Mankind has been confronted with problems with teeth all the time, starting almost from the first days of its appearance. And sometimes these problems lead to the fact that people resort to drastic measures. For example, in the Middle Ages, all residents of Japan, regardless of gender, covered their teeth with black varnish, which made it possible to hide all the flaws. The absence of some teeth was also not noticeable. Fortunately, in our time, a similar problem is solved in a more civilized way - using acetal dentures.
Why exactly acetal? There are certain reasons for this, which will be described in this article. This material has its own characteristics, due to which this type of dental prosthetics is widespread.
general information
Despite the fact that implantology in dentistry is becoming increasingly successful, the removable type of prosthetics does not lose its popularity. Such prostheses are still simply very popular among people in many countries of the world. The explanation is quite simple: the availability of products for a wide audience of any income.
In addition, manufacturers of removable orthopedic structures are not going to stop in their development and acetal arch prostheses are a vivid example of this. It is due to this material that the products are durable, reliable and comfortable. Otherwise, it is called polyformaldehyde, which, in fact, is a synthetic resin. The chain is represented by three elements:
Due to this, the material is completely safe when using prostheses and is not able to cause allergic reactions. Dentists have recently begun to restore the dentition using similar orthopedic products.
But in such a short period of time, acetal arch prostheses managed to earn the trust of many patients and the doctors themselves. Often they are compared with metal prostheses, but these products look more aesthetically pleasing. They are also more durable and invisible when a person smiles, in addition, dentures do not require complicated care, you quickly get used to them.
New in Dentistry
The emergence of new material, we are obliged to the Italian company Pressing Dental. Acetal orthopedic designs are distinguished by a rich color scheme, which consists of 3 pink and 17 white shades. Thanks to this diversity, the dental technician is able to return to patients their lost smile. Additionally, the prosthesis can be coated with photopolymer dyes and then artificial teeth cannot be distinguished from these elements. You can verify this personally by looking at the photo of the acetal prosthesis.
But in addition to the prostheses themselves, elements of clasp prostheses can be made from acetal - clasps, frames. This will give the structures lightness, attractiveness, which is much better than products with metal arcs. Such fasteners do not harm enamel and allergic reactions do not occur.
Often, acetal and nylon prostheses are equated with each other in quality. But at the same time, there is a difference between these materials. Acetal products are more rigid and they are much more securely fixed in the oral cavity.
The advantages of a new type of prosthetics
Such orthopedic products have a lot of advantages, due to which they are widely used in many dental clinics. Moreover, they are due not only to the property of the material itself, but also to the design. Of course, one cannot deny the fact that any temporary products have their pros and cons; an acetal prosthesis is no exception. But it’s better to start with positive qualities:
- Strength - according to this parameter, acetal products are not inferior to metal analogues and can easily withstand any load. It is also resistant to abrasion.
- Hygiene - a feature of the material is that it is not able to absorb microorganisms that accumulate in the oral cavity. Due to this, dentures are easy to clean, and this does not cause any difficulties.
- Comfort - some inconvenience may occur, but only during the period of getting used to. The rest of the time they are almost invisible, as if their own teeth.
- Compact - due to the special design of the prostheses, the sky does not completely close, and most remains open.
- Natural teeth remain unharmed - thanks to the shape of the prosthesis, healthy units are not used and they remain intact. In addition, when fixing products, there is no need for turning the supporting teeth.
- Safety is a pretty important plus of the acetal prosthesis. And since wearing prostheses does not cause allergies, everyone can put them on, regardless of age.
- Flexibility - thanks to this, the products fit more tightly to the palate and gums, and due to this, the fixation is more reliable than other analogues.
- Light weight - achieved due to the lack of metal parts of the prosthesis. That is why the wearing of the prosthesis is not only comfortable, but also inconspicuous.
- There is no risk of galvanosis - again, due to the absence of metal parts in the prosthesis, such a phenomenon as galvanism (the occurrence of galvanic current in the oral cavity) can be avoided.
When wearing prostheses made from any other material, patients can often feel the taste of metal in their mouths. They also receive complaints of headaches. Those who chose acetal prostheses do not experience such inconvenience.
Disadvantages of acetal removable dentures
However, it is not yet possible to completely create the ideal prosthesis, which would have only one pluses. Therefore, such a positive product in many ways has its drawbacks. And above all, this concerns the flexibility of the material. Compared to metal, it bends harder. This is both a virtue and a disadvantage at the same time.
Yes, the prosthesis is more dynamic, it is easier to fix and takes root more quickly in the oral cavity. But at the same time, the design is less stable than metal, so it wears out faster.
Another disadvantage is fragility. However, any removable product is just a temporary measure. Typically, the life of such orthopedic structures is from 5 to 8 years.
This is largely due not to their breakdown, but to thinning of bone tissue. There is no way to avoid this, and over time a gap appears between the teeth and this structure. In this case, the metal structure can be corrected, and the upper acetal prosthesis (or lower) will have to be completely replaced.
After a certain period of time, acetal teeth lose their luster, which becomes more noticeable in the light.
