I understand that we have to place the implants in the ant. areas ideally at the cingulum area, is that the same you do for the Mandibular anterior as well? i am wondering since the upper & lower Ant have limited bone availability & we have to place them in a projection angle that gives screw access on the palatal (of course there those cases that crowns need to be cemented), how do you place your upper or lower Ant implants (at what projection)?
