In this study, we have investigated the relationship between stomatognathic system(including dental occlusal function) and systemic condition(including bone mineral density), and also the usefulness of mouth-protector for elevation of the muscle strength. Nineteen male athletes were participated as volunteer subjects. The following factors of the stomatognathic system were measured ; biting force, biting force valance, gonial angle, and corpus mandibular length. To analyze multiple correlation, there were significant positive correlation (p<O.O1) between corpus mandibular length and bone mineral density, but no correlation between bone mineral density and biting force were observed. The mean occlusal force level after wearing the fitted mouth-protector was greater than before. Significant differences were found between with and without mouth protectors in soleus H-reflex. These data suggest that 1) stomatognathic system (especially corpus mandibular length) should be considered in bone mineral density ; 2) the isometric muscle strength would be increased by biting with the fitted mouth-protector.

在这项研究中，我们研究了口颌系统（包括牙齿咬合功能）和全身状况（包括骨矿物质密度）之间的关系，以及护口器对于提高肌肉力量的作用。十九名男运动员作为志愿者参加。测量了口颌系统的以下因素；咬合力、咬合力、角角和下颌体长度。多重相关分析显示，下颌体长度与骨密度呈显着正相关（p<O.O1），但骨密度与咬合力之间无相关性。佩戴合适的护口器后的平均咬合力水平比之前更大。使用和不使用口腔保护器之间的比目鱼肌 H 反射存在显着差异。这些数据提示：1）骨密度应考虑口颌系统（尤其是下颌体长度）； 2）通过使用合适的护口器咬合，可以增加等长肌力。
