Clasp dentures on attachments are one of the types of partial dentures. Their feature is the locking method of attachment. Such structures are fixed on the abutment teeth. They have an excellent appearance, and also fully restore the functionality of the jaw. Naturally, they should not be overloaded.
Features of the structure of the product
The clasp prosthesis on attachments is made of a soft metal frame in the form of an arc with locks. A plastic base is fixed on it, on which artificial dental crowns are located.
The locking mechanism also has a complicated structure. It consists of two parts: patrician and matrix. The first is mounted directly into the crown or other structure, which cannot be removed. The matrix part is connected to the frame.
Product Advantages
Clasp dentures on attachments have the following advantages:
- They help to ensure the correct distribution of the load on healthy crowns and maintain their integrity.
- Prevent loosening of the dentition.
- Smiles do not change the aesthetics, since these designs are attached imperceptibly.
- They help prevent damage to the gum tissue, as well as enamel during installation and removal of the structure.
- High dimensional accuracy.
- Getting used to the prosthesis does not take much time.
- High quality materials ensure product durability.
- Clasp dentures on attachments are made so that their matrices can be changed and reused.
- The product is stably fixed on the jaw.
- Allow to maintain normal diction.
The only drawback of the design is its cost. A clasp prosthesis on attachments, the price of which is 30,000 rubles, is far from affordable for everyone.
Indications and contraindications for use
The presented product can be used if:
- All abutment teeth cannot be made parallel, that is, a single route to the introduction of the prosthesis is impossible.
- The design is mounted on implants.
- The functional suitability of the support crowns is called into question.
- It is necessary to ensure reliable fixation of the artificial product and the abutment tooth, if the latter has a small crown height.
- The patient is diagnosed with terminal or included defects of the dentition.
- There is a violation of speech, as well as the aesthetics of a smile.
- The alveolar bone atrophied.
- Teeth wear out very quickly.
However, the clasp prosthesis on attachments, the price of which is quite high, has some contraindications for use:
- Insufficient width of incisors and fangs.
- The height of the crown, which does not reach 5 mm.
- Poor oral hygiene.
- The inability to periodically visit a doctor.
- Cerebrovascular disorders, Parkinson's disease, arthritis.
- Atrophy of periodontal support crowns.
Varieties of locks
In addition to the castle, there is also a clasp prosthesis clam. Its main difference is that it is attached to molars with the help of special hooks.
As for the castle structures, they can be classified as follows:
- In the place of fixation: intra-root, intracoronary, inter-coronal and auxiliary.
- By the type of stiffness of the product: semi-labile, labile, rigid.
- By design: spherical, rack, beam, swivel.
If we compare the clasp prosthesis clamper and castle, then the fastening of the first is visible to prying eyes, which affects the aesthetics of the dentition.
Product Installation Features
Fixation of the structure is carried out in several stages:
- First, the jaw must be prepared for installation. To do this, the enamel is cleaned with ultrasound, and pathologies of the oral cavity and teeth are treated. In addition, you will have to perform a small grinding of the crowns.
- Additional processing of supporting teeth for the installation of the prosthesis and locks. They need to install special crowns made of cermet, as subsequently they will account for most of the chewing load.
- Actually installation of the product. Thanks to the most accurate manufacturing of the structure according to pre-made casts, it fits well to the jaw.
Whatever methods of fixation were proposed, clasp dentures of the castle type are one of the best and highest quality.
Features of care and use of the design
In principle, oral hygiene does not change. Teeth should be brushed twice a day, floss and cleaning rinses should be used. However, the use of the presented products has some features:
- Dentures on attachments, like any other constructions of this type, must be protected from increased load.
- The degree of density of fixation of the prosthesis should be selected individually in each case, which affects its final cost.
- After some time, the locks will need to be changed. The interval, as a rule, is 1-1.5 years. The procedure itself lasts only 15 minutes.
- After installation, after some time, it will be necessary to rebase the prostheses, add hard tissues, on which the basis of the product will rest.
- In the period of addiction, it is not recommended to remove the prosthesis at night.
Despite all the advantages of this product, you should definitely read the opinions of other users about it. If the dentist proposes to install arch prostheses on attachments, reviews will help you make the right choice.
Mostly people respond to such designs positively. For example, users like the high aesthetics of the product, since the mounts are not visible to the prying eye. In addition, they are easy to use, easy to remove, perform their functions well.
And those people who have been using such designs for a long time say that they do not have to get used to for a long time. Although they are not very happy with the high cost of the product.
That's all the features of dentures on attachments. In any case, before using them, you need to consult an experienced specialist or even several doctors. Be healthy!
