8856P is a fine grit, tapered chamfer, round diamond bur. 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.

8856P is a part of the Pin-Diamonds® family - diamond instruments with guide pin for controlled tissue-preserving crown preparation. Other features and benefits include:

• Conical chamfer, round - Produces a cutting depth of 0.30 mm (size 016), 0.38 mm (size 018) or 0.54 mm (size 021) at the edge of the crown.
• 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.

Indications for Use:

Crown and veneer preparation.
