Hello. In some cases where we not sure how gingiva would behave after fixing custom abutment, doctor need to scan modified abutment. Ti abutment are difficult to scan in lab and with TRIOS its real nigthmare. For now we sandblast abutment and give it to dentist.
Anyone tried to anodize Ti to make more scanable? What color TRIOS loves most?

Why don't you try zirconia custom made abutment, zirconia abutments are superior to titanium and Gold especially if you're working in the esthetic zone !

i suggest using a scan body with the Trios.
Revisit your design for custom abutments and focus on improving the emergence profile .
Your time is better spent doing a split file than finding a workaround.

Is the dentist providing an emergence scan?

Scanning (or impressing for that matter) an abutment in the mouth is a bad idea to begin with -you started with the best margins we ever make in a lab )the margins we actually fabricate ON a restorative abutment instead of a copy of it) And you move to the worst margins we ever make… Because of how tissue behaves around an abutment. R.K.M. is correct put the scan body back in and scan that after the tissue has calmed down Then modify your abutment margins if needed and create the emergence profile from the final restorative position.

Zirc abutments are not an upgrade they are a compromise and I regularly refuse to do them because titanium abutments have such a low failure rate as to be statistically zero, whereas zirc abutments have double digit failure rates.

Such situations appers when we try to press tissue much above of diameter of healing abutment. Its surgical problem which sometimes Doc put on lab.
So when we put scan abutment and rescan tissue profile will back (not always).
So you suggest to print new model with new tissue and fix abutment manualy? or mill new one?

Why not make a custom temp or healing cap that will shape the tissue to the exact contour you require?
Then rescan the new tissue contour.

Sounds good. but in 80%-90% cases abutment fits ok, and we dont have such troubles.
