The purposes of this study were to investigate the initial tissue changes on the teeth
and surrounding tissues under contraction and intrusive force by contraction UTA.
A control and experimental dogs, 10-months in age, were studied. Contraction and
intrusive force(60gm) were applied at upper four incisors by contraction UTA.
Experimental dogs were sacrificed at 2 weeks and 4weeks after force application,
respectively. In this study, 2 experimental groups were designed by the duration of force
applied(E1, E2).
The specimens were taken around the upper first and second incisor in each groups
and were prepared for the H-E and MT stain for light microscopic observation.
From the results of the study, the following conclusions may be drown. :
1. In control group, the periodontal ligament width was constant from apical third to
cervical third of the root and periodontal fiber arrangement was horizontal or oblique in
cervical third, oblique in middle third and apical third. In alveolar bond, smooth
appearance was shown with osteoblast.
2. In experimental group 1, in proportion to force was concentrated at labial middle third
and apical third of root of the upper first and second incisors, root of these tooth tipped
labially and intruded at a time.
3. In experimental group 2, periodontal ligament width and arrangement was similar to
control and observed strong calcified response at the labial middle third of root. But,
alveolar bond resorption and cementum resorption were as before seen at labial middle
third and apical third of root force was concentrated.
