Soft mouth guards are effective to prevent traumatic injury in the maxillofacial region. In this study, we tried to find out the effect of soft mouth guards on the distribution and the magnitude of occlusal force using the T-Scan system. Ten adult subjects volunteered to exert maximum biting force wearing three different types of soft mouth guards. With the limitation of the T-scan system reported in our previous article, following results were obtained. 1) Occlusal forces were more evenly distributed with soft mouth guards than without them. 2) Softer mouth guards were more effective for occlusal force distribution. 3) Since occlusal relationship between mouth guards and mandibular arch could alter the distribution pattern a great deal, occlusion of mouth guards should be examined more carefully.
软质口腔护具对预防颌面区域的创伤性损伤有效。在本研究中，我们试图使用T-Scan系统来探究软质口腔护具对咬合力分布及大小的影响。十名成年受试者自愿佩戴三种不同类型的软质口腔护具并施加最大咬合力。鉴于我们之前文章中所报道的T-scan系统的局限性，得到了以下结果。1）佩戴软质口腔护具时咬合力分布比不佩戴时更均匀。2）质地更软的口腔护具在咬合力分布方面更有效。3）由于口腔护具与下颌弓之间的咬合关系会极大地改变分布模式，因此应更仔细地检查口腔护具的咬合情况。
