A Parallel Algebraic Multigrid Preconditioner Using Algebraic Multicolor Ordering for Magnetic Finite Element Analyses

A dental implement for dispensing and compacting amalgam includes separate dispensing and compacting assemblies at opposite ends of a handle. The assemblies each have an amalgam carrier cooperating with a plugger portion which extends from an end of the handle. A spring-biased lever maintains the amalgam carrier in a normally lowered position capable of receiving amalgam. Each assembly features a lock for releasably retaining the amalgam carrier in a raised position whereby the plugger portion extends beyond its respective amalgam carrier for tamping the amalgam into a tooth cavity.
