Charles Stent Charles Stent Charles Stent (1807–1885) was a 19th-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
Bioresorbable stent and safety profile to drug-eluting stents. Specifically, the Absorb naturally dissolving stent has been investigated in single-arm trials and in randomized trials comparing it to a drug-eluting stent (DES). Early and late major adverse cardiac events, revascularizations, and scaffold thromboses have been uncommon and similar to the Xience DES, a market leader in the drug eluting stent category. Studies in real-world patients are ongoing. Imaging studies show that the Absorb naturally dissolving stent begins to dissolve from six to 12 months and is fully dissolved between two and three years after it is placed in the artery.
