The Glass Ionomer Cement Reinforced with Silver - Premise in Choosing the Teeth Proposed for Orthodontic Purpose Extraction

Abstract

The glass ionomer cements present very good bio compatibility especially due to the presence of Fluor in their composition. The reactivity from the dental pulp to the ionomer cements is also favorable, even in the case of the profound cavities. The metallic ionomer cements are obturation materials that tend to replace the amalgams and were created by adding of metallic alloys to the glass powder for the purpose of improving the mechanic properties. The resistance to abrasion of the glass ionomer cements reinforced with Ag is increased compared to the ionomer cements, being close to that of the composite resins with micro filling, but inferior to the amalgams or composites for the posterior area. All these properties of the metallic glass ionomers recommend their utilization in accomplishing the definitive obturations of the permanent teeth from the lateral area, where the physiognomic aspect is not on the first place and where it is necessary a material with fast grip. The physical-chemical qualities and the bio compatibility of the glass ionomers reinforced with particles of silver was our premise in their utilization for the obturation of the molars of six years in children.

Synthesis and Comparative Characterization of Different Microparticles used as Biomaterials in Dentistry

“…They can have a significant allergic, toxic or carcinogenic effect. The physico-chemical qualities and biocompatibility of dental materials such as composites, are necessary conditions in their use in the oral cavity [24][25][26].…”

Fluoride Release and Uptake Capability of Glass-ionomer Cements and Compomers Used as Dental Restorative Materials

“…They have a good adhesion to tooth structures, their pulp damaging effect is minimal and thanks to their fluoride releasing capability, they play a role in strengthening the tooth against secondar y caries, thus presenting cariostatic and antimicrobial action [1,2,10,[11][12][13][14][15]. GICs are also used in young patients' permanent posterior teeth, where fast adhesion is required [16]. They have the advantage of being less sensitive to moisture than resin-based materials.…”
