Primary Outcome Measures

Name	Time	Method
<p>Study parameters are measured with a so-called mandibular movement recording.<br /><br>Study parameter for TMJ anterior disc displacement is a change in the relative<br /><br>distance (in %) on which joint clicking (i.e. disc reduction) during mouth<br /><br>opening occurs, measured on sagittal condylar traces. Study parameter for TMJ<br /><br>hypermobility is the acceleration of the condyle (in mm/sec2), related to the<br /><br>joint click during mouth closure (i.e. snapping of the condyle along the<br /><br>articular eminence), measured on sagittal condylar traces.</p><br>
