Bar prosthesis - is a modern and comfortable removable dental structure. These prostheses usually resort in cases where a person missing six or more teeth. Medical device restores the integrity of the dentition and prevent further destruction of the chewing system.

What is in the clasp prosthesis

This removable prosthesis consists of a metal frame, which includes the fixing elements and the arc (clasp) and parts with artificial gums and teeth. The frame is made of titanium, or hromokobaltovyh zolotoplatinovyh alloys.

Using the arc reduces the dimensions of the construction, which makes a more compact prosthesis. Arc closes sublingual space and sky only partially, so it is not broken, there remains sensitive, do not arise inconveniences in ingestion. In the application of the metal frame is possible to reduce the thickness and volume of the plastic base (base) with artificial teeth.

Advantages and disadvantages

Compared to conventional prostheses made of plastic clasp structures have several advantages. The main ones are:

• Easy wear;
• Long service life (about five years). For example, the prosthesis plastic is recommended to change every two years. This is due to the fact that bone and gums by such structures atrophy faster than under the clasp. Due to changes in the tissue bed of the prosthesis no longer match its shape. There is pain and deteriorating fixing dental apparatus;
• Strength and reliability. Metal frame - the basis of the prosthesis, so the risk of failure is very low;
• The load on the gums when wearing clasp dentures will be less, and it is distributed between healthy teeth;
• The prosthesis is not necessary to remove the night;
• Not there prosthetic stomatitis Stomatitis - to breath fresh .

We clasp dentures there are also disadvantages. It:

• The need for periodic removal and installation, and other hygienic measures;
• The high price of more aesthetic options prostheses, which are almost invisible in the mouth.

Kinds

Clasp dentures differ in their mode of fixation. There dentures:

• With clasps;
• On locks (attachments);
• On the telescopic crowns.

Clasps - processes of metal, which depart from the framework of the prosthesis and cover the abutments. As a result of this design is firmly fixed. With clasps pressure when chewing is distributed between the mucosa and the prosthetic bed tissues surrounding the teeth. The price of dentures with clasp fastening lower than other types of similar devices.

But in some situations, metal clasps can be installed in the oral cavity in humans only with access to the front surface of the teeth. Therefore, they are not as aesthetically pleasing as the clasp prostheses with other methods of attachment.

Attachments - special Microcastle, half of each of them is on the prosthesis, and the second part is on the abutment teeth. When the prosthesis is worn, the Microcastle snaps.

Lifetime prosthesis on attachments is five to seven years. Construction via Microcastle firmly attached, and does not weaken the fixation over time. But if such attachment fails, then it will be difficult to replace.

High Cost - One of the major drawbacks of these prostheses. The design is necessary to involve more teeth than in other types of fixation. The supporting teeth for crowns take, as soon as they can be mounted side Microcastle. Making clasp dentures to attachments requires highly skilled dental technician and podiatrist.

Telescopic crowns - another way to fix dentures. They represent a system that consists of two parts. Such attachment is used at low crowns abutment teeth when using conventional clasps will not work securely attach the prosthesis. The first such crown is cemented on the tooth, and the second is in the partial denture. Thereafter, one bit lasts for another, and the construction is firmly retained.

The latter method is considered to be a universal prosthetics. Over time, the number of abutment teeth may change, and the prosthesis will require only a small correction.

Prosthesis Kvadrotti

This clasp prosthesis, frame and clasps which are made of high quality plastic. It does not cause allergic reactions Allergic reactions: how to understand why you tickle in the throat   and it has no toxic effect on the mucous membranes of the oral cavity.

Prostheses have a small thickness and high strength. They are translucent, which gives them a natural and aesthetic appearance. Catches they are made of the same material as the gingival base, and have the same color. The design does not rub gums and not colored under the influence of food. The patient gets used to the prosthesis so quickly.

Prostheses Kvadrotti are very flexible and do not break. Therefore, they can be installed athletes and people who have traumatic profession.

How to care for dentures

Care partial denture takes very little time. Every morning and evening you need to clean the prosthesis from the plaque and food particles.

At night, the denture can be worn. Especially do not recommend it to people who have diseases of the mouth and prosthesis is their curative measure. When installing design is best to consult with a specialist about the care. This is due to the fact that the prostheses can be manufactured from different materials, each of which has its own characteristics.

Clasp dentures perform several tasks. They replace missing teeth with artificial and restore chewing function. Also use them to offset, or splinting mobile teeth (for example, periodontitis Periodontal disease: deep problem   or periodontitis). Clasp dentures contribute to the aesthetic rehabilitation of patients, because even when viewed up close the teeth will be difficult to guess what part of the tooth is removed.

Stomatitis - a non-specific term used to describe conditions that are characterized by inflammation and pain in the mouth that can disrupt a person's ability is, to say, as well as a negative impact on sleep Dreams: how to understand our dreams . Canker sores may occur in any area of ​​the oral cavity, including on the inner sides of the cheeks, on the gums, tongue, lips and palate.

Types of Stomatitis

Some of the most common types of stomatitis:

• Aphthous ulcers. Pale or yellow ulcer with a red bordering; one or more of such ulcers usually formed on the cheeks, tongue or lips on the inner side.
