The method of prosthetics in the absence of a coronal part of a tooth

 

(57) Abstract:

The invention relates to medicine, namely to prosthetic dentistry and can be used in the prosthesis with complete or partial destruction of the tooth crown. The method consists in the fact that the tooth are made of metal cast copings, her Tegaserod and occiderunt. Then, on the entire surface of the tab, apply a thin layer of the ceramic mass - Apacer and produce firing. Pin tab is fixed on the tooth and it made an artificial crown of gold alloy ceramic alloy of gold, pure ceramic (IPS Empress). The technical result is to prevent the inclusion of metal ions in the oral cavity to avoid toxic and allergic reactions to the metal and electrogalvanic syndrome.

The invention relates to medicine, namely to prosthetic dentistry and can be used when oral prosthetics patients with complete and partial destruction of the tooth crown.

The known method prosthetics oral cavity of patients in the absence of a coronal part of a tooth, including the manufacture of pin stump metal tab, it locks in place on the tooth and manufactured by Opticheskie dentistry. - SPb., 1997. - S. 127-129 - prototype).

For the manufacture of cast metal pin copings use cobalt alloys (KHS), Nickel-chromium alloys and other Under the action of saliva (corrosive environment) in the oral cavity of the patient and reach the metal ions from the metal tab. Ions of metals, especially Ni, cause toxic and allergic reactions of the body, galvanize and other adverse events (Gaza L. D., Allergic diseases in prosthetic dentistry. - M., 1988. - S. 76-88. Kopeikin Century. N. Prosthetic dentistry. - M., 1988. - S. 411-441).

The main disadvantages of this method, taken as a prototype of the proposed invention are:

- do not exclude the possibility of penetration of metal ions in the oral cavity and the body of cast metal copings due to the lack of reliable isolation from saliva, which leads to toxic and allergic reactions and galvanism;

under the action of saliva causes corrosion of the metal tab that leads to racemetirosine inlays and crowns.

The aim of the invention is to prevent the inclusion of metal ions in the oral cavity to avoid toxic-allergic reactions to metals, corroborative is as follows.

The tooth is made of metal cast tab, it Tegaserod and occiderunt. Then, on the entire surface of the tab, apply a thin layer of the ceramic mass - opaker (opaque layer) and produce firing. Pin tab is fixed on the tooth and it made an artificial crown of gold alloy ceramic alloy of gold, pure ceramic (IPS Empress).

The method of prosthetics in the absence of coronal tooth structure is as follows.

Conduct a comprehensive examination of the root (root) of the tooth. Dissect the hard tissues of the tooth root, expand its channel (channels). Produced cast metal tab and the pin is stuck in the tooth. Next Tegaserod and occiderit metal tab, for example from CJC. Then, on its entire surface a thin layer of ceramic material of opaker (IPS Classic, Duceram and others) and produce firing the opaque layer in a vacuum furnace. A pin is stuck tab fixed on cement (Unifac and others). Remove double cast of the jaw and make the tab a crown of gold, ceramics and other materials standard methods.

Clinical example. Patient K., 46 years old, came in dental Rehabilitation center, Samara complaints E, are at the level of the gingival margin. On the radiograph 4; buccal and palatal canals well passable. The canals of root-filled. The remaining teeth are intact.

Diagnosis: complete absence of the crown portion 4;.

Treatment: prepare the stump 4; tooth under the metal tab, channels roots qualifies under the pins. Produced cast a tab from CJC and the pin is stuck in the tooth. Next Tegaserod and occiderit metal tab. Then, on its entire surface a thin layer of ceramic material of opaker (IPS Classic) and produce firing the opaque layer in a vacuum furnace. A pin is stuck with the tab on the tooth stump, fixed on cement (Wistat). Remove double cast of the jaw and make the tab a crown made of ceramics on the gold alloy. Crown pin is stuck and fixed on the copings cement.

The proposed method in the absence of prosthetic crown part of the tooth allows preventing metal ions from the tabs at the mouth, which prevents the occurrence of toxic and allergic reactions, galvanized. In addition, it eliminates the corrosion of metal and rastamaniak inlays and crowns. The method has been tested on 26 patients. All results are positive.
