Study on Development of Transparent Matrix System and Method to Use in vivo

本实验的目的是研制一种适用于光固化和化学固化复合树脂修复的通用基质体系，并建立一种使用通用基质体系修复复合树脂的新方法。综上所述，得到以下结果：1。结果表明，新研制的透明基质体系是一种可见光固化型复合树脂，可用于可见光固化和化学固化复合树脂的修复。可见光固化复合树脂修复时，建议在厚度1.0mm、40sec的情况下使用基质树脂。3.辐照时间。要注意基质的厚度和可见光的照射时间。复合树脂的硬化性能随基体厚度、体积和辐照时间的减小而减小。从对比研究结果来看，复合树脂修复材料的修复效果是更好的。证实基质系统修复牙合面1类空腔的效果较好。使用基质系统后，牙齿的良好解剖结构得到了很好的恢复。制备基质的方法有体内直接法（direct method）和体外间接石模型法（indirect method）两种。直接法适用于1-2个复合修复体，间接法适用于3个及以上复合修复体。如果没有破坏牙齿物质，可以立即在待修复的表面制作基质，但如果已经发生破坏，则应在制备基质之前使用镶嵌蜡修复牙齿表面。基质材料可单独使用，也可与透明宫颈基质<@D1(] SY.encircledR配合使用。[)@>D1和条形冠。在以下临床病例中发现了这些药物的疗效：宫颈糜烂在“5”，坑和裂隙在“6”，近端表面在“54”，金属嵌体继发龋在“7”。通用矩阵系统被制造成k -矩阵系统<@D1(] SY.encircledR。[)@>D1并被投放市场。少

The purpose of this experiment is to develop a universal matrix system for the restoration of both visible light cured and chemical cured composite resin and to establish a new restorative method using the universal matrix system.To summarize, the following results were obtained :1. It was suggested that the newly developed transparent matrix system, containing matrix paste, is a kind of visible cured type composite resin, and can be used in restoration using both visible light cured and chemical cured composite resin.2. In the case of visible light cured composite resin restoration, it was recommended to use matrix resin in condition of 1.0mm in thickness and 40sec. of irradiation time.3. Careful attention should be paid to the thickness of the matrix and irradiation time of visible light. The hardening property of the composite resin has a tendency to decrease with the matrix thickness volume and the lower ranges of irradiation time.4. From the results of comparative study on the for … More ms of the composite resin restoration. it was confirmed that the effect of the matrix system was superior in the restoration of Class 1 Cavity on the occlusal surface. The fine anatomical structure of the tooth recovered well by the usage of the matrix system.5. There are two methods for matrix fabrication such as the direct method in vivo (direct method) and indirect method using a stone model in vitro (indirect method).6. The direct is suitable for use in 1-2 composite restorations and the indirect method in 3 and above composite restorations.7. In case there is no destruction of the tooth substance, matrix can be made immediately on the surface to be restored, but if destruction has occurred, the tooth surface should be repaired using inlay wax prior to matrix preparation.8. Matrix material can be used alone, also it can be used together with Transparent Cervical Matrix<@D1(] SY.encircledR.[)@>D1 and strip crown form.9. Efficacy of the matices were found in the following clinical cases : Cervical erosion at 「5, pit and fissure Class 1 caries at 6」, proximal surfaces Class 2 caries at 54」 and secondary caries of metal inlay at 7」, respectively.10. The universal matrix system was manufactured into K-Matrix System<@D1(] SY.encircledR.[)@>D1 and was put on the market. Less
