A person may lose teeth during life, becasue of different reasons. One of the most apropreate method for the treatment to make a prosthesis is to prepare the teeth adjacent to the space in size.
Previously, fix partial dentures were made of gold (gold is the most suitable material for the human body), then it was replaced by the use of porcelain due to both economic reasons and the increase in aesthetic expectations.
Porcelains are materials that need to be strengthened against breakage. For this purpose, metal infrastructures are used to support the porcelain, but for aesthetic gains, the gray color of these metals used in the infrastructure should be covered.
Zirconia, another infrastructure material, is advantageous due to its white color. Another advantage is that it has a structure that allows light transmission compared to metals at the point of light transmission.
Zirconia has become popular thanks to its superior optical and mechanical properties, but it still cannot fully provide an opaque appearance in the construction of anterior teeth. In order to eliminate this deficiency, the use of glass ceramics, which allows the transmission of light as much as natural teeth, would be a more correct decision. In short, fixed partial dentures are made by preparing the teeth in that area to replace the lost teeth, and the material to be preferred is determined completely according to the need.
