Different hyrax expanders for rapid palatial expansion in adolescents with posterior cross-bite
An original research
Keywords:
posterior cross-bite, hyrax expanders, adolescentsAbstract
The posterior cross bite ranges between 10% and 15%. Hence we aim to compare different hyrax expanders for rapid palatial expansion in adolescents with posterior cross-bite. We compared 30 adolescents aged 11 to 16 years, with posterior crossbite, equally divided to groups, Mini Hyrax group and Hyrax group. Dental effects, Impact on quality of life was assessed with the OHIP-14 questionnaire, VAS were compared. We observed that no significant differences in dentoalveolar effects, OHIP-14, pain perception between groups. Considering intra-group comparison, the reduction in pain perception among adolescents in the Mini Hyrax group was gradual. Among adolescents in the Hyrax group, a statistically significant reduction between 48 and 72 h was observed. We can conclude that there was no significant difference in dental effects, impact on quality of life and pain perception between adolescents wearing Mini Hyrax and Hyrax expanders in rapid palatal expansion.
