In 1820, Samuel Stockton, a goldsmith by trade, began manufacturing high-quality porcelain dentures mounted on 18-carat gold plates. Later dentures from the 1850s on were made of Vulcanite, a form of hardened rubber into which porcelain teeth were set. In the 20th century, acrylic resin and other plastics were used.[12] In Britain, sequential Adult Dental Health Surveys revealed that in 1968 79% of those aged 65–74 had no natural teeth; by 1998, this proportion had fallen to 36%.[13]
Typically, a removable partial denture is made of a metal framework with pink plastic to replace the gum tissue and plastic or resin denture teeth. The number of missing teeth and their location will affect the comfort and stability of the removable partial denture. The use of dental implants may increase the stability of a removable partial denture, or dental implants may be the best solution for replacing the missing teeth.
