Unfortunately, not everyone has access to modern dental treatment techniques and the latest materials. Not everyone has the opportunity to install implants. Therefore, today one of the sought-after areas in dentistry is removable prosthetics: full or partial.

Types of removable dentures
Partial removable dentures
If a certain number of teeth remain on the patient's jaw, then partially removable prosthetics are used. In this case, the prosthesis rests not only on the gum, but also on the remaining teeth.
Such designs are made. from nylon and plastic, as well as using a metal frame.
Complete removable dentures
Made for the jaw, in which teeth are completely absent. They rest on the upper jaw on the sky and on the gum. Due to the fact that the teeth are missing, such constructions are not recorded very well. A removable denture can be traditionally made of nylon or plastic.
There are complete removable designs that are called cover or semi-removable. Due to the fact that before their installation in the jaw implanted mini-implants, improved fixation of such prostheses.
Pros and cons of removable dentures
Plastic constructions
This type of denture is used with partial or complete absence of teeth, and is made of acrylic plastic.
-
If the patient completely loses the teeth, the prosthesis will rest on the gum. If the design is made correctly, then when it is put on between the prosthesis and the mucous is created empty space (effect of suctionability), due to which the prosthesis is held. - In the presence of a certain number of teeth, the structure is held by a hard wire clasp, which encircles the abutment teeth.
- With the loss of one or two teeth and the patient's unwillingness to implant implants or grind healthy teeth to support, dentists suggest dental prosthesis. It is invisible in the mouth and worn unlimited time.
Acrylic removable dental structures tested by time, easy to use and have no contraindications. Wearing them is recommended for three to four years. However, this period can be extended to five years, in case the patient has delayed atrophy of bone tissue.
Minuses:
-
Due to a plate that completely covers the sky, the installation of an acrylic construction can lead to a partial loss of taste. - Due to the low strength of the plastic inset jaw, it is unsuitable for chewing solid food.
- Monomer, which is part of acrylic structures, can cause inflammation or burning sensation in the oral cavity.
- In order to provide a more reliable fixation of the artificial jaw, it is sometimes necessary to dissect and close healthy teeth with metal crowns.
- To carry out the correction can not do without regular visits to the dentist.
Nylon designs
Constructions of this material, which are made of soft plastic, are quite elastic. They are attached by the effect of suction and do not have metal parts.
-
Grinding of abutment teeth is not required due to the special method of fastening nylon artificial jaws. - A more reliable fixation of the artificial jaw is provided with the help of gels and creams.
- Plastic hooks are invisible during a conversation.
- Nylon prostheses are used in the absence of one, the entire range of teeth or their defects, as well as in the presence of inflammatory diseases of the gums.
- Despite the fact that the construction of this material is elastic, it has sufficient strength.
- Since soft plastics are used to make an artificial jaw, the gums are not irritated.
- Nylon prostheses can be matched to the color of natural tooth enamel.
- The service life of such a removable jaw is from five to seven years.
Minuses:
- When wearing this type of design may develop atrophy of the alveolar process of the jaw.
- Food of high hardness is chewed poorly.
- The load on the jaw, in the process of chewing food, is distributed incorrectly.
- Due to the fact that the design can sag, for its correction is required to regularly visit the dentist.
- Clean nylon prostheses only with special products.
- Patients are not recommended to use foods with high acidity and hot meals, drink coffee and strong tea.
- The price of dental structures made of nylon is about one and a half times higher than the clasp.

This type of construction is attached with hooks, so the presence of teeth in the mouth is required. With their absence, it will be necessary to install implants.
-
Modern dentistry allows do byugelny dentures without the sky. It is the most convenient to use and aesthetically attractive. - Depending on the structure of the dentition and financial possibilities, there is a choice of fixtures.
- Byugelny designs can be established even in the presence of inflammatory diseases of gums or defects of teeth.
- They do not need to be removed often.
- They can serve from five years and more.
- And most importantly, when compared with other removable dentures, this is an affordable price for removable denture dentures.
Minuses:
- After installing the bugel constructions for a long time, a metallic taste may be present in the mouth.
- When installed on the front teeth, the fixing hooks will be visible, which violates the aesthetic appearance.
- The cost of the prosthesis increases when choosing on it more perfect and convenient designs.
Implant Prostheses
They are best used. in the absence of teeth, because prosthetic suction cups leave much to be desired. Removable jaws with the effect of suction can become detached from the jaw, as a result of which it becomes uncomfortable to chew food and diction is disturbed. Therefore, designs have been developed that improve the fixation of dentures. This kind of construction is called - covering dentures and has several options for prosthetics.
1. On intracanal implants
- Teeth remaining in the oral cavity, cut down under the root.
- Dental canals are filled.
- Implants are screwed into the root canal with a metal head protruding above the root.
- On the internal projection of the structure, recesses for these heads are cut and retaining matrices of silicone are inserted.
Such a removable jaw is held securely, and bone atrophy slows down. Due to this, the service life of the structure increases.
2. With locking beam type
-
Several implants (at the discretion of the dentist) are inserted into the jaw, between which a metal beam is made. - A recess is cut on the inner surface of the structure, which must exactly match the size of the beam.
- Silicone matrices are inserted into the recesses, which tightly embrace the beam and firmly fix the prostheses.
3. With push-button type lock
- Several implants are implanted in the jaw.
- Attachments with a protruding round head are screwed into the implants.
- Under attachments on the construction, recesses are cut, and silicone dies are inserted (locking mechanism). Due to this, the artificial jaw is held securely.
Prices
The price of dental constructions depends on the material from which they are made. The cost of acrylic prostheses is somewhat cheaper than nylon structures that are made abroad. Basically, the price is completely removable dentures quite democratic, if we compare it with the cost of bridges or implants.
What kind of removable dentures is better
-
If there are some teeth left in the oral cavity, but prosthetics cannot be made with non-removable structures, then the by-piece design is best. - With fully lost teeth, a removable acrylic design is a good option. To improve its attachment to the jaw, you can use implants.
- Patients are not very fond of nylon dentures, although dentists advertise them (making them profitable because of the high cost). Of course, they have great aesthetics, but food, especially hard, is painful to chew on them.
Removable dentures should keep away from chemical and mechanical damage. If any breakages or cracks appear on them, then the constructions cannot be used; it is necessary to immediately consult a doctor. In no case is it recommended to file and grind your teeth. And do not forget to visit the doctor every six months.
