수축과 이완작용이 가미된 치과용 인상재 믹싱팁의 혼합 효율 향상 연구

Mixing tip has many advantage such as minimizing the entry of bubble and mix uniform. However, impression materials remain in the mixing tip because of its disposability. We add esophagus peristalsis on mixing tip and adjusted the location of twist. The form was simulated by COMSOL before the experiment and modeling many kinds of mixing tip by Solid Works to print out using a 3D printer. Then, using Image J confirm degree of mixing uniformity. The result show that the ratio of 2:8 is better than 5:5 in mixing efficiency. With peristalsis effect, we can reduce impression materials by making mixing tip more shorter than existing. We expect that this result can be applied to a micro-fluidic mixing study.
