Structure of dental inlays and onlays In dentistry, inlays and onlays are used to fill cavities, [ 1 ] and then cemented in place in the tooth . This is an alternative to a direct restoration , made out of composite, amalgam or glass ionomer , that is built up within the mouth.
Dental compomers are another type of white filling material although their use is not as widespread. [ 15 ] [ 16 ] [ 17 ] Compomers were formed by modifying dental composites with poly-acid in an effort to combine the desirable properties of dental composites, namely their good aesthetics, and glass ionomer cements, namely their ability to ...
This discussion of the dental amalgam controversy outlines the debate over whether dental amalgam (the mercury alloy in dental fillings) should be used. Supporters claim that it is safe, effective and long-lasting, while critics argue that amalgam is unsafe because it may cause mercury poisoning and other toxicity. [1] [2] [3]
Indirect dental composites can be used for: Filling cavities in teeth, as fillings, inlays and/or onlays; Filling gaps (diastemas) between teeth using a shell-like veneer or; Reshaping of teeth; Full or partial crowns on single teeth; Bridges spanning 2-3 teeth; A stronger, tougher and more durable product is expected in principle.
A glass ionomer cement (GIC) is a dental restorative material used in dentistry as a filling material and luting cement, [1] including for orthodontic bracket attachment. [2] Glass-ionomer cements are based on the reaction of silicate glass-powder (calciumaluminofluorosilicate glass [ 3 ] ) and polyacrylic acid , an ionomer .
The same year, the use of dental amalgam was declared to be malpractice by the American Society of Dental Surgeons (ASDS), the only US dental association at the time, who forced all of its members to sign a pledge to abstain from using the mercury fillings. [7] This was the beginning of what is known as the first dental amalgam war. [8]
Compomers absorb water more rapidly than dental composites due to the addition of hydrophilic resin monomers within the matrix (see Composition section above). As such, water equilibrium is reached within days rather than weeks, months or even years in the case of dental composite materials. This property has the advantage of compensating for ...
Dental restorative materials are used to replace tooth structure loss, usually due to dental caries (cavities), but also tooth wear and dental trauma. On other occasions, such materials may be used for cosmetic purposes to alter the appearance of an individual's teeth.
