1. Use minimal soft tissue material and maximum stone around the implant analog.
2. Choose an appropriate non-shouldered or shouldered abutment that will allow for a minimum of 2.0mm and a maximum of 5.0mm thickness of polyceramic material.
3. Confirm size appropriateness of abutment on soft tissue model.
4. Mark height of gingival contour on the abutment with a red felt tip marker.
5. Insert the abutment into the abutment preparation holder and mark a subgingival line around the abutment. The subgingival line should be 2.0 to 4.0mm below the red gingival contour line.
6. Make gross preparations to the abutment with a cutting disc.
7. Make final preparation with a carbide bur.
8. Examples of partially prepared and finished abutments.
9. Prepared abutments on model.
10. Use 6.0mm tall stealth shouldered abutment when implant is 2.0 to 4.0mm sub-crestal and the 8.0mm tall stealth shouldered abutment when the implant is 4.0mm or more below the crest of bone.
