Dentures may be subdivided into several groups and subgroups:

  • Full removable plastic plate prostheses;
  • Partial dentures: plastic plate dentures, plastic plate immediatprotezy, clasp dentures, removable sectors or segments of the dental arches;
  • Conditionally removable prostheses.

Full dentures

Full removable plastic plate dentures are often the only alternative to the prosthetic teeth in the absence of one or both jaws. Dental implants are made of acrylic plastics by injection molding, hot and cold kompressatsionnoy polymerization. Dentures may vary in color, shape and size of the teeth.

Artificial teeth are made using modern technologies, have a very high wear resistance and good aesthetic qualities. With proper use and good health for a long time they do not change their appearance, color, density, and can be used for a long time. In addition, it is realistic to pick up the prosthesis to the individual characteristics and the patient's wishes.

Full dentures, as well, and other removable orthopedic devices is acceptable to leave in the mouth at night after the evening hygiene. If the owner of a removable prosthesis wants to take a break from the prosthesis during sleep, after hygienic cleaning wipe it dry, and wrapped in a napkin or handkerchief, leave until morning.

An alternative to full dentures can be implant prosthetics.

Partial dentures

Partial dentures used when one or more lost teeth.

This type of removable dentures often prescribed for:

  • loss of major posterior teeth,
  • a terminal dentition defects, there is no possibility to use as a support bridge adjacent teeth due to their absence or loosening in the jaw bone,
  • dentition defects large extent,
  • as a temporary prosthesis.

Plastic Plate partial dentures

Designed to restore the lost fragments of the dentition are the most simple and affordable removable prosthetic design. Prostheses of this design based on its basis the gingival surface and held in the mouth by clasps (metal hooks) The end to a defect in the supporting teeth. Wherein the abutment teeth may be covered or crowns to be without those.

Klammer such prostheses are usually made of springy wire stainless steel or precious metal. They embrace the abutment, securely hold the denture in the mouth during a meal and conversation. The retaining clasp prosthesis placed at the base of the tooth and is usually covered lip, a poet almost invisible to others.

Partial acrylic dentures can be made without retaining hooks. In this case they are visually nezamentnye mounting structure called attachments. They can be used in all cases, and only under certain conditions.

Castles (attachment) — a special mounting design consists of two main components working together. One lock element is located inside of the artificial tooth or denture. The second element of the locking fastening is made with a crown, or can be fixed to the intact roots of the teeth that can hold a lot of time removable denture.

Optional mounting attachments for removable prosthesis has a number of advantages, both in terms of aesthetics, and from the point of view of reliability of operation. Fixing locks (attachment), used in the manufacture of dentures are made in a variety of technical options. But their essence is always reduced to a single capabilities and goals — how can you fix the reliability and stability of dentures, they must be relatively simple to maintain and operate.

Currently, dentists do not recommend the use of plastic lamellar dentures as long as it is unsatisfying on terms of effective operation. After a few months, it loses its functional and aesthetic qualities, due to the fact that:

  • Wire clasp (hook to hold) becomes elastic properties after 1-2 month and just hanging on abutment tooth.
  • Typically, such a prosthesis is often made from the cheapest — acrylic set (sets) of the teeth in the occluder — a primitive and obsolete instrument.
  • Through 2-3 months will erase chewing mounds, then washed the body of the artificial tooth, which increases the load on the remaining teeth.
  • By the above-described disadvantages can be added discomfort, pain in the mandibular joint, and headaches.

In modern hospitals artificial teeth in the plate is not removable prostheses made of plastic, ceramic or a composite. Instead oklyudatora used articulator — a complex device that simulates the movement Temporomandibular joint. However, this prosthesis is still considered as a temporary, and after a certain period it is replaced by a more durable.


Immediatprotez— A type of plastic removable partial dentures. Used as a temporary structure after removal of teeth and other temporary situations.

