Previous studies into sporting mouthguards have been mainly attitudinal or epidemiological. The aim of the present study was to build an impact rig to measure the impact absorbed by mouthguard materials of various thicknesses. The acceleration of the pendulum of the rig was measured and used to calculate the force transmitted to the materials. Impact tests were also performed on three commercially available mouthguard materials. Tests showed that the force transmitted through mouthguard materials was inversely related to the material thickness. Mouthguard construction techniques with ethylene vinyl acetate (EVA) plastics should be monitored to avoid occlusal thinning especially on the incisal edges. Thinning results in reduction in the protection offered by the mouthguard.
先前对运动护齿器的研究主要是关于态度或流行病学方面的。本研究的目的是构建一个冲击装置，以测量不同厚度的护齿器材料所吸收的冲击力。测量了该装置摆锤的加速度，并用于计算传递到材料上的力。还对三种市售的护齿器材料进行了冲击测试。测试表明，通过护齿器材料传递的力与材料厚度成反比。应监测采用乙烯醋酸乙烯酯（EVA）塑料的护齿器制作技术，以避免咬合面变薄，尤其是在切缘处。变薄会导致护齿器提供的保护作用降低。
