齿科藻酸盐印模材料的力学性能测试

The mechanical property testing of dental alginate impression materials

藻酸盐材料是一种广泛应用于齿科临床的印模材料。该文利用合适的设备研究了齿科藻酸盐印模材料的力学性能，并比较了不同消毒处理后的材料断裂韧性、压应变以及形变恢复的区别。经实验证明，采用消毒机或紫外线消毒以后，材料的力学性能有所改善。

Alginate material, as one of the impression materials, is widely used in dental clinic. Proper equipment was applied to test the mechanical property of dental alginate impression materials. Fracture toughness, deformation recovery and compression strain were compared after different sterilization methods. The results indicate that the mechanical property was improved by sterilizing machine or ultraviolet treatment.
