CAMLOG ROOT-LINE 2 Surgical Procedure

21 CAMLOG ® ROOT-LINE 2 IMPLANT DRILLING SPEEDS The drill speed depends on the diameter. The recommended speed is 800– 300 rpm depending on the drill type (handpiece angle reduction ratio 16:1–20:1). The recommended maximum drilling speed for thread tapping is 15 rpm (handpiece angle reduction ratio 70:1–100:1). The tap adapter for the torque wrench also permits manual tapping. COOLING 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 drilling technique. The pilot drills, pre-drills, and form drills are good for 10–20 drilling cycles. If exces- sive force has to be applied because of a dull drill, then change the drill immediately to prevent bone overheating. The lower edge of the depth mark is the reference for the preparation depth. CAUTION The maximum apical extension length of the drill is 0.6 mm.
