There is a method of making temporary crowns using acrylamide plastic. The method consists in the following: removal of casts to preparation of the tooth, the mixing of the paste and the catalyst (in the proportions specified in the instruction), the tooth preparation required under the construction (porcelain, ceramic-metal), the imposition of ready-made plastic in the area preparerow tooth in the previously received print setting print on dentition (plastic takes place so removed tissue), removal of the impression from the oral cavity, removing the finished crowns, removal of excess plastic, smoothing the edges of the crowns, temporary fixation (H. A. Kalamkarov Orthopedic treatment with the use of metal-ceramic prostheses. Moscow: Copper Sphere, 1996, S. 53-54).
The disadvantages of this method are as follows: mechanical factor, which results in the injury of the mucous membrane, and subsequently inflammation of the gums, as well as toxic effects of residual monomer, which can lead to adverse changes in the body, Economically spent a lot of money (impression spoon, attigny material, plastic), and the time of admission is extended.
Closest to the claimed method is Yu situational model is extruded film of 0.6-0.8 mm by means of deep drawing apparatus “S”. The film is cut crown scissors and sealed with silicone spray. Then knead acroloxidae plastic, which fill the resulting cap, and injected into the patient's mouth. After hardening of the plastic cap clipped. In the future produce grinding and polishing (VP of Tregubov. M. H., Steinhart, L. M. Mishnev Prosthetic dentistry. Applied materials. St. Petersburg: Spec. Lit., 2001, S. 274-276).
In this method there are a number of disadvantages: it is not always possible to achieve esthetic and functional qualities of the finished design, the technology is time-consuming and expensive due to the use of the “S”. The use of acrylic plastic also entails negative effects of residual monomer, which, in turn, can have a toxic effect on the mucous membrane of the mouth.
The technical result of the invention is to simplify and cheapen the method of making temporary crowns, improving the aesthetic and functional qualities of temporary structures.
The technical result is achieved by the fact that the selection of the tooth is from a set of artificial teeth according to the size and shape of the individual and slowly heated over the flame of the burner (Fig. 2). After the membrane was plastic, artificial tooth is injected through the membrane in silicon mass from a set of “Adapta”. After 2-3 minutes, the artificial tooth is extracted from the membrane, the result is a cap that is made of filling material chemical hardening, such as Kristalyn”. After curing, the cap is removed from prepareimage tooth.
The method is as follows. The tooth preparation is produced but the General accepted method. Selection of the tooth is from a set of artificial teeth, considering the size, the shape of individual features. The membrane is installed in the holder and slowly heated over the flame of the burner. After the membrane was plastic, artificial tooth is injected through the membrane in silicon mass (Fig. 3). After 2-3 minutes, the artificial tooth is extracted from the membrane, thus, turns out to cap future temporary crowns (Fig. 4). Scissors clipped the cervical edge of the cap, visual quality is assessed. After being in fitting the cap on the tooth. Further kneaded filling material chemical hardening, such as Kristalyn”, taking into account the instructions provided to him. The material is introduced into the cap, eliminating OBSE, in its absence you can use vaseline to prevent the adhesion of the filling material to the tooth. After chemical hardening material cap snipped and removed with a spatula. The finished crown is polished and a pin is stuck on the tooth stump with material for temporary fixation, for example “Repin”.
