What type of material combines the properties of glass and resin?

The material that combines the properties of glass and resin is glass ionomer. Glass ionomer is a versatile dental material that is made from a powder of glass (silicate) and an organic acid, which results in a material that exhibits the benefits of both parent components.

One of the key features of glass ionomer is its ability to release fluoride, which can help strengthen enamel and prevent caries, making it particularly advantageous in certain clinical situations, such as in pediatric dentistry or in patients with a high risk of cavities. Additionally, glass ionomer adheres well to dental tissues, which enhances its utility for restorations or for use as a liner under other restorative materials.

Composite materials, while they can incorporate various components including resin and fillers, do not specifically combine glass with resin in the same way that glass ionomer does. Other choices like amalgam and silicate do not possess the same characteristics or properties as glass ionomer. Amalgam is a metallic mixture primarily composed of silver, mercury, tin, and copper, while silicate is more of a historical material that had applications in the past but lacks the modern advantages provided by glass ionomer.
