Abstract EN
The aim of this animal study was to develop a model of orthodontic tooth movement using a microimplant as a TSAD in rodents.
A finite element model of the TSAD in alveolar bone was built using μCT images of rat maxilla to determine the von Mises stresses and displacement in the alveolar bone surrounding the TSAD.
For in vivo validation of the FE model, Sprague-Dawley rats (n=25) were used and a Stryker 1.2 × 3 mm microimplant was inserted in the right maxilla and used to protract the right first permanent molar using a NiTi closed coil spring.
Tooth movement measurements were taken at baseline, 4 and 8 weeks.
At 8 weeks, animals were euthanized and tissues were analyzed by histology and EPMA.
FE modeling showed maximum von Mises stress of 45 Mpa near the apex of TSAD but the average von Mises stress was under 25 Mpa.
Appreciable tooth movement of 0.62 ± 0.04 mm at 4 weeks and 1.99 ± 0.14 mm at 8 weeks was obtained.
Histological and EPMA results demonstrated no active bone remodeling around the TSAD at 8 weeks depicting good secondary stability.
This study provided evidence that protracted tooth movement is achieved in small animals using TSADs.
