40 OCCLUSALLY SCREW-RETAINED PROSTHETICS ON CAMLOG ® AND CONELOG ® BAR ABUTMENTS After completing the bar construction, the final bar prosthesis with base re- inforcement out of metal is fabricated in the usual manner. The teeth are positioned based on the principle of modern full dentures. An existing full denture can also be converted into a bar-retained prosthesis with suitable bar matrices. IMPORTANT NOTE The matrix should be placed before fabrication of the prosthesis using a suitable relief wire. Only then is vertical translation of the prosthesis on the bar ensured. ART. NO.

The newly created full den- ture is then inserted and checked for proper fit. BASE FOR BAR ABUTMENT, SOLDERABLE Soldered bar construction with prefabricated bar bases made of solderable gold alloy. The bar base is fixated on the bar lab analog using a brown an- odized lab prosthetic screw for bar abutment, hex. The height of the bar base is 5.3 mm.
