Management of craniomandibular disorders


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:




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
