New technologies in dental prosthetics have made it possible to create entire classes of qualitatively different denture structures. The most famous of them are the new palateless dentures, sandwich dentures, acetal, silicone and polyurethane removable soft dentures. New generation fixed dentures include veneers, ceramic tooth inlays, zirconium crowns, adhesive bridges without turning, titanium implants and titanium yoke dentures.
The adhesive strength of modern adhesives and the strength properties of prosthetic dental materials make it possible to preserve the hard tissues of teeth and ensure a long service life of the latest dentures.
Advantages
The main factors determining the popularity of sandwich dentures are the lack of overlap of the palatal area and the ability to wear the system around the clock. The first advantage allows you to preserve the functionality of your taste buds - practice shows that when using other models, up to 40% of their effectiveness is lost, which reduces the ability to fully enjoy a meal. The second advantage is characterized, rather, by a psychological effect - the patient does not need to constantly get used to the newly installed system, as well as accustom himself to the nightly removal of the structure, which causes awkwardness and embarrassment for those who do not live alone.
In addition, among the positive aspects of sandwich systems it is also worth noting:
- No need to prepare supporting units;
- Fixation without the use of aesthetically unattractive hooks and adhesives;
- Affordable price compared to implantation, as well as production speed;
- Strength and reliability of structures.
Price
The price of a complete removable denture in this category depends on the materials used for its manufacture. The cost range varies from 45 to 60 thousand, and additional costs associated with the examination and treatment of identified pathologies must be taken into account.
Indications for installation
The main recommendation for the use of sandwich dentures is the need to restore the integrity of the dentition. Today, this technique is not the only available method - all other things being equal, implantation still remains the more preferable option. However, in some situations the integration of artificial pins is not possible, and then the advantages of using such models come to the fore. Factors that contribute to a decision in favor of Sandwiches include:
- The patient’s desire to maintain taste;
- Detection of an enhanced gag reflex when the prosthesis comes into contact with the palatine lobe;
- Anatomical structure that eliminates the effectiveness of using suction cups and glue;
- Sensitivity of gum tissue, contributing to the development of pathologies.
The technology does not provide for age restrictions for the installation of removable sandwich dentures without implantation. The only mandatory condition is the presence of at least two of its own immobile units or healthy roots.

As mentioned above, fundamentally new properties associated with the characteristics of the latest materials in dental prosthetics have fully affected such structures as:
Zirconium teeth
- Zirconium is actively used for crowns and bridges, root inlays, abutments, and implants. Due to the absence of metallic shine, this material makes the most aesthetically pleasing and durable dental bridges and abutments.
Pressed ceramic veneers, inlays and crowns
- With the help of pressed porcelain and 4th generation adhesive systems, a revolution has occurred in dental microprosthetics. Veneers, lumineers, restoring ceramic inlays appeared.

In addition to excellent strength and high aesthetic performance, the latest dental prostheses have a long service life and practically do not cause allergies.
How it is made
The manufacturing process of a denture of this model is very complex, so the devices are used only in high-level clinics.
The production of the prosthesis is carried out in special laboratories, according to a previously made impression of the jaw of the patient who is undergoing the procedure of replacing teeth with prostheses. The technology for performing the process is unknown, since it is protected by a patent and has not been declassified. After the design is made, the patient is invited to the dentist for a fitting.
During the visit, the finished product is tried on for the patient. If shortcomings and inconveniences in wearing the design are found, it is sent for revision. If the design is ideal in size and shape, the patient is given a form with advice on caring for the dentures to ensure a longer service life.
New generation removable dentures
The new generation of partially removable dentures are made of flexible materials that have certain advantages:
- It's easier to get used to them
- They are lighter than acrylic counterparts
- Do not cause allergies
Thanks to the flexibility of the base, the patient has the feeling that he has “removable teeth that are soft and very comfortable,” or in other words, soft dentures.
Separately, we need a new generation of removable dentures, the price of which in Moscow starts at 30,000 rubles. Structurally, it is a combination of removable silicone crowns connected to a base on which acrylic teeth are located. It is held on the gums by removable crowns, which are placed on your own remaining teeth.

