Description
Yewei Xin and five co-authors reported a long orthodontic case fixing an open bite in a 2026 paper. A twenty-two-year-old man had front teeth that did not meet, plus failing first molars. Three molars were removed, and clear aligners dragged the rear molars forward over long spans.
Aligners often struggle with such moves, and the crowns began to tip and drift off track. Long-arm springs fitted as helpers righted the molars and kept roots parallel. After forty-one months and eighty-two aligner sets, the gaps had nearly closed and the bite and profile improved. Root shortening and enamel spots did appear. The authors discuss how to weigh gains against such biological costs in adult protraction work.
