Implant placed too close to natural tooth: treatment options?

I have a new patient who presents with an implant placed in the maxillary second premolar site (OSSTEM TS3) that is almost in contact with the maxillary first molar natural tooth. When I uncovered the implant, there was not enough proximal space to place a cover screw because the implant is so close to the molar. I ground the mesial surface of the maxillary molar to create sufficient space for the cover screw. I recommended to the patient to have intentional root canal treatment in the molar so I could prepare the tooth for a crown and create adequate space for a crown on the premolar implant. I have created enough room to seat the abutment. But the abutment is in contact with the mesial surface of the molar and there is no room for the crown. What other treatment options do I have? Would an angulated abutment work here?

Maybe construct the crown with the abutment integrated and screw it in, assuming you might be able to do this?

your options are limited: 1. flatten contacts on adjacent teeth to gain a little bit more room 2.not sure why you would need to do intentional endo to provide additional room, but restoring adjacent teeth is another but imho not great way to deal with it. 3. as someone mentioned, a screw in crown may be able to be designed to fit the area. 4. but probably the best option, and the one you least likely want to here, is explant and replant. if you were building a house, wouldn't you want the foundation in the proper place. that's why implantology has to be considered a restorative discipline. first, the position of the crown is determined. second, the position of the supporting elements, be they implants or otherwise is determined. third, the presence or absense of adequate supporting bone to position the implant correctly is evaluated. if there is inadequate bone, then you have to grow some or modify the treatment plan. hope it works out. gary

From what you are describing, I do not think and angulated abutment will help with the seating issue. It may be that the implant needs to be removed and placed more ideally? If you could post a radiograph, that may help with providing a solution.

Keep the tooth vital, remove the implant and start over again.

Kind of difficult to comment when there isn't any image to look at.

Can't comment without an x-ray and a photo would also be useful.

agree with Paolo. From what you say, even if you manage to get a crown on the implant, the restored implant will be very difficult for the patient to maintain and you'll possibly end up removing the implant following a great deal of messing about with periimplant disease then grafting to regain bone and periodontal membrane and starting the whole process again. It sounds like the least painful way forward is to retrieve the implant and, if you can do this atraumatically, place a replacement implant in a better position...

meant to add...remove the implant atraumatically and place the new implant during the same appointment.

Could you post a picture? Quadrant ortho?

Only one good option: remove the implant. Using a surgical guide establishing the proper location of an implant in regards to the proper position of the tooth to be replaced, place a new implant. A host of problems will ensue if you try to restore this wayward implant.

I don't know how any one can give any sort of meaningful advice when the OP hasn't provided any photos or radiographs. I realize people want to be helpful but any advice without photographic or radiographic evidence isn't worth the bits it's written on :)

Would recommend doing a screw retained crown the lab can then have metal only on the distal due to the minimal space and fuse porcelain to the other surfaces this will allow a better restoration in this situation then a crown cemented on an abutment.

If there is enough space in root area don't remove it .reshape molar and make a special abutment

Remove the implant, graft, and replace with a new implant in the proper position. Even if you can restore the implant, it will likely be difficult to clean, may lead to bone loss and decay on both the implant and the adjacent tooth, and eventual loss of both adjacent tooth and implant. Don't start with such a compromised situation unless you want long-term maintenance problem.

Radiographic image would be necessary to discuss further. Sounds like replacement of the implant would be good option. Once you restore the implant crown over the implant which was not place by you, your patient will think about the " implant treatment was done by you who took care of the implant last time..." so you may have to maintaining the compromised situation for years. If there is no good space to restoration, maybe no good space to prophylaxis space and it will lead to periimplantitis. Better to discuss with patient well and start over it.

Expand width if the distal tooth shifted? Why is there insufficient space after there was enough room for placement? Open coil spring with a few ortho brackets to open length required. Or short term clear aligned therapy.... just sayin

Screw retained crown on the implant. Or Have you thought about pushing the molar distally orthodontically? Specially if the1st molar was tilted mesially & if there is no 2nd or 3rd molars ... I believe this option safer than removing and placing new implants

Hello colleagues, I apologize in advance if my comment would be long because the case should be thought about. Regarding the comments we have 6 with removing the implant and replant against 4 trying to find different solutions. I am 60 years old dentist and placed my first implant in 1992 which was a blade not a screw implant and I have seen many cases similar either my own cases or not , this always happens more when you insert the implant immediately after extraction because the socket guides you or if the place is not very accessible to view your insertion axis of course now you can use a surgical guide .First of all we need an x ray to see if the implant is close to the next tooth all the way or gust inserted with an angle to decide using straight or angled abutment . let's think loudly if the implant is in the aesthetic zone which is not our case , well integrated or not , if the patient can afford to remove the implant and re insert another implant , if you are quite sure to do it successfully and get another good placed and integrated implant , or just trying to correct the condition. The good sign is you could already attach the abutment , so if you decide not to remove the implant you can always reshape your abutment as if you are preparing a natural tooth of course without sacrificing the gum condition and put the hygiene into consideration. Listen guys abutments can always play with to fit your condition , to reposition the finishing line or to correct the alignment according to each case. I hope this helps and good luck

I will suggest you to create enough space by using opening coil spring ( bound bracket to the first molar and and the first premolars and use a segment wire ) in this way you wouldn't need to do RCT for first molar and you don't need to remove the implant too ..
