Measurement of the Temporomandibular Joint Disc Movement during Mouth Closure

Popis výsledku v původním jazyce

The main aim of this work was to determine the relative displacement of the temporomandibular (TM) disc and the mandible during mouth opening and closure. While the movement of the mandible has already been published, though only for a small mouth opening, the behaviour of the disc during the same movement has not been well depicted. The movement of the TM disc was studied using a magnetic resonance imaging (MRI). Six sagittal static images in revolved sections of the temporomandibular joint (TMJ) wereobtained in various positions of jaw opening from 0 to 50 mm. The head was fixed to avoid major displacements; smaller displacements of the head were corrected using the geometric transformation. The results provided a description of the TM disc displacements as a function of jaw opening. The maximum displacements of the mandible and TM disc were about 31 mm and 18 mm respectively at mouth opening of 50 mm. The maximum rotation of the mandible was 34.4&ordm;.