Clasp dentures

Clasp (Derived from the German word "Bugel", which translated means "bow"), partial dentures are more complex and expensive design of the denture. They are believed to be reliable and easy to use. In contrast to the partial plastic prostheses that transmit all the chewing pressure on the gums and the teeth are just holding element clasp prostheses evenly distribute the load between the gingival surface of the jaw and remaining teeth.

In the manufacture of partial dentures in a dental laboratory made a precise calculation and simulation of all bearing and fastening elements of the future prosthesis. The basis clasp prosthesis is a metal frame — arc with all fixing, fixing and functional elements, on which is located a plastic base with replacing defective artificial teeth. The metal frame clasp prosthesis is always individual and manufactured by casting of super hromokobaltovyh, titanium or gold: platinum alloys. Durability metal can minimize the thickness, volume and total weight of the prosthesis. Immediately arcs connecting the right and left sides of the clasp prosthesis are usually located in special areas of the mouth, without creating discomfort for its owner.

Clasp dentures, as well as partial acrylic dentures can be attached to the teeth and locking clasp fastenings (attachments). But unlike the plastic prosthesis in which the attachment is used somewhat limited modification to the clasp locks can be used simply with a fantastic technical solution that gives clasp prostheses true versatility, comfort and aesthetic possibilities of recovery in any areas of the teeth.

When using a partial denture abutment teeth with clasps shut recommend crowns. When using attachments abutments necessarily closed crowns. As the clasp is not just holding on to the abutment, and redistributes it an essential part of chewing pressure, closed two crowns or, more commonly, three teeth from the end dentition defect.

Clasp prosthesis can be made in almost all cases, the partial loss of teeth. These implants are used as therapeutic and Immobilizing, splinting devices with increased mobility of the teeth and periodontal disease.

Dentures on telescopic crowns

Dentures on telescopic crowns are a type of partial dentures. They are retained on the tooth crown by consisting of two parts. The first part is the actual metal-ceramic crown and removed. The second portion — the metallic cap is cemented with parallel walls on the tooth. How folding telescope, the crown sits on one another, tightly holding on to her.

The same principle can be manufactured and removable bridges. They are needed in those cases where a large prosthesis needs not to be fixed.

According to scientific literature, telescopic crowns on teeth is much inferior to the longevity of prosthetic implant. Therefore, this kind of dentures are made in dental clinics often.

movable sectors and segments of dentition

In practice, dentists are cases unilateral loss of posterior teeth on one or both jaws. In such circumstances it is possible to manufacture artificial denture clasp teeth arranged on one side only. But because the clasp provides primarily a metal arc draped on the opposite side jaws, the arc attachment side where all teeth are stored and also not covered by crowns, it is often problematic.

In such situations, make unilateral prostheses made — removable sectors or segments, which are also attached clasps or attachments. If the far chewing tooth is missing, ie, terminal attaching defect, the segment is attached to the removable support by locking teeth only.

Conditionally removable Prostheses

Conditionally removable Prostheses produced in the absence of one tooth. More often it is the loss of posterior teeth. Artificial tooth in the prosthesis can be made of plastics or ceramics. Hold it on the adjacent teeth supporting the metal legs just bow and follow the contours of the abutment teeth. The support elements may simply be glued to the tooth or dropped into the preformed grooves with additional fixing light-curing composite material.

These dentures very well help out at a loss, for example, six teeth. These single pasted teeth can not be a very long and therefore require periodic audit by the doctor. If necessary, they are removed and re-stick. Patient such as dentures themselves should not be removed and, probably due to this fact, this type of prosthesis is called conditionally removable.

All existing types of removable dentures differ from permanently fixed bridges that need to be removed independently, as they lie on the surface of the gingival jaw and thus create badly washed zone. Recommended to remove the prosthesis after a meal to rinse the surface of the denture base, adjacent to the gum. Also, the mouth is rinsed and then the prosthesis is replaced at the next meal or before the evening or morning hygiene and brushing.
