Ceramic Crowns

All-ceramic crowns, previously known as “porcelain jackets,” are now made from advanced materials that are visually appealing and lifelike. These materials offer strength and durability comparable to traditional metal and porcelain fused to metal crowns (PFM). When a tooth needs a full coverage restoration to enhance its structure and appearance, it is important to consider how the crown will look and how well it will withstand the pressures of oral function. In the past, only metal or porcelain fused to metal crowns provided the necessary strength to bite and chew without fracturing. Although porcelain fused to metal crowns are still a popular choice for strong, attractive, and durable restorations to repair damaged, decayed, misshapen, worn down, undersized, or root canal-treated teeth, they do have certain limitations. Firstly, the metal margin of a PFM crown may be visible at the gumline, especially when gums have receded. Additionally, due to the presence of an underlying metal shell, porcelain fused to metal crowns do not exhibit the same light handling capabilities as natural tooth structure or dental ceramics.

Benefits of Ceramic Crowns

In the past, there was a trade-off between the appearance and strength of dental crowns. Porcelain or all-ceramic crowns looked better but lacked the durability of porcelain fused to metal crowns. However, this is no longer the case. All-ceramic crowns have made significant advancements and can now achieve incredibly natural-looking results. Thanks to the wide range of materials available today, these crowns are also stronger and more reliable than ever before. Let’s explore some of the advantages of all-ceramic crowns:

1. Natural Appearance: All-ceramic crowns interact with light in a similar way to natural teeth, closely mimicking their translucency and luster.

2. Minimal Tooth Reduction: These crowns can be made thinner, requiring less removal of the tooth structure during the preparation process.

3. Tissue Friendliness: All-ceramic crowns are kinder to the surrounding tissues, potentially leading to healthier long-term results.

4. Stain Resistance: These crowns are resistant to stains and discoloration, maintaining their bright and natural appearance over time.

5. Metal-Free and Safe: All-ceramic crowns are free from metal components, making them a safer option for individuals with allergies or sensitivities to metal.

The choice of material for crown fabrication depends on several factors such as the tooth’s location, the forces it endures, and the desired aesthetics. Different types of all-ceramic crowns are available to meet specific needs. For example:

– Feldspathic porcelain crowns
– Empress crowns
– Procera crowns
– Lava crowns
– Zirconia crowns
– Emax crowns
These crowns cater to different areas of the mouth and fulfill specific aesthetic requirements. Whether it is a back tooth requiring durability or a front tooth needing optimal aesthetics, there is an all-ceramic crown suitable for each case.
