概括
自蚀刻树脂水泥在将间接美学修复粘合到牙时,与自粘合水泥相比,具有更高的剪接强度. 功能性单体10-Methacryloyloxydecyl二酸盐 (10-MDP) 显著增强了粘合力,而自粘合水泥则显示出较弱的牙键.
科学领域:
- 牙科材料科学
- 粘合性牙科
- 恢复性牙科
背景情况:
- 间接的美学修复需要可靠的牙凝固才能长期成功.

- 自雕刻和自粘树脂水泥提供不同的应用方案和潜在的粘附机制.
研究的目的:
- 为了比较与牙结合的各种间接美观修复材料的自蚀和自粘树脂水泥的剪接强度.
- 在使用这些水泥类型时评估不同修复材料对结合强度的影响.
- 确定与每个水泥类型和修复材料组合相关的断裂模式.
主要方法:
- 80个人的牙被准备成牙样本.
- 使用四种修复材料 (二,,PMMA,混合物) 来制造块.
- 使用自蚀刻 (Panavia V5) 或自粘合 (i-CEM) 树脂水泥将块结到牙上 (每组n=10).
- 测试了剪接强度,并通过光显微镜和SEM分析了断裂模式.
主要成果:
- 自蚀刻水泥 (Panavia V5) 总是比自粘水泥 (i-CEM) 具有更高的剪接强度.
- 在自粘水泥中,Cerasmart 270显示出最强的粘合强度.
- 最初的LiSi块表现出使用自蚀刻水泥的最高结合强度,其次是Katana Zr Noritake,Crowntec NextDent和Cerasmart 270.

01:12Bonding and Strength of Aggregate
259
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...

01:20Strength of Cement
214
Strength tests for cement are not performed directly on neat cement paste due to difficulty in obtaining consistent, reliable specimens. Instead, cement is typically tested in the form of cement-sand mortar.
For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in...

02:40Chemical Bonds
18.1K
Atoms participate in a chemical bond formation to acquire a completed valence-shell electron configuration similar to that of the noble gas nearest to it in atomic number. Ionic, covalent, and metallic bonds are some of the important types of chemical bonds. Bond energy and bond length determine the strength of a chemical bond.
Types of Chemical Bonds
An ionic bond is formed due to electrostatic attraction between cations and anions. Often, the ions are formed by the transfer of electrons...

02:49Bond Energies and Bond Lengths
25.8K
Stable molecules exist because covalent bonds hold the atoms together. The strength of a covalent bond is measured by the energy required to break it, that is, the energy necessary to separate the bonded atoms. Separating any pair of bonded atoms requires energy — the stronger a bond, the greater the energy required to break it.

01:17Mortar Properties
187
Mortar properties encompass a range of characteristics crucial for construction and masonry work, including workability, water retention, bond strength, durability, compressive strength, volume change, and appearance. Workability refers to mortar's ability to be easily applied and manipulated without sagging or falling off surfaces, which is important for efficient masonry unit placement and alignment. Water retention is essential to prevent the mortar from losing moisture too quickly to...
