What kinds of impression materials can be divided into?

What kinds of impression materials can be divided into? I believe this is the topic that everyone wants to know most. The following medical education network Xiaobian to collect and collate the relevant information, we hope to understand the classification of oral impression materials can help.
The classification of oral impression materials: 1.. According to the elasticity of impression molding, it can be divided into two kinds: elastic impression material and non elastic impression material. The elastic impression material is molded and the impression is elastic; the inelastic impression material is a material that is inelastic after molding.
2. according to whether the impression material can be used repeatedly, the impression material is divided into reversible impression material and irreversible impression material. It can be used repeatedly and is called reversible impression material. Conversely, the material that does not revert to the original state after molding is called irreversible impression material.
3., according to the form of the solidification of the impression material, it is divided into chemical coagulation class, heat coagulation class and normal temperature setting class. Chemical coagulation is the solidification of materials by chemical reactions in use. Thermosetting is a thermoplastic material, which has the characteristics of self solidification after heating, softening and cooling. Normal temperature setting is the use of material plasticity, at room temperature, a little pressure qualitative
