概括

重复燃烧并没有显著影响基芯和热压离之间的剪接强度 (SBS). 这表明多个烧火周期可能不会损害间接陶修复的结合完整性.

科学领域:

牙科材料科学牙科材料科学
生物材料工程生物材料工程
牙修复牙修复牙修复牙修复牙修复

背景情况:

间接的陶修复经常需要多次烧烤以进行阴影匹配和临床调整.
之前的研究集中在多次发烧后的石涂层假肢的机械性能上.
重复燃烧对芯和热压二酸盐层陶之间的结合强度的影响仍然在很大程度上未被探索.

研究的目的:

为了评估和比较重复燃烧周期对平面接口切割键强度 (SBS) 在芯和热压二氧化之间的影响.
为了确定是否增加燃烧周期会影响这些间接陶修复材料的粘合质量.

主要方法:

准备了40个石框架样本,并分为四组:控制,1,2和3个燃烧周期.
使用施密茨-舒尔迈耶测试来评估平面接口的剪接强度 (SBS).
使用通用测试机器测量SBS,并分析故障模式.

主要成果:

所有实验组的平均SBS值均可比较,对照组的SBS值略高.
差异分析 (ANCOVA) 显示,两组之间的平均SBS没有统计学上显著的差异.
确定最大负载是影响SBS的重要因素,通过回归和相关性分析得到证实.

结论:

将燃烧周期的数量从1增加到3并没有显示出对石和热压二酸盐之间的剪接强度有显著影响.
该研究的假设是,重复发射会对SBS产生负面影响,这一假设没有得到支持.
主要的粘合剂故障模式不会随着燃烧周期的增加而改变.

Trends in Lattice Energy: Ion Size and Charge

Trends in Lattice Energy: Ion Size and Charge

An ionic compound is stable because of the electrostatic attraction between its positive and negative ions. The lattice energy of a compound is a measure of the strength of this attraction. The lattice energy (ΔHlattice) of an ionic compound is defined as the energy required to separate one mole of the solid into its component gaseous ions. For the ionic solid sodium chloride, the lattice energy is the enthalpy change of the process:

Bonding and Strength of Aggregate

Bonding and Strength of Aggregate

The bond between aggregate particles and the cement matrix is significantly influenced by the shape and surface texture of the aggregates. High-strength concretes benefit from a rougher texture, which leads to stronger bonding due to greater adhesion. Angular aggregates with larger surface areas also enhance this bond. The bonding quality, however, is complex to assess as no universally accepted test exists. Good bonding is indicated when a crushed concrete specimen shows some aggregate...
