Metal Porcelain Crown

What is a Metal Porcelain Crown?
A metal porcelain crown, also known as a porcelain-fused-to-metal crown or PFM crown, is a type of dental crown used to restore damaged or decayed teeth. It is made by fusing a thin layer of porcelain to a metal base, usually made of gold, silver, or another alloy. The metal provides strength and durability, while the porcelain gives the crown a natural and aesthetically pleasing appearance.

Advantages of Metal Porcelain Crowns
1. Strength and Durability: The metal base of a metal porcelain crown provides excellent strength, making it suitable for restoring heavily damaged or decayed teeth. It can withstand the forces of biting and chewing without breaking or fracturing.

2. Aesthetics: The porcelain layer on top of the metal base allows the crown to blend seamlessly with the natural teeth. The color of the porcelain can be matched to the surrounding teeth, ensuring a natural-looking smile.

3. Longevity: Metal porcelain crowns have a long lifespan. With proper care and maintenance, they can last for many years, providing a durable and reliable solution for tooth restoration.

4. Resistance to Wear: The metal base of the crown is highly resistant to wear and tear. This makes metal porcelain crowns an excellent choice for patients who grind or clench their teeth.

Disadvantages of Metal Porcelain Crowns
1. Aesthetics: While metal porcelain crowns provide good aesthetics, they may not be as visually appealing as all-porcelain crowns. The metal layer beneath the porcelain may create a slight grayish hue, especially in areas where the gumline is receded.

2. Allergy Potential: Some individuals may have allergies or sensitivities to the metals used in metal porcelain crowns. It is essential to inform your dentist about any known allergies to ensure the appropriate choice of materials.

3. Wear on Opposing Teeth: The metal portion of the crown may cause slight wear on the opposing teeth, particularly if there is a significant difference in hardness between the crown and the natural tooth structure.

4. Potential for Fracture: Although metal porcelain crowns are generally durable, there is a possibility of porcelain chipping or fracturing over time, especially if the underlying metal becomes exposed due to gum recession or other factors.

The Procedure of Placing a Metal Porcelain Crown

1. Tooth Preparation
To prepare the tooth for a metal porcelain crown, the dentist will first numb the area with a local anesthetic. Then, the dentist will remove any decayed or damaged portions of the tooth to create space for the crown. The tooth will be shaped and reshaped to ensure a proper fit for the crown.

2. Impression
After the tooth is prepared, the dentist will take an impression of the tooth and the surrounding teeth. This impression will be sent to a dental laboratory, where the metal porcelain crown will be custom-made.

3. Temporary Crown Placement
While waiting for the permanent crown to be fabricated, the dentist will place a temporary crown over the prepared tooth. This temporary crown protects the tooth and maintains its appearance and function until the final crown is ready.

4. Crown Placement
Once the permanent crown is received from the dental laboratory, the temporary crown will be removed. The dentist will carefully check the fit and appearance of the metal porcelain crown. Any necessary adjustments will be made before permanently cementing the crown onto the tooth.

5. Follow-up
After crown placement, the dentist will provide instructions on how to care for the crown properly. Regular dental check-ups and good oral hygiene practices, such as brushing and flossing, are essential to maintain the longevity of the crown.

Conclusion
Metal porcelain crowns are a popular choice for dental restorations due to their strength, durability, and natural appearance. With the advancement of dental technology, these crowns have become an excellent option for patients seeking long-lasting and aesthetically pleasing solutions for damaged or decayed teeth. However, it is crucial to consult with a dentist to determine the most suitable crown material based on individual needs and preferences.
