Glass ionomer cements are commonly used in:
- Restorative fillings: Especially in areas where esthetics and durability are essential, such as in fillings for primary (baby) teeth.
- Crown and bridge restorations: As a luting material that holds crowns or bridges in place.
- Temporary fillings: For short-term restorations while more permanent solutions are being prepared.
- Base or liner: To provide thermal insulation and protect the pulp of the tooth.
Key Drivers of Glass Ionomer Cement Market Growth
1. Increasing Awareness of Oral Health
With an increasing emphasis on maintaining oral health, especially in developed countries, there has been a rise in demand for high-quality dental materials.
