More information about dental crowns
Millions of people in the United States and the world have dental prosthetics to replace a missing or reinforced tooth a weakened tooth. The crown is applied to the part of the tooth that is above the gum line, and is made by various materials by the dentist and dental technician.
Types of materials used in dental crowns

Four types of material are used for dental crowns:
1. Ceramics (porcelain)
2. Metal ceramics (metal and porcelain)
3. Gold alloys.
4. Basic metal alloys.
The ceramic crowns are made of porcelain-based material. Its main advantage is the color, which resembles that of natural teeth and is highly resistant to wear. It is possible that the dentist needs to remove a little more of the dental structure for the porcelain application. Additional attention to the choice of this material should be given to patients who have a very strong bite or tooth-grinding habits due to the risk of fracture of the porcelain or the opposing teeth.
In the metal ceramics crowns the molten porcelain is attached to the outside of the metal structure in order to reinforce the set and provide better adaptation avoiding the recurrence of caries. When porcelain is fused to metal, it provides a stronger restoration than only porcelain. The dentist removes only a moderate amount of tooth structure.
Gold crowns are made of gold and copper and other metals and are a strong material that adheres to the structure of the tooth. Gold alloys are resistant to wear and tear and will not damage the opposing teeth they come into contact with. This material is biologically compatible with gingival tissue. It gives excellent adaptation of the margin of the restoration avoiding caries. Its main disadvantage is the cost and color of the metal that disrupts the aesthetics of the tooth. The
base metal alloys contain metals that are not noble but rather reinforce the crown and provide high corrosion resistance . When preparing the tooth for insertion of these crowns, the dentist removes very little amount from the healthy structure of the tooth. New technology for dental crowns
CAD / CAM technology is the technology of design and manufacture assisted by computer. This technology is used to help dentists and dental laboratory technicians create accurate shapes and sizes for dental restorations, which include inlays, partial crowns with dental cusps (also called onlays), crowns, and bridges The three-dimensional image of your teeth and gums allows the dentist or prosthetist to create the precise design of the restoration or crown. This is an expensive technology and not all dentists use it in their offices.
Who needs a dental crown?
To recommend a dental crown, the dentist is based on the following factors that may occur in the mouth of the patient. patient: tooth breakage, tooth wear and poor enamel structure resistance, lack of a tooth, need for a dental bridge, need to improve the appearance of the mouth, at the end of a canal treatment when there was great loss of tooth structure and need to put a dental implant in place.
What next steps?
If your dentist recommends placing a dental crown, talk to him about the materials that can be used. Ask about the duration of the procedure and what you need to do to make the procedure successful.
This syndrome is becoming more and more common and comes to affect about a quarter of the population of the United States and Europe. Most of the time it starts in adulthood or in middle age and its frequency increases with aging. The number of people affected at age 50 is twice as many cases occurring at 30 or 40 years.
Chest traumas are divided into two major groups: high energy (eg automobile accidents and open wounds, such as a firearm projectile) and low energy (falls to the ground or sports traumas, as in soccer). In the elderly, the most common cause of rib fractures is the fall to the ground of the height itself.
