Micro ‐anatomical responses in periodontal complexes of mice to calibrated orthodontic forces on the crown

ConclusionsThis novel approach illustrates the importance of 3D‐imaging and analysing 3D alveolar socket subjected to OTM otherwise omitted by 2D micrographs. A measured force on the crown elicits a response related to narrowed and widened regions in the 3D complex. OTM that exceeds PDL‐space can illicit biological responses that attempt to restore physiologic PDL‐space via remodelling of the periodontium. Regenerated weaker bone due to aseptic inflammation caused by orthodontics could leave patients at a higher risk of bone loss or root resorption if they later develop periodontitis, a form of septic inflammation.
