Tapered chamfer, torpedo - Creates a cutting depth o 0,38 mm (size 018) or 0,54 mm (size 021) at the crown margin Product name: 8878KP.FG.018 pack unit 5 For use: Crown Preparation Size: 018 Size D: 018 1/10 mm Length L: 8.0 mm Length L1: 0.5 mm Max. rotational frequency: 160000 Angle: 2° Package unit: 5 Crown Preparation | Pin-Diamonds® Diamond instruments with guide pin for controlled tissue-preserving crown preparation. Advantages: - Guide pin as “horizontal distance keeper”: For circular material reduction the guide pin guarantees controlled preparation with an even cutting depth. This way a uniform preparation is created, avoiding the “gutter” effect. Controlled preparation o a defined crown margin. - Guide pin as “vertical distance keeper”: During the preparation o a subgingival margin the 0.5 mm long guide pin assures that a pre-defined distance to the periodontium is kept. Damage to the biological width (the area at the coronal side o the alveolar bone) is largely avoided.
