To investigate the influence which the difference of the structure of the limit bonding phase boundary and moreover the ivory quality exerts on the one of the bonding strength as far as it is possible. It set up and it developed micro bonding gluing strength measurement equipment by the examination.To analyze relate-ability with the crystal structure, as for the area of the gluing part, it thought of about 2mm^2 and it bought an improvement-type examination machine for its purpose and attachment which agreed with the purpose, too, was complete.Also, it experimented at the area, it put on shear bonding strength which was adopted in the past and about 1.5-twice of gluing strength were shown at most of the material compared with the result of the examination. Bond strength evaluation will need to performed using an interfacial fracture mechanics approach, which is more complicated compared with the simple bond strength test.In addition to that the equipment of the diffraction of the X ray … More of the micro subsection and the super film to be using for this experiment can make the crystal structure of the sample surface clear not, in the micro subsection (the 1- mum diameter), the crystal structure from the IOA thickness can be known. It examines a way of measuring sample, a measurement condition more in the future and it plans to examine the cause of the difference with gluing strength by the solid difference and relation with normal teeth. Most became lmm2 to exclude as far as the bonding area which is reported in recent years can make the influence of the flaw of the gluing phase boundary. It gets the result that this study person, too, adopted it, not to have thought only that he is the phenomenon of the flaw but for gluing strength, too, to have been increased with the area.Nano indenter hardness values at the point 10mum away from the interface in the direction of the dentin differed between system. This appeared to be influenced by the presence of the decalcified dentin not impregnated by resin, and by differences in both the chemistry of the hybrid layer and the composition of bonding resin. In the hybrid layer, no impression was found by SEM, although the hardness in the bonding interface was significantly different. It plans to pursue phase boundary observation having to do with a form, the crystal structure, the mechanical nature of it more. Less

为了研究极限键相边界结构的差异以及象牙质量对粘结强度之一的影响。它建立并通过检查开发了微粘结强度测量设备。与晶体结构分析性关系，如胶水的区域，它认为大约2mm^2，并购买了一台改进的型检查机，以实现其目的和依恋，与该目的同意，它是完整的。与检查结果相比，大多数材料显示胶强度。 Bond strength evaluation will need to perform using an interfacial fracture mechanicals approach, which is more complicated compared with the simple bond strength test.In addition to that the equipment of the Difference of the X ray … More of the micro subsection and the super film to be using for this experiment can make the crystal structure of the sample surface clear not, in the micro subsection (the 1- mum diameter), the crystal structure from the IOA thickness can be known.它检查了一种测量样品的方法，未来的测量条件更多，并计划通过固体差异和与正常牙齿的关系来检查与侧翼强度差异的原因。大多数变成了LMM2，以排除近年来报道的粘结区域可能会影响胶相边界缺陷的影响。结果是，这项研究人员也采用了它，而不是只认为他是缺陷的现象，而是因为胶水强度也随着面积而增加。纳米诺缩进的硬度值在距离牙本质之间的方向上的界面上的10mum sugnter硬度值在系统之间不同。这似乎受树脂未浸渍的脱钙化牙本的存在，以及杂交层的化学和键合树脂的组成的差异。在混合层中，尽管粘结界面的硬度显着差异，但没有发现SEM的印象。它计划追求相边界的观察与形式，晶体结构，其机械性质有关。较少的
