Crown Preparation | Pin-Diamonds®
Diamond instruments with guide pin for controlled tissue-preserving crown preparation.
Other features and benefits include:
- Tapered chamfer, round 856P 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.
- 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 preparation.
