Design outcomes
Primary
| Measure | Time frame |
|---|---|
| - Pain during mandibular movement or function using the VAS | — |
Secondary
| Measure | Time frame |
|---|---|
| - Pain perceived by the patient at rest using the VAS - Maximum Interincisal Opening (MIO; in mm) without perceiving (increased) pain measured by the clinician - MIO (in mm) measured by the clinician - Mandibular range of motion (MROM) measured by the clinician (proal and lateral movements; in mm) - Joint blocks and noises (i.e. clicks, crepitation, pops) perceived by patient in last 3 months (absent/ present) - Impairment of mandibular function as perceived by patient using the validated mandibular function impairment questionnaire (MFIQ; 17 items scored on a Likert scale, with the total score ranging 0-68) - Cost-effectiveness (using the composite of the primary study outcome variable *VAS-score during movement or function* and *costs*, and a second cost-effectiveness analysis using *MFIQ-score* and *costs*) - Safety (qualitatively and quantitatively measured adverse and serious adverse events) | — |
