Recovery of the destroyed tooth (pins and crowns)

Recovery of tooth — rather popular procedure which is directed to restoration of the injured tooth. Need of recovery of outward and functions of teeth arises in case of partial or their final fracture. Also restorations can be subject the uneven or erased teeth.

If you have in whole or in part the destroyed tooth in which nerves are removed, and do not want to get rid of it and to insert an implant, then stomatologists can suggest you to recover it. In spite of the fact that tooth with the sealed-up channels is considered lifeless owing to what its fabrics are not fed and are gradually weakened, the modern stomatology offers several ways of recovery of such teeth. Important function of recovery of tooth is reliable closing of entrances to channels of tooth, and besides, restoration has to recover tooth without unpleasant feelings and complications, such as a granuloma and a cyst of tooth. Even if from tooth there were one roots, it can be recovered, it is much better, than an implant or the bridge.

Causes of destruction of teeth

Causes of destruction of teeth exist in a huge number. The main of them are: not cured caries, the dropped-out seal, a tooth injury, a tooth wall chip, and also the increased erasability of teeth. All factors promoting injury of tooth can be divided on internal and external.

Mechanical, chemical and temperature impacts on teeth, and also non-compliance with personal hygiene of an oral cavity belong to the external factors promoting development of caries and the subsequent destruction of teeth.

Internal factors are disbolism, and also unbalanced, a hyponutrient. Stomatologists advise to recover tooth even if the chip leaves far under a gingiva. Operation is offered to be done only in case of a fracture of fangs when it is already impossible to recover it.

If you damaged or lost part of tooth, do not tighten a campaign to the dentist because it can become an infection source in an organism, there can be periodontitis. Besides, neighbors of the destroyed tooth will have no support that can lead to the fact that they will begin to bend towards a blank space. Similar defect will be very difficult to be corrected.

Ways of recovery of teeth

There are 3 ways of recovery of the injured tooth:

  • seal on a pin
  • bayonet tooth (tab)
  • crown

On reception, the stomatologist will estimate extent of destruction of your tooth, and also quality of sealing of channels — existence of emptiness and density. In case of defects, can carry out also a pereplombirovyvaniye of channels.

The choice of a method of recovery of pulpless tooth will be chosen by your attending physician, being based from extent of his destruction, on a condition of a parodont, a condition of an oral cavity in general, your way of life and age. It is considered that for high-quality recovery of tooth a seal on a pin, defect should not exceed thirds of volume of coronal part of tooth. Restoration by means of bayonet tooth tab it is the most optimum to carry out at destruction of tooth approximately on a half of its volume, and at destruction of tooth it is more than on a half, the best option will be to recover it by means of a crown.

Recovery of tooth a seal on pins

It is possible to recover tooth a seal on pins if the nerve of your tooth was removed, but walls and tooth remained rather strong. Very important at the same time a condition of a fang, it has to be strong, and the root channel qualitatively sealed up. In this case the doctor will advise you to recover tooth this easy way in which the pin acts in the form of the support coming in the channel which supports a seal.

Distinguish anchor, fiber glass, parapulpal and uglerodovoloknisty pins. Anchor pins are made of brass, titanium, platino - gold-palladium alloys, and happen active and passive. Active pins have a carving thanks to what are rolled in cement at installation, passive keep only by means of cement.

The stomatologic pins made of fiber glass are transparent thanks to what they can be established on foreteeth. Uglerodovoloknisty pins are very strong and I use them generally for prevention of root changes. Pins happen screw, cylindrical, conic or combined.

The technology of recovery of tooth a seal on pins rather simple, and anesthesia in stomatology does it also painless. The special tool material from the sealed-up channel partially is removed, and the pin is fixed on cement with calling a bone for bigger stability. After that, tooth is recovered by means of sealing material which accumulates in the small portions at each other, repeating a form and color of tooth, and hardens by means of heating by a special polymerization lamp. Then the processed tooth is ground and polished.

Composites which are rather long-lasting, strong belong to modern sealing materials and well svetopolimerny materials which have a glue basis that allows a seal to fasten strong to tooth connect to tooth tissues, and.

Recovery of tooth with a seal on pins — rather inexpensive and fast procedure, however and very unreliable since walls of tooth will continue to become thinner that can lead to final fracture of tooth, and it it is necessary to delete. Besides, also secondary caries can develop.

Recovery of tooth bayonet tooth

Восстановление разрушенного зуба (штифты и коронки)If tooth is not strongly destroyed, the doctor can suggest to recover it by means of bayonet tooth (tab) — the special design consisting of ceramic coronal part and a pin which is entered into canals of a root and recovers a missing piece of tooth. Earlier coronal parts were produced from a kabalkhromovy alloy, the ceramics or a keramer is generally used now. Bayonet teeth can be used for recovery of teeth of all types. In this case, the doctor partially rasplombirovyvat channels, removes molds and fills a temporary tooth. In dental laboratory on a mold make the specified integral design which is precisely reflecting missing part of tooth which then and is fixed on cement, and prishlifovyvatsya on a bite.

This method of recovery of tooth has a number of advantages as tooth tab — rather strong design, as well as stomatologic pins, it capable to resist to long loadings, and at the same time sparing to enamel of the next teeth. Besides the design executed in laboratory from a mold, usually very qualitative and exact.

