title: Spark erosion: a sophisticated technique to solve a difficult problem.
abstract: Even with the most careful planning, situations arise that require sophisticated treatment alternatives. The Milled Bar, of which the spark erosion bar is one type, is described in detail. A two-degree tapered meso (primary) bar with anterior friction pins attached to osseointegrated implants provides frictional retention when supporting a secondary bar with swivel lock attachments. The two components of the prosthesis are accurately associated with each other using spark erosion and plasma arc welding technology.
