ARTICLE IMPLANT Ø IN MM MATERIAL J3021.4300* J3021.6000* J4013.1601 J4013.2001 Polishing protection for caps and bases for bar abutment Lab prosthetic screw for bar abutment, hex, brown anodized 3.3/3.8/4.3 5.0 3.3/3.8/4.3 (Thread M1.6) 5.0 (Thread M2.0) Titanium alloy Titanium alloy The finished bar must be seated tension-free on the bar lab analogs. After completing the bar construction, the final bar prosthesis with base reinforcement 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. INSERTING THE BAR CONSTRUCTION The finished bar construction is transferred to the bar abutments and screw-retained finally with new unused blue anodized prosthetic screws, using a screwdriver, hex, with 15 Ncm. The newly created full denture is then inserted and checked for proper fit. POLISHING PROTECTION FOR CAPS AND BASES FOR BAR ABUTMENT A polishing protection can be used to protect the delicate edges of the caps and bases during trimming. The polishing protection is fixated to the cap or base with the aid of a lab prosthetic screw for bar abutment. 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.
