本文对三种不同类型粘固剂与修复体的表面粘结力和固位力进行了测试比较。测定结果:磷酸锌粘固剂对牙和牙用合金的粘结作用均较差,固位作用也较低;多碳氧粘固剂对牙表面有较明显的粘结力,但对牙用合金无粘结作用、固位力也较差;HY多碳氧粘固剂含有防龋成份,如锌氟、锶氟、鞣酸等,并对牙表面和牙用合金均有较显著的粘结作用和较强的固位作用。作者所采用的研究方法如下。固位力的测试:用粘固剂把牙用合金铸件与已预备的牙釉质、牙本质表面粘结在一起进行粘固剪应力的测定。将牛的切牙,用磨牙把接近釉牙本质界处的牙釉质或牙本质磨成扁平表面后,埋入人造石中,其预备的牙
In this paper, the surface adhesion and retention of three different types of cement and prosthesis were tested and compared. The results showed that zinc phosphate cement had poor adhesion to dental and dental alloys and had a lower retention effect. More carbon-oxygen cement had more obvious adhesion to the tooth surface, The bonding strength of the alloy is also poor. HY multi-carbon oxygen cement contains anti-caries ingredients such as zinc fluoride, strontium fluoride, tannic acid and so on, and has a significant bonding on the tooth surface and dental alloys Role and strong retention effect. The research methods adopted by the author are as follows. Retention test: The dental alloy castings are cemented together with the prepared enamel and dentin surfaces to determine the shear stress. The bovine incisor, the use of teeth close to the enamel enamel dentin border enamel or dentin ground into a flat surface, embedded in artificial stone, the preparation of teeth
