Mouth guards are effective to prevent traumatic injury in maxillofacial region during sports activities. This study was conducted to investigate the influence of wearing mouth guards on occlusal force distribution with the T-scan system. With comparison to the value of average occlusal force level per occlusal point (OFL) on natural dentition and wearing conventional full arch bite plane, following results were obtained. 1) Difference of OFL within the same dental arch became smaller when mouth guards were on. 2) Statistically significant difference in OFL was not found between two mouth guards with different hardness. 3) During three seconds clenching, OFL in posterior region changed great deal at the initiation but stayed at about the same level after that.
护齿器在体育活动中对预防颌面区域的创伤性损伤是有效的。本研究旨在用T扫描系统调查佩戴护齿器对咬合力分布的影响。与天然牙列和佩戴传统全牙弓咬合平面时每个咬合点的平均咬合力水平（OFL）值相比，得到了以下结果。1）佩戴护齿器时，同一牙弓内的OFL差异变小。2）在两种硬度不同的护齿器之间未发现OFL有统计学上的显著差异。3）在三秒紧咬过程中，后部区域的OFL在开始时变化很大，但之后保持在大致相同的水平。
