Plain-language summary
Objective To compare the effects of botulinum toxin type A (BTX-A) injections, occlusal stabilization splint therapy, and nocturnal overdenture removal on masticatory muscle activity and overdenture retention in patients with sleep bruxism wearing implant-retained mandibular overdentures.
Methods This randomized, single-blind, parallel-group clinical trial allocated patients with definite sleep bruxism to one of three groups (1:1:1): BTX-A injections with nocturnal overdenture wear, occlusal stabilization splint therapy with nocturnal overdenture wear, or nocturnal overdenture removal (control). Electromyographic (EMG) activity of the masseter and temporalis muscles was assessed at baseline and at 3, 6, 9, and 12 months. Overdenture retention was measured at 1, 3, 6, and 12 months using a digital force gauge. Intergroup comparisons were performed using one-way ANOVA with Tukey's post hoc test, and intragroup comparisons using repeated-measures ANOVA (α = 0.05).

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* a confirmed diagnosis of definite sleep bruxism (SB)
* retention of natural dentition in the maxillary dental arch, without missing a single tooth of 6 anterior teeth, with no more than one or two missing premolar or molar teeth per quadrant
* existing implant-retained single overdentures (OD) that had been functionally loaded for at least one year prior to study initiation
Exclusion Criteria:
* had undergone any previous therapeutic interventions for bruxism
* exhibited medical conditions with known impacts on temporomandibular joint (TMJ) function, including (but not restricted to) post-radiation effects, osteoarthritis, or trauma-related pathologies.
* Any contraindication for BTX-A injection such as, allergy, pregnancy, and lactation.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
