项目摘要

Surface treatment by the use of silver-mirrorreaction : New surface treatment method for promoting the bonding of direct metal restorative materials and tooth substance without cementing agent was applied. The silver-mirror reaction of ammoniacal silver nitrate solution by the use of rducing power of aldehyde group in formaldehyde enabled on the tooth surface at the room temperature and short time. As the resuts of metallic silver, which phates out on the tooth surface, reacts with mercury and/or gallium as a liquid metals in the direct methal restorative materials, direct methal restorative materials were fixed tightly without cementing agent on the tooth substance. Furthermore, there is no construction gap at the interface of direct metal restorative materials and tooth substance through metallic silver on the tooth surface.Improvement of amalgam-bonding method : The compressive shear bond strength (CSBS) of amalgam (Dispersalloy : DA) and gallium alloy (Gallium alloy GF : Ga-GF) wit … More h commercial bonding agents and resin cements to the bovine tooth substance were determined. Especially, it was examined the method of the dentin surface treatment with acid as a hydroxyapatite solubilizer and sodium hypochlorite as a collagen solubilizer. Changing in state from the collagen rich to the hydroxyapatite rich on the dentinal surface took remarkable improvement in adhesion. The CSBS of DA and Ga-GF with Panavia EX (+ Clearfil new bond) to the dentin was 9.7Mpa and 30Mpa, respectively. The relaxation on setting expansion of Ga-GF of the internal stress on the polymerization shrinkage of the resin cement at the interface between resin cement and tooth substance was main reason that could be explained the advantage to Ga-GF to DA in adhesion.New adhesive monomer : The primer containing N,N'-dimethacryloylcystine, as a multifunctional monomer, with disulfide and carboxyl groups was utilized for surface treatment of tooth hard tissues (enamel and dentin) and dental metal alloys improve the adhesion of bonding agents and resin cements. The primer effectively enhanced the bond strength of Superbond (TBBO iniciator) to precious, semi-precious and nonprecious metal alloys. However, the primer ineffectively enhanced the bond strength to Panavia-21 (ternary iniciator with BPO-amine) to dental metal alloys. Less

通过使用银色锻炼的表面处理：采用了新的表面处理方法，用于促进直接金属恢复材料和牙齿物质的粘结而无需胶结剂。通过在室温和短时间内在牙齿表面启用了甲醛中醛基的rd型功率，硝酸银溶液的银色晶体反应。当其余的金属银在牙齿表面上呈现出来，与汞和/或胆汁作为直接金属修复材料中的液体金属反应，直接金属修复材料被紧密固定，而无需在牙齿底物上胶结剂。 Furthermore, there is no construction gap at the interface of direct metal restorative materials and tooth substrate through metallic silver on the tooth surface.Improvement of amalgam-bonding method: The compressive shear bond strength (CSBS) of amalgam (Dispersalloy : DA) and gallium alloy (GF: Ga-GF) wit … More h commercial bonding agents and resin cements to the bovine tooth substrate were determined.尤其是，检查了用酸作为羟基溶解剂和次氯酸钠作为胶原蛋白溶液剂的牙齿表面处理方法。从富含胶原蛋白到牙齿表面的羟磷灰石的状态变化取得了显着改善。 DA和GA-GF的CSB与Panavia ex（+ Clearfil New Bond）的CSB分别为9.7MPa和30MPa。 The relaxation on setting expansion of Ga-GF of the internal stress on the polymerization shrinkage of the resin cement at the interface between resin cement and tooth substance was main reason that could be explained the advantage to Ga-GF to DA in adhesive.New adhesive month : The primer containing N,N'-dimethacryloylcystine, as a multifunctional month, with disulfide and carboxyl groups were utilized for surface treatment of太硬组织（搪瓷和牙本质）和牙科合金改善了粘合剂和树脂水泥的粘合剂。底漆有效地增强了Superbond（TBBO Inicator）的键强度，对珍贵，半纯净和非纯属金属合金。但是，底漆无效地增强了对牙科金属合金的Panavia-21（带有BPO-胺）的键强度。较少的
