Spark erosion procedure: a method for extensive combined fixed and removable prosthodontic care.

Restoration that uses a combination of fixed and removable partial dentures, which involves precision attachments and telescopic procedures, represents one of the highest levels of functional and esthetic therapy. In the past, these restorations were mostly made with high gold-content alloys. The dental spark erosion procedure offers a sophisticated method for using base metal alloys for these complex restorations. This procedure combines the functional and esthetic advantages of precision restorations with the advantageous properties of base metal alloys such as low thermal conductivity, high strength, and lower cost.