Who can put acetal prostheses on?
Before dentures made of this new material are installed, the dentist needs to determine whether they are suitable for the patient according to certain indications. These include the following cases:
- Partial or complete loss of dentition elements.
- Implantation is not possible.
- Chronic periodontal disease.
- As a temporary prosthetics (while an implant is being done).
- Allergy to many prosthetic materials.
In addition, the use of these orthopedic structures allows you to correct the bite if it is broken slightly.
Contraindications to the procedure
In some cases, it is recommended to refrain from installing acetal dentures and for this reason:
- Big loss of dentition. The installation of such prostheses requires at least 5 healthy supporting teeth.
- Atrophy of the alveolar bone. In this case, a removable prosthesis will only aggravate the situation.
- Malocclusion is more pronounced.
- High sensitivity of soft tissues. Due to the pressure exerted by the base of the prosthesis, sores may occur.
- Low crown height.
Before performing such a procedure, any dentist should carefully examine the patient's oral cavity to identify the above symptoms.
And if they are present, the installation of the prosthesis is impossible.
Manufacturing technology
Acetal production of dentures is associated with certain difficulties and therefore only a highly qualified specialist is able to produce the correct design. Responsibility lies with the dental technician and the orthopedic dentist.
The whole process of manufacturing acetal prostheses can conditionally be divided into several stages:
- First, the dentist needs to study the patient’s clinical chart, comparing possible risks. The installation of the prosthesis is possible with a completely healthy oral cavity. In this connection, it is necessary to pre-treat the existing diseases.
- If everything is in order, special materials are used, with the help of which impressions are made from both jaws. This takes into account all the anatomical features of the patient.
- Then, gypsum is poured into the prints to obtain a complete model of the jaws. They serve as the source for the next steps in the manufacture of a removable prosthesis. At the same time, their wax models are placed in place of the missing teeth.
- Plaster models are placed with special equipment in accordance with the anatomy of the patient's oral cavity . In this form, the model is sent to the technique.
- Now the wax rollers are removed and artificial teeth are put in their place.
- Now the model is finished, and you can proceed to the manufacture of acetal denture. It is carefully adjusted to the model, if necessary, polished.
After all these manipulations, the prosthesis is tried on by the patient, if necessary, an adjustment is made. After that, the completely prepared prosthesis remains with the new owner.
Care Rules
Special care for the acetal prosthesis is not required and can be worn for several days. But at the same time, it is necessary to pay attention to him - regularly carry out hygiene procedures. And, despite the fact that the teeth are artificial, they also need it.
To do this, use a low abrasive toothpaste. In the event that it is impossible to clean the mouth after each meal, rinse aid should be used.
Judging by some reviews of acetal prostheses in many forums, in some cases bad breath may occur, plaque appears. In this case, it is necessary to purchase a special tool for the care of removable dentures. At least once a day, it is recommended to remove the structure for half an hour, placing it in a special cleaning solution. This is done so that the prosthesis does not change its color. Also in this way you can remove the remaining microorganisms and clean them in hard to reach places.
These elementary measures will help to preserve the service life of products and protect against the appearance of complications. In addition, to perform them is not difficult for the patient.
Addictive to new teeth
The issue of getting used to prostheses is more acute than ever for most people. During the first days, it is better not to include solid foods in the diet. And as noted above, many people get used to these prostheses in a fairly short time. In most cases, such a rehabilitation period lasts several weeks.
But there is one snag, although to someone it will seem not so significant. As reviews also note, an acetal denture can move slightly during a meal.
For the period of addiction, it is necessary to chew food thoroughly, to read aloud. From healthy nuts and seeds it is better to refrain for now. And to avoid pain (this sometimes happens), massage with gentle pressure should be done. To do this, you can use a toothbrush or massage with your finger. If your mouth is dry, you need to consume more fluid.
Issue price
The cost of acetal prostheses is not much different from other analogues. For such products will have to pay 25-30 thousand rubles. A more accurate bag depends on the clinic the patient is contacting, as well as on the number of lost teeth. Indeed, the more complicated the prosthesis is in manufacturing, the greater the amount of time it will take, and accordingly, it will cost more.
The price of acetal dentures includes all ongoing work, with the exception of the procedure for the rehabilitation of the oral cavity. If a person has any dental diseases, they are paid at a separate rate.
Reviews
Despite the fact that orthopedic products in dentistry appeared relatively recently, they are already full of feedback from doctors and patients. Moreover, most of them are in a positive way. As many patients note, adaptation to new teeth is quite quick and they did not have any difficulties in care.
Clamers made of acetal are very difficult to notice when a person smiles, in connection with this, more and more patients choose such designs. Even if you look at the photo of the acetal clasp prosthesis in full detail, you can hardly notice the difference between artificial teeth and natural ones.
Conclusion
In some cases, removable prosthetics is the only way to return a lost smile. Modern dentistry is constantly being improved and new technologies and materials appear from time to time. Who knows, maybe in a few years there will be a worthy replacement for acetal, which, in turn, has become almost the best alternative to other analogues.
