The biology of tooth movement has not changed, but the workflow around it has — and that has real benefits for patients.

The three scanners most commonly found in UK specialist orthodontic practices are the iTero Element (used extensively by Invisalign providers), the 3Shape Trios (popular with in-house lab workflows), and the Dentsply Primescan. Each scanner captures thousands of images per second using structured light or laser triangulation, building a three-dimensional digital model of your teeth in real time. Most full-arch scans take between three and eight minutes per arch. The resulting STL file is accurate to within 50–100 micrometres, which is comparable to or better than a well-poured plaster model. ## How do digital impressions compare to traditional alginate? Alginate impressions involve placing a tray loaded with a thick paste into the mouth and waiting roughly two to three minutes while it sets. Common complaints include gagging, a strong taste, and potential distortion if not poured quickly. Digital impressions eliminate all of these steps. There is no material in the mouth beyond a slim wand. The scan can be reviewed on screen immediately, and any area that is unclear can be rescanned in seconds. The digital file is transmitted to the lab instantly, shortening turnaround times significantly. Patients who previously struggled with gag reflex during alginate impressions often find intraoral scanning a markedly better experience. ## How does ClinCheck treatment simulation work? ClinCheck is the proprietary simulation software used by Invisalign. Once a scan is submitted, Align Technology's technicians produce a digital set-up showing the predicted movement of each tooth from start to finish, broken into stages corresponding to each aligner tray. The orthodontist reviews this set-up and makes modifications before approving it. What the simulation shares in common with other digital planning systems is that the clinical decision-making happens away from the patient, with the orthodontist refining the plan on screen. The value to the patient is the ability to see a preview of the intended outcome before any appliance is fitted. ## How do patients review and approve their digital treatment plan? Most digital orthodontic workflows include a step where the patient reviews the planned outcome before treatment begins. For aligner therapy this typically happens at the consultation or a separate records appointment: the orthodontist shows the ClinCheck or equivalent video, discusses the number of aligners and estimated duration, and invites questions. Patients can ask about specific teeth and whether the simulation shows an aesthetic result they are comfortable with. Approving the digital plan does not create a legal guarantee of outcome, but it does form part of the consent process. ## How is 3D printing used in orthodontics? Three-dimensional printing has moved from the laboratory to chairside in many UK specialist practices. Once a digital model exists, a clear retainer or removable appliance can be fabricated without any new impressions. Essix-type retainers are increasingly printed or thermoformed over a printed model rather than over a plaster one, improving consistency and allowing reprints without recalls. The speed advantage is significant: a printed retainer can often be ready within 24 to 48 hours of the scan rather than the five to seven days needed when sending impressions to an external lab. ## When is CBCT cone beam CT used in digital orthodontic planning? Cone beam CT provides a three-dimensional X-ray volume of the teeth, roots, bone, and surrounding structures. In routine orthodontic cases it is not required — UK guidance from the Faculty of General Dental Practice recommends CBCT only when the clinical question cannot be answered by conventional two-dimensional imaging. Cases where CBCT is commonly justified include: impacted canines where exact root position needs to be mapped; patients with significant skeletal discrepancy being planned for jaw surgery; suspected root resorption; and patients with missing teeth where implant placement may follow orthodontic space creation. ## Does digital orthodontics produce better clinical outcomes? Digital orthodontic workflows improve the process around treatment — they make planning more predictable, communication clearer, and some elements faster. They do not change the biological limits of tooth movement. Teeth move through bone at roughly one millimetre per month regardless of how the treatment was planned. What digital planning can improve is the precision of bracket placement or aligner fit, which may reduce the number of mid-course corrections needed. If a practice is claiming that its digital tools produce measurably better clinical results than a non-digital specialist practice, treat that claim with scepticism unless they can cite specific evidence. ## Useful related pages [Digital Scan vs Impressions UK](https://virtualconsultant.online/guides/digital-scan-vs-impressions-orthodontics-uk) [CBCT vs OPG X-ray UK](https://virtualconsultant.online/guides/cbct-vs-opg-xray-uk) [Orthodontic Treatment Plan UK](https://virtualconsultant.online/guides/orthodontic-treatment-plan) [Clear Aligner Tracking UK](https://virtualconsultant.online/guides/clear-aligner-tracking-uk) [Questions to Ask Your Orthodontist](https://virtualconsultant.online/guides/questions-to-ask-orthodontist) This guide is for general information only.

No. Scanner adoption is high among specialist orthodontic practices but not universal. Some practices still use alginate impressions, particularly for NHS treatment where the scanner investment may not be funded. If digital records matter to you, confirm this before booking. The absence of a scanner does not mean a practice cannot deliver excellent orthodontic treatment — clinical skill remains more important than equipment. Is an intraoral scan less accurate than a plaster model? Modern intraoral scanners are accurate to within 50 to 100 micrometres across a full arch, which is comparable to a well-poured plaster model. In practice, errors in pouring or trimming conventional impressions mean that digital scans are often more consistent. For clear aligner manufacture in particular, digital scans produce better-fitting trays with fewer early tracking problems than well-made alginate impressions. Can I see my ClinCheck simulation before paying? Many practices show a preview or indicative simulation at the consultation stage. A full ClinCheck requires the scan to be submitted and the set-up produced, which typically happens after a deposit is paid. Ask what the consultation process involves and whether an indicative simulation can be shown before you commit to full treatment, so you have a sense of the planned approach and projected outcome. Will a 3D-printed retainer last as long as a lab-made one? Retainers printed from biocompatible resin or thermoformed over a printed model have comparable durability to lab-made equivalents. The material and fit matter more than the manufacturing method. Follow your orthodontist's guidance on replacement intervals — most clear retainers need replacing every one to three years regardless of how they were made, and replacement is easier and faster when a digital model is already on file. Does having a digital workflow cost more? Practices with intraoral scanners and digital workflows often charge slightly more than those without, reflecting the equipment investment. The cost difference is rarely itemised separately — it is absorbed into the overall treatment fee. For complex cases the accuracy benefits can reduce the number of refinements or adjustments needed, which has a cost offset over the course of treatment. What should I ask about digital technology at my orthodontic consultation? Ask whether the practice uses an intraoral scanner for records, and which model. Ask whether you will be shown your digital treatment plan before approving it. Ask whether retainers are made from digital models, and if you lose a retainer whether a replacement can be made without coming in. Ask how long it typically takes from consultation to start of treatment with their digital workflow. These questions help you understand whether digital tools are genuinely integrated into the clinical process. Explore your options Quick links Not sure where to start?
