That radiolucency that you refer to is most likely the result of him wallowing out the osteotomy as he tried to hand torque it further…by actually reading the original post I am able to gather the facts surrounding this particular case rather than just being critical of the final result. If you look closely at the PA you will notice that there isn’t even a cover screw in it and if you read the post he states that it was just done a few days ago. These two pieces of information are enough to tell me that the image was taken way too soon after placement to accurately asses the “bone loss”.
We need 4mm of tissue between the free gingival margin and the platform of the implant to satisfy the biologic width requirement and to get crestal bone stability. The implant is at least 2mm supracrestal, that means that the patient would need 6mm of tissue thickness over the crest, which is super unlikely. Big complications happen when we ignore small complications. This is not a big deal to fix. Tell the patient that you don’t love it the way that it is and that you would appreciate it if they would let you try to get a new implant in better position. Then if they allow you to, I’d go a good 4mm deeper than the current implant, which should put you 2mm subcrestal. You will need to profile the bone a little bit to allow for proper emergence.
If you leave that implant, you’ll regret it every time the patient comes in for hygiene with inflamed tissues of peri-implantitis. If restored as it is, there’s no room to build the proper emergence, so you’ll end up with the dreaded Tomato on a stick restoration that will be a food trap. Food traps lead to peri-implantitis. It may last three, four or five years until it eventually fails, but then you will have a much bigger defect to deal with.
You are right, I didn’t realize that the X-ray was immediately post-op but that doesn’t change one word of my response. This implant is way off where it needs to be and should be removed.
This is from an immediate placement that was done today. One rule of thumb for placement depth (for conical connection) in molars is to get the platform level with the furcation of the adjacent molar. This allows for development of proper emergence so you don’t have food trap issues. It also contributes to crestal bone stability when we have at least 4mm of highly polished Zirconia against the tissues.
if you just placed it a couple days ago. i would just have pt return. remove implant. drill 3-4mm deeper and place the same implant you dont need a new implant at the correct dept. either equicrestal or subcrestal. you are atleast another 6mm from the sinus floor plenty of room.
not a big deal at all. just osteotomy deeper and torque down the same implant. with the correct drills you should get 35Ncm torque again. no bone graft needed.
you over torque it. that probably why your torque dropped to 15Ncm. over torque can cause bone necrosis. good luck.
dont leave the implant like that. not a big deal. drill deeper. you already have a hole. work is half done.
