What is a composite resin restoration?
Composite resin fillings are made of plastic and glass compounds, which can be colour-matched to the tooth being restored, giving it an aesthetic advantage over the silver colour of amalgam. Newer formulations of these materials have improved their capacity to withstand stress and wear.
What is a micro hybrid composite?
Prime-Dent® Micro-Hybrid Composite A light-cured resin-based dental restorative composite which contains approximately 76% by weight (60% by volume) inorganic filler with an average particle size of 0.7 microns. Ideally suited for anterior and posterior restorations.
What is microfil composite?
Renamel Microfill composite combines beauty with long-lasting color stability and wear-resistance. It is the only composite that is properly pigmented with just the right amount of opacity, translucence and fluorescence to mimic the enamel surface.
How do you polish composite resin?
Final polish of the composite resin surface to its most lustrous finish can be accomplished using disks with the finest aluminum oxide abrasive. Using a disk will not only smooth the resin surface, but will also heat the surface, creating a high luster.
What are resin restorations?
A Preventive Resin Restoration (PRR) is a thin, resin coating applied to the chewing surface of molars, premolars and any deep grooves (called pits and fissures) of teeth. More than 75% of dental decay begins in these deep grooves. Teeth with these conditions are hard to clean and are very susceptible to decay.
What is the difference between an amalgam restoration and a composite restoration?
The major difference between the two types of fillings is in the color. Composite fillings are made from materials matching the color of your teeth whereas amalgam fillings are made from metal.
What is hybrid resin?
Hybrid resin is a composite resin made from more than one of materials. We successfully develop and market of following hybrid resins, based on our unique composite technology. Search by Product. High-performance adhesive for paper tubes.
What is packable composite?
Packable: Packable composites were developed to be used in posterior situations. Unlike flowable composite, they exhibit a higher viscosity thereby necessitating greater force upon application to ‘pack’ the material into the prepared cavity.
How do you make composite restoration shiny?
To give the composite resin a natural enamel-like glossy look, it is recommended to use a small-grain diamond pastes or aluminum oxide pastes. These pastes should be applied with a felt disc or a soft-brushed brush, to not scratch the surface of the composite resin.
Can you polish composite bonding?
This type can always be polished off. However, dentists that are not highly attuned to aesthetic issues will be uncomfortable doing that. In some cases, composites will absorb stain, which means that the stain penetrates into the material. This, naturally, can’t be polished off.
How is a Class II posterior composite restoration done?
The typical Class II posterior composite restoration is “placed on blind faith” using techniques and armamentarium designed specifically for amalgam placement. It is extremely difficult to evaluate the quality of composite layering in an interproximal preparation that is between the buccal and lingual line angles and thus, not clinically visible.
What’s the best way to use composite resin?
Traditionally, clinical placement of composite resins has utilized a 2mm increment technique. This approach was recommended to decrease the effects of polymerization shrinkage on the material during light curing, and to assure curing light penetration to the entire resin depth.
What are the main clinical issues with composite resins?
The main clinical issue with bulk placement of composite resins appears to be the depth of polymerization – does the material at the base fully cure when placed in increments larger than 2 mm?
What kind of resin is used for dentin replacement?
Bulk fill (up to 4 mm) flowable composite resins have been clinically used for several years and are traditionally designated as “dentin replacement”, reducing the number of increments required in posterior composite restorations.
