# Orthodontic Acceleration Devices: Evidence and Reality

Most acceleration devices are sold with impressive marketing claims, but only some have randomised controlled trial support. This evidence-based review covers every major device category available to UK patients — from vibration appliances to surgical techniques — and explains what the science actually shows about treatment-time reduction.

## Why tooth movement takes time

Orthodontic tooth movement is a biological process, not a mechanical one. Force applied by braces or aligners triggers an inflammatory response in the periodontal ligament (PDL), which stimulates osteoclasts and osteoblasts to resorb and deposit bone on either side of the tooth root. This cellular remodelling process has an inherent rate limit — roughly 1 mm per month under optimal conditions. Acceleration devices aim to upregulate this biological activity, either by increasing the frequency of mechanical stimulation, triggering local bone trauma, or using light or vibration to enhance cellular activity. The key question is whether any of them meaningfully speed this process in clinical practice.

## High-frequency vibration: VPro5 and AcceleDent

High-frequency vibration (HFV) devices — including the VPro5 (Propel) and AcceleDent (OrthoAccel) — deliver low-level vibration at frequencies of 30 Hz (AcceleDent) or 120 Hz (VPro5), typically for 5 to 20 minutes per day. The theoretical basis is that vibration enhances PDL cellular activity and increases bone remodelling rate. In practice, the clinical trial evidence is weak. The 2016 Cochrane systematic review on AcceleDent found very low-quality evidence and no clinically significant reduction in treatment time in controlled trials. Multiple RCTs since then have similarly failed to demonstrate meaningful time savings. The VPro5, despite aggressive marketing, has no published RCT evidence demonstrating treatment-time reduction. Both devices are sold directly to patients in the UK for £200 to £600. Independent clinical organisations including the BOS have not endorsed these devices.

## Micro-osteoperforations: Propel

Micro-osteoperforations (MOPs) involve creating small perforations in alveolar bone adjacent to teeth using a device such as the Propel system. This induces a localised regional acceleratory phenomenon (RAP) — an upregulation of bone remodelling activity in the surrounding bone. Several RCTs have shown meaningful reductions in tooth movement time for specific tooth movements (particularly canine retraction) when MOPs are used. A 2019 systematic review found moderate evidence supporting MOPs for reducing canine retraction time by 30 to 44%. MOPs are performed chairside by the orthodontist and are not patient-administered devices. They are available in some UK private practices at an additional cost of £100 to £300 per session. The procedure is mildly uncomfortable and requires local anaesthetic for some patients.

## Photobiomodulation and low-level laser therapy

Photobiomodulation (PBM), also called low-level laser therapy (LLLT), uses light energy to stimulate cellular activity in periodontal tissues. In vitro studies show it can increase osteoblast and osteoclast activity. Small RCTs have reported 20 to 30% reductions in treatment time for specific tooth movements, but study populations are generally small, follow-up is short, and protocols vary widely between studies, making direct comparisons difficult. A 2020 systematic review rated the overall evidence as low to moderate quality. PBM devices for home use (such as the Biolux OrthoPulse) are marketed in the UK at approximately £500 to £800. In-practice PBM is available at a small number of UK specialist practices. The GDC and BOS have not issued guidance specifically endorsing PBM as standard care.

## Surgical acceleration: corticotomy and PAOO

Surgically assisted acceleration involves deliberately injuring alveolar bone to trigger a robust RAP. Corticotomy (cutting the cortical plate of bone) and piezoelectric micro-osteotomy are the most common techniques. Periodontally accelerated osteogenic orthodontics (PAOO) combines corticotomy with bone grafting. These procedures can reduce treatment time substantially — by 50 to 60% in some published case series — but they are invasive, require a surgical procedure under local anaesthetic, carry risks (pain, swelling, infection, gingival recession), and increase overall treatment cost significantly. They are typically used for adult patients with complex tooth movements where rapid treatment is a clinical priority, not for routine cases.

