[A longitudinal research on palate growth in the normal mixed dentition by three-dimensional image analysis].
OBJECTIVE
To investigate the trait of the palate growth and to provide a method of three-dimensional image analysis on revealing the entire variation of palate.


METHODS
A longitudinal study on the palate growth of 30 subjects (male 8, female 22) with normal occlusion during mixed dentition was carried out by three-dimensional image analysis. The observation period was from 7 to 10 years of age.


RESULTS
During growth, the palate vaults in 16 cases (53%) descend for 1-5 mm, whereas, the palate vaults in 14 cases (47%) ascend for 2.6 mm at most.


CONCLUSIONS
The variations of palate growth can be investigated by three-dimensional image analysis. During growth, the palate vault may descend or ascend, which shows the individual differences of oronasal function.
