WHAT ARE THE SUGGESTED SOLUTIONS?
Avoid using attachments!
Bond attachments then scan and plan.
Etching template as suggested by some clinician, I saw Dr J Cope using it.
I heard Dr D Walt mentioning what is called Trial-insert (see the slides below).
MY PERSONAL OPINION
I did not try option 4 but I assume it will take extra time.
I have used option 3, it is a good option, requires etching template but the AFs were reduced significantly.
We are currently researching option 2 in an in-vitro study.
