The use of bridge systems in modern prosthetics is caused by a large number of positive reviews.For more than 3 decades, dentists have been using bridges for 1, 2 teeth and more, which helps to restore chewing properties of teeth, without affecting taste buds, tactile sensations, temperature perception.Such systems correspond in shape and aesthetic properties to the needs of a modern person of any age and sex.In addition, the patient gets used to the model in a matter of days, which facilitates the wearing process.

The essence of bridges, types of materials

The model is, in fact, an orthopedic system for permanent wearing( non-removable).It consists of supporting crowns and artificial teeth, located between them.This makes it possible to establish a tooth bridge for 3 teeth( photo below), as well as 1 or 2. In some cases, the crown is placed on 4 teeth, replacing, for example, the front teeth.

Tooth bridge

Let's look at the types of material depending on the material used:

1. Metal .Quite an unpopular model, because its aesthetic characteristics leave much to be desired.However, it is considered to be the most durable, reliable and durable, and you can buy it for an average cost for an average purse.But still the system is quite massive and heavy, which eventually leads to damage to the supporting teeth.Also, many patients complain about metallic taste in the mouth.In addition, metal is a strong allergen, so the model does not fit all.
2. Metal-ceramic .This model is not less durable and durable than the previous one, however, the aesthetic properties are much higher due to ceramics, which completely repeats the natural shade of enamel and is selected by the color of the supporting teeth.A strong metallic basis underlies all the construction and fasteners.Unfortunately, sometimes it radiates through ceramic material and breaks the aesthetics of a smile.Modern prosthesis is mostly made of white metals( steel, zirconium dioxide, etc.), which makes it possible to hide the system as much as possible.
3. All-ceramic .Such types of dental bridges do not have a metal base.Of course, this affects the strength and reliability of the bridge, but aesthetic qualities at altitude - the model completely imitates the natural enamel.

4. Plastic .The budgetary version of the prosthesis, which allows you to establish a temporary( up to 3 years) design before acquiring a better one.In addition, plastic is a hypoallergenic material, so it fits most customers.Plastic crowns are also selected for the natural color of the enamel and imitate the anatomical fissure structure.This type is inferior in strength and durability to all other models, therefore it is used only for temporary prosthetics.
5. Metallic plastic .This system is more reliable and durable than the previous one.The bridge in this case is made of plastic, while the base and fastening materials are made of metal.Such a design can last 2-5 years provided regular hygiene and careful operation.
   Unfortunately, plastic crowns during this time will change the shade, as they tend to absorb food colorings and pigments( nicotine, wine, caffeine).

Types of bridges for the production and connection method

There are 3 ways to produce permanent bridges:

• The one-piece tooth bridge( photo below) is made of a homogeneous material, which gives it increased comfort and durability.
  

  Bridged prosthesis

• The stamped ( brazed) prosthesis includes supporting crowns and artificial teeth.These elements are welded together, and different metals are used.The models so produced can bring discomfort while wearing, and they are often damaged and destroyed more often than others.
• Adhesive prosthesis is manufactured directly in the human mouth.Modern composites are used for production.This method implies a slight turning of the supporting teeth.The resulting prosthesis has no supporting crowns.In fact, it is an arch of fiberglass, which rests on the grooves made in the supporting healthy teeth.An artificial tooth is attached to the arc.The structure is considered to be the least durable, since it does not have supporting crowns, so it is only used when one tooth is to be replaced.

All bridges have an intermediate part between the supporting crowns. There are several types of this part, depending on the methods of attachment to the mucous surface :

1. Wash .This design implies a space between the mucosa and the bridge.Thus, food residues are easily washed out of the system, facilitating daily care and reducing the risk of development of calculus, caries and inflammation.
2. Tangent .The given system allows the prosthesis to touch the mucous surface one side.It is used for prosthetics of the anterior region of the teeth, which is responsible for the functioning and aesthetic appearance of the oral cavity, the formation of the correct speech.That's why the design is used to install the bridge on the front teeth( photo can be seen below).
   

   Bridge on the front teeth

3. Saddle-shaped .In this case, the bridge is completely fixed on the mucosa without the presence of a lumen.This option is not the most durable and durable, as well as reduces the functionality of the dentition.However, sometimes during the prosthetics of the front teeth it is simply necessary.

How do bridge bridges

Many people are interested in how to bridge the teeth, whether it is a long process, how many stages there are in it.

Bridging prosthesis before and after

To begin with, the dentist performs a sanation of the oral cavity, heals the teeth and gums, seals the root canals, etc.Special attention is paid to the future supporting teeth.The doctor conducts their depulpation and sealing, and then sharpens their shape to install the supporting crown.If they are badly damaged, they are strengthened with special tabs.The whole process is called dissection under the prosthesis.

At the next stage, the doctor, together with the patient, chooses the color of the enamel of the artificial teeth.Then the cast of both jaws is formed and sent to the laboratory, where the technologist will make an individual bridge on the teeth( photos are shown below).

After manufacturing an individual design, it is tried on and adjusted to the patient.In the absence of discomfort or special wishes, the system is fixed, tightly pressing to the teeth.Further check whether the bite remains the right, whether all teeth are closed, there are no obvious differences in the color of the enamel, etc.To consolidate the model, the doctor uses dental cement, which binds the supporting teeth, crowns and bridges.

After installing the bridge on the teeth, the dentist gives instructions for proper care of the fixed structure.

Problems after installation

All orthopedic structures have their lifespan, load limit and require careful attitude and regular hygiene.Failure to comply with simple rules often leads to the fact that the design begins to loosen, break down or fall out.

Many people are interested in what to do when the dental bridge is loose.First of all, this indicates that the shelf life of the prosthesis has come to an end.Sometimes, the cause may be material wear and erosion, and in some cases caries or inflammation develops under the support crowns.

If the dental bridge is loose or broken, you should immediately call your doctor

In this case, you should immediately contact your dentist that he carefully lifts the bridge with special tools and installs a new one using fresh dental cement and otherMaterials.It is strictly forbidden to loosen and remove the structure independently, because you can damage the remaining supporting teeth.The doctor with the help of ultrasound device gently paints cement cement, and then removes the bridge.

If the dental bridge is already broken or jumped off, do not delay the urgent trip to the treating doctor.Now your supporting teeth are vulnerable to infections and external irritants, because they were previously turned, loaded with the prosthesis itself, which in the process of breakage could damage the dental tissue.

With careful care and a visit to the doctor for a regular fit, you can comfortably wear a bridge for many years and please those around you with a healthy and beautiful smile.
