title: When to use fillers, build-ups or posts and cores.
abstract: After preliminary tooth preparation for crowns, all previously placed tooth restorative material should be removed from teeth before making final tooth preparations. Small areas of missing teeth should be replaced with fillers (compomer); larger pieces of missing teeth should be replaced with build-ups (bonded composite resin or bonded amalgam); and endodontically treated teeth with half or more of the coronal tooth structure missing should receive a titanium or titanium alloy post and core and a bonded composite resin or bonded amalgam build-up.
