Aligners (Orthodontic Trays) - Bite Correction Without Braces

Aligners are modern orthodontic appliances used to gradually straighten teeth and correct bite irregularities. They are transparent, removable trays that serve as an alternative to traditional braces.

Each aligner is custom-made from medical-grade thermoplastic material based on the patient’s individual treatment plan. The trays are thin, transparent, and virtually invisible when worn, allowing patients to undergo orthodontic treatment without affecting the appearance of their smile. At the same time, the material is durable enough to create gentle, controlled pressure that gradually moves the teeth into the desired position.

One of the main advantages of aligners is their removability. Unlike braces, aligners can be taken out while eating and during oral hygiene procedures, making daily care more comfortable and convenient. They may also be removed for important meetings or special occasions if necessary. However, to achieve effective and predictable results, aligners should be worn for approximately 22 hours per day. Failure to follow this recommendation may prolong treatment time and affect the final outcome.

How do aligners work? Treatment involves a series of custom-made trays rather than just one pair. Depending on the complexity of the case, the patient may receive anywhere from 15 to 50 or more sets of aligners. Each set is numbered and designed for a specific stage of tooth movement.

Typically, one pair of aligners is worn for about two weeks before being replaced with the next set in the sequence. Each new aligner moves the teeth by only fractions of a millimeter, allowing for gradual, precise, and carefully controlled correction of tooth position and bite alignment.

Factors affecting the cost of aligner treatment:

1. Complexity of the clinical case. One of the primary factors influencing the cost of treatment is the severity of the bite irregularity and tooth misalignment. More complex orthodontic cases require longer treatment duration, more detailed planning, and a greater number of aligners, which directly affects the final cost.
2. Number of aligners required. The number of aligners is closely related to the complexity of the case. Comprehensive bite correction often involves multiple stages of tooth movement and may require more than 50 pairs of aligners. In contrast, minor orthodontic concerns — such as a small gap between teeth or mild crowding — may require only 10–15 sets. As a result, the cost of treatment can vary significantly depending on the scope of correction needed.
3. Aligner system brand. Different aligner systems vary in terms of technology, clinical research, treatment capabilities, and manufacturing standards. One of the most recognized systems worldwide is Invisalign by Align Technology (USA), considered the gold standard in aligner orthodontics due to its extensive clinical experience and strong evidence-based track record. Another high-quality option is the Angel aligner system, which combines advanced digital treatment planning with predictable clinical outcomes while offering a more accessible price point. ArtLine aligners belong to the more budget-friendly segment and can also provide effective orthodontic correction depending on the individual clinical situation and treatment objectives.
4. Materials and manufacturing quality. The quality of materials and production technologies also plays an important role in treatment cost. Leading manufacturers use advanced multilayer thermoplastic materials that combine strength, flexibility, comfort, and aesthetics. Modern digital manufacturing and precision printing technologies further enhance treatment accuracy and predictability, while also increasing production costs.
5. Additional factors. The total cost of aligner treatment may also include additional diagnostic procedures, such as CBCT imaging, digital scans, and functional analysis, as well as the use of auxiliary orthodontic elements, including temporary anchorage devices (micro-implants), when required for more complex tooth movements.
