Management of craniomandibular disorders





1. Intra-articular ligaments of the temporomandibular joint are:


Lig. temporomandibulare laterale


Lig. disco-temporale


Lig. disco-condylare


Lig. spheno-mandibulare



2. As masticatory (chewing) muscles are considered:


M. masseter, pars profundus and pars superficialis


M. temporalis, pars anterior and pars posterior


M. pterygoideus medialis, pars anterior and pars posterior


M. pterygoideus lateralis, pars inferior, pars intermedius and pars superior



3. The anterior temporomandibular joint capsule shows attachments with:


Discus articularis


Os temporale, anterior of the tuberculum or eminentia articulare


Condylus mandibulare


M. pterygoideus lateralis, pars superior



4. Typical physiological characteristics of the discus articularis of the temporomandibular joint are:


Three-dimensional biconcave hat shaped


The posterior border is in the vertical line on top of the head of the mandible or slightly anterior (11 or 12 o’clock position) and shows two ligamentous attachments


Designed for equilibration and suspension between the fossa of the temporal bone and mandibular head in all positions of the mandible


Can move over the mandibular head passively; muscular activity is not required



5. Excursive movements of the temporomandibular joint are:


Depression


Elevation


Protraction


Lateral movements



6. Physiological characteristics of depression (mouth opening) are:


Average range of motion measured between the incisives is 36–50 mm, including overbite


Average range of motion measured between the incisives is equal with the width of two fingers of the same person


Condylar rotation along a frontal axis during initial depression (arthrokinematics of the lower joint compartment)


Limited mouth opening is related with the occurrence of mental depression



7. The temporomandibular joint differs from most other synovial peripheral joints in the human body by:


The temporomandibular joint never develops degenerative changes


The head of the mandible has fibrous cartilage


The left and right joints have one common distal joint partner


Teeth contribute to movement behaviour, movement guidance and resting position of the joint
