[Effect of complete dentures on the blood flow and blood cell velocity of alveolar mucosal microcirculation]

The Purpose of this study was to determine the effects of complete dentures on alveolar mucosa microcirculation. The alveolar mucosal microcirculation of 17 edentulous subjects was measured by videomicroscope. The variance of the alveolar mucosa microcirculation before and after insertion of the dentures was compared. The results showed that: 7 days after wearing complete dentures, the mucosal blood flow and blood cell velocity of maxillary anterior alveolar ridge crest decreased significantly (P < 0.05), those of labial region of maxillary anterior alveolar ridge increased significantly (P < 0.05), 14 days after wearing complete dentures, the mucosal blood flow and blood cell velocity almost recovered the levels before wearing the dentures. The results can be relative to adjustment the occlusion in the early period of wearing the complete dentures and not wearing the complete dentures at night.
