The inhibiting effect of oral appliance with contingent vibratory stimulus on teeth grinding

Not Applicable

• Conditions: Sleep Bruxism; D020186

• Registration Number: JPRN-jRCTs032190225
• Lead Sponsor: Takaba Masayuki

Brief Summary

There were significant differences in the number and duration of SB muscle activity per hour between subjects with and without vibration, suggesting that vibration stimulation may suppress SB muscle activity. In addition, it was suggested that vibration stimulation may not interfere with sleep. In additon, the splint occlusal surface is worn by SB, and the amount of wear may be quantified.
