NCT02340663

Brief Summary

Clinical trials of bite splint use and night time tooth grinding have not been performed. Consequently, there are no definitive outcome measures or efficacy standards that can be applied to large clinical trials. The present preliminary trial will determine what objective measures can be used to evaluate efficacy. The outcome variables will fall into four categories: (1) fabrication efficacy, (2) compliance, (3) functional efficacy, and (4) user satisfaction. The immediate goals will: (1) focus on the over-the counter SOVA night guard, (2) conduct tests under controlled clinical conditions using the 'gold standard', the acrylic 'bite splint' or 'orthotic', hereafter called the "Michigan bite splint", to compare the performance and efficacy of the SOVA night guard. Subsequent studies will be able to use the outcome variables identified in this study for broader clinical trials. Specific Aim 1. To compare the SOVA night guard to the custom-acrylic Michigan bite splint in clinical laboratory conditions. Hypothesis: There will be no significant differences between the devices in terms of fabrication efficacy, functional efficacy or user satisfaction. Specific Aim 2. To compare the SOVA night guard to the custom-acrylic Michigan bite splint under ecologically relevant conditions, i.e., the home environment. Hypothesis: There will be no significant differences between the devices in terms of compliance or functional efficacy.

Study Arms (2)

SOVA bite splint

EXPERIMENTAL

SOVA Bite splint: Over-the-counter, heat-and-mold bite splint. Investigators evaluate subject self-fabrication, and evaluate fit. Subjects wear splint nightly for one week. Polysomnographic data obtained from one night during the week. Subjects continue to wear splint for 3 months, dairy kept of nightly wear. Polysomnographic data obtained from one night at the end of three months.

Device: SOVA Bite Splint

Michigan Bite Splint

ACTIVE COMPARATOR

Michigan bite splint: Gold standard, custom acrylic bite splint made for subjects. Investigators evaluate fit. Subjects wear splint nightly for one week. Polysomnographic data obtained from one night during the week. Subjects continue to wear splint for 3 months, dairy kept of nightly wear. Polysomnographic data obtained from one night at the end of three months.

Device: Michigan Bite Splint

Interventions

Over-the-counter thermoplastic bite splint blank, heated, molded to fit.

SOVA bite splint

Heat-cured acrylic bite splint fabricated by dentist/dental technician to fit
