Expert opinion:
Q1: why should silane coupling agent be used for resin based ceramics?
Professor Yue Lin: silane coupling agent is a low molecular organic silicide. Its function is to improve the surface activity of substances such as silicate, and then some surface active groups can be connected with the groups of adhesive to increase the bonding performance and bonding strength.
Q2: resin based ceramics are not ceramics, but why are they classified as ceramics?
Professor Tan Jianguo: it is true that resin based ceramics are not ceramics, but we call them ceramics because of their commonness - resin matrix. Although it is a complex of resin matrix and inorganic materials, there are many classifications of these materials. The improvements of different manufacturers are different, which are mainly divided into two categories: one is the frame structure and grid structure that turns inorganic materials into porcelain, Then infiltrate the organic matter into it; More improvement of a kind of composite resin on filler. Why porcelain? Although it is not ceramic in strict definition, it is very close to porcelain because of its similar properties with ceramic materials, including aesthetics, strength, adhesion, wear resistance and so on. At present, according to the definition of the international naming Committee, the materials with inorganic refractory as the main body through cutting, sintering and die casting can be called "porcelain". Therefore, although it is not ceramic in the strict sense, it tends to be named resin based ceramics, also known as ceramic like materials. In clinical application, resin based ceramics occupy the same technical space as "ceramics". Resin based ceramics have the characteristics of both ceramics and resin. Its elastic modulus is low and similar to dentin. The biggest advantage is to make in crown restoration, inlay, high inlay and inlay crown, which has very good lateral wall force and good stability.
Q3: what are the differences and advantages between resin based ceramics and other materials in terms of bonding?
Professor Huang Cui: resin based ceramics have the properties of both resin and porcelain in terms of bonding. Different manufacturers have different treatment methods according to different silica content. Aerchuang Runci recommends the use of sand blasting and silane coupling agent. Sand blasting is a very good form of physical coarsening tissue surface reported at home and abroad. For resin based ceramic sand blasting, attention should be paid to controlling time and pressure to reduce damage to resin based ceramic interface. The coarsened surface caused by sand blasting can really become coarsened surface through ultrasonic cleaning, Then silane coupling agent is used. Finally, it is suggested to use double curing resin cement to bond resin based ceramics.
