Selection Criteria Explained by a Dental Specialist

• Average 18 Months for Clear Aligners
• 1.5-2 Times the Cost of Conventional Orthodontics
• Laminates Completed in 2 Weeks

“Isn’t clear aligners enough for everything?” — This question determines 30% of the results

This is the most common misconception heard in the clinic. “Since clear aligners are the latest technology, they must naturally be better, right?” To start with the conclusion, clear aligners are a system optimized for **mild to moderate malocclusion**. For cases involving skeletal malocclusion or tooth extraction, conventional orthodontics may be more effective. According to a 2022 presentation by the Korean Association of Orthodontists, clear aligners are indicated for approximately 60-70% of all orthodontic cases. For the remaining 30-40%, metal brackets or lingual braces yield more accurate results. In particular, when there is severe skeletal imbalance between the upper and lower jaws, it is difficult to adjust the occlusion using clear aligners alone. Conversely, there are many cases where people say, "If I get veneers, it's done in two weeks." However, veneers are a **prosthetic procedure**, not orthodontics. By removing 0.3-0.7mm of tooth structure and attaching a ceramic shell, it does not resolve occlusal issues. It is for simple aesthetic improvement. In this article, we will completely break down the three types of orthodontics—**clear aligners (Invisalign, Clearline, etc.), conventional braces (metal, ceramic, Clippy-C), and veneers—in terms of cost, duration, indications, and pros and cons. Find the option that suits your case. Key Point: The orthodontic method is determined by the **occlusion condition**, not by 'trends.' If you choose without a precise diagnosis by a specialist, the retreatment rate increases by more than double. Clear Aligners — The #1 choice for office workers who want to eat without braces The representative brand of clear aligners is **Invisalign (FDA approved in 1997)**. While there are local brands in Korea such as Clearline and A-Line, Invisalign stands out in terms of clinical data and algorithmic sophistication. Invisalign possesses data from 14 million cases worldwide, resulting in high predictive accuracy. The average treatment period is **12–24 months**. Mild anterior alignment takes 6–12 months, while moderate malocclusion takes over 18 months. The principle is to wear them for 20–22 hours a day, and new braces are replaced every two weeks. The biggest advantage is that they can be removed for meals and brushing. The cost is in the **4–8 million won** range. The Invisalign Full package costs 7–8 million won, and the Light package (for mild cases) costs 4–5 million won. It is 1.5 to 2 times more expensive than conventional orthodontics. However, the long visit interval of 6-8 weeks is advantageous for busy office workers. The disadvantage is that the results depend on **patient cooperation**. If the wearing schedule is not adhered to, tooth movement will not proceed as planned. Additionally, accuracy decreases in extraction cases or for teeth requiring significant rotation. In such cases, mini brackets may be attached as an auxiliary measure. Tip: If you feel that the corrective force is insufficient during clear aligner treatment, the number of 'attachments' is important. Resin protrusions attached to the surface of the teeth; the more protrusions there are, the more complex tooth movement is possible.

• Invisalign full package average 7 million won
• Wearing time 20-22 hours per day is mandatory
• Visit frequency 6-8 weeks

Traditional Orthodontics — For complex malocclusion, 'Metal' is still the answer

Traditional orthodontics is broadly divided into **metal brackets, ceramic brackets, Clippy-C (self-ligating), and lingual orthodontics**. Metal is the most affordable (2.5-4 million won), and ceramic is a version that complements aesthetics (3.5-5 million won). Clippy-C features a wire fixing device built into the bracket, resulting in less friction and faster movement speeds (4-6 million KRW). Lingual orthodontics attaches brackets to the inside of the teeth, making them invisible from the outside. It is the most expensive, costing **8-12 million KRW**, and discomfort with pronunciation and tongue contact persists for the first 2-3 weeks. However, the corrective force is the same as labial (outer) orthodontics. The average treatment period is **18-30 months**. Cases involving tooth extraction or skeletal malocclusion require more than 30 months. The frequency of visits is 3-4 weeks, which is shorter than clear aligners. Pain may occur for 2-3 days each time the wire is adjusted. The greatest advantage of conventional orthodontics is the precision of **3D movement control**. Tooth rotation, extrusion (pulling down), and intrusion (pushing in) are all possible. In the 2019 Journal of Clinical Orthodontics study, conventional orthodontics had a 15% higher success rate compared to clear aligners for complex occlusal adjustments. Clinical space closure after tooth extraction is on average 4-6 months faster with conventional orthodontics. Clear aligners control the speed because the risk of root resorption is relatively high during large tooth movements.

