Dental Crowns: All crown types

Dentists that practice in the implant field make sure of different dental crowns, when each of them have advantages and disadvantages.

When talking about the crown, we are talking about only the protrusive exterior portion outside the gums. The crown is mounted on top of the dental implant, that is (in most cases) screwed into the jawbone – that simulates the tooth’s root.

The crown, makes up for the portion that is visible to the eye, that looks like the tooth itself. Beyond the aesthetic value, the crown comes in contact with food, drink and additional matters that might affect its condition – such as coffee, cigarettes etc.

As such, the importance of the quality of the crown isn’t less significant than the dental implant’s quality (to read about dental implant types press here). The material the crown is made from, its fit according to the patient’s jaw structure, are the key factors to consider when choosing the type of crown, and securing the dental implant treatment that will assure the patient aesthetically pleasing results, and will also allow the patient to function naturally, as if it was his real tooth.

In this article we will review the various common crowns and detail each’s advantages and disadvantages.

Metal Porcelain Crown (PFM)

This crown is made of a metal cast and coated in porcelain. Even with this type of dental crown there are different levels of quality that are determined by the following three parameters:

  1. Medal type: The medal can be basic, noble (gold or platinum) or an alloy combination made from different percentages of basic and noble medals. The higher the percentage of the noble metal used in the alloy the higher the quality is.
  2. The quality of the porcelain
  3. The quality of implant’s built: the dental labs making use of advanced equipment such as 3D printing etc.

Metal Porcelain Crown- Advantages

  • Cheaper price
  • The ability to match it to the jawbone structure by usage of advanced technology

Metal Porcelain Crown- Disadvantages

  • In the long run it might develop a grayish colored hue around the tooth in the gums area
  • The basic metal crowns might develop corrosion

Lithium Disilicate Crown

These crowns, named E-max Crowns, based on noble metal (usually gold) and coated in compressed porcelain combined with glass. These crowns was developed by the Ivoclar company and aren’t very common, even though they are very high in quality and of excellent aesthetic results, and are mostly used in the frontal areas.

Lithium Disilicate Crown – Advantages

  • Bright white coloring, with translucency qualities
  • Excellent aesthetic results that are long lasting
  • The crown’s base is made of noble metal and won’t rust.

Lithium Disilicate Crown – Disadvantages

  • The crown is priced relatively high

A Porcelain blended with Zirconia Crown

The Zirconia is a crystal type of mineral, very strong and of high resistance and strength properties. As such, the Zirconia is used commonly in the jewelry industry as an artificial diamond but in the past few years has been utilized in the dental implants field.

The Porcelain crown blended with Zirconia is made from combining between the zirconia and porcelain, when the crown’s base is zirconia and above it is the porcelain casting, so that the crown merges qualities from both materials.

Porcelain-Zirconia blended Crown – Advantages

  • Excellent aesthetic look
  • The price of this crown, is relatively low
  • The crowns can be designed and fit to the jawbone structure optimally

Porcelain-Zirconia blended Crown – Disadvantages

  • The crown’s shade changes over the years
  • Not optimally stain resistant (coffee smoking etc)

Pure Zirconia Crown

Pure Zirconia Crowns are considered the leading dental solution of the highest quality in the dental implant field. The crowns are made from a zirconia cast’ that is engraved in a laboratory with robotic equipment, without the touch of a human hand, after a 3D design and simulation of the tooth structure.

 Pure Zirconia Crown – Advantages

  • Pure Zirconia crowns are strong and resistant to wear and tear.
  • Highest accuracy in fitting to the jawbone structure
  • The crown’s coloring stays intact for many long years

 Pure Zirconia Crown – Disadvantages

  • The crown’s price is relatively high
  • The Zirconia crowns often grind and harm the natural surrounding teeth (in case of a partial implant)