At the same time, almost every new generation nylon denture, the price of which is almost twice as high as its acrylic counterparts, is less durable and is most useful within 6-12 months. Due to the soft base, polyurethane and nylon removable structures contribute to accelerated bone tissue atrophy. This leads to the disappearance of the suction effect with complete edentia on the upper and lower jaw after 6-8 months. If this kind of structure holds on to the patient’s remaining teeth, then the periodontal retaining clasps of nylon dentures lead to bedsores and inflammation around the supporting teeth.
Today, when the technology for installing implants makes it possible to abandon prosthetics using suction cups, dentists recommend using new generation dentures without a palate. We are talking about a bridge-like prosthesis of 12 or 14 crowns, supported by 6 or 8 titanium implants, which are inserted into the upper jaw.
Indications and contraindications
A removable sandwich denture is suitable for anyone who needs prosthetics. However, there are certain indications for which the dentist recommends this particular design .
- Absence of a large number of teeth.
- Standard dentures cause a gag reflex.
- Other orthopedic structures cause allergies due to the presence of metal elements.
- Installation of other structures is not possible due to contraindications (bruxism, epilepsy).
- Clasp systems cause discomfort.
- A person has an abnormal structure of the palate, which prevents the installation of traditional dentures.
- The patient has pathologies of the salivary glands or increased dryness of the oral cavity.
Data from the presentation
The number of contraindications boils down to the following: a sandwich prosthesis is not suitable for people with an existing allergy to any material used to create the product . Situations of an allergic reaction are extremely rare, because the prosthesis is made of neutral plastic.
Also the sandwich is not installed :
- if the supporting teeth are the front ones;
- for serious blood diseases;
- for mental disorders.
New generation dentures, cost
Prices for modern dentures, including removable dentures of the new generation, the cost of which is significantly higher than those made the old fashioned way, depend on a number of factors:
- If you are getting new generation palateless dentures, they cost almost twice as much as standard artificial teeth. For example, the cost of a high-quality nylon or polyurethane removable denture without a palate, with partial edentia, in Moscow starts from 25,000 rubles, and the cost of an acrylic analogue will average about 15,000
- If you want to make zirconium crowns for yourself in Moscow, then their turnkey cost starts from 25-30 thousand per one. The price of a ceramic veneer or a restorative inlay made of pressed porcelain starts from 15,000 rubles.
- In addition, the cost of the latest dental prostheses depends on the availability of the necessary equipment and materials in the clinic, for example, the Cerek milling system.
- Highly qualified dentists and dental technicians are a significant component of the price (up to 30-40%) for high-tech dentures.
Care
Caring for dentures of this type is quite simple: brushing twice a day with a regular toothbrush and non-abrasive toothpaste, rinsing after each meal, disinfecting with special tablets once or twice a week. It is not necessary to remove the structure at night; you can sleep peacefully and comfortably with it. It is recommended to have your teeth professionally cleaned by your dentist once a year.

Markin Alexey Ivanovich. Moscow
Half a year ago, I placed 4 implants on my lower jaw in Kazakhstan, while they were taking root, in this clinic they made me a temporary nylon removable denture. I paid very little for it and wore it for 4 months until they put crowns on the implants. The prosthetist recommended me a good remedy for cleaning gums and crowns, for which I am very grateful to him, thank you.

Question for a specialist
Sandwich prosthesis is a new product in the field of removable prosthetics. In essence, this is a regular overdenture that rests on the gums. However, it differs from similar designs in the presence of locks or attachments that are fixed in the patient’s own teeth, as well as the absence of palatal overlap. Patients note that the sandwich denture is more comfortable and creates the feeling of having their own teeth in the mouth.

The history of sandwich dentures
“Sandwiches” are the development of Russian orthopedic dentists with 30 years of experience in practical prosthetics. The specialists took into account all the comments and reviews of patients wearing conventional removable appliances (poor fixation, rubbing of the gums, loss of the “jaw”, lisp, lack of taste in food and nausea). And as a result, they created a removable dental sandwich prosthesis. By the way, it is called that not because it is edible, but because of a special patented manufacturing technology - when materials with different physical properties are combined with each other in a certain sequence.
Stages of prosthetics - preparation, construction and installation
Let's take a closer look at how a sandwich prosthesis on spherical attachments functions and is installed, as well as how it is manufactured.
At the first stage, the supporting teeth are prepared for installation of the prosthesis. The crown is processed, the degree of tooth mobility, the direction of root growth are assessed, and then the nerve is removed from the root canals (but this is not always necessary) and infectious foci, if any. Afterwards, the root is filled and an oval-shaped cavity is created in it. A root spherical attachment is placed inside it, which protrudes above the gum. It is secured with a special fixing material.
At the second stage, impressions are taken, according to which individual prostheses are created in the laboratory. On average, the sandwich dentures will be ready in 2-3 weeks. It is worth noting that the second part of the attachment (which is located inside the prosthesis) is worked out by the dental technician - it is a recess into which the spherical part is placed, located on the supporting tooth. As soon as the two elements are connected, the mount snaps into place and securely fixes the orthopedic structure in the oral cavity.
At the third stage, the sandwich prosthesis undergoes final fitting. If it does not cause discomfort or put pressure on the gums, then the work is considered completed - the doctor will definitely teach the patient the rules for caring for new teeth, and will also explain how to remove and install the denture independently.
Disadvantages of sandwich dentures
Sandwich dentures also have disadvantages. Firstly, they are somewhat more expensive than traditional removable ones, because their production is more complicated. Secondly, they are not suitable for patients with nervous system disorders, or those with allergic reactions to materials. Thirdly, a “sandwich” can be installed only if there are at least two natural teeth in a row, the roots of which are suitable for fastening. However, there is a risk of damage to the supporting teeth - over time, the roots may simply split into pieces due to excessive stress.
Not a single removable denture, even the most modern one, protects the jaw from atrophy (or loss) of bone tissue in those places where tooth roots were previously located, but now they are not there. Over time, the height and width of the alveolar process decreases, and the level of the gum also decreases - so the “pullers” become uncomfortable, begin to shift, and you have to go to the dentist for correction. Now dentistry can offer only one solution to prevent bone atrophy - implant prosthetics.
Where can such a prosthesis be made?
Where to install a dental sandwich prosthesis? Sandwich structures are manufactured and installed in only one clinic in Russia - the Moscow dentistry "Persona Life". This is where the creators of the patented “sandwich” work. Moreover, the rights to the patent and manufacturing techniques were not transferred to anyone, so the removable “sandwich” is available only to a limited circle of patients living in the capital or having the opportunity to visit it regularly - after all, the prosthesis will have to be adjusted regularly.
