Porcelain inlays and onlays are high-quality dental restorations used to repair moderate-to-large cavities or replace old, failing fillings. They offer superior aesthetics and strength compared to traditional fillings and are custom-made to fit each patient’s tooth precisely. In Korea, porcelain restorations are widely offered at dental clinics known for advanced technology and cosmetic dentistry expertise.



What Are Porcelain Inlays and Onlays?

Porcelain Inlays are custom ceramic restorations that fit within the cusps (top edges) of a tooth. They are ideal when decay or damage does not require full coverage.

Porcelain Onlays, on the other hand, cover one or more cusps and may extend over the biting surface. Onlays are used when more structural support is needed but a full crown is not necessary.

Both inlays and onlays are fabricated in a dental laboratory after precise impressions or digital scans. They are bonded to the tooth with strong adhesive materials, creating a durable and natural-looking restoration.

Average Cost Range in Korea

The cost of porcelain inlays and onlays in Korea varies based on the clinic, material type, and complexity of the restoration. Typical price ranges are as follows:

₩500,000 to ₩1,800,000 per tooth

The range reflects factors such as:

• Type of ceramic used: Standard porcelain vs. high-strength ceramic (e.g., zirconia-based)
• Inlay vs Onlay: Onlays generally cost more than inlays due to larger coverage
• Clinic reputation and technology: Premium clinics with digital workflows may charge higher fees
• Dentist expertise and lab fees: Custom fabrication and specialist involvement affect pricing

Actual treatment costs can differ by clinic and patient case.

What Influences the Price?

Several factors contribute to the total cost of porcelain inlay and onlay restorations:

• Material Quality: High-strength ceramics and advanced materials increase cost.
• Digital Design and Fabrication: Use of CAD/CAM technology provides better fit and aesthetics but may add to fees.
• Number of Surfaces Covered: Larger restorations covering more surfaces require more material and time.
• Lab Fees: Ceramic restorations require skilled dental laboratory work, which is a significant part of the cost.
• Additional Procedures: If core buildup, temporary restoration, or root canal therapy is needed, the price may increase.

Insurance Coverage in Korea

Porcelain inlays and onlays are usually classified as premium cosmetic-restorative treatments. For this reason, they are not covered by Korean National Health Insurance in most cases. Patients typically pay the full cost out of pocket.

Only in rare clinical circumstances where functional needs are documented might partial coverage be possible, depending on insurance terms.

Patients should confirm coverage details with both their dentist and insurer before treatment.

Porcelain Inlays/Onlays vs Other Options

• Composite Fillings:
• Lower cost
• Good for small cavities
• Less durable for large restorations
• Amalgam (Silver) Fillings:
• Lowest cost
• Durable but less aesthetic
• Ceramic Inlays/Onlays:
• Excellent aesthetics, natural appearance
• Higher cost and laboratory fabrication
• Porcelain Crowns:
• Full coverage solution
• Higher cost and more tooth reduction

Porcelain inlays and onlays strike a balance between aesthetics, strength, and conservation of tooth structure, making them ideal for moderate defects.

Longevity and Durability

Porcelain inlays and onlays are known for longevity and wear resistance. With proper oral hygiene and regular dental checkups, they can last many years. Compared with direct resin fillings, porcelain restorations resist staining, maintain shape, and provide strong functional support, especially on back teeth.

Why Patients Choose Porcelain Inlays and Onlays in Korea

Korea is recognized for its high standards in cosmetic and restorative dentistry. Many clinics offer:

• Advanced digital scanning and design
• CAD/CAM fabrication for precision fit
• In-depth aesthetic planning
• Transparent cost breakdowns

These factors attract both local and international patients seeking natural-looking, long-lasting restorations.

Conclusion

Porcelain inlay and onlay costs in Korea generally range from ₩500,000 to ₩1,800,000 per tooth. Prices vary depending on material quality, restoration size, clinic standards, and other clinical needs. These restorations offer a highly aesthetic and durable alternative to traditional fillings, ideal for patients seeking both function and appearance. For accurate pricing and treatment recommendations, it is best to consult directly with a qualified dental professional.
