Clear aligner treatment in Surbiton
If you’ve been researching clear aligners, you’ve almost certainly come across three very different things being sold as if they were the same: Angel Aligners, Invisalign®, and the growing category of DIY or mail-order aligners delivered to your door. Two of those are professional orthodontic treatments. One of them isn’t.
We’ll explain what genuinely separates these options, what doesn’t, and why the most important decision you make has very little to do with the brand name on the box.
Invisalign® is a registered trademark of Align Technology, Inc. SmartDontics is not an Invisalign provider and is not affiliated with Align Technology. The comparison below is provided for patient information.
Angel Aligners and Invisalign are both professional, prescription-only orthodontic systems. Whichever you’re treated with, the process looks broadly the same:
Everything in that list is what you’re actually paying for. The aligner itself is the cheapest part of the process.
Two good systems, doing the same job
Let’s be straightforward: Invisalign is an excellent system. It’s the most established clear aligner brand in the world, it’s backed by decades of clinical use, and in skilled hands it produces outstanding results. Any orthodontist who tells you otherwise is selling something.
Angel Aligners does the same job, using the same principles. Both are sequential clear aligner systems: a series of custom-made trays, each shaped slightly differently from the last, moving your teeth in small, planned increments. Both are removable. Both are used with attachments and elastics for more demanding cases. Both are planned digitally from a 3D scan and reviewed by your clinician before a single aligner is made.
Where do they actually differ?
Aligner material and finish. Each manufacturer uses its own proprietary polymer with its own force characteristics. Angel Aligners have a frosted, anti-reflective surface that makes them particularly discreet in photographs and video calls, and the trays are hand-trimmed and polished at the edges for comfort.
Planning software. Each system has its own digital planning platform. Your orthodontist prescribes the movements; the software builds the sequence.
Track record. Invisalign has been in the UK market longer and has the larger published evidence base. Angel Aligners is a newer entrant to the UK, though the technology is well-established internationally.
What difference does that make to your result? In practice, far less than most patients expect. Multiple studies comparing aligner systems have found outcomes are driven overwhelmingly by diagnosis, treatment planning and clinician experience — not by which manufacturer produced the trays. Two patients with identical bites can get very different results from the same brand, treated by different clinicians.
We chose Angel Aligners because the material performs, the aesthetics are excellent, and the value it lets us pass on to patients is better. If you’re deciding between a practice offering Angel and a practice offering Invisalign, compare the orthodontists, not the brands.
This is where the comparison stops being close
Direct-to-consumer aligners — the ones advertised on social media, ordered online, with animpression kit posted to your home — are a fundamentally different proposition. Not acheaper version of the same thing. A different thing.
There is no in-person clinical assessment. Decay, gum disease, root problems and bite issues that would change or halt a treatment plan simply go undetected. Moving teeth through unhealthy bone is how patients lose them.
Root length and bone level determine how much movement is safe. Without that information, treatment is being planned blind.
An inaccurate mould produces inaccurate aligners, and you have no way of knowing which you’ve made.
Tooth movement is not a fixed process — it needs monitoring and adjusting. Unsupervised aligner treatment has been linked to irreversible root resorption, bite collapse, gum recession, jaw joint problems and, in patients with existing gum disease, tooth loss.
SmileDirectClub — for years the largest company in this market — ceased trading in late 2023, leaving patients worldwide mid-treatment with no clinician, no refunds and no aftercare. Many of those patients ended up in specialist practices like ours, paying a second time to correct the damage.
The British Orthodontic Society and the General Dental Council have both raised concerns about direct-to-consumer orthodontics. Orthodontic treatment is the practice of dentistry: in the UK it should involve a GDC-registered clinician who has examined you in person and who remains responsible for your care throughout.
If a clear aligner treatment doesn’t involve a clinician who has physically examined you, the saving isn’t a saving. It’s a risk you’re carrying yourself.

Every clear aligner brand markets itself on the tray. Almost none of them market the thing that actually determines your result: who plans the treatment.
A specialist orthodontist has completed three additional years of full-time postgraduate training in tooth movement, facial growth and bite mechanics, and is registered on the GDC’s Specialist List in Orthodontics. A general dentist offering aligners has not — and that isn’t a criticism, it’s simply a different scope of practice.
That training is what determines:
Dr Darsh Patel is a Specialist Orthodontist with 20 years of experience, an international lecturer on orthodontic technique, and has straightened over 500,000 teeth. When you’re comparing practices, that’s the specification worth reading — not the brand of plastic.
Patients often ask me why I now recommend Angel Aligners for many cases instead of Invisalign.
Having treated thousands of orthodontic patients over the years using a variety of aligner systems, I’ve learnt that the brand of aligner is only one part of achieving an exceptional result. My responsibility as a Specialist Orthodontist is to choose the system that I believe will give each patient the best clinical outcome – not simply the best-known brand.
As an Angel Aligner lecturer, I teach other clinicians how to use the system effectively and stay closely involved with its ongoing development and clinical education. This gives me first-hand insight into the latest techniques and innovations, allowing me to bring that knowledge directly to my patients at SmartDontics.
Today, for many suitable patients, that system is Angel Aligners.
The honest answer to “which aligner is best?” is that it depends on your teeth, your bite and your goals — and nobody can tell you that from a website.
At your free consultation in Surbiton, you’ll meet Dr Darsh Patel, have your smile assessed properly, see a 3D preview of your predicted result on our iTero scanner, and leave with a custom treatment plan and a clear price. There’s no obligation to go ahead, and no pressure if you don’t.
If you’re currently mid-treatment with a mail-order aligner company and something doesn’t feel right, please book in. We see these cases regularly and we won’t lecture you — we’ll just tell you where you stand.
You may be left mid-treatment with no clinician responsible for your care — as happened to patients worldwide when SmileDirectClub ceased trading in 2023. With treatment at a registered practice, your orthodontist remains accountable for your result.
