Preheating resin composites enhances their stiffness, marginal adaptation, and microhardness. This novel technique improves material handling but does not affect flexural strength, while reducing polymerization shrinkage.
Area of Science:
- Dental Materials Science
- Polymer Chemistry
Background:
- Resin composites are widely used dental restorative materials.
- Optimizing handling and clinical performance of resin composites is crucial.
- Preheating unset resin composite materials is an emerging technique.
Purpose of the Study:
- To review laboratory experiments on preheated resin composites.
- To evaluate the impact of preheating on mechanical properties.
Main Methods:
- Systematic literature search for laboratory studies on resin composite preheating.
- Analysis of reported mechanical properties and handling characteristics.
Main Results:
- Preheating improves degree of conversion, stiffness, marginal adaptability, and microhardness.
- Flexural strength remains unaffected by preheating.
- Polymerization shrinkage is reduced with preheating.
- Microleakage data is currently inconclusive.
Conclusions:
- Resin composite preheating offers significant benefits for material properties and handling.
- Further research is needed to fully understand microleakage implications.
- Preheating is a promising method for enhancing clinical outcomes with resin composites.
