Leading the trend in modern orthodontics, clear aligners are increasingly preferred by many patients thanks to their high aesthetic value and comfortable wearing experience. This orthodontic method uses transparent aligner trays to gradually move teeth into the desired position while remaining nearly invisible during daily communication.
Not only do clear aligners help correct misaligned teeth and bite issues, but they also allow patients to maintain confidence throughout the treatment process. In the article below, the professional team at Smilux Dental will help you explore the key information about clear aligners, including their advantages, cost, and treatment procedure.

Clear aligners (also known as transparent aligners, clear trays, or aligner-based orthodontics) are an orthodontic treatment method that uses a series of transparent trays made from medical-grade biocompatible plastic. These aligners fit closely over the teeth and apply gentle, controlled pressure to gradually move them into their desired positions.
Each aligner is custom-designed based on the patient’s dental condition and the level of misalignment. Using digital scans and a personalized treatment plan created by the specialists at Smilux Dental, the aligner system guides tooth movement in carefully planned stages.
In most cases, a clear aligner treatment requires around 20 to 40 aligners or more, depending on the complexity of the case. Patients typically switch to a new aligner every 1 to 2 weeks, allowing the teeth to continue moving progressively according to the planned treatment sequence.
Both traditional metal braces and Invisalign clear aligners are effective in moving teeth into their proper positions on the dental arch. However, clear aligners are increasingly preferred by many patients due to several outstanding advantages, including:
Clear aligners are made from transparent medical-grade plastic, making them barely noticeable when worn. This allows patients to communicate confidently, meet clients, or attend social events without worrying about visible orthodontic appliances.
In addition to their aesthetic advantage, clear aligners also help reduce the risk of tooth staining often associated with brackets. Since there are no metal brackets or colored elastics attached to the teeth, the smile appears more natural throughout the orthodontic treatment process.
Clear aligners can be easily removed during meals, allowing patients to eat comfortably without worrying about food getting trapped in orthodontic appliances, which is common with traditional metal braces. This flexibility makes daily eating habits much more convenient.
After meals, patients can brush their teeth and use dental floss as usual before placing the aligners back on. This helps maintain good oral hygiene and reduces the risk of tooth decay and gum inflammation throughout the orthodontic treatment.
Clear aligners do not use metal brackets or archwires, which helps minimize the discomfort and irritation commonly associated with traditional braces. With their smooth design and snug fit over the teeth, patients can speak and chew more comfortably during treatment.
Each aligner is designed to move teeth gradually, typically about 0.25 to 0.33 mm per stage, allowing controlled and gentle tooth movement. This controlled force helps reduce pain and discomfort throughout the orthodontic process.
Clear aligners help guide teeth into their proper positions on the dental arch, improving misalignment and creating a straighter, more balanced smile. With digital treatment planning and simulation technology, orthodontists can accurately control each stage of tooth movement throughout the treatment process.
In suitable cases, this method may even deliver more precise and predictable results compared to traditional fixed braces.
Patients using clear aligners typically need follow up appointments every 6 to 8 weeks, which helps reduce the time and travel costs associated with frequent dental visits during orthodontic treatment.
At Smilux Dental, patients are often provided with 2 to 4 sets of aligners at a time, allowing them to change the trays at home according to the prescribed treatment schedule. They only need to return to the clinic for scheduled checkups or if any issue requires professional evaluation.
Thanks to this flexibility, clear aligners are especially suitable for patients with busy schedules, those who frequently travel for work, or individuals studying or living abroad.
Most patients can undergo treatment with clear aligners. This orthodontic method is particularly suitable for the following cases:
| Cost: 60,000,000 – 150,000,000 VND for both arches | |||
| Level 1 (Mild Misalignment): 60 – 90 million VND | |||
| Level 2 (Moderate misalignment – moderate crowding): 90 – 120 million VND | |||
| Level 3 (Complex cases – severe bite misalignment, overbite or underbite): 120 – 150 million VND |

At Smilux Dental, clear aligner treatment integrates advanced digital technology with a standardized medical protocol to ensure a safe, effective, and high quality orthodontic experience.
The treatment process typically includes the following steps:
The orthodontist performs a comprehensive oral examination and takes diagnostic images to evaluate the jawbone structure, tooth root positions, and any dental conditions that may need to be addressed before orthodontic treatment. Based on the examination results, the doctor will recommend the most suitable clear aligner treatment plan.
Patients undergo a digital scan using the iTero 3D scanner, which captures precise dental impressions quickly and comfortably. This technology replaces traditional dental molds and provides accurate digital data for orthodontic planning.
Using the 3D scan data, the orthodontist develops a customized tooth movement plan through ClinCheck software. Patients can preview a simulation of their expected results and understand the entire treatment journey before starting.
Each aligner set is custom designed for the patient and manufactured at specialized production centers abroad. Once completed, the aligners are delivered to the clinic to begin the treatment process.
The orthodontist will guide patients on how to wear, remove, and properly clean the aligners. In some cases, small tooth colored attachments may be bonded to the teeth to help control tooth movement and improve treatment precision.
Patients typically return for follow up appointments every 6 to 8 weeks. During these visits, the orthodontist evaluates tooth movement progress and provides the next set of aligners according to the treatment plan.
Once the teeth reach their desired positions, patients will be instructed to wear retainers. Retainers help maintain the new alignment and stabilize the bite, preventing teeth from shifting back after orthodontic treatment.
Clear aligner orthodontics is considered one of the most advanced orthodontic technologies available today. However, not every dental clinic is qualified or licensed to provide this treatment. Successful clear aligner therapy requires experienced orthodontists, modern equipment, and advanced technologies that support precise treatment planning.
At Smilux International Dental Clinic (Phu Nhuan, Ho Chi Minh City), patients can feel confident when choosing clear aligner treatment. The clinic meets strict professional standards, including licensed operations, highly experienced orthodontists, and a modern dental facility. In addition, Smilux Dental pioneers the application of advanced orthodontic technologies that enhance treatment comfort and safety for patients.
One of the key technologies used at Smilux is BioLight, which works through a biological light activation mechanism. This technology helps stimulate bone and surrounding tissue regeneration during orthodontic treatment. As a result, teeth can move more predictably according to the treatment plan, while reducing the discomfort that may occur when switching aligners or applying orthodontic force.
