Metals on dental scrap
In order to be used for dental implants like crowns and bridges, metals need to have some specific properties among which biocompatibility, strength, and corrosion resistance are at the top. Separately, metals and noble metals hardly meet these requirements, so they are mixed with each other, creating alloys that bring up their stronger characteristics and can therefore be used in dental appliances.
Metals were first used in dentistry back in the 7th century BC when Etruscans used ivory and gold-covered bone as the core of teeth. Evidence was found then that around the year 300 BC, Romans used gold as artificial teeth, setting the precedent for today’s gold crowns. But it wasn’t until the 1800s that metallic substitutes of teeth were made by pressing different metals like aluminum, gold, platinum, and silver.
Even though metals have been a part of dental appliances for centuries, the precision technologies to cast were only introduced at the beginning of the 20th century. Soon after that, casting technologies progressed rapidly. Noble metals were primarily used because of their low reactivity, but in the 1970s, titanium implants were successfully cast, and a new trend towards non-precious metals containing crowns and bridges started.
However, in the late 1970s, palladium was established worldwide as a favorite metal in the dental industry. Palladium has excellent biocompatibility, corrosion resistance, and a great range of solubility with many metals, which make it ideal for dentistry. It was mainly combined with gold, which made alloys stronger, harder, and more resistant to corrosion and tarnishing. It also has a great bleaching effect, so that as little as 10% of palladium in an alloy made its appearance more silver-colored than yellowish.
We are mentioning palladium because it was widely used in the dental industry, and therefore it is present today in dental scrap, yet not many people know about it and it gets ignored nowadays because it can’t be recognized by the naked eye. The current palladium price is $1000 higher than gold, so this dental scrap can be a hidden treasure.
As we mentioned earlier, dentistry rarely uses pure metals given that they don’t meet the required characteristics. For example, palladium by itself has a too high melting point, pure gold isn’t hard enough, and silver oxidizes easily, which makes them not suitable for the oral environment. Hence these precious metals are mixed between them or with other non-precious metals. But in the 1950s, a new technique was introduced: porcelain fused to metal. Porcelain jackets were used before that to rebuild missing teeth, but they tend to crack very easily, yet the bond between the metal and porcelain prevented stress cracks. These porcelain-fused-to-metal, or PFM, crowns and bridges use precious metals that can still be recovered from dental scrap by the process of refining.
Although these PFM implants are the most popular these days and the dentistry industry trend goes towards metal-free restorations, pure metal appliances are the only clinically long-term proven material in dental medicine.
While nowadays the dental industry is using fewer metals, the older crowns and bridges containing lots of precious metals are being replaced with newer ones, and therefore becoming dental scrap. This dental scrap can be recycled to recover all these valuable materials, and generate considerable money when entrusted to the right refiner.
