Summary
Achieving successful porcelain laminate veneers (PLVs) requires meticulous adhesive cementation. Precise techniques and understanding materials are crucial for veneer longevity and esthetics.
Area of Science:
- Restorative Dentistry
- Dental Materials Science
Background:
- Porcelain laminate veneers (PLVs) are esthetic dental restorations.
- Clinical success depends on various factors, notably adhesive cementation.
- Suboptimal cementation can lead to failure, compromising veneer integrity and esthetics.
Purpose of the Study:
- To identify clinical parameters influencing successful PLV cementation.
- To focus on adhesive strength, integrity, and esthetics of PLVs.
- To review scientific evidence on optimal cementation protocols.
Main Methods:
- Conducted a literature search using MEDLINE and hand searches.
- Included English articles published between 1995 and 2023.
- Focused on studies detailing clinical parameters and outcomes of PLV cementation.
Main Results:
- Precise cementation technique is vital for PLV success and longevity.
- Key steps include field isolation, material selection, manipulation, seating, polymerization, and excess cement removal.
- Pre-cementation steps like treatment planning and preparation significantly impact cementation quality.
Conclusions:
- Successful adhesively luted PLVs depend on understanding materials and implementing clinical protocols.
- Comprehensive case selection, planning, and execution are critical for predictable short- and long-term outcomes.
- Adherence to meticulous protocols throughout the process ensures optimal PLV performance.

Porosity in Cement Paste
173
The porosity of concrete is a measure of the void spaces within its structure. These spaces impact its strength and durability significantly. When water and cement interact, a chemical reaction called hydration creates a semi-solid paste. This paste includes combined water, making up approximately 23% of the cement's dry mass, and gel water, which fills minuscule voids known as gel pores, accounting for about 28% of the cement gel volume.

Veneer
108
Veneer refers to a thin sheet of wood, typically produced to a thickness of about one-eighth of an inch or less. This material is crafted through various methods, the most common being rotary cutting. In this process, a log is mounted into a large lathe and spun against a knife edge, peeling off a continuous strip of wood as the knife penetrates deeper into the rotating log, creating a rotary-cut veneer.
Other veneering techniques include plain-slicing, quarter-slicing, and rift-slicing. These...

Soundness of Cement
200
The soundness of cement refers to the ability of cement paste to retain its volume after setting. Unsound cement can lead to expansion and structural damage due to the presence of free lime, magnesia, and calcium sulfate. Free lime hydrates very slowly, expanding and causing unsoundness, which is difficult to detect because it intercrystallizes with other compounds. Magnesia also reacts with water, forming crystals that can disrupt the cement's structure. Calcium sulfate can create...

Mortar Properties
149
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...

Setting Time of Cement
201
The setting time of cement refers to the process of cement paste transitioning from a plastic state to a solid state. This process is crucial in construction as it dictates the timeframe for concrete placement, compaction, and finishing. The onset of this solidification is termed the initial set, indicating when the paste becomes unworkable. The final set is when the paste has solidified completely, and further handling or manipulation can no longer affect its shape. The cement strength is...

Types of Cement II
131
Portland blast-furnace cement is made by blending Portland cement clinker with granulated blast-furnace slag, which accounts for 25 to 65 percent of the cement's weight. Despite its similarities to ordinary Portland (Type I) cement in terms of fineness and setting times, its early strength is lower, though it achieves comparable strength later on. It's particularly suited for mass concrete structures and marine environments due to its lower heat of hydration and superior sulfate...
