Mechanical properties and specific dental cements
- Fracture toughness and thermocycling effects on fracture toughness.
- Compressive strength and differences between automixed and hand-mixed resin-based cements.
- Examples of cements with high compressive strength.
- Specific information about Zinc Polycarboxylate cements, including their invention, use in dental appliances, composition, and pulpal irritation.
Dental cements have a wide range of dental and orthodontic applications. Common uses include temporary restoration of teeth, cavity linings to provide pulpal protection, sedation or insulation and cementing fixed prosthodontic appliances. Recent uses of dental cement also include two-photon calcium imaging of neuronal activity in brains of animal models in basic experimental neuroscience.
Traditionally cements have separate powder and liquid components which are manually mixed. Thus working time, amount and consistency can be individually adapted to the task at hand. Some cements, such as GIC, can come in capsules and are mechanically mixed using rotating or oscillating mixing machines. Resin cements are no cements in a narrower sense, but rather polymer based composite materials. ISO 4049: 2019 classifies these polymer based luting materials according to curing mode as class 1 (self-cured), class 2 (light-cured), or class 3 (dual-cured). Most of the commercially available products are class 3 materials, combining chemical- and light-activation mechanisms.
