CONELOG SCREW-LINE surgical procedures

22 CONELOG ® SCREW-LINE IMPLANT FORM DRILLING Diameter- and length-specific form drills are available for each implant size. The form drills are color-coded and laser-marked. The form drills included in the surgery sets are supplied with a color-coded removable depth stop. This must only be used with form drills SCREW-LINE. Depending on the specified drilling depth (implant length), the hole diame- ter is expanded progressively with the series of form drills until the inten- ded implant diameter is achieved. The small graduations in diameter achieve a gentle preparation of the bone. Recommended drilling speeds: Ø 3.3 mm, 550 rpm Ø 3.8 mm, 500 rpm Ø 4.3 mm, 400 rpm Ø 5.0 mm, 350 rpm PERFORMING FORM DRILLING Performing form drilling using CONELOG ® SCREW-LINE as an example implant size Ø 4.3 mm, L 13 mm: 1.
