What are the direct restorative materials?

Direct restorative dental materials include amalgam, resin-based composite, glass ionomer, resin modified glass ionomer and acrylic.

What is a direct restoration?

Direct Restorations: Direct restorations refer to any restoration that can be entirely fabricated directly inside the mouth during a single dental appointment.

What are direct tooth colored materials?

There is a range of directly placed tooth-coloured restorative materials available to the dentist. These materials form a continuum that links resin based composites to glass ionomer cements, with resin composite at one extreme and glass ionomer cement at the other and two hybrid materials in between (Figure 7.1).

What is the significance of direct restorative materials to operative dentistry?

The main advantage of direct restorative materials, i.e. dental amalgam and resin composite, is shorter chair time. Dental amalgam is a material very used for restorations in posterior teeth 33, presenting adequate resistance to masticatory forces 13,32.

Are there any direct and indirect restorative materials?

But the advent of these new materials has not elimi- nated the usefulness of more traditional restorative materials such as gold, base metal alloys and dental amalgam. Overview.This report outlines important features of direct and indirect restoratives, with an emphasis on the safety and efficacy of each material.

What are the prequisites for dental restorative materials?

Dental restorative materials are required to fulfill basic prerequisites including similarity to tooth structures in their mechanical, physical, and esthetic properties.

How are restorative materials used to replace teeth?

Restorative materials are used to partially or entirely replace teeth structures considering clinical issues which can occur due to oral diseases (e.g. caries and periodontitis) and trauma [1–7]. A. Zabrovsky, Y. Houri-Haddad, in Biocompatibility of Dental Biomaterials, 2017

What happens to the restorative material after placement?

After placement, dental restorative materials are in constant interaction with the surrounding tissues. Although dental restorative materials are fabricated to be as durable and inert as possible, restorations may deteriorate, degrade or fail, and during these processes, constituents of these materials may be released into the oral cavity.
