Dental prosthetics

Ceramic-metals

Nowadays, the most popular are ceramic-metal, non-removable dental prostheses. Ceramic-metal with its physical properties is the closest to real teeth enamel.


Preferences:

  1. Using ceramic-metal we can achieve artificial teeth full identity to natural ones.
  2. Ceramic-metal teeth are great in chewing, sometimes even better than your own.
  3. Ceramic-metal is more hygienic than person’s own teeth or metal prosthesis, because dental deposit sticks to it much less. This fact is very important for patients with parodontitis.
  4. Longevity. Ceramic-metal construction precisely fixes to teeth. That is why no food or saliva gets in the cleft between the crown and tooth and crown lasts longer. Nowadays ceramic-metal is the most durable construction used in dentistry. Average longevity of ignoble alloy ceramic-metal is 10-12 years and 15 and more years if the construction is golden or platinum. This longevity of construction can be achieved only using modern methods and materials.
  5. Using ceramic-metal gives the possibility to correct the easiest and the most difficult deformations with the same success and guaranteed outcome.
  6. Precisely made ceramic-metal crown will never cause deformations of gums, their bleeding, will never change its color and contour.

Making

Ceramic-metal is one of the most popular non-removable prostheses. At first metal carcass is made on which layer-by-layer is put ceramic mass, after that it is burnt. Technician makes specially chosen model of construction on which every anatomic details will be made. Every tooth’s load is foreseen.

In that way, ceramic-metal tooth crowns are simple metal crown faced with ceramic.

Use

This kind of prostheses are used in case when tooth destruction level is very high, in order to ensure construction solidity. This can only be made using hard but light metal carcass. Ceramic-metal crowns can be put on the front and back teeth.

Zirconium crowns

For a long time most aesthetic method of lost teeth restoration used to be ceramic-metal crown prosthetics, i.e. crowns made of 2-layered metal and ceramics. Metal carcass ensures construction solidity, ceramic layer – aesthetic.

The essential moment which defines the aesthetic of ceramic-metal is its dark color and metal carcass non-transparence, which needs the salvation of this problem, not quite easy procedures: thickening of opaque and ceramic layers. Precious metals often can help but, they have even yellowier color. We can’t refuse using carcass, ceramic is very weak.

Zirconium oxide – the new ceramic material (non-metal ceramic), is quite solid, very aesthetic, white-colored, biocompatible with tooth tissues.

Prosthetic using zirconium oxide (ZrO2) – zirconium crowns – is the realized dream of patients with high-aesthetic demands, allergic and very sensitive teeth.


Zirconium crowns

Nowadays, there is the possibility to make prostheses on zirconium oxide carcass, which has great aesthetic properties. Fist time the color is chosen not only of ceramic facing, but of carcass too. This gives the possibility to avoid “lighting effect”. Only zirconium oxide based prosthetic gives the possibility to achieve teeth natural transparency. No matter how bright illumination is – new teeth will be just as real ones.

Hypoallergenic property of this material is wide-known in medicine as for a long time it was being used in endoprosthetic. Nowadays that allergic level in population is so high; zirconium oxide gives the chance for every person.

Apparatus which makes zirconium crowns is the last generation technique. Prostheses constructions are very exact.

Therefore, zirconium oxide prostheses are:

  • Aesthetic
  • Light
  • Maximally biocompatible
  • Solid

Non-metal ceramic prostheses based on zirconium oxide – is the modern method, which gives the possibility to satisfy the highest demands of patient.

The high-aesthetic property, biocompatibility and solidness of zirconium oxide makes it the ideal material of front teeth prosthetic.

Removable prostheses

These kinds of prostheses can be put on and taken out by patient independently.

Removable prostheses are used in case when patient has no teeth left or left teeth are not solid and can’t be used for non-removable prosthetics. Removable prostheses should be made in cases of:

  • Three or more teeth are missing.
  • Parodontitis. There can be many teeth in mouth, but they can be movable.
  • One or two chewing teeth in the ending of the jaw are missing.

If patient has less than six teeth on upper or lower jaw, the probability, that this patient should have removable prostheses is closest to 100%.

Preferences

  • Even in cases when all of the teeth are missing prosthetic can be held.
  • Lower prices comparing to other, alternative methods.

Kinds of removable prostheses

  • Partial removable prostheses.
  • Whole removable prostheses.
  • Removable prostheses with soft support.
