Fluoride-releasing restorative materials made by the sintering of metal (usually silver) particles to glass ionomer powder. Glass ionomers are fluoride-releasing cements that are not very durable. Sintering of the metal particles is a means of improving those physical properties that will make the glass ionomer cement more durable.
Adhesives used to fix prosthetic devices to bones and to cement bone to bone in difficult fractures. Synthetic resins are commonly used as cements. A mixture of monocalcium phosphate, monohydrate, alpha-tricalcium phosphate, and calcium carbonate with a sodium phosphate solution is also a useful bone paste.
Substances used to bond COMPOSITE RESINS to DENTAL ENAMEL and DENTIN. These bonding or luting agents are used in restorative dentistry, ROOT CANAL THERAPY; PROSTHODONTICS; and ORTHODONTICS.
Dental cements composed either of polymethyl methacrylate or dimethacrylate, produced by mixing an acrylic monomer liquid with acrylic polymers and mineral fillers. The cement is insoluble in water and is thus resistant to fluids in the mouth, but is also irritating to the dental pulp. It is used chiefly as a luting agent for fabricated and temporary restorations. (Jablonski's Dictionary of Dentistry, 1992, p159)
A polymer obtained by reacting polyacrylic acid with a special anion-leachable glass (alumino-silicate). The resulting cement is more durable and tougher than others in that the materials comprising the polymer backbone do not leach out.

Clinical performance of a condensable metal-reinforced glass ionomer cement in primary molars. (1/2)

OBJECTIVE: Aim of the present study was to evaluate the clinical suitability of the condensable metal-reinforced glass ionomer cement Hi-Dense in classes I and II cavities of primary molars. METHODS: Seventeen children received a total of fifty four Hi-Dense fillings (nineteen class I and thirty five class II). The restorations were clinically assessed at baseline, after one and after two years of clinical service according to modified USPHS codes and criteria. The restorations were replicated in each recall and representative samples were qualitatively analysed under a SEM. RESULTS: Over the observation period of two years, five restorations failed due to total retention loss, two fillings needed replacement because of persisting hypersensitivity, one filling was lost because of an unsuccessful endodontic treatment, and four restorations remained intact until natural exfoliation (Two year survival rate: 92% for Class I and 66% for Class II). The SEM analysis of surfaces and marginal areas exhibited an inferior adhesive performance primarily in proximal areas, whereas a negative step formation due to wear was frequently observed in occlusal parts. CONCLUSIONS: The results clearly indicate that the condensable, metal-reinforced GIC Hi-Dense reveals no enhanced performance and lifetime expectancy for class II restorations in primary molars when compared to other non-resin-modified GICs.  (+info)

A review of chemical-approach and ultramorphological studies on the development of fluoride-releasing dental adhesives comprising new pre-reacted glass ionomer (PRG) fillers. (2/2)

This paper reviews our recent studies on fluoride-releasing adhesives and the related studies in this field based on information from original research papers, reviews, and patent literatures. A revolutionary PRG (pre-reacted glass ionomer) filler technology--where fillers were prepared by the acid-base reaction of a fluoroaluminosilicate glass with polyalkenoic acid in water, was newly developed, and a new category as "Giomer" was introduced into the market. On fluoride release capability, SIMS examination revealed in vitro fluoride ion uptake by dentin substrate from the PRG fillers in dental adhesive. On bonding durability, it was found that the improved durability of resin-dentin bonds might be achieved not only via the strengthened dentin due to fluoride ion uptake from the PRG-Ca fillers, but also due to retention of relatively insoluble 4-AETCa formed around remnant apatite crystallites within the hybrid layer in 4-AET-containing self-etching adhesives. On ultramorphological study of the resin-dentin interface, TEM images of the PRG-Ca fillers revealed that the dehydrated hydrogel was barely distinguishable from normal glass fillers, if not for the concurrent presence of remnant, incompletely reacted glass cores. In conclusion, it was expected that uptake of fluoride ions with cariostatic effect from PRG-Ca fillers would endow dentin substrates with the benefit of secondary caries prevention, together with an effective and durable adhesion to dentin.  (+info)

Cermet cements are a type of dental restorative material that is composed of a combination of ceramic and metal particles. "Cermet" is short for "ceramic-metallic." These cements are typically used to bond crowns, bridges, or other types of dental restorations to natural teeth.

