CAMLOG Vario SR Prosthetics Components

CAMLOG ® VARIO SR PROSTHETIC COMPONENTS 30 | 31 Vario SR plastic copings, bridge, with Vario SR prosthetic screw May be shortened by up to 5.0 mm Height 11.0 mm VARIO SR ANTIROTATIONAL MECHANISMS For single crown restorations on straight CAMLOG ® Vario SR abutments, plastic copings with three antirotational surfaces in the inner configuration are used. For single crown restorations on angled CAMLOG ® Vario SR abutments, plastic copings with one antirotational surface are used. For bridge and bar constructions on straight and angled CAMLOG ® Vario SR abutments, plastic copings with round inner configuration are used. EXAMPLE OF FABRICATING A FINAL BRIDGE RESTORATION To fabricate a bridge restoration, Vario SR plastic copings, bridge, are set on the Vario SR analogs and fixed using the Vario SR prosthetic screw. The copings can be shortened occlusally by 5.0 mm. WAX-UP The framework is waxed up in the usual manner according to the design of the “reduced crown shape”. Take care that adequate and uniform ceramic or plastic layer can be achieved for the veneering. The wax thickness over the plastic coping should be at least 0.3 mm. Do not mold over the delicate coping edge. IMPORTANT NOTE When burning out the casting muffle, swelling may occur due to the thermal expansion of the plastic and damage the investment compound in the area of the plastic coping. This can cause investment compound to be included in the casting metal. Therefore, a minimumwax thickness of 0.3 mm should be applied to the plastic coping. When heating, the wax softens first and gives the plastic enough space to expand.
