lowshrinkage
Lowshrinkage, often written as low-shrinkage, describes materials that exhibit reduced volume change during processes such as curing, drying, or solvent evaporation. The term is applied in several fields, notably dentistry, where polymerization shrinkage of resin-based composites and cements can affect restoration integrity, and in construction, where shrinkage affects coatings and cementitious systems.
Shrinkage occurs from polymerization, solvent loss, or moisture loss; measurement is typically reported as volumetric shrinkage
In dentistry, low-shrinkage composites include silorane-based systems that shrink less due to ring-opening reactions, as well
Advantages of lowshrinkage materials include improved marginal integrity, reduced residual stress, and better long-term durability. Trade-offs
Research continues to optimize polymer chemistry, filler technologies, and processing protocols to achieve lower shrinkage without
