A Modified Hyrax-Type Expander Is Effective for Distal Bodily Movement of the Maxillary First Molar

Applied Sciences, 2022
Impaction and eruption disturbance of permanent teeth are frequently encountered in orthodontic practice. The canine teeth play an important role both functionally and esthetically. Eruption disturbance of a maxillary canine, if left untreated, can cause
