[Experimental study on the microcosmic changes of compressed premaxillary suture with laser scanning confocal microscopy].
OBJECTIVE
The aim of this experiment is to know whether active orthopedic appliance is rationale to do presurgical treatment and seek some regularities.


METHODS
Laser scanning confocal microscopy and triple fluorochrome labeling in bone were used to observe and study detailed changes occurred in compressed suture systematically.


RESULTS
Widened suture and broken fibres between the adjoining bones was observed at the 3rd week postoperatively. At the 3rd week hyperplasia of organic tissue components was also seen. At the 6 and 9th week there were no apparent differences among all groups no matter whether in control group or experimental groups.


CONCLUSIONS
Retarding injury of compressed suture and surrounding tissue hyperplasia exists. With growth and development wounded suture will gradually assimilate to control group structurally and functionally.
