Hyrax with rests (HSS2)
Unlike the Hyrax, which is perfect for adults and children with permanent dentition, the Hyrax with rests is recommended for patients with mixed dentition. The bands on the premolars are replaced with rests that are fitted on the occlusal or lingual surface of the primary molars. In order to provide more stability to the appliance, composite material can be used to bond the rests.
