目的
本研究的目的是评估实验性有机硅材料 (PM1) 的一些重要机械性能，以评估其作为护齿套材料的潜力。
材料和方法
测定了有机硅材料的硬度、撕裂强度、拉伸性能和能量吸收性能，并与 2 种市售材料（Bioplast，一种聚醋酸乙烯酯聚乙烯和 Polyshield，一种有机硅）进行了比较。
结果
Bioplast 明显比 Polyshield 和 PM1 更硬。 Polyshield 比 PM1 硬得多。 Bioplast 的撕裂强度明显高于 Polyshield 和 PM1。 Bioplast 的拉伸强度明显大于 Polyshield 和 PM1。 PM1 的拉伸强度明显高于 Polyshield。 Bioplast 在 500 N 下的能量吸收能力明显低于 Polyshield 和 PM1，其中 PM1 的值明显高于 Polyshield。在 1,000 和 1,500 N 下，Bioplast 的能量吸收明显高于 Polyshield 和 PM1。
结论
结论是，在较低冲击力下，PM1 表现出比 Polyshield 更好的能量吸收性能，比 Bioplast 更好的能量吸收性能。 PM1 比 Polyshield 更软，并且具有更好的撕裂和拉伸性能。本研究的结果表明，该新材料具有用作护齿套材料的良好潜力。
PURPOSE
The purpose of the present study was to evaluate some important mechanical properties of an experimental silicone material (PM1) to assess its potential as a mouthguard material.
MATERIALS AND METHODS
The hardness, tear strength, tensile properties, and energy absorption properties of the silicone material were determined and compared with those of 2 commercially available materials (Bioplast, a polyvinylacetate polyethylene, and Polyshield, a silicone).
RESULTS
Bioplast was significantly harder than Polyshield and PM1. Polyshield was significantly harder than PM1. Bioplast had a significantly higher tear strength than both Polyshield and PM1. The tensile strength of Bioplast was significantly greater than that of Polyshield and PM1. PM1 had a significantly higher tensile strength than Polyshield. Bioplast had a significantly lower energy absorption capacity at 500 N than both Polyshield and PM1, with PM1 having a significantly higher value than Polyshield. At 1,000 and 1,500 N, Bioplast had a significantly higher energy absorption than both Polyshield and PM1.
CONCLUSION
It was concluded that PM1 showed better energy absorption properties than Polyshield and better energy absorption properties than Bioplast at lower impact forces. PM1 was softer and had better tear and tensile properties than Polyshield. The results of the present study suggest that the new material has a good potential for use as a mouthguard material.
