摘要
目的通过对两种制作铸型标本方法的比较,评价各自方法的优劣。方法将ABS与1:1比例的丙酮、丁酮混合液按3:10进行混合溶解;将牙托粉与自凝树脂液按3.5:10比例制成溶液。将上述溶液加入红监染料后分别灌注入6只离体新鲜猪肺动脉和静脉内。再将其置入60％的硫酸中进行腐蚀。结果ABS溶液配制的标本,段级及以上血管完整性的断落率为0％,段以下断落率为14.1％,可以观察至10～12级血管;自凝树脂液对段及以上血管断落率为5.6％,对段级以下断落率为11.8％可以观察至11～12级血管。结论两种铸型标本制作方法在标本断落率及可观察性上无差别,但自凝树脂液制作较为简便。
Purpose To evaluate the advantage and disadvantage of two methods through comparing making cast specimens.Method ABS,acctone and butanone;0# colorless Dissolve the ABS by the ratio of 3:10 with the mixture of acetone and butanone half in each. Compound the solution by tooth powder and self-solidification resin liquid with ratio of 3.5:10. Pour the two solutions added with red and blue dyestuff respectively into arteries and veins of 6 fresh resected pig lungs, respectively. Then put them into 60% sulphuric acid for corrode.Result Broken rate is 0% in sections and above , 14.1% in subsections and below. We can observe to 10-12 orders. Broken rate is 5.6% in sections and above. 11.8% in subsections and below;We can observe to 9- 12 orders.Conclusion There is no statistic difference between the two methods in broken rate and observability, bur the solution of self-solidification resin is convenient comparatively.
