23 OCCLUSALLY SCREW-RETAINED PROSTHETICS ON CAMLOG ® AND CONELOG ® BAR ABUTMENTS The impression is cast with suitable model material and the impression posts may not loosen. After curing, the impression is removed and the impression posts loosened from the lab analogs. TIP: We recommend that you fabricate the cast with a gingival mask. The surrounding gingiva is represented true to the situation, particularly for subgingival crown margins and restorations in esthetic areas. An op- timal design of the crown contour is easier to achieve. TIP: After removing the impression, the bite registration caps can be attached on the impression posts in the cast for mounting. The bite reg- istration taken before the impression is then placed on the caps and the cast mounted. Bite registration cap CAST FABRICATION WITH CAMLOG ® IMPRESSION POSTS, OPEN TRAY After the impression is taken, the CAMLOG ® Impression posts, open tray, are in the impression. In the dental laboratory, the CAMLOG ® Lab ana- logs corresponding to the diameters are attached to the impression posts, open tray (note proper seating). A screwdriver (hex) is used to hand-tighten the fixing screw. The impression is cast with appropriate model material. After curing, the impression posts are loosened from the lab analogs and the impression is removed.
