The Effect Of Material Selection On Dental Crown Durability

I. Introduction

Dental crowns are a widely used dental solution for repairing teeth that are damaged or decayed. They involve placing a cap over a tooth to enhance its strength, shape, and aesthetic appeal. The selection of materials for dental crowns is vital to their durability. This blog aims to examine the various materials utilized in dental crowns and explore how the choice of material affects their longevity. Additionally, we will highlight the significance of selecting a reputable dental lab to ensure optimal outcomes for your dental crown.

II. Types of Materials Used for Dental Crowns

There are four main types of materials used for dental crowns, each with their unique properties and advantages.

A. Porcelain/Ceramic Crowns

Porcelain or ceramic crowns are the most popular choice for dental crowns due to their natural appearance, biocompatibility, and durability. They are often used for front teeth and are color-matched to blend seamlessly with the surrounding teeth.

B. Metal Crowns

Metal crowns are strong and durable but are not as aesthetically pleasing as porcelain/ceramic crowns. They are often used for molars and teeth that are not visible when smiling.

C. Porcelain-fused-to-metal (PFM) Crowns

PFM crowns is made by combining the strength of metal with the natural appearance of porcelain/ceramic. However, over time, the porcelain can chip, revealing the metal underneath, affecting the appearance.

D. Zirconia Crowns

Zirconia crowns are relatively new to the market and are popular due to their strength and durability. They are often used for molars and are less likely to chip than porcelain/ceramic or PFM crowns.

III. Factors Affecting Dental Crown Durability

Several factors affect the durability of dental crowns:

A. Material Characteristics

The properties of the material used for the crown will affect its durability. For example, porcelain/ceramic crowns are more likely to chip than metal or zirconia crowns.

B. Occlusal Forces

The amount of force placed on the crown when biting or chewing can affect its durability. Teeth grinding or clenching can also put excessive pressure on the crown, leading to damage.

C. Oral Hygiene

Maintaining good oral hygiene is essential to the longevity of dental crowns. Neglecting oral hygiene can lead to bacterial growth, which can cause decay or gum disease, compromising the crown’s durability.

D. Biocompatibility

The material’s biocompatibility used for the crown can affect the surrounding tissues’ health, affecting the crown’s durability.

E. Preparation and Placement of Crown

Proper preparation and placement of the crown are also crucial factors that can affect its durability. If the crown is not prepared correctly or if there is not required tooth structure to support it, it may fail prematurely. Likewise, if the crown is not placed correctly, it may become loose or fall off.

IV. Comparison of Material Durability

When it comes to material durability, not all dental crowns are created equal. Here is a breakdown of the different types of crowns and their relative durability:

A. Porcelain/Ceramic Crowns

Porcelain/ceramic crowns are the most aesthetically pleasing but are also the most fragile. They are more prone to chipping and cracking than other types of crowns. With proper care and maintenance, porcelain/ceramic crowns can last up to 15 years.

B. Metal Crowns

Metal crowns are the most durable but are not as aesthetically pleasing as porcelain/ceramic crowns.

C. Porcelain-fused-to-metal (PFM) Crowns

PFM crowns is made by combining the strength of metal with the natural appearance of porcelain/ceramic. However, over time, the porcelain can chip, revealing the metal underneath, affecting the appearance. PFM crowns can last up to 15 years with proper care and maintenance.

D. Zirconia Crowns

Zirconia crowns are relatively new to the market but are quickly gaining popularity due to their strength and durability. They are less likely to chip than porcelain/ceramic or PFM crowns and can last up to 15 years or more with proper care and maintenance.

V. Conclusion

When choosing the right material for your dental crown, there are many factors to consider. While porcelain/ceramic crowns may be the most aesthetically pleasing, they are also the most fragile. Metal crowns may be the most durable, but are not as aesthetically pleasing as porcelain/ceramic crowns. PFM crown combines the strength of metal with the natural appearance of porcelain/ceramic, but the porcelain can chip over time. Zirconia crowns offer an excellent balance of strength, durability, and aesthetics.
