Abstract
To clarify the characteristic of the sideshift of the child at the lateral gliding movement 20 child groups (10 males and 10 females) and 20 adult groups (10 males and 10 females)were used as testees.
Their sideshifts were measured with a measuring assembly for lower jaw movement with six degrees of freedom. The element was obtained and the following conclusions were obtained since the comparison was made separately for the element which moved to purely lateral and the element which moved while rotating with the examinations were performed.
As for the amount of the total sideshift of the significant difference was not found between males and females. The value was 1.82±0.88 mm in the child group and 1.29±0.90 mm in the adult group. The child group clearly indicated a larger value compared with the adult growp.
The rotational transfer element was 0.32±0.07 mm in the child group and 53±0.15 mm in the adult group. The adult group clearly indicated a larger value compared with the child group.
The purely lateral movement element was 150±0.90 mm in the child group and 0.76±0.85 mm in the adult group. The child group clearly indicated a larger value compared with the adult group.
The ratio of the rotational component was 17.8% in the child group and 42.3% in an adult group. In the child groups there were ferer tendencies compared with the adult group.
