Tapered chamfer, round - Creates a cutting depth of 0.30 mm (size 016), 0.38 mm (size 018) or 0.54 mm (size 021) at the crown margin 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 of a defined crown margin.
• Guide pin as "vertical distance keeper": During the preparation of 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 of the alveolar bone) is largely avoided.
