PFM (Base Metal Alloy)

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).
