SPECIFIC OBJECTIVES OR HYPOTHESES
NRS, pain
Considering the importance of patients’ well-being, the present study aimed to
evaluate and compare the impact of two types of maxillary expansion appliances
(tooth-bone-borne and tooth-borne) with respect to pain, discomfort, and
functional limitation during the first week of RME activation in growing
patients, by assessing pain (NRS) and functional limitation (MFIQ). Since the
Hybrid Hyrax is a new appliance, the literature on its symptomatology is scarce.
Although this appliance has shown promising results, it involves a more invasive
technique than traditional appliances, then it is necessary to understand more
broadly its impact. The null hypothesis tested was that there would be no
difference for the pain and discomfort impact between these appliances.
