【摘要】 作者对25个 CW—PA 烤瓷 Ni-Cr-Nb 合金制作的底层冠试件,通过测量粘固前、后的边缘浮出量,探讨粘固剂对底层冠就位的影响。结果发现,粘固后的边缘浮出量比粘固前明显增加 (P<0.01)。建议为获得冠的完全就位,达到良好的边缘适合性,采用冠的组织面缓冲,以提供粘固剂的间隙是必要的。更多还原

【Abstract】 The influence of cement on seating of PFM coping had probed by measurement ofmarginal opening of CW-PA Ni-Cr-Nb alloy coping samples before and after cement-ation.The result showed that after cementation,the marginal opening increased obvio-usly than before(P<0.01).Therefore,buffering the inner surface of coping toprovide a space for cement is necessary to obtain a complete seated coping with goodmarginal adaptibility.更多还原
