Dental materials

Dental composite

A composite is a material composed of mineral fillers and an acrylic resin, which cures under the influence of heat, pressure or light. The composite is tooth-colored and can also be used in a dental laboratory. It is softer in comparison to porcelain and its advantage is that it can be supplemented even when it is already in the mouth.

It is used for aesthetic dental fillings, for making partial crowns and shorter bridges. The disadvantage of the composite is that it requires more maintenance, its durability is shorter compared to porcelain.

 

Full (Feldspar) porcelain

The most natural look for dental substitutes is achieved with full porcelain. Usually, due to the lower strength of full porcelain, we choose it for dental crowns or veneers on the front teeth, where the forces are smaller and when enough enamel is available to provide a firm bond. In this case, the porcelain veneers become extremely durable.

 

Glass ceramics

Glass ceramic dental crowns are highly aesthetic and they allow good tooth translucency and a variety of color effects. Compared to full (Feldspar) porcelain, they have a higher strength, which allows them to be used for single crowns or shorter bridges, especially in the front teeth.

 

Metal-porcelain technique

Porcelain metal technology has been used for over 100 years and is the "gold standard" for every new material on the market. When making bridges, this material is the first choice because it is proven, reliable and long-lasting.

Crowns in metal-porcelain technique combine the advantages of metallic materials (strength, toughness) and dental porcelain (appearance).

 

Solid ceramics - zirconium

Zirconium oxide ceramics have very good mechanical properties and are extremely solid. Due to its strength, it is very close to metal-porcelain technique, so it can be used to make frames, bridges and crowns. Due to its intense light and non-transparent color, it is advantageous to use it when the tooth is colored or very dark, since zirconia ceramics can completely mask the uncomfortable basic color of the tooth of the wearer.
