Dental composites. Glass ionomer cement - composite resin spectrum of restorative materials used in dentistry. 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.
The dental LED curing lights use LED’s that produce a narrow spectrum of blue light in the 400–500 nm range (with a peak wavelength of about 460 nm), which is the useful energy range for activating the CPQ molecule most commonly used to initiate the photo-polymerization of dental monomers." [6]
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 ...
In dentistry, the configuration factor (or c-factor) refers to the number of bonded surfaces in an adhesive dental restoration.Because adhesive dental restorative material will adhere to the walls of a cavity preparation made available to it during polymerization, competing forces can arise during restoration of the tooth that can have both short and long term effects that correlate to the ...
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.
After the prefabricated post is properly cemented into the post space, a core material, such as dental composite, can be packed around the cemented post. After the material has been cured or has had a chance to set and properly formed into a crown preparation, an impression can be taken for the fabrication of a prosthetic crown.
