What are dental technical materials?

Dental materials are the starting materials for the preparation of special compositions, prostheses, crowns and other products needed in practical dentistry and orthodontics. There are a lot of them. However, specialists have led them to a general classification. Therefore, today there are basic and auxiliary dental equipment.

Main characteristics

There are a number of requirements that all dental materials must meet:

• Hygienic. All of them must comply with certain norms and not worsen hygiene of the oral cavity.
• Toxicological. They should not irritate and cause an allergic reaction.
• Aesthetic. They should repeat the tissues of the oral cavity.
• Chemical. Their chemical composition should be constant. They can not be corroded.
• Physical. They are always strong, do not change their size, and they are also wear-resistant.
• Technological. They are easy to process, prepare and shape.

Basic

Basic dental technical materials are used to create prostheses, seals, apparatus. Among them are:

• Metals (including noble ones: gold, silver), as well as their glory. Today, in the dental practice, about 500 different metal alloys are used. Palladium, gold, platinum is the standard. Products from them are non-toxic, durable and not subject to corrosion. Studying titanium alloys, scientists come to the conclusion that this is an excellent and cheaper alternative to gold.
• Ceramics. This includes porcelain and glass (vitreous matter). From the first produce crowns, bridges, tabs. The latter are used for prosthetics of the anterior dentition .
• Polymers - inexpensive, but a durable option for creating removable and permanent prostheses. Use this material and for restoration of teeth.
• Composite materials. It is from them that fillings are made. They are also used for cladding all metal parts of metal-plastic prostheses. There are in the form of liquid, paste.

Auxiliary

At various stages of creating prostheses, special auxiliary dental materials are used:

1. Impressive means are necessary for creating casts, maps of hard and soft tissues. As a result, the specialist receives a working, diagnostic or auxiliary model of the future prosthesis.
2. Modeling materials are needed for the manufacture of a denture stamp, crown or apparatus.
3. Molding materials are dental tools that help to obtain a final shape for subsequent casting. They must necessarily have certain characteristics. First, such materials provide clear contours of the future product. Secondly, they should be easily separated from the resulting model. Finally, they all harden very quickly (within 10 min.)

In the photo, dental technology does not show all its features. Therefore, dentists and specialists in prosthetics choose consumables exclusively based on their experience. The companies that produce them quite a lot. However, not all produce high-quality and reliable goods.
