这项工作的目的是提出一种成分的分析，并为牙科医生提供一个基础，可以为选择一种或另一种来满足他们的治疗要求提供标准。咀嚼是一个动态的过程，牙齿是咀嚼的重要组成部分。修复丢失的牙齿结构对牙医和测试修复材料的科学家来说都是一个挑战。最常用的修复材料之一是复合树脂。复合树脂的力学性能主要取决于其填充物的含量。长期以来，牙科复合材料一直使用二氧化硅、石英和玻璃作为填料。氧化锆是最新加入的填充物。由于特殊的原子排列，氧化锆是超硬的。咀嚼是一种动态的情况，在这种情况下，许多力都在向所有可能的方向作用，最重要的是压缩力。我们希望研究氧化锆作为填充物对牙科复合材料力学性能的贡献。我们的目标是优化基于Bis-GMA和TEGDMA的牙科复合材料的氧化锆纳米团簇的压缩强度。本论文的目的是评价氧化锆作为填料在牙科复合材料抗压强度中的重要作用。当代牙科复合材料正在单独或组合使用一种或两种填充物。尝试使用氧化锆、玻璃和二氧化硅砾岩。得到了混杂填料的最佳组成和最佳抗压强度。
The aim of this work is to present an analysis of the composites and furnish dentists with a basis that can provide criteria for choosing one or another to suit their therapeutic requirements. Mastication is a dynamic process and tooth is an important component of it. Restoration of lost tooth structure is a challenge to the dentist as well as scientists testing the restorative materials. One of the most commonly used restorative materials is composite resin. The mechanical properties of composite resins are mainly due to its filler content. Dental composites are using silica, quartz and glass as filler for long time. Zirconia is the latest addition as filler. Zirconia is super hard because of the peculiar arrangements of atoms. Mastication is a dynamic situation in which many forces are acting in all possible direction, the most important being the compressive force. We wish to study the contribution of Zirconia as filler in the mechanical properties of the dental composite. Our aim is to optimise the compressive strength in Zirconia nanoclusters of the Bis-GMA & TEGDMA based dental composites. The aim of this paper is to evaluate the important role of Zirconia as filler in the Compressive strength of Dental Composite. Contemporary dental composites are using either one or two fillers individually or in combination. Attempt is made to use Zirconia, glass and silica conglomerate. The optimum composition of hybrid fillers and the optimum compressive strength is obtained.
