[Study of occlusal force on female open bite patients with temporomandibular disorders].
OBJECTIVE
To investigate the effect of occlusal force on the etiology of open bite patients who suffer from temporomandibular disorders (TMD).


METHODS
One hundred and two women patients with open bite were divided into TMD (+) group and TMD (-) group according to patients with or without TMD. Occlusal force, occlusal contact areas, occlusal average pressure and occlusal center were evaluated with pressure sensitive sheets. The results were analyzed by SPSS 11.0 statistic software.


RESULTS
Occlusal force and occlusal contact areas in TMD (+) group were significantly lower than that in TMD (-) group. Occlusal average pressure and occlusal center had no significance between two groups.


CONCLUSIONS
The results indicate that the decrease of occlusal force and occlusal contact areas may have some relationships with TMD in open bite patients.
