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.

最近，在日本，参加体育运动的人数正在增加，这可能是由于荒地意识提高。他们也越来越意识到可能的运动损伤。尽管对口腔区域的伤害的担忧低于身体其他部位，但在进行适当的运动时，有很多人穿着商业上可用的口腔护卫。这些事情表明，定制的口罩的可用性不足以理解。在这项研究中，我将定制的口罩与市场上的定制口罩进行了比较。他们戴着商业扬口警卫和定制的一名，每个人都持续了3个月；以及测量了1个月后和3个月后，咬合状况和重力波动的变化。市场上的口罩是由口腔形成的类型，定制的是由座椅压力方法制成的，厚度为3mm，覆盖了前齿的零件。结果，总咬人没有变化武力或接触区域被任何一个警卫确认。使用商业扬口后卫，使用后1个月后重力波动的距离低于佩戴后卫后发现的重力波动。对于定制的口腔护罩，使用后1个月后的重力波动的距离低于戴口罩后的距离，并且发现了显着差异。
