ABSTRACT
Objective:
To investigate the effect of partial p osterior teeth with reverse cross-bite at one side of mandible on the chewing m ovement.Methods:
16 university students with partial posterior teeth reverse cross-bite and 12 with normal occlusion were included, 5 cycles o f gum chewing movement with left and right side separately were recorded with K6 -Ⅰmandibular kinesiograph (MKG) for the trace and velocity.Results:
①The chewing movement recorded in frontal plane was with a typical cycl e in controls while that in reverse cross-bite individuals was vertically in an d/or out type (59.38%), as well as in and out in same direction type (21.88%). ②Chewing movement in reverse cross-bite patients was in posterior direction, together with a larger angle of closing trace to horizontal plane and higher che wing terminal velocity.Conclusion:
Partial posterior teeth with reverse cross-bite at one side have significant effect on both direction and v elocity of chewing movement.
