概括
对NHS来说,牙合金修复在长期内比复合材料填充更具成本效益和耐用性. 如果没有显著改变,逐步淘汰合金,可能会对牙存活,成本和获得护理产生负面影响.
科学领域:
- 牙科材料科学 牙科材料科学
- 卫生经济学 卫生经济学
- 公共卫生政策 公共卫生政策
背景情况:
- 牙合金的使用被要求逐步减少,在英国进行了2030年逐步淘汰的可行性研究.
- 在英格兰NHS护理中,合金仍然占主导地位,用于后部修复,但访问是有限的.
- 了解合金与复合材料修复的长期经济和临床影响至关重要.
研究的目的:
- 量化合金与复合材料直接后部修复的相对长期成本和后果.
- 为了比较英格兰国家卫生服务 (NHS) 环境中的成年永久牙的结果.
- 为政策决策提供有关合物逐步淘汰可行性的信息.
主要方法:
- 基于文献审查,使用TreeAge Pro开发了一个微模拟模型.
- 该模型模拟了1万名18岁的NHS患者一生的恢复失败和重新干预.
- 成本和结果的折扣率为3.5%,采用了扩展的医疗部门和社会视角,并进行了敏感性分析.
主要成果:
- 合金修复的成本较低 (患者70英,资助者34英),并且比常规和散装复合材料更耐用 (4年,12年无折扣).
- 合金导致更少的访问 (1),更短的治疗时间 (43分钟) 和更低的实验室成本 (£8).
- 直接恢复不再可能的时间对于合金来说是显着更长的 (6年,17年没有折扣).
结论:
- 该模型显示出良好的有效性,预测牙存活率与NHS索赔数据保持一致.
- 在英国逐步淘汰合金,如果没有实质性的临床医师升级和医疗服务变化,可能会增加终身成本,并对牙恢复和牙存活产生负面影响.
- 这种逐步淘汰可能会降低社会生产力,并加剧现有的护理和社会经济不平等的机会.

Bonding in Metals
Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.
Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Modeling of Diode Forward Characteristics
Understanding the behavior of diodes when forward-biased is a fundamental aspect of electronic circuit design and analysis. This analysis primarily utilizes two models: the exponential diode model and the constant-voltage-drop model. The exponential model comes into play when the source voltage exceeds 0.5 volts, pushing the diode current to rise exponentially above the saturation current. This relationship is graphically depicted in the current-voltage (I-V) curve, illustrating the diode's...
