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.
本研究的目的是确定全口义齿对牙槽黏膜微循环的影响。通过视频显微镜测量了17名无牙颌受试者的牙槽黏膜微循环。比较了义齿佩戴前后牙槽黏膜微循环的变化。结果显示：佩戴全口义齿7天后，上颌前牙槽嵴顶的黏膜血流和血细胞速度显著降低（P<0.05），上颌前牙槽嵴唇侧区域的黏膜血流和血细胞速度显著增加（P<0.05）；佩戴全口义齿14天后，黏膜血流和血细胞速度几乎恢复到佩戴义齿前的水平。这些结果可能与佩戴全口义齿早期的咬合调整以及夜间不佩戴全口义齿有关。
