¿What are the types of dental prostheses?
Like other types of prostheses, they can either be fixed permanently or removable. In turn, fixed prostheses can be bridges or crowns; and the removable prostheses can be total or partial.
¿How does a crown or bridge work?
Both crowns and most bridges are fixed prosthetic devices and unlike removable devices such as dentures, it can only be removed by a dentist.
¿When would I need a fixed crown or bridge?
We would recommend a fixed crown or bridge to:
- Protect a weak tooth from fracturing
- Restore a fractured tooth
- Replace a large filling when there isn’t enough tooth remaining
- Cover a discolored or poorly shaped tooth
- Cover a tooth that has had root canal treatment
¿How many appointments are necessary to finish a fixed crown or bridge?
The preparation of dental pieces to receive dental crowns requires two or more appointments. The first step involves examining and preparing the tooth; in the second session we will check the fit and color of the permanent crown or bridge, and in the last session we will cemented. To complete the entire process the patient remains with provisional crowns that will then be replaced by the definitive crowns.
¿What kind of materials are crowns and bridges made of?
The crowns and fixed bridges can be made entirely of ceramic or zirconium, metal, ceramic on metal or acrylic resin.
- Total ceramic or zirconium crowns: it is the most aesthetic material that exists today. They have the advantage of allowing the passage of light through its structure, and allow to generate optical effects very similar to those of natural teeth
- Ceramic crowns on metal: the metal gives good capacity for energy absorption, this type of dental crowns are generally used in the posterior sectors of the mouth. But the metallic core, being completely opaque, does not allow the passage of light as it happens in natural teeth
Acrylic resin crowns: used as provisional or permanent dental crowns
¿How long do bridges and crowns last?
The most important step you can take to ensure the longevity of your crown or bridge is to practice good oral hygiene. A bridge can lose its support if the teeth or bone holding it in place are damaged. Keep your gums and teeth healthy by brushing with fluoride toothpaste after you eat and flossing daily.
