congestion: Many scanners operate on 2.4 GHz or 5 GHz frequencies. Multiple devices on the same channel compete for bandwidth, causing intermittent connectivity. 
	&nbsp;</li>
	<li style="text-align:justify">Firewall and Security Settings: Corporate or clinic network firewalls may block certain ports required for scanner communication. Without proper configuration, scanners cannot maintain consistent data transfer. 
	&nbsp;</li>
	<li style="text-align:justify">Firmware and Software Incompatibility: Firmware that does not support multi-device operation or workstation software not updated for new OS protocols can lead to session freezes. 
	&nbsp;</li>
</ul>

&nbsp;

Clinical Impact: In multi-chair environments, these conflicts increase chairtime, disrupt patient scheduling, and risk scan errors. Repeating scans not only wastes time but can also increase patient discomfort and reduce lab efficiency.From a clinical workflow perspective, resolving network conflicts is far more efficient than replacing scanners unnecessarily. Identifying why conflicts occur allows for targeted solutions, minimizing downtime and maintaining case accuracy.

<h2 style="text-align:justify">&nbsp;</h2>

<h2 style="text-align:justify">How to Avoid?</h2>

<h3 style="text-align:justify">&nbsp;</h3>

<h3 style="text-align:justify">1. Assign Static IPs</h3>

Assign unique static IP addresses to each scanner. This eliminates collisions and ensures that workstations can consistently communicate with each device.

<h3 style="text-align:justify">2. Dedicated Access Points</h3>

Install separate Wi-Fi access points for scanner traffic. Prioritize these access points for Align Technology scanners to avoid interference from office electronics or mobile devices.

<h3 style="text-align:justify">3. Network Segmentation</h3>

Segment scanner traffic from the general office Wi-Fi. Use VLANs or isolated networks to reduce interference and ensure uninterrupted data flow between scanners and workstations.

<h3 style="text-align:justify">4. Update Firmware Regularly</h3>

Maintain the latest firmware on all scanners. Updates often include improvements for multi-device operation, enhancing stability and reducing communication errors.

<h3 style="text-align:justify">5. Optimize Router Settings</h3>

Adjust DHCP lease times and open required ports. Confirm that firewall settings permit scanner communication. This ensures consistent data transfer without mid-session disconnections.

<h3 style="text-align:justify">6. Monitor Bandwidth Usage</h3>

Regularly monitor network bandwidth. If multiple scanners or other digital devices are active, ensure sufficient capacity to handle peak scanning periods.

&nbsp;

Dentist Insight: Staff training is crucial. Even with the best network setup, improper handling&mdash;such as moving scanners too far from access points&mdash;can degrade performance. Educating team members on optimal scanner positioning and network usage preserves workflow efficiency.
