Angel Aligner has a portfolio of four purpose-built systems, each engineered for a different stage of orthodontic treatment. Knowing the difference helps make sense of why your orthodontist might recommend one system over another, or move you between systems as your treatment progresses.
Here’s what each one actually is.
Angel Aligner Select: The Everyday System
Angel Aligner Select is a versatile clear aligner system built to handle a broad spread of general alignment cases in teens and adults, from spacing and crowding through to more involved movements.
Select is powered by masterControl S, a multi-layer polymer engineered to balance flexibility and rigidity so it can manage a range of different tooth movement patterns within a single aligner material, rather than switching materials partway through treatment.
It’s also the most established product in the range, with close to one million patients treated using Select since its introduction, built on over two decades of product development.
The Select system is best suited for general alignment cases like crowding, spacing, and moderate bite corrections that don’t require the more specialised engineering of the Pro system.
Angel Aligner Pro: For Complex Cases
Where Select handles the everyday, Pro is engineered specifically for complex cases — the movements that need more precision, more control, and more anchorage than a standard aligner can reliably deliver.
What sets Pro apart is its dual-aligner “7+3” system. Rather than using one material throughout a stage, each stage of treatment uses two aligners in sequence:
- masterControl S (worn for 7 days): a softer material that initiates movement gently and prioritises patient comfort
- masterControl (worn for 3 days): a firmer material that adds precision and refines the movement
This staged approach to force delivery is designed to improve predictability in demanding cases without adding unnecessary complexity to the patient’s routine.
Pro is generally reserved for cases involving significant crowding or the kind of complexity where Select’s single-material approach isn’t enough on its own. Pro is also typically more expensive than Select since Pro is engineered for more complex cases requiring additional materials and technology.
Angel Aligner KiD: Built for Growing Patients
Angel Aligner KiD takes a different approach entirely. Adolescent patients often need guidance for how the jaw and bite develop. KiD is described as a three-in-one system: tooth alignment, myofunctional correction (addressing habits like tongue thrust or low tongue posture), and jaw growth guidance, combined into a single aligner-based approach.
Treatment is structured around two phases:
- Ages 6–12 (mixed dentition): treatment can include myofunctional appliances to address habits, A6 Mandibular Advancement to combine jaw guidance with tooth movement, space creation and maintenance for erupting permanent teeth, and support for guided eruption.
- Ages 12+ (transition to permanent dentition): treatment expands into a more comprehensive aligner approach, using tools like angelButton and eruption guides, digital arch-shaping planning, and continued use of A6 where a bite correction is still needed.

This phased structure means a child can, in principle, stay within the same product family from early mixed dentition right through to a fuller aligner-based treatment as their permanent teeth come through — rather than switching systems entirely partway through.
Angel Aligner Retainer: Holding the Result
Once active treatment finishes, the job shifts from moving teeth to keeping them in place. Angel Aligner Retainer is built specifically for that job.
It’s fabricated from a proprietary 1.0mm material engineered for durability and comfort during daily wear, with a light-diffusing, anti-reflective quality designed to keep it visually unobtrusive.
Retainers can be supplied for patients who completed treatment with Angel Aligner, or for patients coming from other treatment types entirely, including options to support fixed or lingual retainer workflows.
How the Four Systems Work Together
Most patients will only need Select, but the range is designed so an orthodontist can move between products as a case requires. Your orthodontist will assess your case and recommend the right product, or combination of products, as part of your treatment plan.
They will also advise if and when a change makes sense for your case. For example, transitioning a growing patient from KiD into further alignment as their permanent teeth come through. Which combination makes sense is a clinical decision made during your assessment, not a fixed pathway.
Why This Matters for Your Treatment
None of these products are interchangeable, and using the right one for your case is part of what a specialist orthodontist’s training is for. Choosing between Select and Pro, timing a transition through KiD’s two phases, or knowing when retention should begin all depend on an assessment of your specific bite, growth stage, and treatment goals. It’s never a one-size-fits-all recommendation.

The right product for your case depends on your teeth, your bite, and your goals — all things a specialist orthodontist will assess in person. Book a consultation to find out which Angel Aligner solution, if any, is the right fit for you.
