文书代写：牙体修复的树脂基复合材料替代
可见，玻璃离子具有最高的年失败率，因为他们是玻璃硅酸盐，他们没有太多的可持续性。聚酸复合酸基本上是聚合物，具有膨胀热性能，在某些情况下不适合用于牙体修复。选择替代方案是基于最低失败率和牙齿修复所需的性能。树脂基复合材料最适合这种情况，我们将在本报告中讨论它。
材料科学的转变为选择那些对人类危害最小的材料提供了思路。材料科学的学科已经评估了一种叫做纳米技术的新维度，它将允许在纳米级别(即10-9)制造不同的仪器。为了保证牙科仪器的优良性能，将其发展到纳米级是实现这一目标的重要原因之一。t是通过在基板上涂上纳米涂层来改变其性能。纳米技术为在钛基体上合成骨羟基磷灰石“HAp”打开了大门。
制备纳米材料的方法有等离子喷涂法、化学气相沉积法、物理气相沉积法、溶胶-凝胶法等。每种技术都解释了一些特定的属性，这些属性对于任何目的都是必需的。另一种重要的牙齿修复方法是树脂涂层。这是通过阻塞未覆盖的牙本质来实现的，牙本质是一种由牙釉质覆盖在牙冠上的坚硬成分。通过固定牙本质键合结构而产生图案之前，在侧表面刚好提供树脂涂层。树脂涂层有助于增加牙齿和应用树脂之间的粘结强度。所述薄被膜材料用于在所形成的牙本质上形成块状被膜层。薄膜起着至关重要的作用，以保护牙本质形成任何种类的生物，物理或任何化学刺激。此外，薄膜层能够防止任何形式的泄漏，而恢复冠。请记住，薄膜的应用只适用于腔体的局部区域。

It is seen that glass ionomer has the highest annual rate of failure, as they are glass silicates, they don’t have much sustainability. Poly acid composite acids are basically polymers and they have swelling thermal property, which is undesirable to use in dental restoration in some conditions. The selection of the alternative is based on minimum failure rate and the required properties for dental restoration. The resin based composite is best suited in this case, and we will going to discuss it in this report.
The shift in material science has projected the way of thinking towards the selection of those materials that would allow the least harm to the people. The discipline of material science has evaluated a new dimension called nanotechnology which would allow the making of different instruments at Nano level scale i.e. 10-9. One of the important reasons ofadvancing down to Nano scale is to ensure desirable properties of dentistry instruments.t is done by Nano coating on the substrate to alter the properties. Nano technology has opened the gates for the production of synthetic bone hydroxyl apatite “HAp” on Titanium substrate.
There are various fabrication technique available fabricate Nanomaterials such as plasma spraying, chemical vapour deposition, physical vapour deposition, sol-gel, etc. Each technique accounts for some specific properties that are required for any purpose. The other important method of dental restoration is resin coating. This is done by blocking the uncovered dentin which is a hard constituent shielded by enamel over the crown. The resin coat is provided on the side surface just after before producing a pattern by fixing the dentin bond structure. Resin coating helps to increase the strength of bond between the tooth and the applied resin. The material of thin coat is used to form a block filmed layer right on the formed dentin. Thin film plays the vital role to guard the dentin to form any kind of biological, physical or any chemical irritation. In addition to this, thin film layer is able to prevent any sort of leakage while restoring the crown. Keep in mind that the application of thin film is only applied to a localized area of cavity.
