If we look at official statistics, almost half of the residents of our country by the age of 65 are faced with the problem of complete loss of teeth. In medical practice, this phenomenon is called adentia. This situation should not be ignored, since edentia is not just an aesthetic defect that can cause psychological discomfort in the patient and affect self-esteem. Losing teeth is dangerous because it triggers a series of more serious health problems: the process of grinding food worsens, which leads to dysfunction of the digestive organs, impairs intestinal function, and as a result, the functioning of all internal organs is disrupted.

The most progressive methods of restoring lost teeth are prosthetics on implants or the use of removable structures. Despite all the visible advantages of implantation, this method also has significant disadvantages. It may not be suitable for patients because it requires surgery, which may be contraindicated. And the second significant point is the high cost of all manipulations. An alternative, universal and suitable method of prosthetics for completely edentulous patients is the production and installation of removable orthopedic dental structures.

Removable dentures are distinguished by the fact that they can be removed and put on independently, at any time, without the involvement of specialists. There are two types of these structures:

• partially removable dentures;
• complete removable dentures.

Indications for use

As a rule, complete removable dentures are indicated for defects in a number of teeth, such as complete loss of chewing teeth. In addition, the pathological condition of the periodontium may be an indication. Severe periodontitis requires the installation of such structures; this will be the best solution for patients with this disease. The choice of the type of prosthesis depends on the specific case; the decision is made by the doctor together with the patient, based on a thorough examination of the oral cavity.

Features of implants for chewing and anterior teeth

Implantation of chewing teeth is carried out taking into account the increased chewing load on them. The artificial root is selected individually. However, when restoring lateral units, it should not be short and thin.

Implants are produced:

• lamellar (used in case of bone atrophy);
• root-shaped (implanted into bone tissue of sufficient volume);
• combined.

According to the type of construction for molars, the most reliable titanium rods are of the following types:

• endosseous (intraosseous);
• subperiosteal (implanted into the alveolar process);
• intramucosal (part of a removable denture);
• endodontically stabilized (extend the root system by 7 and 8 units).

Implantation of frontal units involves focusing on the aesthetic result, since the incisors are practically not involved in the chewing process. Therefore, the strength requirements for implants are not so high. They are selected taking into account the following characteristics:

1. Maximum biocompatibility of the material with jaw structures.
2. The length should be within 10 mm.
3. Small diameter. This indicator ensures the implantation of the rod with minimal damage to nearby tissues, which is also significant for the aesthetic result.

Types of removable dentures in complete absence of teeth

If there are no teeth left, the choice of design is significantly limited. Modern medicine offers the installation of prostheses on implants - this is the most reliable and most aesthetic method, but it is not available to everyone due to its high cost and indications. In this case, plate dentures remain - they are suitable for people of any age, if there are no allergic manifestations to the material used to create them. In the absence of teeth, all structures are similar in structure, but can be made of different materials. Let's decide what the pros and cons of different options are.

Plate dentures

Plate dentures, as the name implies, are a plate of different sizes. It acts as the basis of the structure, its basis. Fixing elements and artificial teeth are attached to it. Previously, such dentures were made exclusively from hard materials, but today dental technicians have a wider choice. This allows you to select products individually for patients, based on their needs and financial capabilities. But here it is necessary to remember that the material affects not only the comfort of wearing a denture, but also its service life.

Soft plastic dentures

Thus, acrylic products are considered the most durable. But since they are not always comfortable to wear, the formula of the material has been refined and improved. Complete removable dentures made of soft plastic were born. They are a combination of acrylic with the addition of additional components (for example, diamond chips). Their service life is very impressive, but due to their more plastic structure, they do not injure the gums, do not rub, and provide a tight fit.

Acrylic dentures

This type of prosthesis is the most popular - it is characterized by low price, aesthetics and ease of use. It consists of a base that covers the alveolar process and the body of the jaw, and artificial teeth attached to it. Before installing such a prosthesis, as in other cases, the oral cavity is first prepared for prosthetics, loose teeth are removed and the mucous membrane is treated, and then an impression of the jaws is made. Based on the impression, a primary model is created in the laboratory, which is adjusted and corrected after fitting. Acrylic or plastic prosthesis has the following advantages:

• an affordable way to completely restore teeth;
• ease of use;
• durability (7-9 years with proper care);
• uniform distribution of chewing load;
• quick adaptation period;
• lightness of the material, comfort of use;
• aesthetics and the ability to create a prosthesis that perfectly matches the color of natural gums;
• possibility of repair and correction;
• quick installation.

