| Outline of Final Research Achievements |
Destructive alveolar bone resorption may be occurring by orthodontic tooth movement under diabetic hyperglycemia. The aims of this study were, to know the 3-dimensional alveolar bone resorption rate by orthodontic treatment under hyperglycemia, to know optical orthodontic force in such cases, and to know if the Low-Intensity Pulsed Ultrasound could recover this absorbed alveolar bone effectively.
The results could conclude that destructive alveolar bone resorption was occurred in hyperglycemia condition compared to normal condition in rats, and the Low-Intensity Pulsed Ultrasound could formate faster bone absorption.
