Parallel chamfer, round - Creates a cutting depth of 0,65 mm at the crown margin
Crown Preparation | Pin-Diamonds Diamond instruments with guide pin for controlled tissue-preserving crown preparation. Advantages: Guide pin as &ldquohorizontal distance keeper&rdquo: For circular material reduction the guide pin guarantees controlled preparation with an even cutting depth. This way a uniform preparation is created, avoiding the &ldquogutter&rdquo effect. Controlled preparation of a defined crown margin. Guide pin as &ldquovertical distance keeper&rdquo: 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.
