CONELOG PROGRESSIVE-LINE Surgical procedures

16 CONELOG ® PROGRESSIVE-LINE IMPLANT DRILL SPEEDS Depending on the drill type and diameter, the maximum drill speeds (350-800 rpm) vary according to the table. (handpiece angle reduction ratio 16:1–20:1). The maximum speed for taps is 15 rpm (contra-angle reduction 70:1- 100:1). The tap adapter for the torque wrench also permits manual tapping. The lower edge of the depth mark is the reference for the preparation depth. COOLING OF DRILLS The cooling occur through external irrigation on the angled hand piece with sterile saline solution (pre-chilled to 5°C/41°F). DRILL LIFE Drill longevity depends on bone quality and the drilling technique. The pilot drills and form drills are good for 10–20 drilling cycles. If excessive force has to be applied because of a dull drill, then change the drill immediately to prevent overheating of the bone. CAUTION The maximum apical extension length of the drill is 0.5 mm.