The ceramic component of cermet cements provides excellent esthetic properties, as it can be matched to the color of the surrounding teeth. The metal component, on the other hand, provides strength and durability to the cement. Together, these two components create a restoration that is both strong and natural-looking.

Cermet cements are typically made using a powder and liquid mixture that is mixed together and then applied to the dental restoration and tooth surface. Once the cement has hardened, it creates a strong bond between the restoration and the tooth.

Overall, cermet cements are a reliable and effective option for bonding dental restorations to natural teeth. They offer a number of benefits over other types of dental cements, including their strength, durability, and esthetic properties.

Bone cements are medical-grade materials used in orthopedic and trauma surgery to fill gaps between bone surfaces and implants, such as artificial joints or screws. They serve to mechanically stabilize the implant and provide a smooth, load-bearing surface. The two most common types of bone cement are:

1. Polymethylmethacrylate (PMMA) cement: This is a two-component system consisting of powdered PMMA and liquid methyl methacrylate monomer. When mixed together, they form a dough-like consistency that hardens upon exposure to air. PMMA cement has been widely used for decades in joint replacement surgeries, such as hip or knee replacements.
2. Calcium phosphate (CP) cement: This is a two-component system consisting of a powdered CP compound and an aqueous solution. When mixed together, they form a paste that hardens through a chemical reaction at body temperature. CP cement has lower mechanical strength compared to PMMA but demonstrates better biocompatibility, bioactivity, and the ability to resorb over time.

Both types of bone cements have advantages and disadvantages, and their use depends on the specific surgical indication and patient factors.

Dental cements are materials used in dentistry to bond or seal restorative dental materials, such as crowns, fillings, and orthodontic appliances, to natural tooth structures. They can be made from various materials including glass ionomers, resin-modified glass ionomers, zinc oxide eugenol, polycarboxylate, and composite resins. The choice of cement depends on the specific clinical situation and the properties required, such as strength, durability, biocompatibility, and esthetics.

Resin cements are dental materials used to bond or cement restorations, such as crowns, bridges, and orthodontic appliances, to natural teeth or implants. They are called "resin" cements because they are made of a type of synthetic resin material that can be cured or hardened through the use of a chemical reaction or exposure to light.

Resin cements typically consist of three components: a base, a catalyst, and a filler. The base and catalyst are mixed together to create a putty-like consistency, which is then applied to the restoration or tooth surface. Once the cement is in place, it is exposed to light or allowed to chemically cure, which causes it to harden and form a strong bond between the restoration and the tooth.

Resin cements are known for their excellent adhesive properties, as well as their ability to withstand the forces of biting and chewing. They can also be color-matched to natural teeth, making them an aesthetically pleasing option for dental restorations. However, they may not be suitable for all patients or situations, and it is important for dental professionals to carefully consider the specific needs and conditions of each patient when choosing a cement material.

Glass Ionomer Cements (GICs) are a type of dental restorative material that have the ability to chemically bond to tooth structure. They are composed of a mixture of silicate glass powder and an organic acid, such as polyacrylic acid. GICs have several clinical applications in dentistry, including as a filling material for small to moderate sized cavities, as a liner or base under other restorative materials, and as a cement for securing crowns, bridges, and orthodontic appliances.

GICs are known for their biocompatibility, caries inhibition, and adhesion to tooth structure. They also have the ability to release fluoride ions, which can help protect against future decay. However, they are not as strong or wear-resistant as some other dental restorative materials, such as amalgam or composite resin, so they may not be suitable for use in high-load bearing restorations.

GICs can be classified into two main types: conventional and resin-modified. Conventional GICs have a longer setting time and are more prone to moisture sensitivity during placement, while resin-modified GICs contain additional methacrylate monomers that improve their handling properties and shorten their setting time. However, the addition of these monomers may also reduce their fluoride release capacity.

Overall, glass ionomer cements are a valuable dental restorative material due to their unique combination of adhesion, biocompatibility, and caries inhibition properties.
