What is self-curing composite?
C-R Hybrid is a multi-purpose, self-cure composite that features deep curing and controlled shrinkage towards the tooth. The result is a restoration that exhibits less internal stresses than a light-cured restoration. C-R Hybrid is polishable and available in a universal shade to work in most deep preparations.
Is composite material light-cured or self cured?
The light-cured composite resin is indicated for shallow facial restorations and veneers. The self-cured composite resin is indicated to restore deeper cavities, those with a dentinal gingival margin, and for occlusal restorations.
What is self-cure in dentistry?
Any resin that can be polymerized by chemical catalysis rather than by application of heat or light; used in dentistry for dental restoration, denture repair, and impression trays.
What happens to a composite when it is cured?
The process of curing of composite resins occurs in three main phases: pre-gel, gel point and post-gel. During the pre-gel phase, the material may flow and undergo molecular rearrangement, in order to compensate shrinkages forces. During this phase, there is a predominance of linear polymer chains.
What is self cure?
noun. A cure effected by a person suffering from a disease, disorder, etc., without medical intervention; (also as a mass noun) the action or practice of curing oneself without medical intervention. Earliest in figurative context.
What is dual cure composite?
Dual-cured resin composites have been mainly used as a core material for the reconstruction of non-vital teeth (13), and as dentin substitute in the open sandwich filling technique (11,14).

What does self cure mean?
How long should you cure composite?
Practitioners were astonished by how quickly these lights cured restorative composites. On average, the recommended exposure time to cure an increment of a light-coloured composite was between 3 and 5 seconds.
What is the curing time of composite?
They recommended using 60 seconds of light cure with an intensity of at least 400 mW/cm2 for each 2-mm layer of composite. More recently, in 2013, Ilie and others31 suggested that when using an LED curing light, a minimum of 20 seconds should be used for a 2-mm layer of composite.
What does dual-cure mean?
dual-cure res·in a resin that uses both light and chemical initiation to activate polymerization.
