Application of addition-cured silicone denture relining materials to adjust mouthguards

Abstract

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.

Mouthguards in dentistry: Current recommendations for dentists

“…56 If the mouthguard is damaged in any way, the dentist should evaluate the cause of the damage/breakage, as well as its condition, to determine whether a new mouthguard is required, as highlighted in Table 3. 59 Since oral appliances have been shown to decrease the athlete's overall oral health, the dentist can implement combative measures such as topical agents. 26,27,55 Such agents include chlorhexidine, fluoride, and casein.…”

“…TA B L E 4 Patient Instructions. [1][2][3]17,21,26,27,30,56,57,59 Choosing a Mouthguard -Athletes should choose a mouthguard that fits snugly on their teeth and covers the gingiva and extends to the posterior teeth (should check all boxes for good condition in Table 3) -The mouthguard should not impede speech and the patient should be able to breathe easily -Patient may want a mouthguard with a strap to attach to their helmet for sports such as American football Caring for the Mouthguard -Mouthguard should always be stored in its carrying case -After every use, both the case and mouthguard should be cleaned with a suitable antibacterial solution, such as a dissolving tablet used for cleaning dentures. Mouthguard and case should then be brushed with a soft toothbrush and rinsed in cool to lukewarm water.…”