However, in connection with thinning of walls of tooth and development of secondary caries, this design can drop out. Besides, pulpless teeth begin to darken over time, and can differ on color from a design.

On pins it is necessary to watch teeth which were recovered by means of bayonet tooth (tab) or a seal and if they begin to disturb you or change the color, it is worth addressing the stomatologist and to cover them with a crown.

Recovery of tooth crown

Recovery of teeth by means of crowns is the most widespread method of restoration of teeth. Tooth crowns use for recovery of outward and functions of the teeth having defects, destroyed by caries or as a result of an injury. Earlier stamped crowns from precious or medical alloys were widespread, however now the preference is given to modern materials which look more naturally and naturally.

The most popular crowns are ceramic-metal, consisting of two layers — a framework from metal and a ceramic periblast. Ceramic-metal crowns are rather strong that provides a metal framework, and the layer of ceramics applied on it gives to a crown an esthetic look. Similar crowns can be used for recovery both lateral, and foreteeth. Depending on a situation, similar crowns can be made so that the ceramics covered only certain parts of teeth, and other part of a crown can be made metal. As metal use kabaltokhromovy alloys, titanium, alloys with gold, silver or palladium which are not oxidized. All possible shades of teeth without cyanotic metal shade allow to transfer modern technologies very precisely.

It is possible to carry to shortcomings of such type of crowns that the metal framework under a ceramic surface can sometimes be shown in the form of the dark line at edge of a crown that is not really esthetic. Besides ceramic-metal crowns, thanks to the durability, promote strong wear of opposite teeth.

The tselnokeramichesky crowns made of porcelain or other ceramic material which allow to give to a crown color of the real tooth are also very esthetic and look naturally and esthetically. The ceramics is not oxidized, is not erased and does not make negative impact on an oral cavity, however such crowns concede to others in durability therefore most often they are put on foreteeth. Besides, tselnokeramichesky crowns very expensive.

Ceramic crowns on a translucent framework from zirconium oxide are the most sparing for tissues of teeth in comparison with other crowns. Similar crowns are made in two stages. At first the crown framework is made of zirconium oxide, and then the framework of a crown becomes covered by ceramic weight. Crowns from zirconium oxide are very long-lasting and do not change the color for a long time.

Восстановление разрушенного зуба (штифты и коронки)The crown is put on the tooth recovered by a seal with a pin or a kultevy tab. The Kultevy tab is made of the same material, as the framework for a crown and represents the design coming into root canals and recreating a tooth stump which the crown is put on. The Kultevy tab undertakes part of chewing pressure, promotes its uniform distribution to all root. For example, if you want to recover tooth by means of a crown on a zirconium framework, then the stump of tooth has to be executed from a seal on fiber glass pins or tabs from zirconium. In case of strong destruction of tooth, the crown and a tab for its recovery have to be made of biocompatible materials, for example, of zirconium oxide.

Recovery of tooth a crown happens on stages: a partial rasplombirovyvaniye of root canals and removal of a mold from gypsum under a tab then to you to be filled a temporary tooth. The picture is removed not only from the recovered tooth, but also from an opposite jaw that will help the technician to consider features of a bite at production of a tab. In laboratory on a mold the tab from metal is cast or turned by means of the laser from zirconium. Then, the stomatologist cements a tab in fangs and grinds it and part of own teeth under a crown. It is very difficult work since it is necessary to create a thin uniform ledge about 0,5-2 mm thick that the crown sat ideally. Then from both jaws molds for a crown are removed, and to the patient to be put the temporary crown. The temporary crown or a plastic prosthesis protects tooth from various irritants, and also creates visibility of presence of tooth. The crown framework is in vitro turned or cast, and then the ceramics gives all the best manually and is baked in the special furnace. Then the doctor by means of cement fixes a crown on tooth. Cement is evenly distributed in a crown then it is put on tooth. It is very important that the crown precisely adjoined to tooth. All procedure usually to last about 2 weeks.

The main advantage of crowns is that tooth tissues remain better since usually the crown sits densely and hermetically therefore neither microbes, nor saliva under a crown get therefore caries does not develop. Ceramic-metal crowns — very strong, and do not change over time the color. However crowns — rather rigid designs that is not good for opposite teeth. Besides, the gingiva because the crown is a foreign subject, can begin to be removed. To avoid it, crowns put on a tooth ledge, but is not deep in a gingiva, and also recommend crowns with edge from biocompatible materials or with integral ceramic edge. Ceramic crowns are considered as the most esthetic crowns which put on foreteeth, and crowns on a framework from zirconium oxide therefore they are put on lateral (chewing) teeth are considered as the strongest. The crown has to repeat all cavities and hillocks of tooth and to sit as natural continuation of tooth — without jags, besides, it should not disturb. If you feel discomfort, see your attending physician who will be able to polish a crown.

The address with the recovered teeth

Behind teeth which were recovered by means of bayonet tooth (tab) a seal on pins or crowns, it is necessary to look after very carefully and to make thrifty use of them. It is impossible to forget about individual hygiene of an oral cavity, and observance of such simple rules as the correct and regular toothbrushing, use of a dental floss and conditioner. It will well affect a condition of your teeth and the established designs. It is also necessary to pass routine inspections regularly.
