How to Place Neighboring Implants Parallel to Each Other (Part IV)?

Implants at the site of #3 and 5 were placed for Kent a month earlier.  Immediately before placing a third one in between, something had been done for the first two implants in preparation for guidance.  Can you guess what that is?

Hi! Dr. Wei, 
Answer: May be the Guide Pins were used in the Implant Well after opening the Implant Screws for the parallelism.

Good thinking.  Post guides (0 degree) can be inserted to the wells of the implants after healing screws are removed. Pay attention to special terms assigned by implant companies.
