PFM Dental Crowns & Bridges


Non precious PFM Crowns

Non-precious PFM (Porcelain Fused to Metal) is a type of dental crown that combines a metal substructure with a porcelain outer layer. In contrast to precious metal PFM crowns, non-precious PFM crowns utilize non-precious metals such as nickel-chrome or cobalt-chrome. The metal substructure provides strength and stability,. Non-precious PFM crowns are widely used due to their cost-effectiveness. However, it's important to note that some individuals may have allergies to non-precious metal materials.


Semi-precious PFM Crowns

Semi-precious PFM (Porcelain-Fused-to-Metal) crowns combine a metal substructure with a porcelain exterior. Unlike non-precious PFM crowns, which use non-precious metals, semi-precious PFM crowns utilize higher-value metals like silver or other semi-precious metals. They offer both durability and aesthetic appeal, striking a balance between cost-effectiveness and a natural-looking smile. With enhanced biocompatibility and reduced risk of allergic reactions, semi-precious PFM crowns are a popular choice in restorative dentistry. Their superior strength and aesthetics make them a reliable option for patients seeking long-lasting dental restorations.

High Noble

High Noble PFM Crowns

High Noble PFM (Porcelain-Fused-to-Metal) crowns combine a metal substructure with a porcelain outer layer. They use metals with a high noble metal content like gold, platinum, or palladium. These metals offer excellent biocompatibility, durability, and resistance to corrosion. The metal substructure provides strength, while the porcelain layer ensures natural aesthetics. High Noble PFM crowns are known for their superior fit, biocompatibility, and resistance to tarnish or discoloration. They are chosen for their high quality, longevity, and aesthetic results.

Porcelain Fused to Metal Crowns(PFM Crowns & Bridges) FAQ

Porcelain Fused to Metal (PFM) Introduction

Porcelain Fused to Metal (PFM) is a popular dental restoration technique that combines the strength and durability of metal with the aesthetic benefits of porcelain. It is commonly used for dental crowns and fixed bridges, providing both functional and aesthetic improvements to the patient's smile.

Porcelain Fused to Metal(PFM) Classification

PFM restorations can be categorized based on the composition of the metal alloy used within the framework. The three main types of PFM classifications are:

Non-Precious PFM: These restorations use non-precious metals like cobalt-chromium or nickel-chromium alloys. They are cost-effective options that offer adequate strength and durability.
Semi-Precious PFM: These restorations use alloys containing a moderate amount of precious metal, such as silver and palladium. They provide enhanced biocompatibility and corrosion resistance over non-precious PFM restorations.
High Noble PFM: These restorations use alloys containing a higher percentage of precious metals, such as gold and platinum. They offer excellent biocompatibility, corrosion resistance, and longevity, making them ideal for patients with specific needs or sensitivities.


Strength and Stability: PFM restorations are durable and can withstand normal biting forces, providing long-lasting results.
Aesthetics: The porcelain layer on the PFM restoration can be customized to match the color, translucency, and texture of the patient's natural teeth, resulting in a natural and esthetically pleasing appearance.
Versatility: PFM restorations can be used in various clinical situations, including single crowns and dental bridges, making them a versatile option for restorative dentistry.
Longevity: With proper oral hygiene and regular dental check-ups, PFM restorations can last for many years, providing reliable and functional dental restorations.

Potentially Visible Metal: Depending on the gumline and tissue recession, the metal framework beneath the porcelain may become visible, affecting the esthetics of the restoration.
Wear on Opposing Teeth: The hardness of the metal substructure in PFM restorations may cause accelerated wear on the natural teeth or opposing dental restorations.
Allergic Reactions: Although rare, some individuals may develop allergic reactions to the metals used in PFM restorations, especially with non-precious alloys. Patients should inform their dentist about any known metal allergies.


Regular Dental Check-ups: Routine dental examinations and professional cleanings are crucial for monitoring the condition of PFM restorations and identifying any potential issues at an early stage.
Oral Hygiene Maintenance: Good oral hygiene practices, including regular brushing, flossing, and the use of antimicrobial mouthwash, help maintain the health and longevity of PFM restorations.
Avoid Excessive Forces: Patients should avoid biting or chewing on hard objects or engaging in habits like nail-biting, as excessive forces can potentially damage the PFM restorations.
