What are the different kinds of crowns per tooth, which is better to choose

A tooth crown is a prosthesis used to restore a damaged tooth.It restores the shape of the tooth without affecting the chewing function.The main purpose of the crown is to strengthen the tooth and protect it from subsequent destruction.When is it necessary to prosthetize a tooth?

1. If more than 70% of solids are destroyed.
2. Injuries to the maxillofacial device, which led to the loss of teeth.
3. Significant erasure of enamel.
4. Aesthetic shaping.However, there are also contraindications to such a recovery procedure.These include looseness of the teeth, an allergy to dentures, an incorrect bite.What is the crown different from the seal?

Crowns are used to cover teeth that are seriously damaged by caries, which implies full covering on each side.The main difference from the seal is that prostheses are manufactured in the laboratory, and not in the oral cavity itself.To form them, the doctor needs to take a cast from your teeth, and then make an exact copy of them.This is the advantage of dental prosthetics, because it will necessarily take into account the individual characteristics of your jaw, such as bite and movement.When applying the seal, the doctor does not see the general picture, but only what is in the oral cavity, so he is not able to investigate the anatomical specificity of the teeth.

What are dental crowns?

When choosing a crown, the indications for prosthetics, the wishes of the client, and, of course, the cost of such a service are taken into account.Depending on the material used, the prosthesis can be:

1. Metallic . This method of restoring teeth is time-tested and reliable, but the lack of an aesthetic component can be called a drawback.Commonly known are crowns made of ordinary steel or steel with a coating, as well as gold.Gold prostheses are more preferable, because they fit better to the tooth, in view of the softness of gold.However, this feature can be attributed to the disadvantages of metal crowns, because they are erased faster than other types of prosthesis.Such crowns withstand the load experienced during chewing.Important is the fact that they do not contribute to the erasure of adjacent teeth.This type of crown is advised to be placed on the molars( lateral teeth) to hide them when smiling.
2. Metal Ceramic . Quite averaged option.From the name it becomes clear that they are based on metal and ceramics.The lower layer of such crowns is a metal base made of a cobalt-chromium alloy or cobalt with nickel, and the outer layer consists of a ceramic mass.The advantages of these crowns include high hardness and an affordable price.Another argument "for" is their good aesthetic appearance.On the contrary, the big disadvantage of metal-ceramic prostheses is a strong erasure of the opposite tooth.Despite this, the advantages of this type of prosthetics outweigh the imperfections.
3. Ceramic . According to biocompatibility and aesthetic appearance, such crowns are the most successful.Their color is close to the natural color of teeth.Unlike the golden crowns, ceramic crowns are the perfect type for prosthetics of the front teeth.The disadvantages include the high cost of such prostheses, as well as not too high strength, which makes it undesirable to establish them in the molar zone.

There are also crowns made of plastic and metal plastic.Unfortunately, the shelf life of these prostheses is not long: from one year to three years.The introduction of such prostheses is only a temporary function.Perhaps, the big advantage of plastic crowns is a relatively low cost.They protect the sharpened tooth while permanent crowns are being made.

Cost of prosthetics

An important aspect when choosing crowns is their cost.First of all, price will depend on the material of manufactured prosthesis.But this is not all.Also it is necessary to take into account such criteria as the category of the chosen clinic and the expert's experience.On average, prices for metal crowns vary from 700 rubles to 15,000 rubles, cermets - from 3 to 40 thousand rubles, and on ceramic - from 20 thousand rubles.Of course, all the interesting nuances should be recognized directly in the dental clinic.

Installation of prosthetic devices

This procedure is carried out in several stages.Depending on the chosen crown, you have to visit the doctor from 2 to 4 times.Let us consider in more detail the stages of treatment that you have to undergo:

1. Examination. At this stage, you need to take an X-ray.Next, should be anesthesia of the oral cavity.
2. Dissection of the tooth. To make the crown firmly "sit" on the tooth, it is necessary to grind it.Each crown has its own thickness, so the tooth size should be reduced.It is not worth worrying, because the appearance will be repaired with a prosthesis.Sometimes, before the preparation procedure, it is necessary to conduct treatment.This can be a replacement of the filling, and the reproduction of the tooth on the pin( if part of it has been split off).
3. Removing the molds. As you know, each of us has its own anatomical features.This also applies to the oral cavity.To make a prosthesis, the doctor needs to remove the impression not only from the painful tooth, but also from the opposite jaw.This will help create the perfect prosthesis on your tooth.Previously, gypsum was used for this purpose, however, this method brought unpleasant feelings to the patient.Today casts are removed with the help of elastic masses.Then the impression is sent to the laboratory, where the prototype of your teeth is cast. The production of the crowns is a rather lengthy process, so there is a need for temporary prosthetics.As mentioned above, for a short period of time put plastic prostheses.They are cemented with cement, but are easily removed.In general, what is this type of prosthesis for?In order to prevent various irritants, as well as to restore the aesthetic appearance of the teeth( especially if it is a smile zone).
4. 4. Choice of color and fitting. The prosthesis should not be different from your teeth.The doctor will set the color of your teeth on a specially designed scale and pick up the correct color of the crown.The next stage will be fitting the prosthesis, matching all the details.During the last visit, the doctor fixes the crown with cement.

How long will the crown last?

Metal crowns are the most durable.They can serve more than 25 years , without losing its functions.The service life of metal-ceramic prostheses is about 10-12 years.The most durable metal-free crowns - 5-10 years.A very important element of prosthetics is the care for them.However, even the best care can not be saved from subsequent problems such as pain and inflammation, if before that the doctor had poorly prepared the tooth to establish the prosthesis.And yet, several rules for proper care should be remembered.

Care of tooth crowns

In fact, caring for "artificial teeth" is almost the same as caring for real ones.It is necessary to regularly brush your teeth( at least 2 times a day).It is advisable to rinse the mouth after each meal, so that gets rid of the leftover food .Once every six months, always visit a doctor to examine the condition of the prosthesis.You can and should use floss.If the gum begins to bleed, change the toothbrush to a softer one.

Is there an alternative to crowns?

Often it happens that we postpone the trip to the dentist, due to lack of time or financial means.Thus, we sacrifice our health, but there are situations when there is simply no other way out.Summarizing, treatment can be postponed, but first you need to consider all the risks associated with this.And they definitely are.In this case, it is better that consult a physician .

The main alternative to the crown is a seal.Not perfect, but still a way out.The seal can last a long time.The only question is whether it is rational to replace the prosthesis with a filling, if the tooth is destroyed.You will receive the answer only in the dental clinic.

In summary, I want to say that dental treatment is always a costly affair.In terms of time, forces, and however much you want to deny it, money.It is extremely important to remember that nobody cares about your health better than you, therefore it is necessary to approach with a mind to such question as dental prosthetics .Yes, it is not so easy to choose a suitable clinic, but it is not worthwhile to postpone treatment to a remote box.To not regret later, take care of your health now.
