Experimental study on the microcosmic changes of compressed premaxillary suture with laser scanning confocal microscopy / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>The aim of this experiment is to know whether active orthopedic appliance is rationale to do presurgical treatment and seek some regularities.</p><p><b>METHODS</b>Laser scanning confocal microscopy and triple fluorochrome labeling in bone were used to observe and study detailed changes occurred in compressed suture systematically.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>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.</p>