However, in order to decide which prosthesis is best to choose, you should know not only the advantages, but also the disadvantages of each type of design. For acrylic dentures, this is the possibility of an allergic reaction to the material, trauma to soft tissues during use, bad breath (acrylic is a porous material, bacteria can multiply in it), partial loss of taste, increased gag reflex, temporary impairment of diction and frequent need for correction. Most of these negative effects go away as you get used to the prosthesis, but some you have to put up with. To complete the adaptation period as quickly as possible, do not remove the denture at night.

Nylon dentures

The products are made from pink nylon, which is elastic and durable. They are similar to plate acrylic dentures, but differ from them in some parameters. This design perfectly imitates the gum and part of the alveolar process, it holds well and is suitable for sports enthusiasts. Such dentures are not removed at night even after the end of the adjustment period. A nylon prosthesis has the following advantages:

• hypoallergenic;
• high aesthetics;
• reliable fixation;
• low porosity, and, as a result, the absence of bad breath even after long-term use;
• flexibility, elasticity, comfortable use;
• durability (about 5 years);
• rare percentage of breakdowns.

The disadvantages of this type include the need for care of the prosthesis with the help of special means, the inability to repair in case of breakage, possible bone atrophy and mucosal injuries with prolonged use, uneven distribution of the chewing load (the flexible frame prevents this), the need for frequent correction and relatively high price.

In case of complete absence of teeth, implants are used to better fix the structure, and a metal arch is often used, which enhances the strength of the base. Thus, nyl dentures resemble dentures with a metal base and become even more durable.

Silicone prostheses

They are similar to nylon, but very different from them. Silicone is translucent; artificial – most often plastic – teeth are attached to a base made of it. Silicone dentures, as a rule, are used as temporary ones, because large gaps form between the teeth over time, and the service life of the structure is no more than two years, and it is rarely used for complete dentures. Their advantages:

• natural appearance;
• no allergic reaction;
• lightness and compactness;
• good fixation;
• softness of the material.

With prolonged use of the structure, atrophy of the alveolar bone and subsidence of the gums are possible, which is its significant drawback. In addition, they provide poor distribution of the chewing load and are difficult to maintain.

Clasp dentures

Clasp-type structures are practically not used in cases of complete edentia, since for strong fixation it will be necessary to create supporting surfaces. This requires additional time and financial expenses.

How a partial denture is attached to the jaw

There are 3 options for fastening removable structures: hooks (clasps), locks (attachments), telescopic crowns.
We propose to consider each of the options in more detail. Clasps. They are hooks made of metal or plastic that grip healthy teeth and fix the orthopedic structure in the mouth. The disadvantage of such fastening is poor fixation and unsatisfactory aesthetics. Despite the fact that the hooks are covered by the lip, they are visible to others when smiling and talking.

Attachments. More preferable from an aesthetic point of view. The special lock consists of 2 parts. One element is built into the base of the prosthesis, and the other is attached to the crown that covers your own tooth. This fastening option has a more reliable fixation and gives the product stability. In addition, the attachments distribute the chewing load more evenly, which slows down bone atrophy by almost 2 times.

Telescopic crowns. Presented by a system consisting of 2 crowns. The inner one follows the contours of the ground tooth. The outer one is connected to the base and restores the shape of the tooth. This allows the prosthesis to be securely fixed and prevents it from moving. The possibility of installing a telescopic structure in each specific case is determined by the doctor, since grinding of a large layer of hard tissue of the supporting tooth is required.

Pros and cons of complete dentures

Such designs are very popular; they have many advantages, including:

• Strength and elasticity . Prostheses are comfortable to wear, suitable for patients of all ages and safe. They are made according to an individual impression.
• High aesthetics . It is possible to choose the shape and color of teeth and gums as close as possible to natural ones. All this is selected on an individual basis.
• Easy to care for . Such structures are easy to care for; sometimes you just need to rinse them in running water.

The disadvantages include the following features:

• relatively long adaptation period;
• insufficiently stable fastening;
• feeling of discomfort when laughing, coughing or eating;
• not very long service life;
• food restrictions;
• violation of speech functions;
• the need for preventive regular examinations by a doctor.

Preparation for prosthetics

An important role in the manufacture of high-quality, comfortable designs is played by preparing the patient for prosthetics. The doctor conducts a detailed examination of the oral cavity, identifies individual structural features of the maxillofacial apparatus, and determines the characteristic features of the jaws. At this stage, the material for creating the future structure, the optimal shape, size and color of artificial teeth are selected.

