Options for replacement of teeth. Dental Prosthetics
Do you know what are the options for replacing teeth? If you have lost one or more molars, you need prostheses. And, you need not only to restore the aesthetic appeal of your smile. It is known that if at least one tooth is missing, the neighboring load will increase, and their service life will decrease. In addition to everything, the bite is broken, which will lead to a deterioration of the overall health of the oral cavity and gum disease.
In clinics, doctors offer various options for replacement of teeth. Restore the lost can be a variety of methods:
- implant implant, which is installed in place of the lost tooth;
- installation of crowns( this method is used if any part of the tooth or its root is preserved);
- by manufacturing of the bridge prosthesis, which is attached to healthy teeth, placed next to the missing.
When deciding on the method of prosthetics, the dentist always studies the clinical picture. If the tooth is present and depulled, the doctor can install the crown. If removed - he chooses either implantation or a bridge prosthesis. Implants are indicated if the teeth placed to the right and left of the defect are not depulpated and healthy. To mount the bridge, the dentist liquidates the pulp and sharpens the edges.
If the tooth is badly damaged or shattered, the doctor can remove it and then prosthetically.
The options for replacing teeth are not widely known. Implantation differs from prosthetics with the help of crowns only by fixing the crown area of the tooth. In the first case, the structure is attached to the implanted implant, which performs the function of molar root. In the second - it is worn on the preserved part of the tooth, previously reinforced with a pin and enlarged with the help of filling materials or a cultic nozzle.
Crowns are identical in both the first and second versions. They are made of different materials:
- metal-free ceramics.
And now we will start to closely study the options for replacing the teeth. Metal crowns with gold plating or polished metal in dentistry are used mainly for the reconstruction of chewing molars, which are not visible when opening the mouth. They are most often cast from chrome-cobalt alloy. These crowns have the following advantages:
- long service life( minimum 12 years);
- high reliability and strength;
- low cost;
- a small degree of turning of teeth( as opposed to pure ceramics or cermets), which increases their durability.
Dental prosthetics are a complex science that every specialist should study. Metal-ceramic crowns between porcelain and iron take an intermediate place in strength, aesthetic qualities and price. They are made of several materials: inside there is a steel frame, and on top - a ceramic coating. The frame gives the crown stability and strength, and the coating allows to give a natural appearance to the prosthesis.
Metal-ceramic crowns have the following advantages:
- service life - from 10 years or more;
- high reliability and strength;
- is a good aesthetics.
It should be noted that from the artistic point of view these crowns are inferior to all-faceted ones. After all, there is an iron frame inside them, they are not completely transparent and this is different from real teeth. If a single metal cermet is fixed on the front molars, the difference between it and other teeth will be noticeable. If the whole series of visible molars is made of this material, they will look natural and beautiful.
Crowns made of cermets have such disadvantages:
- tooth should be impressively polished from all sides, as the thickness of such a crown is too high;
- molars must be depulled( usually frontal).
Sometimes dentists make prosthetic devices consisting of crowns made of different materials. Thus, the total cost of prosthetics is reduced.
If the bridge includes both frontal and posterior teeth, the first can be made from cermet, and the latter - from pure steel. Iron molars for strength and other indicators are no worse, and savings can be up to 30-40%.
Ceramic crowns are made from zirconia or porcelain. They do not have a steel frame and are entirely made of earthenware high-strength raw materials.
Only single crowns are made from porcelain, as this material is not suitable for bridges. These products can be manufactured in two ways: by injection molding and by layer application. Crowns created by the first method are much stronger.
Porcelain product has the following advantages:
- excellent aesthetics( it is almost impossible to distinguish it from natural teeth);
- manifestation of resistance to various effects( porcelain does not deteriorate over time and does not darken).
Zirconium crowns consist of a frame made of zirconia and porcelain. The frame of the device is very strong. In addition, it misses the sun's rays, so that the aesthetics of the crowns improve.
They have such positive qualities:
- durability and high strength;
- excellent aesthetic qualities;
- the appearance remains unchanged for a long time.
Both varieties of ceramic crowns have the only drawback - a high price.
And now we will consider removable prosthetics. Plug-in bridges are divided into several groups:
- removable full plastic plate prostheses;
- removable partial prostheses( lamellar plastic bridges and implied prostheses, clasp jaws, removable sectors of dentition);
- conditionally removable bridges.
Plastic dentures made of acrylic. They are in great demand in dentistry, because they can be used by people of different ages. Plastic designs are used with full or partial absence of teeth. They can be:
- removable and non-removable;
- pressed and molded;
- are temporary and permanent.
Reconstruction of molar
What is a removable prosthesis for one tooth? If you have destroyed or removed a molar, the dentist will install a cermet crown. Unfortunately, sometimes this can not be done for various reasons. The only solution in this situation is a replacement prosthesis.
It can have an internal concave part, which is necessary in order to cover the damaged tooth. If solid fabrics are completely absent, then a solid device is used.
A removable denture for one tooth can be attached in various ways. Depending on this, it can be of several kinds. The prosthesis on the clasps is the most famous kind of such a system. It consists of a basis, the molar itself and a pair of locks covering the natural teeth. Basis and locks are made of plastic or nylon. Their texture and color are the same as for natural gums, so an artificial tooth is quite difficult to notice.
Features of wearing and care
So, we have practically studied removable prosthetics. If the prosthesis for one tooth is removable, this does not mean that it needs to be removed every night. Today, the patient can wear the designs for months, without feeling any inconvenience.
The device must be removed once a week for disinfection in a special solution. Teeth with such a prosthesis can be cleaned, as is customary, since it is not necessary to remove it. This nuance is distinguished for the care of such devices from the cleaning of conventional bridges.
How much does a tooth replacement cost? The price is affordable for all patients, since low-cost plastic is used to create such a product. For a synthetic tooth will need to pay about 1000 rubles. Some clinics are asked to purchase clas- sers separately.
If such a design is used as a temporary replacement for a metal-ceramic crown, very often its price is already included in the total cost of the service.
