Bridges - a fixed prosthetic design, reminiscent of the bridge, which is attached to the teeth using crowns.
Bridges - this is the traditional method of restoring missing teeth.
It is used to replace one or moremissing teeth. Installation bridge is only possible if the right or left on both sides, there are still empty gap teeth to which it may be attached. These abutments are ground, and they set the crown. On crowns set prosthetic elements replacing a missing tooth.
- Excellent aesthetics
- More comfortable than dentures
- Most addictive
- Usually this cermet structure
- It is necessary to grind the adjacent teeth
- The supporting teeth eventually become loose and may be damaged due to the load when many teeth are replaced (the space between the teeth vital support to high)
- For reasons of preserving bonethe use of bridges is limited. The fact is that after tooth extraction, bone, which kept the tooth is no load, i.e. It does not operate. This results in atrophy and its resorption.
Therefore, from these considerations, the preferred implant, since the implant itself is functioning and allows you to operate the retaining his bones.
They are more expensive than the dentures.
What merdilendovsky bridge
Merilendovsky bridge replaces a missing toothby attaching to the lingual surfaces of the adjacent two teeth of the metal legs. To produce merilendovskogo bridge requires less dissection (turning) of adjacent teeth only with the inner surface of the teeth.
Pros and cons of prosthesis
- It is used in cases where the neighboring teeth healthy.
- It is ideal as a temporary restoration.
- It is short-lived, because metal legs can rastsementirovatsya (come off) from the teeth due to the heavy load.
- Inefficient to be used on the back teeth. It is only used on the front teeth.
As made bridge
On the bridge the manufacturing process is necessary to go to the doctor three to four times.
anesthetic management Before dissection abutment teeth for crowns Dr. necessarily make anesthesia to numb not only teeth, but also the surrounding soft tissue, ie, gum.
Dissection of the abutment teeth
For the production of the bridge need to grind twothe adjacent teeth. The thickness of the metal-ceramic crown is equal to 1.4-1.7 mm. So before you put the crowns on the abutment teeth, you must reduce the size of the teeth, grind them on all sides by the thickness of crowns. Dissections of teeth under the crown, the doctor is seeking not only to reduce the size, but give the teeth a certain shape. In addition to giving a special form in the cervical portion of the tooth is made to yield.
Removal of casts of both jaws
In order to be able to make bridge,which would fit exactly to your teeth, the doctor will take an impression not only with peeled teeth, but also the opposite jaw, in order to be able to accurately simulate the future bridge, given teeth-antagonists. Next impression is sent to the dental laboratory, where it is molded plaster model, which is a replica of your teeth. It is on this model is made bridge.
The choice of color of the future bridge
If the bridge is a cermet, it is necessary,that it did not differ in color from the surrounding natural teeth. To do this, the doctor on a scale of colors define the color of your teeth, taking into account that the color of your future bridge will be selected.
Making temporary bridge
The temporary bridge is made at the time,I am ready to be permanent. The temporary bridge is needed in order to protect the abutments of different stimuli (eg, temperature, if the teeth are alive) and to restore the aesthetic appearance, especially, it is important, if the front teeth. The temporary bridge is typically made of plastic, and it makes itself a physician or the dental laboratory, depending on the particular clinical situation. The temporary bridge is fixed to the teeth with a temporary cement to it easily can be removed during the next visit to the dentist.
Second visit - check prosthesis
If the bridge cermet, in laboratoryget ready first metal base of the bridge - a metal frame. The clinic in your next (second) visit to the exemplary chassis to the teeth, and making sure that it accurately corresponds to them, once again sent to the dental laboratory, is now to cover its special ceramic, due to which the teeth will look at the color of natural teeth .
Third visit - we put the bridge
Once again the doctor is satisfied thatCrown is ideally sit on the teeth, ie, tightly wrapped around them, do not interfere with closing the teeth, check their shape and color, he will definitely show you the final result of their work and to know your opinion on this issue.
After a positive assessment of your doctor will startthe final phase of its work - to fix a bridge on teeth. Crowns are fixed with a special cement. Cement is distributed inside the crown, and the bridge is put on the teeth. Excess cement is removed with special tool.
This option is possible that the doctor decidesnecessary to fix the first bridge on the temporary cement, thus it is required to comment on what has caused this need. After a certain period of time, temporary cement the doctor will replace permanent, only after that work is complete.
