CAMLOG ROOT-LINE 2 Surgical Procedure

63 CAMLOG ® ROOT-LINE 2 IMPLANT TEMPORARY CROWN/BRIDGE, CHAIR-SIDE The temporary abutment is mounted to the implant and acrylic material se- cures the temporary crown/bridge (strip crown) to the temporary abutment. To prevent acrylic material from flowing into the screw channel, the chan- nel can be sealed with wax in advance. TEMPORARY CROWN/BRIDGE, LAB-SIDE The temporary restoration can also be fabricated in the dental laboratory on the working cast based on the procedure for fabricating temporary so- lutions similar to those used in conventional crown and bridge restorations. INSERTING THE TEMPORARY ABUTMENT Thoroughly clean and dry the inner configuration of the implant prior to in- serting the temporary abutment. Insert the temporary abutment into the implant and rotate it until the cams engage with the implant grooves. After hand-tightening the abutment screwwith a screwdriver, hex, seal the screw channel with an easily removable material. Do not use composite since drill- ing it out would be required in order to remove the screw. Make sure that the screw channel is not overfilled; the surface should be concave. The temporary crown or bridge is mounted to the customized temporary abutment using temporary cement. All cement residues must be removed. NOTE The insertion directions of the abutments, indicated by the implant axial direction, rarely match. For this reason, bridge structures should not be fabricated in one piece (firmly attached) with the temporary abutment. The temporary abutments are first screwed on the implants, then the temporary bridge is mounted (passive fit). Customized temporary abutment on the working cast
