项目摘要

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

该实验的目的是开发一个通用矩阵系统，以恢复可见光的光固化和化学固化的复合树脂，并使用通用矩阵系统建立一种新的恢复方法。总而言，获得以下结果：1。有人提出，新开发的透明矩阵系统（包含基质糊状物）是一种可见的固化型复合树脂，可用于使用可见光的固化和化学固化的复合树脂进行恢复。2。在可见光的光固化复合树脂恢复的情况下，建议使用厚度为1.0mm和40秒的基质树脂。辐照时间3。应仔细注意矩阵的厚度和可见光的照射时间。复合树脂的硬化特性随着基质厚度体积和辐射时间的较低范围而降低。4。从有关…更多MS的复合树脂恢复的比较研究结果。已经证实，基质系统在咬合表面的1类腔体的恢复中的效果是较高的。牙齿的精细解剖结构通过基质系统的使用很好地恢复了。5。有两种用于基质制造的方法，例如使用石材模型的体外方法（直接方法）和间接方法（间接方法）（间接方法）。6。该直接适用于1-2复合修复体和3及以上复合修复体中的间接方法7。如果没有破坏牙齿物质，则可以立即在表面上恢复矩阵，但是如果发生破坏，则应在矩阵制备之前使用inlay蜡修复牙齿表面8。矩阵材料可以单独使用，也可以与透明的宫颈矩阵<@d1（] sy.encircledr。[）@> d1和带状冠形式一起使用。在以下临床病例中发现了伴侣的功效：宫颈侵蚀在“ 5，凹坑和裂缝1级龋齿时为6”，分别为54英寸的近端2类龋齿和7个金属镶嵌的次级龋齿。10.10。通用矩阵系统是在K-Matrix系统<@d1（] sy.encircledr。[）@> d1中制造的，并被投放到市场上。较少的
