“…9-12 A custom-made MG is considered to be more protective and to offer better wearability than the other types. 15,[17][18][19] Various protocols have already been proposed to evaluate impact performance such as tests on samples, 20,21 on sheets 18,19,[22][23][24] 14 Therefore, all types of MG have to be approved for the highest level of protection for a reasonably foreseeable risk during use.…”

“…The reliability and superiority of such a combined measurement system was already well documented in previous studies 29,30) . Low pressure two-sheet type (LW) and medium pressure mono-sheet type (MS) Prescale films were used to measure peak stress levels ranging from 2.5 to 10 MPa and 10 to 50 MPa respectively.…”

The aims of the present study were to investigate the shock absorption capability and force dispersion effect of mouthguard (MG) materials using load cell and film sensors. Two kinds of MG materials, ethylene vinyl acetate and polyolefin, were chosen for this study. When impact forces of approximately 5,000 N were applied on the MG materials using a round flat-nosed rod and a bluntly pointed rod, peak intensities were measured using the load cell sensor while peak stresses and impressed stress distribution areas were measured using the film sensor. Combined analysis using both load cell and film sensors clearly showed the shock absorption properties and force dispersion effects of different MG materials with different impact object shapes. Therefore, impact analysis involving a combined use of these sensor systems was useful and reliable in assessing the shock absorption capability and force dispersion effect of MG materials.

“…Numerous studies have investigated the impact absorption properties of mouthguard materials, but these results cannot be directly compared because of differences in experimental systems. As Reza et al found that the load cell system detected changes in overall transmitted impact force more effectively than film sensor systems, we selected the load cell system for the present study 22) . The free-falling ball impact test method used in the present study was adopted from a previous study 20) in order to allow comparison of data for various mouthguard materials (EVA-, polyolefin-and polystyrene-polyolefin copolymer-based sheets).…”

“…In addition, the MIF-t was 1.15-1.18-fold longer (commercial mouthguard sheets) and 1.03-1.32-fold longer (dental silicone materials) than that of the control group. Reza et al reported that the load absorbance of commercial mouthguard sheets was 24-37% of control MIF 22) . We previously reported that the load absorbance of various commercial mouthguard materials was 26-37% when compared to the control group with regard to MIF, and MIF-t of the commercial mouthguard sheets was 1.26-to 1.59-fold longer than that of the control group 20) .…”

The purposes of this study were to examine the shock absorption capability of addition-cured silicone denture relining materials and the bonding strength of addition-cured silicone denture relining materials and a commercial mouthguard material to determine its applicability to mouthguard adjustment. Two addition-cured silicone denture relining materials and eleven commercial mouthguard materials were selected as test materials. The impact test was applied by a free-falling steel ball. On the other hand, bonding strength was determined by a delamination test. After prepared surface treatments using acrylic resin on MG sheet surface, 2 types of addition-cured silicone denture relining materials were glued to MG surface. The peak intensity, the time to peak intensity from the onset of the transmitted force and bonding strength were statistically analyzed using ANOVA and Tukey's honest significant difference post hoc test (p<0.05). These results suggest that the silicone denture relining materials could be clinically applicable as a mouthguard adjustment material.
