Charles Stent
From Wikipedia, the free encyclopedia
Charles Stent (1807-1885) was a nineteenth-century English dentist notable for his advances in the field of denture making.
In 1847, Edwin Truman introduced gutta-percha as a material for making dental impressions; however, this was unsatisfactory for several reasons, including its tendency to distort upon removal from the patient's mouth, and to shrink upon cooling. In 1856, Stent added several other materials to the gutta-percha, notably stearine, which markedly improved the plasticity of the material as well as its stability. He also added talc as an inert filler to give more body to the material, and red colouring.
The medical device called a stent derives its name from him.
