CAD/CAM Preparation Bur Kit

An atraumatic placement of the crown margin is one of the important parameters for the dental health of teeth after restoration. Sub-gingival restoration margins can result in an irritation of the marginal periodontium. For that reason, intrasulcular crown margins should not be more than 0.5 mm under the sulcus so that connective tissue and epithelial attachment remain unaffected.

Guide pin burs support an atraumatic preparation since they keep a pre-defined distance to the perodontium. Furthermore, the guide pin can prevent the gutter effect. The guide pin ensures a safe and uniform cutting depth and a controlled preparation of a defined crown margin.

This kit contains 7 Multilayer Diamond instruments. The black coded egg is recommended for easy shaping of palatal and lingual area. The guide pin burs with medium grit are used for a first grindng of a tooth, the fine guide pin burs for the smoothing of the rough preparation surface.
