Comparison of Two Tooth-borne Expanders in Rapid Maxillary Expansion
This study will assess the dentoalveolar effects and impact on quality of life of two types of maxillary expanders in orthodontic patients with permanent dentition, from 12 to 16 years old. Half of participants will be treated using the Hyrax expander, while the other half will use the mini Hyrax expander. The null hypothesis is that there is no difference between dentoalveolar effects and impact on quality of life of the two protocols.
