DEVICE FOR SIMULATION ankylosis of the temporomandibular joint in animal experiments

摘要

The invention relates to the experimental medicine, in particular, to stomatology and may be used to obtain the model ankylosis temporomandibular joint (TMJ) in an animal experiment.; An apparatus comprising Solid metal crowns on oppositely disposed canines wherein said buccal side surface perpendicular to crowns crowns rigidly fixed segments rod 6 mm in length and 2-3 mm in diameter, threaded on rods wearing plate 3 mm thick, provided with a longitudinal axis near the openings through which the plate to provide for this mouth opening width mounted on the rod by a pair of nuts with lock washers.; The device provides a fixed restriction of movement of the mandible in the vertical, sagittal and transverzalnoy planes under the experimental conditions in animals securely fixed on the abutment teeth in the oral cavity by means of integrally cast metal crowns on the upper and lower jaws, can be easily removed, allowing for radiographic and manual control mandibular movements amplitude during and after the experiment. The device is easy to manufacture by molding, does not cause pain and does not injure the surrounding tissues, provides a model of ankylosis of the TMJ is twice faster than the limitation of mobility of the lower jaw from the animal to work procedure of orthopedic treatment of ankylosis, habitual dislocation of the TMJ patients and recommended for further development of tactics of treatment of TMJ disorders.
