激光拉曼光谱是一种对生物体结构毫无损伤的分子结构分析手段,本实验分别对碳纤维桩与玻璃离子、磷酸锌和树脂粘接剂的粘接界面采用激光拉曼光谱信号检测,以便探讨不同粘接材料与粘接底物的粘接强度产生差异的原因。由检测结果可见显微激光拉曼光谱仪可为生物分子结构信息提供一种新的方法,可用于检测口腔不同粘接剂-桩粘接界面的微观结构,为临床上桩和粘接材料的选择提供理论依据。
Laser Raman spectroscopy is a kind of molecular structure analysis method which has no damage to the biological structure. In this experiment, laser Raman spectroscopy signal detection is performed on the bonding interface between the carbon fiber post and the glass ion, the zinc phosphate and the resin adhesive so that To explore the reasons for the difference between the adhesive strength of different adhesive materials and adhesive substrates. From the test results, it can be seen that the Raman microscope provides a new method for biomolecular structure information, which can be used to detect the microstructure of different adhesive-pile bonding interface in the oral cavity. It is the choice of clinical pile and adhesive material Provide a theoretical basis.
