Self Healing Dental Composites

The SHDC is based on an existing self-healing material model and uses biocompatible, cement-forming chemistry and stronger silica microcapsules. It heals cracks by forming a clinically tested dental restorative material, glass ionomer cement (GIC). In Self Healing Dental Composites (SHDCs), GIC (Glass ionomer cement) is produced when two healing components, "healing powder (HP)" and "healing liquid (HL)," come into contact and react. The healing of engineered composite materials, such as self-healing dental composites(SHDCs), has primarily focused on the recuperation of fracture toughness after activation of the polymer catalyst. As a result, evaluations of the self-healing efficiency of dental composites have primarily been focused on fracture toughness. However, bulk failure of the restoration can occur due to fast fracture, and cracks can reach a critical length due to cyclic crack extension.
