Dentures should look aesthetically, work well, last a long time and do not burden the organism. The denture material is also important. Very good material quality and precise workmanship ensure high wearing comfort, natural aesthetics, stability, biocompatibility and long service life of the dentures.
Denture Materials And Their Applications
There are many materials that are used in dentures. Many properties of the denture depend on the denture material used: the sensitivity to heat and cold, the biocompatibility (body compatibility) and the wear and thus the life. Below we take a look at the most common materials for dentures:
Dentures Made Of Metal
Since very few metals are suitable in pure form as a denture material, they are allowed. It is differentiated in precious metal alloys and non-precious metal alloys. The main constituent of the respective metal is palladium and gold alloys as well as non-precious metal alloys.
Non-precious metal (NEM) is a proven and inexpensive and biocompatible denture material, which has become established in the standard care. Cash benefits include NEM crowns, NEM bridges, full dentures, and partial dentures.
Gold (dental gold) is durable, biocompatible and suitable for allergy sufferers. However, the rising gold price is making the classic gold crown more expensive. Nowadays materials are more trendy, which can hardly be distinguished visually from the real teeth.
In addition to compatibility, resilience and cost of dental prosthesis and the so-called edge fitting of the metal is important. It indicates how precisely, for example, the crown edge can be adapted to the prepared tooth. Many metal parts of the dentures can be veneered in the field of view with plastic or ceramic, to look like real teeth.
Dentures Made Of Ceramic
Ceramic as a denture material is hardly distinguishable from natural teeth due to its appearance. Therefore, this material is often used for dentures in the anterior region.
Glass-ceramics for dental technology is manufactured on the basis of aluminum, magnesium or silicon oxide. They are highly temperature resistant and are partially processed at temperatures around 1,500 ° C.
Newly developed ceramic materials such as zirconium dioxide (abbreviated to zirconium oxide) are not only suitable for ceramic veneers, but also for the production of crowns and bridges. The material thus proves to be a true all-rounder in dental technology and is therefore used more and more frequently.
Dental prosthesis with zirconium oxide base is also suitable for allergy sufferers, while extremely durable and durable. It can be perfectly adapted to the individual tooth color. Even for a person skilled in the art, it then becomes difficult at first sight to identify the crowned or inserted tooth and distinguish it from the other (true) teeth.
So-called veneers – ie wafer-thin veneer shells – are usually made of ceramic as well. These are glued directly to the teeth to compensate for visual blemishes. This cosmetic procedure is chosen especially when individual teeth stand out in color or have a different shape.
Dentures Made Of Plastic
Plastic is the second choice as a denture material. It wears off faster and can discolor. There are no convincing high-performance plastics for permanent dentures, such as crowns. Thus, plastic is usually used as a temporary for the transitional period or for cost reasons (eg Kunststoffverblendkrone).
