Analysis of changes in ABT, ABH and ABA after orthodontic treatment of adult bimaxillary protrusion

Orthodontic treatment is effective in adult patients with bimaxillary protrusion, but significant resorption of the alveolar bone on the palatal side of the incisal region occurs after treatment, reducing the amount of alveolar bone in the entire incisal region. Therefore, the long-term effects on periodontal tissues need to be paid attention to.
