Silver amalgam, which was brought to the US in the 1830s was the first dental filling. The amalgam, along with other materials, were used between 1840 and 1850 for filling teeth either damaged or decayed.
Many of these fillings were left in place for years and became subject to various complications, such as infection, corrosion and the dissolution. In 1853, a poisoning caused by mercury patient died when a filling was taken off. However, by the time the 1870s arrived it was silver amalgam that was the most popular choice for fillings. The 1880s saw the first time that amalgam fillings were replaced by gold fillings that continued to be utilized until the 1950s.
When amalgam was the substance used in the 19th century, dental fillings weren’t considered as a solution that was permanent. The sealants for the dental, which help protect teeth from invading the tooth and decrease the risk of infection, have made it clear that dental fillings are only permanent and may require replacing. The 1920s saw the first time that dental products improved greatly and the outcome was that people began to accept fillings , as well as various dental procedures as long-lasting solutions.
Orthodontics
Friedrich Wilhelm von Escherich (German orthodontist) invented the first disposable appliance for correcting underbites and too many in the 1840s. The appliance was made up of a rubber band that was joined to the arch by screws. Additionally, it included an iron band as well as a rubber headband.
The invention was not patent-worthy, however, Escherich introduced several modifications. Escherich also developed an elastic brace that had the springy action, which could be used for correcting underbites. The work of Escherich was first revisited in 1885 by Alfred Angle, an Austrian dentist who started using braces with a number of patients. Angle wrote a piece regarding the issue in the Journal of the American Dental Association. Max Schi used Escherich’s methods.