Laminates — The trap of “2-week completion,” not orthodontics It is a 'prosthetic'. Laminates are a procedure in which the front surface of the tooth is **removed by 0.3-0.7mm** and a ceramic shell is attached. Unlike orthodontics, the teeth are not actually moved; instead, the alignment is corrected by 'covering' them. While color, shape, and slight alignment improvements are possible, **the occlusion (bite) cannot be changed**. The cost is **800,000 to 1,500,000 KRW per tooth**. Doing six front teeth costs 4,800,000 to 9,000,000 KRW, which is similar to or more expensive than clear aligners. The procedure is completed within two weeks with 2-3 visits. The effects are immediate, but since the tooth roots do not move like with orthodontics, occlusal imbalance may occur in the long term. **The removal of tooth structure with laminates is irreversible**. Once the tooth is trimmed, it cannot be restored, and if the ceramic detaches or breaks, a re-procedure is required. The average lifespan is 7–15 years, but it varies significantly depending on maintenance. Indications are the **restoration of minor misalignment, discoloration, or worn teeth**. It cannot resolve skeletal issues such as protrusion or an underbite. Additionally, if teeth overlap or rotate significantly, a large amount of tooth reduction is required, posing a risk of nerve damage. In such cases, veneers are recommended after orthodontic treatment. Caution: Beware of advertisements claiming "straighten in just 2 weeks without orthodontics." Laminates do not resolve occlusal problems, and improper procedures can cause temporomandibular joint disorders.

• 800,000–1,500,000 KRW per tooth
• Tooth reduction amount 0.3–0.7 mm
• Average lifespan 7–15 years

Why You Shouldn't Look Only at Cost and Duration — Optimal Selection by Case

**College students in their 20s, minor anterior misalignment**: Clear aligners (Light) or partial orthodontics are suitable. Duration 6–12 months, cost 3–5,000,000 KRW. It is aesthetically pleasing with minimal visits. However, the occlusion must be stable, and if molar correction is required, you must switch to the full package.

**Office workers in their 30s, protruding mouth + need for extraction**: Conventional orthodontics (metal or ceramic) is the top priority. Conventional orthodontics closes extraction spaces 4-6 months faster and offers precise control over anterior-posterior movement. Duration: 24-30 months, Cost: 3.5-5 million KRW. Choose metal if wearing a mask at work is permitted, or ceramic if aesthetics are important. **Self-employed in their 40s, discoloration + mild misalignment**: Laminates or all-ceramic crowns are suitable after orthodontics. The occlusion is aligned first through orthodontics (12-18 months), and then color and shape are improved with prosthetics. Total cost: 8-15 million KRW. Relying solely on laminates may lead to temporomandibular joint (TMJ) problems due to occlusal imbalance. **Teenagers, skeletal malocclusion**: If the patient is in the growth phase, functional orthodontic devices (headgear, face mask) must be used in conjunction. Clear aligners are not recommended due to the difficulty in controlling growth. After proceeding with conventional orthodontics for 2-3 years, the decision regarding jaw surgery is made at the time growth is complete. Key Point: Comparing costs is meaningless if you do not know your bite type. Get an accurate diagnosis through a 1:1 consultation with an orthodontist at K-Dia. You can reduce the retreatment rate by half. 3 Selection Criteria You Must Not Miss **1. Extraction Requirement**: Conventional orthodontics is significantly more advantageous in cases requiring extraction. Clear aligners carry a relatively higher risk of root resorption when closing large spaces. In a 2020 study in the American Journal of Orthodontics, the success rate for space closure after extraction was 92% for conventional orthodontics and 79% for clear aligners. **2. Patient Compliance**: Wearing clear aligners for more than 20 hours a day is mandatory. Conventional orthodontics is safer for teenagers who have difficulty managing their own health, or for office workers who frequently attend company dinners. Conversely, clear aligners are suitable for those in their 30s and 40s who have many meetings and for whom aesthetics are important. **3. Balance of Budget and Duration**: Laminates are fast, taking only two weeks, but they cannot resolve occlusal issues. Conventional orthodontics takes 24 to 30 months, but it can address all types of malocclusion. Clear aligners fall in the middle, and can be completed within 18 months for mild to moderate cases. According to the 2023 guidelines of the Korean Association of Orthodontists, **cephalometry** and 3D CT scans are mandatory before orthodontic treatment. Starting without knowing your skeletal pattern increases the retreatment rate by 2.5 times. Please get a precise diagnosis even if it costs an extra 100,000 won. **Tip** Check your insurance before orthodontic treatment. Orthodontic treatment is not covered by national health insurance, but some private health insurance plans partially cover pre-surgical orthodontic costs upon diagnosis of 'maxillofacial deformity'. Carefully check the insurance company's terms and conditions.

• Success rate of conventional orthodontics for extraction cases: 92%
• Success rate of clear aligners for extraction cases: 79%
• Additional cost of 1.5-3 million KRW for retreatment

Clear Aligners vs. Conventional Aligners vs. Laminates at a Glance

Common misconceptions

Must check before starting orthodontic treatment

• Do not start without cephalometry — Retreatment rate 2.5 times higher if skeletal pattern is unknown
• Beware of exaggerated claims of “finished in one year” — Risk of root resorption if complex cases are rushed too much
• Tooth movement delayed if wearing time is less than 20 hours during clear aligners — Duration may increase by more than 6 months
• Occlusal evaluation is essential before veneers — Procedures performed in an unstable occlusal state may cause temporomandibular joint disorder
• Beware of low-cost clear aligner brands — Insufficient clinical data leads to larger prediction errors and higher retreatment rates
