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. Another common problem caused by an ill-fitting metal substructure is breakage of retaining screws or abutments, and in the most severe case, the implant itself can be fractured. Spark erosion overdentures meet the requirements for esthetics, phonetics, retention, and support and also allow accessibility for proper patient oral hygiene. Günter Rübeling introduced this technique to the field of implant dentistry in the mid 1990s. As shapes that are difficult to machine occur frequently in toolmaking, it is not unusual to find a good toolmaking workshop equipped with a Spark … This process erodes very small metal particles from the inside of the metal substructure, starting from the areas that first come into contact with the lab analogs.

Spark erosion refers to the technology that is used to fabricate a bar within a denture which is attached with a very intimate fit to a metal substructure. Passive fit of implant-retained prosthetic super-structures improved by electric discharge machining. Each screw access hole should be milled exactly with the trajectory of the supporting implant, as described in the following steps: One way to achieve a passive fit in the metal substructure is to make the substructure in multiple segments, connect these pieces in the patient’s mouth, and make an index of the whole piece. dental implants with a defined degree of surface roughness, typically 1 to 100 micro metres, employs spark erosive techniques. There is decreased stress on the work piece due to the cooling action of the di-electric fluid. After finishing the spark erosion process, if all of the retaining screws are tightened without milling the screw access holes, there will be a load concentration throughout the retaining screws (, 6. Lineham AD, Windeler AS. An extremely thin work piece can be machined without distortion as no mechanical forces are created. Tighten all of the retaining screws before spark erosion and milling of the metal substructure (, 4. The milling depth can be adjusted by changing the measurements on the milling machine’s micrometer (, Inaccurate impression technique or material, Dimensional changes in stone model during setting, Dimensional changes during casting procedures, Dimensional changes after porcelain veneering in cases of fixed bridges.
