Overview Of Placement Of Amalgam Restorations Teeth That Require In general, amalgam alloy consists of silver 40% minimum, tin 32% maximum, copper 30% maximum, zinc 2% maximum, and sometimes traces of indium or palladium. in preamalgamated alloys, mercury 3% is used which react more rapidly when mixed with mercury. mercury used for dental amalgam is purified by distillation. An occlusal cavosurface bevel is contraindicated in the tooth preparation for an amalgam restoration. 38 it is important to provide an approximate 90 to 100 degree cavosurface angle, which should result in 80 to 90 degree amalgam at the margins. 31 this butt joint margin of enamel and amalgam is the strongest for both. amalgam is a brittle.
16 Complex Amalgam Restorations Pocket Dentistry Amalgam. dental amalgam is a metallic restorative material composed of a mixture of silver–tin–copper alloy and mercury. the unset mixture is pressed (condensed) into a specifically prepared undercut tooth form and contoured to restore the tooth’s form and function. when the material hardens, the tooth is functional again, restored with a. The dental amalgam is a restorative material that has been used for a long time to restore teeth affected by the caries disease. although there is a huge discussion about its use nowadays due to the presence of the mercury and the unfavorable esthetics, it is still largely used around the world to restore posterior teeth, especially because of its versatility, low cost, and excellent physical. The preparation of the vertical surrounding walls of the occlusal box parallel to each other may lead to an insufficient volume, on the restoration margin of an nonadhesive amalgam restoration, to resist the masticatory load, especially on those teeth with the higher cuspal slope inclination ( fig. 6.32a, b) [4, 49, 51]. Indications. complex posterior amalgam restorations should be considered when large amounts of tooth structure are missing and when one or more cusps need capping (fig. 16 1). 1 complex amalgams can be used as (1) definitive final restorations, (2) foundations, (3) control restorations in teeth that have a questionable pulpal or periodontal.
