Fixed prosthetics of teeth
Non-removable dentures fixed on the teeth for the long term. This is – single crowns or bridges (several bits), which fixes the doctor on the teeth that need to be grinding to a specific shape. There is a perception that the NON-REMOVABLE prosthetics teeth should definitely depulpirovat, ie remove them from the nerves, but modern technology allows not depulpirovat teeth. At that time, yet to be made crown or bridge, the teeth are fixed provisional crowns.
Cermet
The most common orthopedic construction is cermet. Metal-ceramic prosthesis frame made of chrome-cobalt alloy. Outside cermets cover strong and highly aesthetic ceramics. As a framework can be used more expensive alloy containing gold and platinum – the so-called “ceramic on gold, which, however, does not differ in the properties of chromium-cobalt.
All-Ceramics-metal along with actively applied technology of all-ceramic (category VIP class). All-Ceramics, ie crown, which is made of all-ceramic masses, different maximum aesthetics while maintaining a high functional properties required for the chewing and other stresses. The main difference between all-ceramic is a “live shine”, as Externally, it practically does not differ from the living teeth. It should be noted that of all-ceramic crowns are more expensive than construction of cermets. This is due to the fact that this type of fixed prosthesis made of high-tech and expensive equipment.
In some cases, the crowns of all-ceramic are recommended to set the tabs are made of the same material. The advantages of such tabs as compared with metal – strength, lack of oxidative processes and hence – durability.
Tabs
In the case of a minor fracture posterior encouraged, whenever possible, to preserve tooth tissue and instead of bits set the tab. Such technology is called – mikroprotezirovanie with tabs. In the manufacture of high-tabs all-ceramic, it looks no different from the surrounding tissues of the tooth and will serve you much longer than conventional filling. Pottery has physical properties similar to those of living tissues of teeth, so it is selected, even the most demanding patients.
Veneers
Restoring aesthetics front teeth can be done with ceramic veneers – thin straps, which are firmly glued on the front teeth. A composite veneer may be directly placed (built-up in the mouth), or indirectly fabricated by a dental technician in a dental laboratory, and later bonded to the tooth, typically using a resin cement such as Panavia. In contrast, a porcelain veneer may only be indirectly fabricated.
