Sulcus Zeroing Technique
A New Biological Approach to Gingival Sulcus Management
A technique developed to rethink sulcus management during prosthetic procedures and simplify the clinical workflow from the temporary restoration to the impression.
The Concept
Reinterpreting the Gingival Sulcus
The precision of an impression depends not only on the material used or the scanning technology but primarily on what we can make visible and recordable. The Sulcus Zeroing Technique emerges from a different approach to managing the gingival sulcus: intervening on the relationship between preparation, provisional, and soft tissues to create favorable conditions for recording the prosthetic margin. A protocol that integrates:
From Preparation to Impression
The Rationale of Preparation and Margin Management
The Provisional as a Tool for Tissue Management and Conditioning
Sulcus Management According to the Sulcus Zeroing Protocol
Analog and Digital Registration of the Result
A single protocol. A single biological concept. A different approach to impression taking.
