An underbite, also known as Class III malocclusion, is a dental issue where the lower teeth extend beyond the upper teeth, resulting in misalignment. Although not as common as other bite problems, underbites can seriously affect oral function, facial appearance, and overall self-esteem. Treatments typically involve orthodontic options like braces and specialized appliances, while severe cases may require orthognathic (jaw) surgery. Early intervention—especially in childhood—can reduce the need for future surgical procedures.
South Korea has become a top destination for medical tourism, particularly for dental and jaw correction. With high-quality facilities, experienced specialists, advanced technology, and competitive pricing, South Korea offers a comprehensive experience for patients worldwide. Costs are often lower than in the U.S., and many clinics provide all-in-one packages with support in multiple languages. Patient feedback strongly highlights improvements in chewing, speech, appearance, and confidence, further boosted by top-notch logistical and communication support.
Understanding Underbite (Class III Malocclusion)
Definition and Common Pseudonyms
An underbite is a specific kind of malocclusion characterized by the lower teeth overlapping the upper teeth when biting down. Severity can range from minimal to severe, with the lower jaw clearly protruding beyond the upper jaw. Underbites are the least common form of malocclusion.
Patients may encounter various clinical terms referring to underbite:
Table 1: Common Pseudonyms for Underbite
| Term | Description |
|---|---|
| Underbite | Lower teeth protrude past upper teeth when biting |
| Anterior Crossbite | Front lower teeth bite in front of upper teeth |
| Class III Malocclusion | Formal orthodontic classification for lower molars positioned too forward |
| Reverse-bite | Colloquial term for the inverted relationship of the bite |
| Mandibular Prognathism | Medical term for an excessively large or protrusive lower jaw |
Causes of Underbite
Most underbites are inherited, with a strong genetic link seen in affected families. Other contributing factors include jaw injury, oral tumors, childhood habits like thumb sucking, overcrowded teeth, or ill-fitting dental work. Importantly, underbites don’t self-correct—they can become more pronounced during growth spurts, especially around puberty. Starting treatment in childhood helps prevent worsening and reduces the likelihood of surgery, as studies show early correction can be stable in about two-thirds of cases.
Impact and Risks of Untreated Underbite
Untreated underbites can lead to significant health and function problems. Chewing can become difficult, sometimes resulting in malnutrition due to an inability to eat certain foods. Speech impediments and TMJ (jaw joint) pain are common, and misalignment can cause sleep issues like snoring or even sleep apnea. There’s also increased risk for tooth damage, gum disease, and oral infections due to uneven pressure and trouble cleaning crowded teeth. Aesthetically, underbites often cause a pronounced chin and concave profile, impacting self-confidence and leading to social challenges. These effects are often intertwined, with physical issues influencing psychological health. Correcting an underbite brings broad improvements in function, oral health, and emotional well-being.
Medical Procedures for Underbite Correction
Non-Surgical Orthodontic Interventions
Braces
Braces are common for mild to moderate Class III malocclusion, especially for younger patients:
- Metal Braces: Durable, cost-effective, but visible.
- Ceramic Braces: Tooth-colored for discretion, but pricier and require careful maintenance.
- Self-Ligating (Damon) Braces: Use a sliding mechanism, effective for severe crowding, and can improve facial aesthetics.
- Lingual Braces: Placed behind the teeth for invisibility; more expensive and may be less comfortable.
Braces use brackets and wires to slowly shift teeth and sometimes the jaw. Treatment typically lasts 18–36 months, with regular adjustments.
- Elastics: Used to move jaws by pulling the upper jaw forward.
- Mini-Implants: Provide stable anchor points for shifting teeth and jaw.
Clear Aligners (e.g., Invisalign)
Clear aligners are custom-made trays that gently shift teeth without wires or brackets. They’re discreet and popular among adults. Best for mild to moderate cases, aligners usually require about 12 months for results, and may be used along with elastics for more complex corrections.
Functional Appliances (for growing patients)
Early treatment (ages 7–8) is most effective:
- Reverse-Pull Headgear: Pulls the upper jaw forward, especially in children.
- Upper Jaw Expander: Gradually widens the upper jaw, worn for about a year.
Tooth Extraction
If overcrowding in the lower jaw contributes to the underbite, removing one or more teeth can create space for alignment.
Risks and Complications of Orthodontic Treatment
- Oral Hygiene Issues: Braces make cleaning harder, increasing the risk for cavities and gum disease.
- Soft Tissue Injuries: Sores from brackets and wires may occur but can be managed by an orthodontist.
- Allergic Reactions: Some may react to metals or latex; alternatives are available.
- Root Resorption: Usually minimal but rarely severe.
- Ankylosis: Rarely, a tooth fuses to the jawbone and cannot move with braces.
- Relapse: Teeth can shift back if retainers aren't worn as instructed.
Surgical Orthodontic Interventions (Orthognathic Surgery)
Orthognathic surgery (jaw surgery) is reserved for severe skeletal discrepancies:
- Le Fort I Osteotomy (Upper Jaw Surgery): Moves the upper jaw to improve bite and appearance.
- Bilateral Sagittal Split Osteotomy (BSSO - Lower Jaw Surgery): Adjusts the lower jaw.
- Double Jaw Surgery: Combines both for complex cases.
- Genioplasty: Realigns or reshapes the chin, can be standalone or combined.
Pre-Surgical Orthodontics
Pre-surgical braces or aligners (12–18 months) align teeth so they’ll fit together correctly after surgery. Surgery is generally performed after facial growth is complete.
Surgical Planning and Execution
The process involves consultations, scans, and digital planning, with the surgery itself performed under general anesthesia, using incisions inside the mouth to avoid visible scars.
Post-Surgical Recovery and Fine-Tuning
- First week: Swelling peaks then recedes; pain managed with medication; patients stick to a liquid diet.
- 1–3 weeks: Swelling and discomfort decrease, soft foods reintroduced, and healing monitored during follow-ups.
- 6+ months: Full function returns, and orthodontists refine tooth alignment.
Risks and Complications of Orthognathic Surgery
Possible risks include nerve trauma (numbness), jaw relapse, infection, changes in hearing, TMJ problems, anesthesia complications, need for revision surgery, and rare scarring or open bite development.
