Objective:
To observe the movement of rat's tooth in the area of defective alveolar bone filled with bioglass in comparison with contralateral tooth.
Methods:
Forty female Wistar rats were selected. Defects in alveolar bones were created and filled with bioglass. Orthodontic appliances were fixed to mesially guide the maxillary first molars.
Results:
The rats' teeth were mesially moved in the area filled with bioglass. There were no significant differences between two sides in movement distance of the first molars and in thickness of periodontal tissues with paired t-test (P > 0.05).
Conclusions:
The rat's tooth can be mesially moved in the area filled with bioglass.
