Voxel\u2010based superimpositions of the T2 and T3 images were performed, and the distances of incisal and apical movement between T2 and T3 were measured to determine whether relapses occurred.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>After orthodontic treatment, the labial and lingual (palatal) bone height decreased significantly (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.05) and the labial thickness at the crestal (L1), midroot (L2), and apical levels (L3) had no significant change, while the lingual (palatal) bone thickness at all three levels decreased significantly (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.05). After 18\u201024\u00a0months of retention, the lingual (palatal) height and the lingual (palatal) thickness at the crestal (L1) level increased significantly (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.05).

Therefore, appropriate camouflage treatment can be used in patients with bimaxillary dentoalveolar protrusion, and this treatment will not irreversibly deteriorate periodontal health and affect the orthodontic treatment
