Fillings.ws: A detailed description of all types of fillings, materials, manufacturers

Amalgam – once the most common material, which is based on a combination of metal and mercury.

Pluses amalgam

* High-strength material, which can last more than a decade
* Material is easy to use
* Do not react to moisture and saliva (which eventually grind down a number of filling materials)

Disadvantages of amalgam

* The presence of mercury may be harmful to health (a small, because the amount of mercury is low)
* Material greatly expands, increases in size, which may lead to the fact that the seal will go beyond the sealable cavity. Since the material is very durable due to its rapid increase in size may occur cleaved thin side walls of the tooth.
* Aesthetic form seals – the color is very different from all other teeth (mold metal shade)
* The time for hardening of the material – 2-3 hours

Due to the large number of deficiencies, this material is almost never used in modern dentistry and is considered a relic of the past

Fillings of glass ionomer cements.

This cements a new generation who have a number of positive attributes – high strength, durability, resistance to various influences and high cosmetic effect.

Fillings svetopolimernyh materials.

Dental fillings svetopolimernyh materialovEto can be both light-curing cements and composites or composite resin (compomers). The characteristics of these materials is that they have adhesive system that allows the seal firmly into the tooth through the active attachment to the surface. Solidification svetopolimera occurs only under certain special lamp light spectrum. Svetopolimer enables the dentist to create such a seal, what you need. Therefore, the use svetopolimernyh materials allows to put the seal on a variety of tooth surfaces, front and back teeth, restore the cleaved fragments of teeth, to form a seal flush with the surface of the tooth, just select the desired color.

Fillings

Types plombSegodnya in the arsenal of any modern dentistry has a large selection of dental fillings, which are notable for their durability and safety. They are used for dental restorations, including those damaged by caries.
Types of fillings

Seals are different composition, aesthetic properties and validity.

Depending on the age of distinction temporary seals (installed temporarily, later replaced by permanent) and permanent seal.

In composition, are distinguished: Variety of fillings

* Metal fillings – are composed of metal alloy with mercury (amalgam). Serve more than 30 years, but are considered to be unsound because of mercury content.
* Cement fillings – a convoy with glass ionomer cement, which has antibacterial properties and is securely attached to the tooth.
* Composite fillings – fillings chemical curing on plastic filler in most cases is porcelain. Such seals slowly erased, less toxic, but eventually darken. Bleaching of seals is not possible.
* Photopolymer fillings- svetotverzhdaemye composites, the most modern form of seals, which has ductility, high strength and does not change color over time. Most often they are used for the treatment of dental caries on anterior teeth.
* Ceramic fillings- identical dental tissue and is absolutely harmless. Preclude development under the seal of secondary caries. However, such seals are difficult to manufacture: The process takes about a week. First, the doctor makes a silicone mold of the tooth cavity. Then, the dental technician produces a form for casting ceramic seals, burn it in an electric oven, glaze and polish.

In addition to the restoration of teeth with conventional seals used to seal the restoration of the pin. The doctor chooses this method of recovery if the nerve is removed and the tooth is still strong. Pin serves as a frame seal.

Also teeth without nerves can restore metal-ceramic crowns and tabs. The tab is made by a dental technician in silicone model, a previous cavity, and therefore an ideal material for tooth restoration.

Usually, the dentist decides to use a tab, or seal the crown for the restoration – it depends on the degree of tooth decay.
