POM: Polyoxymethylene BASE FOR BAR ABUTMENT, CAST-ON Cast bridge or bar versions with prefabricated bar base made of high-melt- ing cast-on alloy and burn-out plastic screw channel (POM) for cast-on technique. The bar base is fixated on the bar lab analog using a brown an- odized lab prosthetic screw for bar abutments, hex, corresponding to the diameter. The plastic screw channel of the bar base can be shortened occlusally to the height of the screw-retained prosthetic screw. The overall height of the base is 13 mm. WAX-UP The bar wax-up is created based on the planning directly on the burn-out plastic screw channel and bar base. The wax thickness over the plastic screw channel should be at least 0.3 mm. The bar base consists of a non-oxidizing alloy. Do not cover the delicate edge of the base with wax. Prefabricated bar components made of wax/plastic can also be used to fabricate a pre-milled bar construction. CAUTION Do not cover the fine gold margin of the bar base with wax. This can lead to a surplus of casting alloy on or over the margin of the base on the implant shoulder support.
