Dental crowns, bridge (non-removable dentures)

Bridge - a bridge reminiscent of fixed prosthetic design, which consists of two crowns or pin artificial teeth on the edges, is fixed at limiting orthopedic defect teeth.

The main indications for the use of bridges:

• Lack of 1-3 teeth in a row;
  
• Having teeth or implants edges of defect.
  

The absence of even a single tooth can cause serious strain dentoalveolar:

• Overloading the remaining teeth;
  
• The slope of the teeth and convergence towards the freed space in the jaw;
  
• Nomination of tooth antagonist (opposite jaw, which was in contact with him);
  
• Stimulated wrong chewing involves jerking of muscles, joints overload it.d.

That is why, even with the loss of a tooth, it is necessary to replace the tooth on the implant or, failing implant formulation bridge.

Be sure the edges of the defect need stable teeth or implants. Fix dental bridge one edge on the tooth, and the other on the implant is unacceptable: because of the different abilities of depreciation during chewing design will serve as a lever to undermine the natural tooth and

Often, non-removable denture can capture not only the two teeth on the edges, but more of them, in addition shiniruya moving because periodontal disease teeth.

Between the supporting crowns bridge located intermediate portion - an imitation crown missing teeth, gums and between them must be clearance - flushing space. Visually imperceptible to others, but it is essential in order not to complicate oral hygiene and not to burden the gums.

The bridge is attached to the tooth fixed with special filling materials. Correct fixing it is very important for the prevention of periodontitis, dental system overload, so orthopedic surgeon first sadit bridge temporary cement - gives the patient time to check how they feel comfortable with it, and not allowed any errors on one of the stages of treatment.

Depending on the materials used, dental bridges are:

• metal
  
• plastic
  
• ceramic
  
• combined
  
• Metal-free
  

Pure metal is no longer used because of their poor aesthetics, and stopped using plastic because of its fragility and instability of color. The most common are now considered non-metal and ceramic-metal construction (with a frame made of aluminum oxide, zirconium oxide).

There are both solid and composite bridges. The latter may be removable or detachable conditional. But such designs are not the most accessible, so the most common non-removable bridges solid bridges.

As a support crown prosthesis can act tab, the pin tooth polukoronka and various combinations thereof.

Any of the above types of prostheses produced in the laboratory. The framework of the bridge can be soldered, fully molded or carved out of aluminum oxide or zirconium technology CAD \ CAM. Brazed now almost never made because of the many flaws Solid and non-metal - the undisputed leader in all respects.

Adhesive bridges - a structure for fixing that do not need to resort to installing crown. This is an artificial tooth that replaces the missing, which is attached by means of filling materials to the adjacent teeth. Disadvantages of technology has, in fact account for the prepared teeth.

To bridge was stronger, some experts began to use the wire at its core - beam system. This option is ideal if limiting defect teeth have cavities or large fillings. If they are intact, do not want to sacrifice them all, so doctors recommend the resort to implantation.

Modern technologies have gone far ahead, so now bridge on the front teeth can be made even in the absence of all four incisors in the jaw (or 2 premolars, molars 1).

Non-metal and metal prostheses have almost the same ceramic coating, but their production processes are substantially different.

Frameworks for zirconium oxide or oksidalyuminievyh prosthetic models and mills special computerized device, which makes them extremely accurate and does not require correction. In addition, the material is so durable, it is virtually impossible to break (only for special efforts in their hands, and then can not please everyone). Metal-free frames are light and do not shine through ceramics, bridges based on them can be distinguished from natural teeth do not even every dentist. The process will take from 2 to 4 visits.

Production of metal-ceramic bridges includes clinical stages (removal of impressions, fitting and adjustment of the cast frame design verification in the mouth and its fixation) and laboratory (manufacture of individual models, simulation framework, er casting and machining, coating ceramic tiles and baking). On average, for the installation of a combined bridge may need 3-5 visits.

How much will the bridge depends on the extent of the defect, the materials used, methods of manufacturing design. If you know about what options you might come up, you can contact your dentist orthopedic and learn the value of unity, ie 1 crown or artificial tooth.

But it is worth remembering that the manufacturing steps of a bridge and their nuances knows a doctor, depending on the complexity of the clinical situation may require additional costs. In addition, the main task of the doctor - do not do everything on the principle of "customer is always right", and to determine their needs and effective treatment, taking into account the individual characteristics of orthopedic problems. Sometimes prosthetic bridges can only do harm.
