Abstract

There is a growing need for a mouthguard sheet material with higher shock absorption and dispersion capacity than those obtained by conventional materials. A five-layer mouthguard sheet material was previously developed using laminated ethylene vinyl acetate and polyolefin copolymer resin. In this study, the shock absorption capacity and dispersion capability of the new sheet material were investigated and compared with those of other materials. Impact testing for the new sheet material showed that the force required to displace the sheet by 1 mm was significantly higher at all thicknesses (p<0.001), whereas the puncture energy and displacement were significantly lower than those for ethylene vinyl acetate (p<0.05). The five-layer mouthguard sheet material successfully absorbed and resisted shock. Therefore, the sheet material potentially increases resistance to applied deformation in teeth and alveolar bone and maintains structure. The five-layer sheet material could expand the range of mouthguard products and help prevent oral trauma.

新型五层护齿片材料的减震和分散能力

与传统材料相比，人们越来越需要一种具有更强减震和分散能力的护齿片材料。以前曾使用层压乙烯-醋酸乙烯和聚烯烃共聚物树脂开发出一种五层护齿片材料。在这项研究中，对新型片材的冲击吸收能力和分散能力进行了调查，并与其他材料进行了比较。对新型片材的冲击测试表明，使片材位移 1 毫米所需的力在所有厚度上都明显较高（p<0.001），而穿刺能量和位移量则明显低于醋酸乙烯酯（p<0.05）。五层护齿片材料成功地吸收和抵抗了冲击。因此，护齿片材料有可能增加牙齿和牙槽骨的抗外力变形能力，并保持结构。五层护齿片材料可以扩大护齿产品的范围，有助于预防口腔创伤。

期刊介绍： Dental Materials Journal is a peer review journal published by the Japanese Society for Dental Materials and Devises aiming to introduce the progress of the basic and applied sciences in dental materials and biomaterials. The dental materials-related clinical science and instrumental technologies are also within the scope of this journal. The materials dealt include synthetic polymers, ceramics, metals and tissue-derived biomaterials. Forefront dental materials and biomaterials used in developing filed, such as tissue engineering, bioengineering and artificial intelligence, are positively considered for the review as well. Recent acceptance rate of the submitted manuscript in the journal is around 30%.
