Fixed Prothesis

They are prosthetic devices such as dental crowns, bridgework, and dental implants that replace missing teeth inside the mouth. Fixed prostheses are not regularly removed, and are used instead of removable dental devices such as dentures and partials. The term can also refer to the associated field of restoration dentistry.

CROWN and BRIDGES

What is dental crown?

A dental crown is a tooth-shaped "cap"  to cover the tooth to restore its shape and size, strength, and improve its appearance.

The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.

Permanent crowns can be made from all metal (such as gold or another alloy), porcelain-fused-to-metal, all resin, or all ceramic.

What is dental bridge?

Dental bridges combine the gap created by one or more missing teeth. A bridge is made up of two or more crowns for the teeth on either side of the gap -- these two or more anchoring teeth are called abutment teeth -- and false tooth/teeth in between. These false teeth are called pontics and can be made from gold, alloys, porcelain, or a combination of these materials. Dental bridges are supported by natural teeth or implants.

Metal Based Crown and Bridges

• Metalsused in crowns include gold alloy, other alloys or a base-metal alloy (nickel or chromium). The metallic colour is the main drawback. Metal crowns are a good choice for out-of-sight molars.

• Porcelain-fused-to-metaldental crowns can be colour matched to your adjacent teeth (unlike the metallic crowns). However, more wearing to the opposing teeth occurs with this crown type compared with metal or resin crowns. The crown's porcelain portion can also chip or break off. Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth. However, sometimes the metal underlying the crown's porcelain can show through as a dark line, especially at the gum line and even more so if your gums recede. These crowns can be a good choice for front or back teeth.

• Zirconium Porcelain Crowns:

  Zirconium Porcelain Crowns are natural looking crowns. They let the sun shine through the material and give a natural feeling. It is preferably used for the front part.

   

• Porcelain Based IPS Bridges:

  They are made of hardened porcelain under pressure. They are preferable for the front teeth because of light transparency.

   

• Zirconium Porcelain Bridges:

  The base is Zirconium compound and it is white. Its stamina is very powerful and back part bridges are very aesthetics.

PERMANENT DENTURES CARE:

People should clean their teeth 3 times a day. Gaps between the teeth and below parts of the teeth must be brushed neatly.

DENTURES MUST BE CLEANED DAILY:

Movable dentures should be cleaned after each meal and washed under water. You should clean your mouth with water as well. Special effervescing tables should be used daily. Bleach must not be used while cleaning. This demolishes the surface of the denture and ruins the protein base.

If you do not clean the dentures, it causes bad smell, fungus and demolishing on the gum.    

WHAT IS MOVABLE FULL DENTURES?

These types of dentures are for people who have no teeth. At first appointment the measures are taken and finished in 4 -5 sessions. It takes a week nearly.

When you have a strange feeling, your dentist will prevent and make the necessary care. The dentures must be taken out before going to bed and cleaned after the meals.
