What is a dental crown?

Speaking of are porcelain crowns strong ? A dental crown, sometimes known as a dental cap, is a type of restoration (fixed prosthesis) that covers or surrounds a tooth or dental implant. 

A crown is often required when there is a large tooth cavity that threatens the integrity of the tooth’s natural structure. The tooth to be crowned is prepared first, and the crown is usually bonded to the tooth using dental cement.

Crowns can be made from many materials (metals, gold, ceramic with metal, pure ceramic such as E-max and other types), which are usually manufactured using indirect methods. 

A crown is often used to improve the strength or appearance of teeth. While it can be beneficial for the teeth if it is prepared well by a doctor and laboratory, the procedures and materials can be expensive to manufacture.

What types of dental crowns 

Before we discuss are porcelain crowns strong , there are many dental crowns used by dentists, which can be summarized as follows:

1-Full metal crowns

As the name suggests, these crowns are completely cast in a metal alloy. There are many alloys available and the choice of one alloy over another depends on several factors.

Including cost, handling, physical properties and biocompatibility. The American Dental Association classifies alloys into three groups: noble alloys, high noble and base metal alloys.

2-High noble alloys

The noble and high noble alloys used in casting crowns are composed of gold alloys. Gold is not used in its pure form because it is thin and has poor mechanical strength. Other metals included in gold bullion are copper, platinum, palladium, zinc, indium and nickel. 

All types of gold alloys used in dental implants (Type I and IV) are classified in terms of their percentage of gold and hardness, with Type I being the softest and Type IV being the strongest. Generally, type III and IV gold alloys are used and contain (62 – 78% and 60 – 70% gold content, respectively).

3-Base metal alloys

Base metal alloys are rarely used to make full metal crowns. They are most commonly used as part of metal-ceramic crowns as an internal thickness for bonding. 

Compared with noble and high noble alloys, it is stronger and more durable and can be used in thin chips (0.3 mm), but it is difficult to adjust and can cause excessive wear on the opposing teeth. Base metal alloys used in: 

  • Dentistry can be silver-palladium. silver-palladium-copper.
  • nickel-chromium nickel-chromium-beryllium, cobalt, or titanium.

4-Metal crowns with ceramic veneers

It is a hybrid of metal and ceramic crowns. The metal part is usually made of a base metal alloy (called a bonding alloy). Dental crowns made of porcelain overlay metal (PFMs); This means that the metal cover is melted and then a porcelain shell is placed on top of it after placing it in a high temperature oven. 

The metal provides the appropriate strength and intensity, and the porcelain gives the crown a suitable appearance that resembles the natural tooth color, and is suitable for restoring front teeth.

The properties of the metal alloy chosen must match the ceramic used to be bonded, otherwise problems such as chipping or cracking of the ceramic and its separation from the metal can occur.

Dental ceramic or porcelain is used to make crowns primarily for its aesthetic properties compared to all metal restorations.

Zirconia is an extremely hard ceramic that is used as a strong inner material in some all-ceramic implants. Zirconia is relatively new in dentistry so published research into its success and performance in the mouth is limited. 

The zirconia substructure (core) is designed digitally using CAD CAM technology by taking photographs of the patient’s mouth, which are captured using a 3D digital scan directly from the teeth or from an impression or model. 

A block of zirconia is then ground into a soft sintered state. Once milled, the zirconia is transported to a melting furnace where it shrinks by 20% to reach its full strength of 850MPa to 1000MPa.

Zirconium is made mainly of porcelain, with additions of other materials, to give the zirconium greater hardness than regular porcelain. Zirconium crowns are not based on a metal structure and are more integrated with the gum tissue.

They are lighter than porcelain veneers, more wear-resistant than porcelain veneers, and are an excellent cosmetic option but more expensive than porcelain.

Zirconium is a very hard metal that can be relied upon in the manufacture of many shapes of artificial teeth, including prosthetic parts such as dental crowns or veneers.
