Dental Materials
The condensation reaction in silicone elastomers produces ethyl alcohol, which evaporates during setting, contributing to the material's contraction.
17624
Dental Materials
Microfilled composites contain very fine silica particles (0.04 to 0.2 µm in diameter), which give them excellent translucency and a high surface area for better filling of small restorations.

Dental Materials
Fabrication of ceramics and metals like titanium that are difficult to cast, is done by CAD-CAM process and copy milling.
67068
Dental Materials
Camphorquinone is a photosensitizer that absorbs blue light and initiates the free radical polymerization of the resin when irradiated, leading to cross-linking and setting of the composite.
33789
Dental Materials
Ceromer is a composite material that combines the benefits of glass ionomers and composite resins. The inclusion of ceramic fillers and fluoride releasing fillers in a polymer matrix gives Ceromer its unique handling properties and enhances its restorative capabilities.
82247
Dental Materials
A condenser that is considered user-friendly typically has a high elastic limit and high springiness, allowing for better control and easier placement of the restorative material.
33422
Dental Materials
An excessive amount of amine initiator can lead to a faster reaction rate and a decrease in the depth of cure, as the light may not be able to penetrate deep enough into the material to activate the entire polymerization process.
