Dental he alth is not only of aesthetic importance, it is also very important for the absence of pathological processes in the internal organs of a person. If the function of chewing is disturbed, the organs of the gastrointestinal tract suffer. With developing caries, a person can not only introduce an infection into the body, but also lose some teeth, which entails new problems, such as the selection of prostheses.
What are jaw dentures for?
Defects in the dentition are very diverse, and their elimination requires an exclusively individual approach to each person. Prostheses 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 dentures be the best solution?
Benefits of clasp dentures
The clasp prosthesis is rightfully considered one of the best ways of prosthetics in case of partial loss.
- In most cases, the clasp prosthesis does not require preparation of the patient's existing teeth.
- The clasp prostheses on the upper jaw haverelatively small (compared to plate, acrylic or nylon mucosal overlap area.
- Individual and high-precision casting of the frame of the clasp prosthesis allows you to make prosthetics as reliable and convenient as possible. The materials used (chrome-cob alt alloy, gold, etc.) meet all modern strength and hygiene requirements.
- A wide variety of supporting, retaining, supporting-retaining and other clasps allows you to plan the design of the prosthesis in such a way as to minimize pressure on the mucous membrane and slow down the atrophy of oral tissues, while achieving the best fixation of the product.
- Planning the construction of a 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 for each individual patient with the choice of the optimal route of insertion and application of the product.
- In the presence of increased mobility of the remaining teeth, clasp prostheses for the upper jaw can partially perform splinting functions, prolonging their service life.
- Getting used to clasp prostheses comes faster and easier in comparison with the lamellar counterpart.
Fixation of clasp prostheses
The main means of fixing a clasp prosthesis is clasps (special processes of a 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 prevent it frommove in horizontal and vertical directions while talking and eating. Also, supporting clasps are 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 chewing efficiency.
Clasp prostheses for the upper jaw are additionally attached with a flat metal arc adjacent to the mucous membrane of the palate. This function is especially evident with the bilateral loss of several extreme chewing teeth.
In case of insufficient fixation 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 denture.
Indications for the establishment of clasp prostheses
- Included dental defects limited to natural teeth on both sides (both single and multiple).
- Single-sided and double-sided end defects.
- Any defects in the dentition, aggravated by periodontal disease of the remaining teeth.
- Defects in the dentition, combined with significant atrophy of the alveolar processes of the jaws in the edentulous areas.
Lock clasp prostheses
A special kind of removable products suchtype is a lock 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 the two parts of the lock are combined, the prosthesis receives a secure 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, which is removed by the patient using a special device. This is necessary for the daily extraction of the prosthesis for hygienic care. Despite the relative complexity of this type of locks, they provide the most reliable and comfortable fixation.
Disadvantages of this method of prosthetics
- The complexity and accuracy of the prosthesis. High-precision casting and the presence of diverse structural elements require high qualifications from all employees of the dental clinic: doctor, technician and caster.
- Duration of production and the need for several patient visits. In addition to taking impressions, a visit to the doctor is required to fit the cast frame and the finished product. In the future, visits will also be required to correct the prosthesis already used by the patient.
- Possibility of an allergic reaction to the residual monomer of plastic fragments of the prosthesis.
- The upper clasp prosthesis may initially cause taste disturbances and cause nausea due to itfit to the palate.
- Relatively high cost of prosthetics.
Prosthetic care rules, adaptation requirements
There are few rules for leaving. In order to successfully use the clasp prosthesis, it must be rinsed after each meal and thoroughly cleaned at least 1-2 times a day. When cleaning, the use of coarse abrasive agents (pumice stone, tooth powder, etc.) that can lead to damage to the product should be excluded. Also, do not use aggressive chemicals (acids, alkalis, etc.) and hot liquids. It is optimal to use a freshly prepared specialized solution, which includes surface-active detergents, antiseptics and proteolytic enzymes.
Getting used to clasp prostheses for everyone occurs with individual characteristics. However, in most cases, the irritation stage occurs first. Clasp prostheses for the upper jaw are perceived as a completely foreign body, out of place 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 follow all the recommendations of the attending physician:
- First time to constantly wear a prosthesis 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.
- Show up to the dentist in time for follow-up examinations and correction of the finished prosthesis.
The cost of installing dentures
If dentures are needed, the prices of different types of prosthetics can become an important criterion in choosing a design. The cost of a simple clasp prosthesis is at least 10 thousand rubles. A clasp of complex design can cost from 15-17 to 25 thousand. In the case of fixation with attachments (lock elements), the upper clasp prosthesis can cost up to 40-50 thousand, since this will also require the manufacture of several metal-ceramic crowns and the acquisition of the actual attachments.
