Evaluating and comparing the short term effects of different palatal expanders on the amount of palatal expansion and buccal tipping of posterior teeth.
Hypothesis:
H0: There is no difference in the short term effects between the different palatal expanders.
H1: There is a significant difference in the short term effects between the different palatal expanders.
