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
Stenström technique Stenström technique The Stenström technique or method is otoplastic surgery (otoplasty) for pinning protruding ears. The method belongs together with the Mustardé technique and the Converse technique to the traditional or conventional otoplasties. The technique of this surgery was described by Stenström in 1963 and was slightly altered by him in 1973. This is a plastic surgery of the antihelix that is carried out with the scratch or scoring technique. Underlying this method is the evidence that the cartilage bends itself convexly to the opposite side after scratching or scoring. A long incision is made on the back of the
