Abstract

Abstract

Objective To explore the use of digital technology to intervene in the precise force stimuli for labial high positioned maxillary canines before the orthodontic treatment so as to improve alveolar crest absorption. Methods 54 maxillary labial low canine teeth from 43 adult orthodontic patients were included and divided into an intervention group and a non-intervention group. The distance between cemento-enamel bone junction and alveolar crest （CEJ-AC） before and after the treatment and other relevant data were statistically analyzed. Results 1. There was no statistical difference of CEJ-AC between the intervention group and the non-intervention group before the treatment; After the treatment, the CEJ-AC in the intervention group was lower than that before the treatment （P < 0.05）, and there was no statistical difference of the CEJ-AC in the non-intervention group . 2. Before and after the treatment, there was no statistical difference in the changes of CEJ-AC in patients with thin gingival biotype, but decreased in patients with thick gingival biotype in the intervention group （P < 0.05）. 3. The CEJ-AC decreased after the fixed orthodontic therapy intervention group （P < 0.05）, and the difference between CEJ-AC before and after the treatment was greater than that in the conventional correction group （P < 0.05）, while the reduction value of CEJ-AC of the invisible intervention group after the orthodontic therapy was greater than that in the conventional correction group （P < 0.05）. Conclusion Pre-treatment intervention appliance with digitally designed for labial high maxillary canines can improve alveolar crest absorption after the orthodontic treatment in patients with thick gingival biotype. However, there are no significant effects on thin gingival biotype. Interventions prior to fixed or invisible correction are both effective.
