What is silicone impression material?

An impression is a negative impression of an object, and an oral impression is a negative impression of oral tissue. The material used in making an impression is called impression material. The making of dental impressions is a process in oral restoration, and its quality is directly related to the final restoration effect. Silastic impression materials belong to the high polymer synthetic rubber, which has the characteristics of good elasticity, toughness, and strength. In addition, silicone rubber impression also has the advantages of good fluidity, plasticity, volume shrinkage, and the formation of an impression of high elasticity, toughness, and strength, but also can be repeatedly turned over the model. The impression made with high accuracy, good chemical stability, does not change with the model material, easy to release is the ideal type of impression material. According to the different polymerization temperatures, silicone dental putty is divided into room temperature sulfuration type and polymerization type.

What are the ingredients of silicone impression materials?

Silastic impression materials are only used for Impression Materials with very high precision and a relatively small range. There are three kinds of silicone rubber impression materials, namely silicone rubber, polyether rubber, and polysulfide rubber. The silicon rubber offset impression material has the best performance. Silicone rubber impression material is an elastic and irreversible impression material, which is divided into two kinds: condensation type and addition type. The matrix of condensed silicone rubber is dihydroxyl polydimethylsiloxane, the crosslinking agent is ethyl silicate, triethoxy silane, the catalyst is tin octanoate, dibutyltin laurate, and the filler is gaseous silicon dioxide. Generally, it is a two-component dosage form, with one component as the matrix and one component as the cross-linker and catalyst. There are also three components that simply separate the substrate, the cross-linker, and the catalyst. The main component of silicone rubber processing molding is methyl vinyl siloxane, which not only has the essential characteristics of the table, and its performance is better, but the price is high.

Dental impression putty is more and more widely used in clinical treatment. It makes the impression made by post core, porcelain crown, Zhouding bridge, and denture in fixed restoration more accurate and stable in shape, which is conducive to the later production of technicians, so that the fabricated post crown, porcelain, and other restorations can be more closely integrated with the body tissue, and the patients are more comfortable.
