Dental health is not only aesthetically important, it is also very important for the absence of pathological processes in the internal organs of a person. If the chewing function is impaired, the organs of the gastrointestinal tract suffer. With developing caries, a person can not only bring an infection into the body, but also lose some teeth, which entails new problems, for example, the selection of prostheses.
What are dentures on the jaw for?
Defects in the dentition are very diverse, and their elimination requires an exclusively individual approach to each person. The dentures on the jaw are installed according to certain indications, in order to make life easier for patients of dentists. In what cases can removable clasp prostheses become the optimal solution?
The advantages of clasp prostheses
Clasp prosthesis is considered to be one of the best ways to prosthetics with partial loss.
- In most cases, the clasp prosthesis does not require the preparation of the patient’s teeth.
- Clasp dentures on the upper jaw have a relatively small (in comparison with plate, acrylic or nylon mucosal overlap area.
- Individual and high-precision casting of the arch of the clasp prosthesis allows you to make prosthetics as reliable and convenient as possible. The materials used (chromocobalt alloy, gold, etc.) meet all modern strength and hygiene requirements.
- A wide variety of supporting, holding, supporting-holding and other clasps allows you to plan the design of the prosthesis in order to minimize pressure on the mucous membrane and slow the atrophy of the tissues of the oral cavity, while achieving the best fixation of the product.
- Planning the design of the clasp prosthesis is an individual and creative task. But with a successful solution, the prosthesis is made taking into account the location and inclination of the teeth of each individual patient with the choice of the optimal route of administration and application of the product.
- In the presence of increased mobility of the remaining teeth, arch prostheses on the upper jaw can partially perform splinting functions, prolonging their service life.
- The addiction to clasp dentures comes faster and easier in comparison with the plate analogue.
Clasp prosthesis fixation
The main means of fixing the clasp prosthesis is clasps (special processes of the cast metal frame superimposed on the natural anatomical recesses of the teeth or covering them from the side surfaces). They not only hold the prosthesis in place, but also do not allow it to move in the horizontal and vertical directions during conversation and eating. Support clasps are also able to partially transfer chewing pressure to their own teeth, which is more natural than to the mucous membrane. Thus, they help to avoid the additional risk of gum injury and increase the chewing efficiency.
Clasp dentures on the upper jaw are additionally fixed with a flat metal arch adjacent to the mucous membrane of the palate. This function is especially pronounced with bilateral loss of several extreme chewing teeth.
In case of insufficient clamping of the prosthesis with clasps, additional measures can be applied. Most often, doctors recommend lubricating the inner surfaces of plastic elements directly adjacent to the mucosa with special adhesive creams. This not only improves fixation, but also prevents food from getting under the prosthesis.
Indications for the installation of clasp prostheses
- Included defects of the dentition limited by natural teeth on both sides (both single and multiple).
- Unilateral and bilateral end defects.
- Any defects in the dentition, aggravated by periodontal diseases of preserved teeth.
- Defects in the dentition, combined with significant atrophy of the alveolar processes of the jaw in the toothless areas.
Castle clasp prostheses
A special kind of removable products of this type is a clasp clasp prosthesis. Its peculiarity lies in the presence of a special fixing device - a lock, rigidly attached to an artificial crown on the abutment teeth. Such locks can be of various shapes and designs. So, some work on the principle of a latch, when combining two parts of the lock, the prosthesis receives a reliable fixation regardless of the shape of the retaining teeth, which is very important when using clasps.
Another type of locks requires the introduction of an additional locking element, removed by the patient using a special device. This is necessary for daily extraction of the prosthesis for hygienic care. Despite the relative difficulties of this type of locks, they provide the most reliable and comfortable fixation.
The disadvantages of this method of prosthetics
- The complexity and accuracy of the prosthesis. High-precision casting and the presence of diverse structural elements require great qualifications from all employees of the dental clinic: doctor, technician and foundry.
- Duration of manufacture and the need for several patient visits. In addition to taking casts, you must visit a doctor to adjust the cast frame and the finished product. Subsequently, visits will also be required to correct the prosthesis already in use by the patient.
- The possibility of an allergic reaction to the residual monomer of plastic fragments of the prosthesis.
- The upper clasp prosthesis may at first cause taste disturbances and cause nausea due to its fit to the palate.
- The relatively high cost of prosthetics.
Denture care rules, adaptation requirements
There are few rules for leaving. In order to successfully use the clasp denture, it must be rinsed after each meal and thoroughly cleaned at least 1-2 times a day. When cleaning, the use of coarse abrasive products (pumice, tooth powder, etc.) that can lead to damage to the product should be excluded. Also, aggressive chemicals (acids, alkalis, etc.) and hot liquids should not be used. It is optimal to use a freshly prepared specialized solution, which includes surface-active detergents, antiseptics and proteolytic enzymes.
The addiction to clasp prostheses for each occurs with individual characteristics. However, in most cases, the first stage of irritation occurs. Clasp prostheses on the upper jaw are perceived as a completely foreign body, inappropriate in the oral cavity. This may be accompanied by increased salivation, soreness, impaired diction and chewing of food, and often nausea and headaches. However, very quickly these sensations become dull, and eventually disappear completely. The patient forgets about the existence of artificial teeth in the mouth , using them with the same ease as natural ones.
To achieve such a desired result, it is extremely important to comply with all the recommendations of the attending physician:
- At first, the denture is always worn in the mouth, removing it only at night or for hygienic treatment.
- To improve diction and accelerate addiction, it is important to read aloud or talk a lot.
- Timely come to the dentist for follow-up examinations and correction of the finished prosthesis.
The cost of installing dentures
If dentures became necessary, the prices of various types of prosthetics can become an important criterion in the choice of design. The cost of a simple clasp prosthesis is at least 10 thousand rubles. The clasp of complex design can cost from 15-17 to 25 thousand. In the case of fixation by attachments (locking elements), the upper clasp prosthesis can cost up to 40-50 thousand, since this will also require the manufacture of several cermet crowns and the purchase of attachments proper.
