DENTAL CROWN

The dental crown is the natural part of the tooth that protrudes from the gum.

It is also the name given to the fixed ceramic prosthesis that replaces it, in case of severely damaged teeth, and has the shape and color of a real tooth.

It is fixed to the natural tooth with cement and acts as a kind of cap that will cover the tooth.

• If the tooth root can be preserved, the artificial crown will be placed on a natural stump.
• If the entire tooth is extracted, an artificial root will be placed, the dental implant, and the crown cemented on top.

Today and with today’s adhesive techniques, the ceramic crown is indicated as a last resort in the case of extremely deteriorated teeth. The goal is to be as minimally invasive as possible and we make smaller fixed prostheses, called inlays and onlays. Nevertheless, the priority is always to save the natural tooth.

Here are some examples of cases where a crown can be indicated :

• Restoring a broken or extremely worn tooth
• Covering a dental anomaly of shape or color
• Finalizing a dental implant
• Restoring a devitalized tooth

The different materials of dental crowns

Dental crowns are made of several different materials, each with a specific indication.

We use different types of materials for our fixed prostheses, including :

1. The ceramic crown:
   • It is made of an exceptionally strong ceramic framework and perfectly mimics the color of the natural tooth. The ceramic dental crown is a very high quality prosthesis and meets the highest aesthetic standards.
2. The zirconia or ceramic-zirconia crown :
   • Whether externally coated with ceramic or not, the zirconia crown is increasingly being used in dentistry. It replaces the old metal crowns (unsightly and possibly harmful to health). Zirconia has an esthetic appearance very close to that of natural teeth and a good mechanical resistance.
3. The resin crown:

• • • Used temporarily to protect the tooth until the dental technician has made the final crown.
