Hey guys just my 2 cents here:

I prefer to go slightly deeper even with a BLT implant (others may classify this as subcrestal) and to obtain this I usually leave an extra 1-1.5mm of space just in case. For example cbct shows 10mm depth available, so I choose an 8 or 8.5mm implant, prep the zone with guide drill to approximately 9-9.5mm, place an 8-8.5 in there but I don’t stop as soon as I reach bone level, rather I go slightly further in knowing I have extra space to work with and in the end it looks like the tip is at a total of 9-9.5mm while the connection point is about 1mm or so under bone level.

In your specific case with your example I’m assuming the implant “lost grip” because of 2 reasons: either it reached max depth and capitulated lol or most probably bone stability may not have been fully achieved after extraction surgery (maybe you didn’t wait long enough or maybe the new bone that formed there was much more spongier and thus softer than you expected)

Would love to see if anyone agrees with this or maybe they have a better explanation
