About this study
Evaluation of the efficacy of the occlusal appliance with active cannabidiol (CBD) molecules in TMD patients
Read the detailed description
Occlusal appliance therapies are used in TMD patients. In this research the active CBD molecules will be released from the occlusal appliance during nighttime, in population of patients suffering from TMD. The effectiveness of the myorelaxation (sEMG of mastcatory muscles activity) and analgesic effect( VAS analysis) of occlusal appliance with the CBD molecules will be compared to the traditional acrylic-resin material used so far for occlusal appliance manufacture. The aim of the research is the evaluation of the innovative material effectiveness, used for the production of the occlusal appliance.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing CBD occlusal appliance and Acrylic resin occlusal appliance in people with Temporomandibular Disorder and Myofascial Pain, run by Medical University of Silesia at 1 site in Poland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 1 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Aleksandra Nitecka-Buchta, Adiunct (601899069, aleksandranitecka@poczta.onet.pl), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Reduction of sEMG activity of masseter muscle (time frame: 40 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04775030, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Mar 2021; AzTrials last refreshed its copy on 30 Oct 2026.
