About this study
Official title: Effect of Low-Level Laser Therapy Versus CAD/CAM Michigan Splint on Patients With Temporomandibular Muscle Disorders Randomized Clinical Trial
This study aimed to evaluate the sustainability of the efficacy of using low level laser therapy and CAD/CAM Michigan splint in improving the range of mandibular movements, muscle activity and reducing the pain.
Read the detailed description
56 female patients were randomly divided into two groups, Group A: Patients received applications of low-level laser therapy using semiconductor InGaAsp diode LASER type 940 nm with continuous mode of operation, with time of application 180 sec per session for 12 sessions. Group B: Patients received hard occlusal splints (Michigan splints) of 2 mm thickness constructed on their upper teeth, the hard occlusal splint was 3D digitally printed. ARCUS digma facebow was used to evaluate the range of mandibular movements affected from TMJ problems. The opening measurements of the patient were taken using a millimeter ruler. Electromyogram (EMG) was used to evaluate muscle activity. Visual analogue scale (VAS) was used to evaluate the pain intensity. All was done before the beginning of the treatment at three and six months follow up period.

The increase in the range of movement measured using ARCUS digma in terms of angular inclination.
Measured: Measured 3 times through 6 months from the beginning of the treatment. (0,3,6 months)
Secondary outcomes (2)
Pain intensity
The degree of pain is assessed using a 10 cm scale (VAS)

Mouth opening
degree of mouth opening in cm using ruler
Measured: Measured 3 times through 6 months from the beginning of the treatment. (0,3,6 months)

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Electromyographic muscle activity (time frame: Measured 3 times through 6 months from the beginning of the treatment. (0,3,6 months)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 13 Jun 2023; AzTrials last refreshed its copy on 8 Nov 2026.
