What are crowns made of?
Crowns are made of a variety of materials and new materials are constantly introduced on the market. Different materials are used for different procedures. Gold has been a commonly used material for crowns, though its appearance often precludes its use in the front if the mouth.
Porcelain bonded to precious metal crown is made of a precious metal base and porcelain is then applied in layers over the base. Porcelain crowns can be manufacture to give a tooth- like appearance. They are hand crafted by a dental technician to give characteristics to match the other teeth in your mouth. Porcelain can be crafted to give a high degree of translucency, but because porcelain is inherently a brittle material, sometimes a metal sub-frame will be produced usually made of gold alloy, to increase the strength of the crown. We do not use Nickel –containing alloys.
Porcelain and composite crowns- these crowns are made of a resin material and can look very natural. They are not as strong as bonded crowns and are used as a” long term” intermediate solution for full mouth reconstruction cases. These crowns help the patient to get used to repositioning of the bite.
Gold and Precious metal crowns- Gold and palladium crowns are very strong and hard wearing and are usually used at the back of the mouth. They are nor visible and most suitable for people who grind and clench their teeth.
