Dental impression materials are used to make impressions of teeth and hard and soft tissues of the mouth. There are elastic and non-elastic, reversible and irreversible impression materials. So, what items are used in the process of making dental impressions?

 

Here is the content list:

  • Dental impression trays

  • Dental impression materials

 

Dental impression trays

The choice of dental impression trays is of great importance in obtaining a fine dental impression. The trays used for taking impressions should be rigid, otherwise, they tend to distort when highly adhesive impression materials are used.

After selecting a suitable tray, apply a special adhesive and, once it has cured, inject the silicone evenly in one direction along the tray to avoid air bubbles.

 

Dental impression materials

Dental impression materials can be classified in various ways.

Depending on the shape or elasticity of the impression, there are two types of materials: elastic and non-elastic. Elastic impression materials are those that are shaped so that the impression is elastic; non-elastic impression materials are those that are shaped so that the impression is not elastic.

According to whether the impression material can be used repeatedly, the impression material is divided into the reversible impression material and irreversible impression material. Those that can be used repeatedly are called reversible impression materials. Conversely, materials that do not return to their original state after shaping are called irreversible impression materials.

Depending on the form of solidification of the dental impression material, the material can be divided into chemical solidification, thermal solidification, and room temperature fixation. Chemical solidification is the solidification of the material after a chemical reaction in use. The thermosetting class is a thermoplastic material, which has the characteristic of solidifying on its own after heating and softening, and cooling. The room temperature stereotype class is the use of the plasticity of the material, at room temperature with a slight pressure qualitative.

 

Dental Impression Material

 

Common dental impression materials are as follows.

Alginate-based impression materials. A powdered material that is mixed and then solidified. The advantage is that it is cheap and easy to handle. The disadvantage is that it shrinks more and does not reflect the state of the tooth more accurately. It cannot be used to make impressions of fixed dentures, such as inlays, porcelain crowns, cast crowns, precision attachments, etc.

Agar-based impression materials. It is cheaper and can be used for fixed restorations, but has the disadvantage of being easily broken and brittle.

Silicone rubber-based impressions. Highly accurate and can be used for a variety of restorations. It has become increasingly popular in China in recent years and can be divided into three categories.

With economic development and social progress, more and more people are paying attention to the aesthetics of their teeth, and more and more people are opting for orthodontic and cosmetic dentistry. Choosing a good set of dental impression kits is the first step in truly reflecting the condition of our teeth and improving their condition.
