Prosthetics and restoration of their functions plays a very important role for the human body. Lack of teeth does not allow chewing food, which leads to various intestinal and gastric diseases. The impossibility of grinding large pieces of food causes their incomplete assimilation, which does not allow vitamins and minerals to enter the body. Aesthetic appearance is also not the last thing in a person's appearance.
The technology of tooth restoration in recent years has gone a long way. The use of modern high-tech materials allows dentistry to replace teeth from one specimen to a whole jaw row and even with the complete absence of chewing elements in the mouth.

Removable dentures
For the correct type of prosthesis, it is necessary to take into account a number of factors:
- the number of missing teeth in the oral cavity. If one or two are missing, it is worth using the implant implantation technology or performing a conditionally removable denture;
- if desired, to restore the process of chewing food most fully it is recommended to install fixed structuresthey are most firmly seated in the mouth. For this, the possibility of performing a bridge must be present, that is, several teeth must be saved to support the bridge on them. For the possibility of a radiant smile, veneers and products are applied with regard to the removable option;
- For convenience of wearing, stationary prosthetics are used, since completely removable prostheses, no matter how comfortable the product, need to be removed from the mouth from time to time for cleaning. In addition, those areas of the gum bed that are under the greatest load can relax;
- An important factor influencing the choice of how to restore teeth is the material side of the issue. Many patients would like to choose expensive materials and implants, but stop at the best option, which allows them the thickness of the wallet.
The decision on the choice of a denture should not be decided without consultation with an experienced dentist. Such specialists have extensive knowledge and will be able to take into account several important factors in parallel for each individual patient, especially since patient reviews indicate the effect of allergy on components used in dentistry.
Acrylic Dentures
Practice shows that the general public successfully apply acrylic removable dentures. Patient reviews talk about their affordable price, combined with the mandatory set of necessary functions.
The substance, called "acrylic", summarizes the group of thermoplastic polymers, containing acrylic acid, which is produced from natural gas. It appeared for the first time in the 50s of the last century in America, then production began to expand in European countries.
The high popularity of the use of this material in dentistry is due to high wear resistance, ecology, high durability and ease.
Pressing removable acrylic prostheses in the absence of teeth occurs on the gums. Between it and the product creates a rarefied space that allows you to stick to the gums.
Partially removable acrylic prostheses are attached to the remaining healthy teeth. These include dental dental constructions, which for mounting are equipped with clasps. Hooks cover the tooth at the base and allow you to fix the prosthesis, while not completely destroy the tooth enamel.
In the absence of one or two teeth, no need to grind adjacent teeth under the prosthesis. In this case, make a removable product "butterfly" of acrylic. The most popular such type of design for prosthetic molars.
Benefits
- Acrylic, worn in the mouth constantly, does not have any harmful effects on the human body and can be used by patients, regardless of their age.
- Fastening allows you to smile without fastening elements visible from the outside.
- Simplicity and ease of care and wear. Removed and worn in one motion, care does not require the purchase of special pastes and detergent materials.
- It can, if necessary, be made urgently, within a few days.
- A variety of colors and shades of the base material allow you to pick them up to existing teeth without any visible differences.
- During operation, the abutment teeth are almost not affected, since the gums are also loaded with them.
- Dentures available to a wide range of patients due to low prices.
- The possibility of repair in case of cracking or coring crown.
disadvantages
- Due to the conditional hardness of the products, the possibility of pressure wounds is allowed, if the prosthesis is fitted incorrectly.
- Scaling the abutment teeth under the crown, reduces their lifespan, can cause caries and other pathologies.
- Acryl is a favorable environment for the life and reproduction of microbes. This is facilitated by the porous structure of the material and its ability to absorb a small amount of moisture.
- Colored food colors change the hue of the teeth over time, and they lose their attractive appearance.
Silicone Dentures
Silicone belongs to the group of polyorganosiloxanes, which are obtained by chemical transformations of polymers. Found widespread use in dental practice due to new properties that are not enough to create high-tech products. These include immunity and inertness of the material to biological and chemical substances, durability, environmental friendliness, high plasticity and flexibility.
It is not the entire removable denture that is made of silicone, but only its base, in which the teeth are inserted from ceramics or plastics. Fastening to the base teeth occurs with the help of clamps, small and inconspicuous by visual contact.
Silicone Prosthetics often used to restore parts of a range of teethbecause, because of their flexibility, they cannot withstand the full load on the entire jaw.
Recommended for small inserts in the front of the jaw, as they have a very aesthetic look.
Benefits
- Greater flexibility allows rigorous adjustment to the gum configuration and shortens the habituation period.
- Due to the complete repetition of the surface configuration does not drop out in critical situations from the oral cavity.
- Does not cause allergic manifestations of the body.
- Does not require grinding of adjacent teeth.
