Recently in Japan the number of people participating in sports has been increasing, probably due to increased heath awareness; and they are also becoming more conscious of possible sports injury. Although concern about injury to the oral area is lower than that to other parts of the body, there are many people who wear a commercially available mouth guard when engaging in sports for which one is appropriate. These things show that availability of custom-made mouth guards doesn't understand sufficiently. In this study, I compared custom-made mouth guards with those on the market with respect to the occlusal condition and gravity fluctuation.The subjects were 20 adults who had never used a mouth guard in some kind of sports. They wore the commercial mouth guard and the custom-made one, each for 3 months; and the changes in occlusal condition and gravity fluctuation just after the start of wearing the mouth guard, after 1 month, and after 3 months were measured. The mouth guard on the market was of the mouth-formed type, and the custom-made one was made by the seat pressure method and had a thickness of 3mm in the part covering the front teeth.As the results, no change in total biting force or contact area was recognized with either guard. With the commercial mouth guard, the distance of gravity fluctuations after use for 1 month was lower than that found just after the start of wearing the guard. In the case of the custom-made mouth guard, the distance of gravity fluctuations after use for 1 month was lower than just after wearing of mouth guard, and a significant difference was recognized.

近年来，日本参加体育运动的人数不断增加，这可能是由于健康意识的增强；他们也越来越意识到可能的运动损伤。尽管对口腔区域伤害的担忧低于对身体其他部位的伤害，但仍有许多人在进行适合的运动时佩戴市售护齿套。这些都表明人们对定制护齿套的了解还不够充分。在这项研究中，我将定制护齿套与市场上的护齿套的咬合状况和重力波动进行了比较。研究对象是 20 名从未在某种运动中使用过护齿套的成年人。他们佩戴商用护齿套和定制护齿套，各佩戴 3 个月；测量刚开始佩戴护牙套后、1个月后和3个月后的咬合状况和重力波动的变化。市场上的护齿套为口型，定制的护齿套采用座压法制作，覆盖前牙的部分厚度为3mm。结果，两种护齿套的总咬合力或接触面积均未发生变化。使用商用护齿套，使用1个月后的重力波动距离低于刚开始佩戴护齿套后的重力波动距离。在定制护齿套的情况下，使用1个月后的重力波动距离低于刚佩戴护齿套后的重力波动距离，并且发现了显着差异。
