Abstract EN
Orthodontic tooth movement (OTM) is the result of region-specific bone modeling under a load.
Quantification of this change in the alveolar bone around a tooth is a basic requirement to understand the mechanism of orthodontics.
The purpose of this study was to quantify subregional alveolar bone changes during orthodontic tooth movement with a novel method.
In this study, 12 Sprague-Dawley (SD) rats were used as an orthodontic model, and one side of the first upper molar was used to simulate OTM.
The alveolar bone around the mesial root was reconstructed from in vivo micro-CT images and separated from other parts of the alveolar bone with two semicylinder filters.
The amount and rate of OTM, bone mineral density (BMD), and bone volume (BV) around the root were calculated and compared at 5 time points.
The results showed that the amount of tooth movement, BMD, and BV can be evaluated dynamically with this method.
The molar moved fastest during the first 3 days, and the rate decreased after day 14.
BMD decreased from day 0 to day 14 and returned from day 14 to day 28.
BV deceased from day 0 to day 7 and from day 14 to day 28.
The method created in this study can be used to accurately quantify dynamic alveolar bone changes during OTM.
