Quick answer: Angel Aligner and Invisalign are two brands of clear aligners. Both use a series of custom, removable clear trays planned from a 3D scan of your teeth, and both need to be worn about 20–22 hours a day. The main differences are the manufacturer, their own aligner materials and planning software, and price. At Trust Dental Surgery, clear aligner treatment uses Angel Aligner and starts from $2,800 before GST, including one set of retainers.
“Is Angel Aligner the same as Invisalign?” is one of the first questions patients ask when they see our clear aligner prices. It is a fair question: Invisalign is the clear aligner brand most people have heard of, and many people use the name for all clear aligners.
This guide explains what the two systems have in common, where they differ, and what actually makes the biggest difference to your result.
What Are Clear Aligners?
Clear aligners are thin, transparent trays made to fit your teeth. Each set is shaped slightly differently from the last, so wearing them one after another moves your teeth gradually towards a planned position. They are removable, so you take them out to eat and brush. “Clear aligners” is the type of treatment; Invisalign and Angel Aligner are two brands of it, in the same way that there are different brands of braces.
Who Makes Each System?
- Invisalign is made by Align Technology, a US company. It is a long-established clear aligner brand, and the one many people know by name.
- Angel Aligner (时代天使 in Chinese) is made by Angelalign Technology, a clear aligner company listed in Hong Kong. Its aligners are used by dentists and orthodontists in many countries, including Singapore.

What’s the Same
- How they work: a series of custom clear trays, each moving your teeth a small amount.
- How treatment is planned: your dentist takes a 3D scan of your teeth and plans the tooth movements digitally before any aligners are made.
- What it asks of you: wearing your aligners about 20–22 hours a day, taking them out only to eat, drink anything other than water, and brush.
- What comes after: retainers, to keep your teeth from drifting back.
Where They Differ
- Materials and software: each company makes its aligners from its own plastic material and uses its own treatment-planning software.
- Product range: each brand offers its own range of products for different types of cases. Your dentist chooses what suits your teeth.
- Price: fees differ between brands, partly because of what each manufacturer charges clinics to make the aligners.
What Matters More Than the Brand
For many patients, the things that make the biggest difference to how treatment goes are not about the logo on the box:
- Whether clear aligners suit your teeth. Mild to moderate crowding and gaps often respond well. Severe crowding or larger bite corrections may be better treated with braces. See our guide to clear aligners vs braces.
- How carefully treatment is planned and checked. Your dentist reviews the digital plan and checks your progress regularly.
- How consistently you wear them. Aligners only move teeth while they are in your mouth.
- Wearing your retainers afterwards. This is what keeps your result.
