Remote Corticotomy Accelerates Orthodontic Tooth Movement in a Rat Model

Figure 3

Corticotomy increased Osteocalcin expression in the periodontal tissue on the tension side of the orthodontic teeth. The immunofluorescent staining of osteocalcin (OCN) in the periodontal tissue around the distal surface of the distal buccal root of orthodontic teeth on day 3, day 7, day 14, and day 28. Larger staining positive area was noticed in the Corticotomy + OTM group at day 7, day 14, and day 28 when compared to that in the OTM group. B: alveolar bone; P: periodontal ligament; T: tooth. Scale bar = 100 μm.
