Summary
Choosing dental cements involves considering substrate, restoration type, and patient needs. This guide reviews traditional glass ionomer (GI) and resin-modified glass ionomer (RMGI) cements, plus resin cements for various restorations, aiding clinical decisions.
Area of Science:
- Dental Materials Science
- Restorative Dentistry
- Biomaterials
Background:
- Selecting dental cements for crowns and bridges requires careful consideration of substrate compatibility, restoration type, and patient-specific factors.
- Certain substrates necessitate specific pre-treatment protocols before cementation to ensure optimal bond strength and longevity.
- Traditional cements like glass ionomer (GI) and resin-modified glass ionomer (RMGI) are commonly used for metal and metal-ceramic restorations.
Purpose of the Study:
- To review the properties, advantages, disadvantages, indications, and contraindications of commonly used dental cements.
- To provide guidance on the appropriate use of GI, RMGI, and resin cements for various restorative materials including metal, ceramic, and composite.
- To discuss surface treatment guidelines for silica- and zirconia-based restorations when employing resin cements.
Main Methods:
- Literature review of traditional crown and bridge cements (GI and RMGI) and resin cements.
- Analysis of cement properties, clinical applications, and contraindications.
- Synthesis of recommended uses and surface treatment protocols for different restorative substrates.
Main Results:
- GI and RMGI cements are suitable for metal and metal-ceramic restorations, with specific indications and contraindications.
- Resin cements are indicated for all-ceramic restorations, offering enhanced aesthetics and bonding.
- Surface treatments for silica- and zirconia-based restorations are crucial for resin cement efficacy.
Conclusions:
- Appropriate cement selection is vital for successful crown and bridge restorations, balancing material properties with clinical needs.
- Understanding the nuances of GI, RMGI, and resin cements, along with substrate preparation, optimizes treatment outcomes.
- This review provides a framework for clinicians to make informed decisions regarding dental cementation strategies.

01:22Types of Cement II
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 resistance.
01:12Bonding 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...
01:17Mortar Properties
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 the...
02:36Crown Ethers
Crown ethers are cyclic polyethers that contain multiple oxygen atoms, usually arranged in a regular pattern. The first crown ether was synthesized by Charles Pederson while working at DuPont in 1967. For this work, Pedersen was co-awarded the 1987 Nobel Prize in Chemistry. Crown ethers are named using the formula x-crown-y, where x is the total number of atoms in the ring and y is the number of ether oxygen atoms. The term 'crown' refers to the crown-like shape that these ether molecules take.
01:25Accelerated Curing of Concrete
Accelerating concrete curing is achieved by applying heat and additional moisture. This process accelerates the hydration of the cement, resulting in an earlier strength gain in the concrete. Steam curing is a method wherein the concrete products are either transported through a chamber on a conveyor belt or encased in plastic, allowing steam at atmospheric pressure to circulate freely around them. This process begins with a phase of moist curing that typically lasts between 3 to 5 hours, after...
01:29Mortar
Mortar, a mixture of Portland cement, hydrated lime, sand, and water, is a crucial binding material in construction. Its primary function is to join masonry units together, filling gaps and ensuring a uniform distribution of weight across the structure. This helps in preventing potential weaknesses. Mortar also serves as a protective barrier against environmental elements such as water and wind, thereby safeguarding the interior of the structure. It also compensates for surface irregularities...
