Impression Protocol for ZBLC Crown or Immediate Implants

1. X-Ray of Stock Abutment, Custom healing abutment, or Temporary Crown

The X-ray provides essential diagnostic information regarding the precise positioning of the abutment in relation to the implant and surrounding bone. This information is critical for selecting the appropriate abutment and for designing an optimal emergence profile of the final crown.

2. Pre-op scan of Stock Abutment, Custom Healing Abutment, or Temporary Crown

Performing a pre-operative scan of the healing abutment is essential (refer to Tip 1), the scan provides a precise digital record of the soft tissue contours around the healing abutment. This is crucial for designing the emergence profile of the final crown in a way that maintains the exact marginal ridge of the healing abutment and therefore minimizes the risk of disturbing the tissue.

3. Soft Tissue and Scanbody Scan for Final Impression (Full Arch)

Remove the tissue former or healing abutment (refer to TIP 2) and immediately perform a scan of the sulcus to capture the detailed contours before the soft tissue begins to collapse. Following this, proceed with the scanbody scan. This step is critical for accurately designing the soft tissue support and ensuring the optimal emergence profile of Zero Bone Loss Concept (ZBLC) crowns.

4. Scan Opposing (full arch)

A full-arch scan provides comprehensive information about the patient's bite and occlusion. This is essential for ensuring that the implant restoration integrates harmoniously with the opposing teeth and the patient's overall bite, preventing any occlusal imbalances or excessive forces on the implant.

5. Scan Bite (ask patient to bite HARD)
