Crown and bridge
A crown is a tooth replacement that covers a single tooth, primarily to protect it and to make a potentially damaged tooth look more aesthetic. A bridge is intended to replace several teeth in a row.
Crowns and bridges are permanent types of tooth replacement that extend to the edge of the gingiva and sit on a shoulder made from the material of the teeth so there is no visible border between the replacement and tooth.
The material of the crown may be various: all ceramic, zirconium, metal ceramic and plastic, which is the material of temporary crowns.
Often the tooth is chipped off so much that the crown part of the tooth cannot be used to fix a tooth replacement. Even in this case, it is possible to keep the root of the tooth. Following root canal treatment a post can be glued in the root. The post is very similar to a burred tooth stump and enables the fixation of crown even on severely damaged, destructed teeth.
All porcelain crown is completely free of metal. It is also known as Jacket crown. This type of tooth replacement meets even the highest aesthetic expectations. It is very similar to the original teeth and may be used in patients with metal allergy.
The only disadvantage of all porcelain tooth replacement is that its bending strength is not sufficient for a bridge. Only single crown may be prepared from all porcelain and is not suitable for bridge.
Tooth replacement known as zirconium crown or bridge is the most state-of-the-art solution for a lifelike tooth replacement. Zirconium dioxide is completely metal-free, regarding its aesthetics a perfectly lifelike tooth replacement may be prepared from this raw material. Tooth replacement is made by computer-aided technology of micrometer accuracy so precision and comfort is guaranteed.
The great advantage of zirconium crown compared to all porcelain crown is that its bending strength is enough to prepare bridges from it.
Zirconium dioxide is basically white, so it is a perfect solution in aesthetic dentistry.
Metal-free veneers represent the XXI. century's technology in dentistry and they fulfill the highest aesthetic requirements. Instead of metal we make the coverages, crowns and the bases of the bridges from aluminium-oxide or zirconium-oxide ceramic, which is tooth-colored, that's why it is maximally aesthetic.
The Zirconium frame are so strong that even bridges can be made from them.
Metal ceramic crown
Metal ceramic crown is the most frequently used kind of tooth replacement, mostly due to that it is less expensive than all ceramic crowns.
Metal ceramic crown is called colloquially porcelain crown, though it is not entirely porcelain. This is a porcelain tooth replacement fused on a thin metal frame. Only the porcelain material is visible that completely covers the metal frame.
The colour of porcelain is selected using a tooth colour chart so it can be matched completely to the colour of the original teeth.
Metal ceramic tooth replacement is long lasting and robust but it is less aesthetic than all ceramic and zirconium crowns, as it is not always able to give a lifelike restoration compared to the original teeth even by choosing the most appropriate porcelain colour.
Temporary crown
The primary goal of temporary crowns is to function as crowns for a shorter period of time, until permanent crowns are prepared.
Should any kind of tooth replacement be necessary, usually the preparation of permanent buildup takes a few days. In all cases we ensure that the patient does not have to be without teeth even for a day. We prepare a plastic crown which is not a permanent tooth replacement and does not function as a complete buildup, only provides a temporary solution for a few days until permanent tooth replacement gets ready.
These replacements are also made with computer-aided technology, so often match with permanent crowns in aesthetics and comfort. The aim of this is to ensure a complete life for you even in this temporary period and to ensure the ability of eating and drinking and having a healthy smile.
