Ok, so I always place my Neodent subcrestal. I was told that leaving the implant in the cortical layer of.bone will cause resorbption. Its important to drill deeper than you intend. It also depends on density. If I were placing a 1st molar in a healed site I would drill to 10 mm with 2.2 drill then drill to a 5.0 at 8mm then place a 5×8. I have found that this will allow me to get the 1mm subcrestal. I have had spinners. Its important to remember that a spinner will integrate. I’ve been burned too many times with putting healing abutments on immediately. <div>