Individual spoons are used. The composition of the mass for impressions is also selected personally. Based on the casts, a model of the jaws is made.

The finished product is made from wax or plaster models. This is quite painstaking work and is carried out using special equipment. In this case, it is important to clearly maintain the distance between the teeth, the depth of their fixation, inclination and many other parameters.

When trying on dentures, the dentist identifies possible nuances that prevent a tight fit. All comments are sent to the laboratory, where a dental technician adjusts the design.

False upper jaw and false lower jaw: what are the differences?

If we are talking about clasp dentures or a removable jaw on implants, then the differences are small - except perhaps the shape of the frame and artificial teeth. If the patient is fitted with a classic complete denture, the upper denture has an artificial palate with suction cups, which helps fix it in the oral cavity. Some people believe that the upper artificial jaw holds up worse than the lower one, but this is not true. The lower jaw does not have such a large area of ​​mucous membrane: the prosthesis is fixed using suction cups and a special cream, but still the risk of prolapse in the lower false jaw is much higher.

Manufacturing of complete removable dentures

The manufacturing process of both acrylic and nylon removable dentures occurs in several stages: taking impressions of the gums, casting a plate, welding teeth to it, and fitting the dentures to the patient’s jaws.

Acrylic dentures are produced by injection molding, and nylon ones are produced by hot injection under pressure. The latter method requires expensive modern equipment and qualified specialists who can work with such equipment. This has an impact on cost, and therefore nylon dentures are much more expensive than acrylic ones.

Why is it necessary to build up bone tissue and do a sinus lift?

Often with edentia there is a lack of bone mass. The longer the space in the jaw is empty without proper load, the more active the atrophic processes are. Volume can be restored through bone grafting. This is an effective procedure aimed at creating a reliable foundation for a titanium rod. It is indicated for:

• bone atrophy;
• loss of tissue due to periodontitis (inflammatory process of the structures that support the tooth);
• deterioration of bone condition after injury.

More often the problem occurs in the upper jaw. This is due to the peculiarities of the anatomical structure. A significant part of the bone in the upper row is the maxillary sinus. The sinus lift technique allows you to restore the missing volume. The procedure is carried out if:

• bone structures have decreased in the area of ​​the alveolar process;
• there is a loss of thickness due to the anatomy of the jaw.

Care and storage

Dentures must be periodically removed from the mouth and cleaned. It's great if you do this every time after eating, but if this is not possible, you can rinse them in the morning and evening. Full dentures can be left in your mouth overnight, but it is best to remove them to give your gums a rest. In this case, before putting it in a special box, you need to thoroughly clean the prosthesis - rinse with boiled water, treat with an antiseptic solution or brush. It is recommended to have it professionally cleaned twice a year.

There is an opinion that the prosthesis should be stored in water or in a special solution. This is not so - a similar method was suitable for rubber prostheses, but modern technologies have made it possible to move away from it. Now it is enough to wrap the prosthesis in a cotton cloth and put it in a special box, where it will be protected from the sun, mechanical damage, heat and chemical influences.

How much will it cost on average in Moscow?

The cost of implantation in different clinics is determined individually, taking into account:

• volume of planned work;
• materials used, medications;
• diagnostic procedures;
• the patient's wishes regarding aesthetics.

Let's give the average cost of dental implantation services in Moscow clinics.

Cost of complete removable dentures

The cost of services is determined individually for each patient, since the individual characteristics of the patient’s oral cavity play a key role in the manufacture of structures. Factors such as the anatomical structure of the maxillofacial apparatus, the chosen type of structure, the material of its manufacture and methods of fixation, the shape and color of artificial teeth are taken into account.

Denta Labor dental laboratory produces complete removable dentures of excellent quality. Our laboratory has created all the conditions to produce high-quality prostheses with a long service life. You can check prices for removable dentures by phone +7 (495) 162-08-25.

Promotion! When paying in advance the full cost of making the prosthesis, the cost is reduced by 2000.

Lifespan of removable partial dentures

Practice shows that the service life of removable plate structures is on average 3-5 years, after which the structure has to be changed. Bugel products have a longer lifespan - up to 5-7 years.

In general, the duration of wearing depends on several factors:

— the quality of the design and the professionalism of the specialist who carried out the installation;

— characteristics of the body and the condition of the oral cavity, the presence of gum diseases and deformation of the dentition;

— accuracy of compliance with doctor’s recommendations and proper home care.