- The hue is almost identical to the natural color and appearance of your own teeth, the fastening hooks are made to match the color of the gums.
disadvantages
- The flexibility and elasticity of prostheses is an advantage and a disadvantage. Because of this quality, when chewing solid food appears pain in the gums.
- For periodic cleaning of prostheses need to purchase special tools. If you use the wrong drugs, it is fraught with the appearance of an unpleasant smell and a change in shade.
- The use of soft clasps can not fully protect the gums from pressure trauma. At the same time the surface of the gum is flattened and inflammation appears.
- The internal surface of the prosthesis, turned to the gum, is poorly cleaned due to the rough surface, which causes a bad smell. Patient testimonials say that this can be avoided by donating a prosthesis for treatment to a dental office once every two months.
- The high cost of the material and sophisticated manufacturing technology do not allow the mass circle of patients to use silicone dentures.
- The greater the number of teeth in the prosthesis, the more often it needs to be adjusted due to deformation.
Nylon Dentures
Nylon is a polyamide obtained synthetically and approximated by protein properties. As a temporary material for the basis in the dental industry, he became interested in manufacturers in the middle of the last century, but modern high-quality permanent removable structures in dentistry appeared at the beginning of our century.
Nowadays, nylon dentures are increasingly being used for prosthetics. Reviews of patients who have tried this material on themselves are often positive. Material during operation does not absorb moisture, under shock load springs and returns its shape. Extremely flexible and elastic, not prone to abrasion, not an aggressive allergen, retains constant homogeneity throughout the mass.
In general, the statement of dentists about nylon prostheses is very positive. And patient reviews depend on the perception and ability to adapt to the presence of a foreign body in the mouth.
Benefits
- According to their chemical properties and appearance, such structures very close to natural teeth and the perfection of replacement is simply amazing.
- For attachment, flexible and pliable clasps are used, which very gently affect the enamel of the adjacent healthy tooth and do not require their prior grinding. Healthy teeth retain their service life, it is not required to cover them with special crowns.
- If healthy teeth in the oral cavity are affected by periodontal disease or are subject to rapid destruction, the use of nylon prostheses is very reasonable, since they do not affect the adjacent teeth and do not shorten their lifespan.
- In the synthesis of nylon material, no allergenic components are used, which cannot be said, for example, of acrylic prostheses.
- When wearing artificial limbs no evidence to apply for fixing glue in the form of gels, due to the almost complete repeatability of the surface of the gums, the question of fragile fastening disappears by itself.
- The flexibility of the prostheses does not make them less durable. Ease reduces the time of adaptation to a foreign body. The lifespan without destruction, provided the gum bone tissue remains unchanged, is up to 7 years.
disadvantages
- A very careful attitude is required with the daily care of dentures. The use of ordinary toothpastes is not recommended because they contain abrasive particles and may eventually cover the surface of the dental product with a network of tiny scratches and the appearance will be hopelessly damaged. Surface uniformity is disturbed, resulting in a strong odor. This happens because various food liquids begin to be absorbed and a favorable environment appears for the settlement and reproduction of bacteria.
- In the area of the molars, gum destruction often occurs due to excessive pressure. The flexible material of the prosthesis cannot hold the pressure of solid food and the bone can change shape.
- The same danger has the attachment of prostheses with flexible hooks-clasps. Small chewing pressure they withstand with dignity. But when using solid foods in the diet, their deflection occurs and pressure from the prosthesis is carried out on the gum at the base of the tooth. Constantly repeated loading leads to rubbing and inflammation of the oral mucosa.
- Pwhen installing nylon flexible prostheses bone deformation occurs in the gum.This happens practically when using any kind of construction. But acrylic products have a hard base and do not sag, thereby not increasing the load. Nylon prostheses need to be constantly adjusted by the dentist. Sinking of nylon bases was observed about 1 mm per year, therefore, correction of the form should be carried out, on average, once every three years.
- Sagging of prostheses threatens because the clasps start to crash into the periodontal tissue of the tooth and destroy it, which may cause slight bleeding of the gums.
- Poor repair and grinding. When dressing on small teeth, there is sometimes an insufficient fixation and sometimes subsidence.
Reviews
I could afford a denture made of plastic (acrylic). Made completely detachable lower jaw, and the top is mounted on the supporting canines under the crowns. I got used to it for a long time, but now everything is normal and the appearance pleases. I wear two years.
My doctor did not recommend making a large silicone lower jaw. Therefore, it was made of acrylic, and in the upper part they used silicone for four teeth. I clean the lower denture as usual, and remove the upper denture and clean it with a special paste. Fuss a lot, but silicone looks better.
I came to the clinic because I wanted to build a bridge. Having made an x-ray, the dentist dissuaded me, the three front teeth required removal and could not serve as a full support. Therefore me made byugel prostheticsthat suits me completely, as the expert got knowledgeable and did everything right.
