Versatility: Composite fillings can be used to repair chipped, broken or worn teeth [18] which would not be repairable using amalgam fillings. Repairability: In many cases of minor damage to a composite filling, the damage can be easily repaired by adding additional composite. An amalgam filling might require complete replacement.
Fillings are recommended for small to medium-sized restorations. Inlays and onlays are more expensive indirect restoration alternative to direct fillings. They are supposed to be more durable, but long-term studies did not always detect a significantly lower failure rate of ceramic [21] or composite [22] inlays compared to composite direct ...
GIC fillings are a mixture of glass and an organic acid. The cavity preparation of a GIC filling is the same as a composite resin. GICs are chemically set via an acid-base reaction. Upon mixing of the material components, no light cure is needed to harden the material once placed in the cavity preparation.
Towards the GIC end of the spectrum, there is increasing fluoride release and increasing acid-base content; towards the composite resin end of the spectrum, there is increasing light cure percentage and increased flexural strength. Dental compomers, also known as polyacid-modified resin composite, are used in dentistry as a filling material.
Opposed to this, direct composite filling pastes shrink a few percent in volume during hardening. This can lead to shrinkage stress and rarely to marginal gaps and failure. Although improvements of the composite resins could be achieved in the last years, solid inlays do exclude this problem. [3]
All-in-one self-etch adhesive and a single component universal adhesive, used in the adhesion of direct and indirect dental restorations. Also known as a "bonderizer" bonding agents (spelled dentin bonding agents in American English) are resin materials used to make a dental composite filling material adhere to both dentin and enamel.
Amalgam filling on first molar. In dentistry, amalgam is an alloy of mercury used to fill teeth cavities. [1] It is made by mixing a combination of liquid mercury and particles of solid metals such as silver, copper or tin.
Dental materials such as filling and orthodontic instruments must satisfy biocompatibility requirements as they will be in the oral cavity for a long period of time. Some dental cements can contain chemicals that may induce allergic reactions on various tissues in the oral cavity.
