Unfortunately, some diseases of the oral cavity inevitably lead to the loss of one or more teeth, even if the correct treatment has been performed. In addition, such situations can arise due to mechanical injuries, strong jabs in the jaw.
To prevent complications and fill the empty space, a dental bridge is installed - an orthopedic structure, which is a permanent prosthesis.
Types of dental bridges
There are several options for classifying the devices in question. They are differentiated depending on the material, technique and installation.
In the first case, the following types of prostheses are distinguished:
- Plastic and metal-plastic. These are budgetary designs that are made of hypoallergenic plastic that mimics natural enamel . Typically, such orthopedic devices are used as a temporary dental bridge before the installation of a permanent prosthesis. Their service life does not exceed 5 years.
- Metal. The most durable and relatively cheap design option. At the same time, these bridges do not meet the aesthetic requirements, they can provoke the destruction of supporting teeth and allergic reactions.
- All-ceramic and cermet. The first specified kind of adaptation is most acceptable in terms of aesthetic functions, but tooth bridges of cermet are more durable and durable. Modern orthopedists prefer a skeleton for prostheses from zirconium oxide.
By the type of fabrication there are such constructions:
- Stamped. Several individual crowns or artificial teeth are welded together.
- Cast. The device is made integral, cast on the basis of a plaster cast made from the patient's jaw.
- Adhesive. The bridge is made directly in the oral cavity. Between the supporting teeth stretches the fiberglass arc, which serves as a support for the prosthesis.
Depending on the place of installation of the orthopedic device, the dentist chooses one of the following options for connecting the bridge and the mucosa:
- tangent;
- washing;
- saddle-shaped.
Which toothbrushes are better?
High quality, durability and strength, providing a long service life (up to 30 years), has a whole ceramic and cermet tooth bridge on implants. Their advantages:
- resistance to any chewing load;
- Immunity to aggressive and acidic environments;
- preservation of the original color and shape for many years;
- not too high price, if you compare the life and cost of construction;
- simplicity of installation;
- an excellent appearance, the prosthesis is almost indistinguishable from real teeth.
It is important to note that the choice of the variety of the bridge, the way it is manufactured and installed depends on many individual factors. Therefore, such decisions are made only by the dentist-orthopedist on the basis of examination of the oral cavity of the patient, the volume and density of his bone tissue, the presence of bad habits and other nuances.
Removing and replacing the dental bridge
If the described design is obsolete or its service life is coming to an end, there are errors in fixation, it is necessary to contact the doctor in a timely manner. Only a professional dentist can perform manipulations to correct the position and fixing of the bridge, remove and replace it, perhaps, to implement another, more acceptable technique of prosthetics .
Independent attempts to clean the structure can end very badly - damage to the bone, soft and mucous tissue, the destruction of supporting teeth, the development of severe inflammatory processes, the attachment of bacterial infection.
