Slow palatal expansion rate
WebbSlow palatal expansion generated physiological expansion force compared to strong forces by rapid palatal expansion with some side effects. Satisfied clinical results will be achieved in selected cases. This paper reviews the types of appliance, skeletal and dental changes, and comparison with rapid palatal expansion. Publication types WebbSlow palatal expansion is a procedure to expand the maxillary arch in transverse dimension to correct the constricted maxillary arch with light forces.
