PFM Restoration

PFM (Porcelain Fused to Metal) is a classic type of dental restoration that combines a metal substructure with a porcelain outer layer, merging the strength of metal with the natural aesthetics of porcelain. This proven solution has been widely used for decades and is suitable for both single crowns and long-span bridges.

Benefits and Material Evaluation

• High durability: The internal metal framework provides excellent strength, making PFM ideal for posterior restorations, long-span bridges, or patients with strong bite forces.

• Natural aesthetics: The outer porcelain layer is shaped and color-matched to mimic natural teeth, ensuring basic aesthetic appeal.

• Cost-effective: A more economical option compared to zirconia or all-ceramic restorations, while still offering reliable functionality and long-term durability.

Technical Specifications

• Structure: Metal framework (Ni-Cr, Co-Cr, or noble alloys) + porcelain layering.

• Minimum thickness: 1.0 mm – 2.0 mm (depending on clinical location and indication).

• Flexural strength: Over 1000 MPa (depending on the type of metal alloy used).

• Applications: Single crowns, long-span bridges, implant-supported restorations.

• In-lab working time: 2~3 days in lab (*digital file).
