CAMLOG Vario SR Prosthetics Components

CAMLOG ® VARIO SR PROSTHETIC COMPONENTS 36 | 37 The bar elements are cut accordingly and in consideration of a joining gap that is as small as possible fitted between the Vario SR bases for bar. After assembling all the components, the bar segments are laser-welded together with the Vario SR bases for bar under sufficient argon gas purging and the bar are high-gloss polished. IMPORTANT NOTE ABOUT LASER-WELDING Blue discoloration on the welds must be avoided. This points to insuffi- cient purging with argon gas and to oxygen uptake of the titanium. Brittleness and associated weakness in the weld is the result. Observe the operating instructions of the laser devices used! After completing the bar construction, the final bar prosthesis with base reinforcement made out of metal is fabricated in the usual manner. The teeth are positioned based on the principle of modern complete dentures. An existing full prosthesis can also be converted into a bar-retained pros- thesis with suitable bar matrices. IMPORTANT NOTE The matrix should be placed before fabrication of the prosthesis with a suitable relief wire. Only then is vertical translation of the prosthesis on the bar ensured. INSERTING THE BAR CONSTRUCTION The finished bar construction is transferred to the CAMLOG ® Vario SR abut- ments and with new unused Vario SR prosthetic screws, fixed with 15 Ncm using a screwdriver (hex). The full prosthesis is then inserted and checked for proper fit.
