Teeth bridge

Features

The dental bridge is called so, because externally it is similar to the engineering structure of the same name. The prosthesis is designed to restore chewing function and aesthetic appearance. Artificial crowns, sometimes with imitation of a part of the gums, are supported on 2 points. This can be the patient’s own dentition or stump inserts reinforcing damaged units. Implants are also used as a support.

Dental bridges also differ in the lower part. Depending on the degree of adherence to soft tissues, there are the following:

• flushing - the gap between the gum and the bottom of the prosthesis allows you to clean and rinse the cavity;
• tangents - the distance is minimal, which allows you to save speech and chewing functions and not damage the mucous membrane. As a rule, a dental bridge is installed - of this design on incisors and fangs;
• saddle - the dental bridge fits tightly on the gum, the prosthesis puts pressure on the tissue.

In the case of prosthetic incisors, it may be the only option.

The installation of a bridge on teeth in a "Sa-Nata" Clinic differs depending on the material the prosthesis is made of and the method of its manufacture.

Kinds

Bridges for teeth are made of different materials:

• metal - the oldest and budget option. They are very durable, however, they can cause an allergic reaction, discomfort and have a not very aesthetic appearance. In addition, they are fixed with metal crowns and create a load that gradually destroys the bearing units;
• cermet - thanks to the metal base they are durable, and the ceramic coating increases aesthetics. But the coating quickly wears out, becomes thinner, impregnated with dyes and loses its appearance;
• ceramic - light, beautiful, but fragile;
• plastic - cheaper than ceramic, but short-lived, although they look like natural crowns. A plastic bridge is placed on the teeth temporarily and only on incisors and fangs - where the load is lower;
• metal-plastic - have the strength of metal, but because of the plastic structure on average serves 2-5 years.

In addition, the bridge for the teeth is made using various techniques:

• stamped or brazed - this design combines support crowns and prostheses connected by soldering. However, such designs are a thing of the past due to low strength, discomfort caused by contact of living tissue with solder;
• cast - casting of the entire structure is carried out according to the removed wax models. Such a dental bridge has a high degree of strength and convenience;
• adhesive - the device is attached to the supporting crowns using a fiberglass arc, laid in the neighboring saw files. It is fixed with special glue. Due to the low strength, such a structure is used with the loss of 1 unit.

Modern prosthetics methods have undergone significant changes over the past 30 years. Thanks to 3D modeling, new diagnostic methods, dental bridges ceased to be inconvenient, began to serve much longer.

Installation steps Before putting a bridge on your teeth, a "Sa-Nata" Clinic dentist examines a patient’s oral cavity in order to identify the crowns to be treated and to assess the condition of the support units. After the rehabilitation of the oral cavity, the specialist performs the following operations:

• prepares anchor points - he ellipses, seals the canals (if necessary), grinds, and if they are not held firmly in the jaw, are too mobile, they are strengthened with special tabs, and set pins;
• makes casts of jaws, determines the color of enamel so that the prosthesis does not differ from native crowns;
• in the laboratory, on the basis of the obtained casts, a bridge is made, the teeth of which match as much as possible in color, size with natural ones, and the inside of the crowns repeats the configuration of the support units;
• for a while, while the laboratory is being constructed, a temporary prosthesis is installed;
• the finished design is installed in place, it is tried on. If the patient feels uncomfortable, for example, the teeth do not close, the bridge is sent for an exact fit in the workshop. If the implant fits perfectly, then it is firmly fixed. Sometimes discomfort occurs during operation - after a few days. In this case, you need to contact the prosthetist for correction.
