Intraoral Scanning for Orthodontic Workflows

Intraoral scanning helps an orthodontic clinic build a digital case record, from the first assessment to the laboratory handoff. Yet a scan file alone does not explain the whole case. Your team also needs clear bite records, clinical notes, and an agreed review process. In this guide, we connect initial model capture, patient communication, and file delivery. The aim is a record the treating clinician can check and the receiving team can understand.

Start by confirming the purpose of the visit: a study model, clear aligner assessment, retainer, or another orthodontic appliance. Then check the receiving provider's record requirements and the scanner's instructions for use (IFU). A digital intraoral scanner may offer different export options depending on its software and licence. Before committing a case, confirm the accepted workflow with the laboratory. You can also review AJAX Dental's intraoral scannerand ask about the model, software, and intended uses.

Follow the scanning sequence, working distance, and lighting guidance for the specific scanner. Then use that validated approach consistently across the team. Expose the required tooth surfaces and control pooled saliva with appropriate isolation and suction. For example, pause to retract the tongue if it blocks the lower anterior teeth. If tracking stops, return to a clearly recorded area and follow the recovery prompts. Avoid treating one fixed scan path as suitable for every device.

During a full arch scan, watch the live model for missing incisal edges, distal molars, and soft tissue that obscures teeth. In patients with brackets or fixed retainers, review the relevant tooth and appliance surfaces carefully. However, do not infer completeness from a smooth display alone. Rotate the model to inspect the required areas. If detail is missing, follow the software's approved rescan process before moving to the next record.

Once the clinician has reviewed the capture, use the digital model to explain the findings. Show the upper and lower arches, then point out the areas relevant to the assessment. For example, a clinician can rotate the model while discussing crowding or spacing. Keep the explanation tied to the individual case. A BMC Oral Health review describes patient and technician communication among the uses of optical impressions. This supports a clear discussion, without promising a specific treatment result.

Also, explain what the display represents: visible oral surfaces and the captured bite relationship. It does not replace the clinician's examination or any other records the case requires. If treatment software shows a proposed setup, distinguish that proposal from the current scan. Finally, record the patient's questions and the clinician's advice in the case notes. This gives colleagues context when they review the orthodontic record later.

Different tasks need different details, so agree the acceptance checks before exporting the intraoral scan. The table below is a practical starting point. Confirm the exact scope with the treating clinician and receiving provider. For example, an aligner submission may require clinical photographs and other records in addition to the dental models. Keep those requirements in the case checklist so the team can identify missing items while the patient is still available.

The 2023 review of intraoral scanning in orthodontics covered 35 studies, with mixed findings on accuracy. Its authors considered the technology suitable for orthodontic treatment planning and aligner fabrication. That is useful context for an aligner case, but it cannot tell you whether a particular lab will accept your files. Put the lab's submission requirements beside your checklist and resolve any differences before scanning.

A complete upper and lower scan can still produce a bite that looks wrong. Have the clinician compare the on-screen relationship with the mouth. Look for an unexpected open bite, a shifted midline, or an overlap that was not observed clinically. The device IFU and prescribed jaw relationship determine how to capture the bite, including whether bilateral buccal records are needed. Resolve a mismatch before releasing the models for planning.

Consider the colleague who opens the case tomorrow. They need to know which jaw relationship the clinician intended, particularly if it differs from the patient's usual closure. Record those instructions alongside the scan. If the patient moved or closed differently, the clinician should reassess the capture; a note cannot correct bad data. Use the scanner's recapture procedure when another bite record is needed.

Open the models you are about to send and look at the areas the lab needs. Include the last molars, required gingival borders, and both arches where the prescription calls for them. Trim stray tissue with the software's tools without cutting away needed anatomy. The receiving provider specifies the export format and submission route. Use the clinic's coded case identifier, arch, scan date, and version in file names. Keep the patient's identity in the clinic record and use the agreed secure submission channel.

For an aligner submission, the handoff might include the approved models, requested photographs, relevant radiographs, and the clinician's instructions. A fixed retainer or an area that was difficult to capture deserves a note. Ask the recipient to confirm that the package opens and nothing required is missing. If you later replace a file, identify the new version and state which earlier file it supersedes. Keep that reply with the case so the team has a record of what the lab accepted.

Set the scanner aside for reprocessing before preparing it for another patient. The tip's instructions determine whether it can be reused, how to clean it, and whether a heat-sterilization cycle is permitted. A disposable sleeve and a reusable tip need different handling, so check each component's IFU. Assign someone to complete the required surface cleaning and equipment checks as well. The next operator should be able to tell that the reset is complete.

When a record needs correction, identify which stage failed before repeating the whole appointment. For instance, a readable model can still have an incorrect bite or an incomplete submission. Use the following checks to guide the response:

Make the final check a handoff check: the clinician has reviewed the intraoral record, and the recipient has accepted the files or explained what is missing. Keep the response with the case. If the same attachment goes missing again, update the checklist where staff assemble the files.
