Classification of dental wax blocks?

Dental wax blocks in oral medicine can be divided into many types according to their use and properties. The following is a summary of the main categories of dental wax blocks:

First, classification by use

1. Impression wax:

- Use: Mainly used to make oral impressions to help doctors understand the shape and structure of the patient's mouth.

- Features: It has good fluidity and plasticity, and can accurately replicate the shape and details in the mouth.

2. Model wax:

- Subdivision type: including casting base wax, inlay wax, etc.

- Use: Used to make models of restorations, such as wax shapes of crowns and Bridges.

- Features: With high hardness and stability, can withstand high temperature and pressure in the casting process.

3. Modeling wax (process wax) :

- Subdivision type: jaw wax, mixed wax (utility wax), box wax, etc.

- Use: Used to make a variety of complex oral structures and forms, such as jaw dykes, artificial teeth, etc.

- Features: With good plasticity and engraving, can meet the needs of fine production.

Second, classification by composition

Dental wax blocks are made of a variety of ingredients, but are mainly composed of a mixture of the following substances:

1. Paraffin:

- Source: A mineral wax.

- Features: Low melting point, easy to process and shape.

2. Beeswax:

- Source: A kind of animal wax.

- Features: soft, easy to bend, toughness, plasticity, good carving, luster.

3. Floor wax:

- Source: A mineral wax.

- Characteristics: Similar to paraffin, but may have a higher melting point and hardness.

4. Synthetic wax:

- Features: Obtained by chemical synthesis method, with specific physical and chemical properties to meet different use needs.

In addition, some dental wax blocks will add EVA plastic and other components to improve their elasticity, bending strength, process engraving and other properties.

Third, other categories

In addition to the above classification by use and composition, dental wax blocks can also be classified according to other criteria, such as shape (block, strip, mesh, wrinkled, etc.), color (such as deep red for winter wax, pink for summer wax) and whether they contain special additives.

To sum up, the classification of dental wax blocks is diverse, and doctors need to make comprehensive consideration according to the specific needs and oral conditions of patients when choosing to use them. At the same time, with the continuous progress and innovation of dental technology, the types and performance of dental wax blocks will continue to be enriched and improved.
