Dental restorative materials that are applied, while pliable, to a tooth or teeth and can be adapted, carved, and finished are classified as:
direct restorations
The dental restorative materials that are applied in a pliable form, and then adapted, carved, and finished are classified as “Direct restorative materials.” These materials are called direct restoratives because they are applied directly inside the patient’s mouth within the given clinical situation.
Common direct restorative materials include dental amalgam, composite resin, glass ionomer, and temporary materials such as zinc oxide-eugenol and intermediate restorative materials. These materials are used to restore function and esthetics to teeth that have been affected by caries, erosion, or trauma.
The application of direct restorative materials usually involves cleaning and preparing the damaged tooth or teeth before placement, and then placing the material in the cavity or defect. The material can then be adapted to the tooth structure, carved to fit the natural shape of the other teeth in the patient’s mouth, and finished to a smooth surface.
It is important to note that direct restorative materials have varying degrees of durability and resistance to wear over time. Therefore, the choice of material is dependent on several factors, such as the location of the tooth or teeth in the mouth, the extent of the damage, the patient’s oral hygiene and diet, and the aesthetic expectations.