## Cost comparison and realistic expectations

VPro5 or similar HFV devices: £200 to £600, evidence weak, no endorsement from BOS. AcceleDent: £300 to £500, Cochrane review inconclusive. MOPs (Propel): £100 to £300 per session, some RCT support for specific movements. PBM home device: £500 to £800, moderate evidence, protocols inconsistent. Surgical acceleration: £1,500 to £3,000+, best evidence for time reduction but most invasive. For most patients, the honest answer is that well-executed orthodontic treatment, consistent aligner wear (for aligners), and attending appointments on time will have more impact on treatment duration than any commercially available acceleration device.

## Questions to ask before purchasing

Before buying an acceleration device, ask your orthodontist whether they recommend it for your specific case, what their clinical experience with it is, and whether there are published RCTs supporting its use for the tooth movements you need. Ask what realistic time savings you can expect in weeks, not percentages. Ask whether the device is an adjunct to their protocol or something you are purchasing independently. A clinician who cannot point to peer-reviewed evidence or who endorses a device they have no clinical experience with should prompt further questions.

### Frequently Asked Questions

Do orthodontic vibration devices like VPro5 actually work?

The evidence for high-frequency vibration devices is weak. The Cochrane systematic review on AcceleDent found very low-quality evidence and no clinically significant reduction in treatment time. The VPro5 has no published RCT evidence demonstrating treatment-time reduction. Independent clinical organisations including the British Orthodontic Society have not endorsed these devices. Manufacturers market them with testimonials and small uncontrolled studies, which are not reliable evidence.

What is the best-evidenced method to speed up orthodontics?

Micro-osteoperforations (MOPs), performed by your orthodontist, have the strongest RCT evidence for specific tooth movements such as canine retraction. Surgical acceleration (corticotomy, PAOO) has the most substantial evidence for overall treatment-time reduction, but it is invasive and not appropriate for most patients. For non-invasive options, photobiomodulation has some supporting evidence but lacks consistent protocols. No widely available home device has strong, independent evidence.

Can I buy an acceleration device without telling my orthodontist?

You can, but it is not advisable. Some devices (such as high-frequency vibration appliances) fit over aligners or braces and could theoretically affect the fit of aligners if used incorrectly. More importantly, if a device does have any effect on tooth movement, your orthodontist needs to know about it to monitor your progress appropriately. Always tell your orthodontist what adjuncts you are using.

How much can orthodontics actually be accelerated?

Realistic time savings vary significantly by method. MOPs may reduce specific tooth movement time by 30 to 44% in RCTs. Surgical approaches can reduce overall treatment by 50 to 60% but are invasive. Home vibration devices show minimal to no effect in controlled trials. The most evidence-based way to keep treatment on track is to attend appointments on time, wear aligners for the recommended 22 hours per day (if applicable), and follow all clinical instructions. These non-device factors often matter more in practice.

Does the NHS offer accelerated orthodontic treatment?

No. NHS orthodontic treatment in the UK follows standard protocols and does not offer acceleration adjuncts. Surgically assisted acceleration, MOPs, and photobiomodulation are private procedures. If treatment speed is a priority, you will need to discuss private options with a specialist orthodontist.

Is photobiomodulation (OrthoPulse) worth buying?

The evidence for photobiomodulation is more promising than for vibration devices, but still limited in quality and consistency. Small RCTs show potential benefits for specific movements. The OrthoPulse device costs £500 to £800 in the UK, and there is no guarantee it will shorten your specific treatment. If you are considering it, discuss with your orthodontist first — they can tell you whether the device is compatible with your treatment type and whether there are case-specific reasons it might or might not help.

What is the GDC and BOS position on acceleration devices?

The GDC has not issued specific guidance on acceleration devices. The British Orthodontic Society has not formally endorsed any commercially available patient-administered acceleration device. Orthodontists are expected to follow evidence-based practice, and recommending a device that lacks high-quality evidence without appropriate informed consent would be inconsistent with GDC standards. If a practice is strongly pushing an expensive device, it is reasonable to ask for the evidence.
