What are invisible aligners? Difference between invisible aligners and Invisalign.

Many people believe that Invisalign is different from clear aligner orthodontics, but in fact, Invisalign is a well-known brand of clear aligner treatment, also known as invisible braces or aligner-based orthodontics.

What is clear aligner orthodontics?

Clear aligner orthodontics, also known as invisible braces, is the most advanced method of teeth straightening today. This technique uses AI technology to scan the teeth, analyze data, and design a personalized treatment plan for tooth movement. Based on this, transparent plastic aligners are custom-made and 3D-printed for each patient and each treatment phase. These aligners fit snugly over the teeth, applying gentle pressure to move them into the desired position, improving both dental function and aesthetics.

Distinguishing Clear Aligners from Invisalign

Invisalign là một hãng niềng khay trong suốt số 1 hiện nay. Được phát triển bởi tập đoàn Align Technology, Mỹ từ năm 1999 đến nay, Invisalign hiện có khoảng hơn 10 triệu khách hàng đã và đang điều trị trên toàn cầu. Với lượng khách hàng lớn, cơ sở dữ liệu khổng lồ, cùng sự phát triển của công nghệ AI, thì Invisalign vẫn là lựa chọn hàng đầu của khách hàng khi lựa chọn phương pháp niềng răng trong suốt.

However, there are now several other clear aligner brands on the market such as Lee Tray, Vinalign, 3D Clear, and eCligner. These brands offer competitive technology, quality, and pricing, making modern orthodontic solutions more accessible while still delivering effective results.

Cases Suitable for Clear Aligner Treatment

Thanks to advancements in technology, clear aligners are no longer limited to minor misalignments. They can now address a wide range of dental conditions, including:

• Crowded or widely spaced teeth
• Protruding (buck) teeth
• Underbites and crossbites
• Some cases that require tooth extraction to improve bite alignment

Moreover, clear aligner treatment is suitable for a wide range of ages, from children to adults. It is especially ideal for busy individuals who don't have time for frequent dental visits, those who engage in regular public interactions, and people who require high aesthetic standards.

Advantages and Limitations of Clear Aligner Braces

Advantages

• Clear aligner treatment is a modern orthodontic solution that allows patients to preview their treatment plan, including the movement and changes of their teeth before, during, and after treatment. This helps patients better understand the method and track their own progress.
• One of the biggest advantages of clear aligners is their high level of aesthetics. They are virtually invisible when worn, making them suitable for people of all ages and professions. This helps users feel confident in communication and daily life, overcoming feelings of insecurity or self-consciousness.

• With clear aligners, patients find it easier to maintain oral hygiene, saving time and minimizing issues such as food getting stuck, which can lead to gum inflammation, tartar buildup, cavities, and bad breath.
• Clear aligners are also user-friendly, allowing for convenient removal and reinsertion. The smooth, high-quality transparent trays are non-irritating and help avoid discomfort, scraping, or poking of the inner cheeks and tongue—issues commonly associated with traditional braces.

Disadvantages

• Higher cost: Invisalign tends to be more expensive than traditional braces, making it less accessible for some patients.
• Requires discipline: Since aligners are removable, treatment success depends on patient compliance — wearing them 20–22 hours/day. Lost or broken trays can increase costs and delay progress.
• Not suitable for all cases: Some conditions may still require traditional braces. An in-person consultation with a qualified provider is essential to determine eligibility.

How long does clear aligner treatment take? Is it effective?

The duration of clear aligner treatment depends on the degree of dental misalignment for each patient. For simple cases, treatment may last from 9 to 18 months, while more complex cases that require a larger number of aligners can take 18 to 32 months.

However, studies have shown that clear aligner treatment may take 3–6 months longer compared to similar cases using traditional braces.

Cost of clear aligner treatment

The cost of clear aligners depends on the number of aligners needed and the brand chosen. Typically, the cost ranges from VND 60 to 120 million.
