玻璃离子粘固剂已于1983年12月研制成功,并通过鉴定。兹将我科1984年1月以来临床应用情况报告如下。应用范围及操作方法 1.牙体修复:对于牙颈部楔状缺损病例我们采用先以固钻将楔状缺损的表面轻轻磨去一层,暴露新鲜的牙釉质或牙本质,不再作洞型制备,只将表面污物去净,隔离唾液,用75％酒精消毒(不能采用油剂物消毒),吹干,即用本品作修复。对于Ⅱ类及Ⅲ类洞我们只去净余龋,即行充填。调和时,粉:液为2:1,以增加稠度硬度和抗压强度,在
Glass ionomer cement was successfully developed in December 1983 and passed the appraisal. The clinical application of our department since January 1984 will be as follows. Application and methods of operation 1. Tooth restoration: For the wedge-shaped defect of the cervical spine, we first ground the surface of the wedge-shaped defect with a solid drill to expose the fresh enamel or dentin and no longer make holes Preparation, only to the surface of the net dirt, saliva isolation, disinfection with 75% alcohol (can not be sterilized oil agent), dry, that is, to repair this product. For Class II and Class III we only go to net residual caries, that line filling. When reconciled, powder: liquid is 2: 1, in order to increase the consistency hardness and compressive strength, at
