Types of materials used in dental crowns
Four types of material used for dental crowns:
1. Ceramics (porcelain)
2. Metal-ceramic
3. Gold alloys
4. Alloys of base metals
Dental crowns: Ceramics (porcelain)
Ceramic crowns are made from porcelain based material, recommended for tooth restoration due to color, resembling natural teeth. You may need to remove the dentist a little more tooth structure for the application of porcelain. The material can be brittle (in the case of very strong bite), but is highly strong wear.
Dental crowns: Metal-ceramic
In metal-ceramic crowns, molten porcelain is attached to the outside of the metal structure to reinforce the teeth serve as seal and prevent recurrence of decay. When the porcelain is fused to metal, it provides a stronger only porcelain restoration. The dentist removes only a moderate amount of tooth structure. Metal-ceramic crowns are strong and durable.
Dental crowns: Gold alloys
Gold alloys are made with gold and copper and other metals are a strong material which adheres to the tooth structure. Gold alloys are strong wear and fracture and do not harm the opposing teeth with which they come into contact. This material is biologically compatible with the gingival tissue.
Dental crowns: Alloys of base metals
Alloys containing base metals non-noble metals are, but rather reinforce the crown and tooth and provide high corrosion resistance. By having the tooth for placement of these crowns, the dentist removes very small amount of healthy tooth structure. This material is strong and wear soft relative to the opposing teeth.
Who needs dental crown?
To recommend a dental crown, the dentist is based on the following factors that may occur in the patient’s mouth: a broken tooth, tooth wear and low resistance of the enamel structure, lack of a tooth, need bridge, need to improve the appearance of the mouth at the end of endodontic treatment and need to cover a dental implant.
