Failing or Ailing Implant?

This patient had an implant placed in #10 site. About a month or so after the implant was placed, infection set in and caused some bone loss.  You can see the bone loss and deep pocketing around the implant in the radiograph. No bone graft was performed by the surgeon (Was that a mistake?)

I am trying to determine if this implant is failing or ailing? Long term, the concern is bacteria getting caught up in the pockets around the implant and leading to infections and long term success may be compromised. What do you think? What do you recommend that I do at this point?

    This implant is going to have serious problems sooner or later. Since the healing screw is still in place, I would remove it, let it heal and start over again.

  2. OMFS says:

    In view of the fact it is an esthetically important area and only 1 month post-op, I would remove the implant, allow for healing, and reconsider treatment at a later date. Personally, I would recommend an Astra implant because of their demonstrated decreased loss of bone in long-term follow up. This is a very difficult location to place implants and depends on quality of bone. Possibly a maryland or conventional bridge could be used.

    • S Low says:

      If this implant has no mobility, flap it and determine the degree of osseous resorption. Then make a decision to do implant repair and or extract.

      • paolo rossetti says:

        i would not repair anything. flap elevation would compromise the vascularity of the site and possibly would induce an additional soft/hard tissue resorbtion. not to metion the papillas… just unscrew it.

      Hello OMFS
      As my interest is bone and I have little interest in implantdesign I am not up on current research on the long term results of different implants. I use Astra implant and they perform beautifully for me but if you have access to a reference that compares long term results of different implants it would be appreciated if you could post this reference. Thank you.

      Actually OMFS,

      It has been over a year since the initial implant surgery. After the surgery, maybe 2 months after the surgery, infection set in and antibiotics were prescribed to halt the activity. Unfortunately, bone loss occurred and now it is as such. Also, would you have recommended a bone graft in that area? # 10

  3. Gregori Kurtzman, DDS, MAGD, FACD, FPFA, DICOI, DADIA says:

    I would agree with my fellow practitioners. Remove the implant and graft the site to try and get the bone level to the CEJ of the adjacent teeth. Allow it to heal 8 weeks then if the graft looks good on the radiograph place a new implant at the proper depth doing additional grafting if needed. Cases in the esthetic zone shouldnt be rushed if you want an esthetic result.

  4. Jim says:

    The elephant in the room, regarding removing or grafting, is the buccal position of the implant and where the buccal and lingual bone levels are. I would also like to know if this was an immediate extraction/placement or 2 stage.

    • aungken says:

      Great question, this was actually a two stage implant. An extraction was initially done on the tooth and allowed to have the site healed for 6 months. Then the implant operation was done. Initially, the implant was fine and level. However, after an infection set in, the bone around the implant dissolved. As you can see pockets abound, just waiting for bacterial colonies to increase.

      • Ed Dergosits says:

        Why was the implant placed 6 months after the extraction? This gave the ridge time to resorb. Using an implant with a platform switch is always a better choice.

  5. Kevin Frawley says:

    It would be important to see the immediate post op xray to know how much bone has been lost. Also what does the tissue look like now? Does it match the adjacent teeth esthetically? Is there any inflammation? Also how many months post op are you now? You said the infection happened at one month….
    I think all these factors need to be considered before deciding what to do.

    • aungken says:

      Kevin, thanks for the insightful questions. I shall find the post op X-rays to see how much bone was lost. At the moment the site is tender and sensitive 1 year after the initial implant. It is not bleeding by any means, but the when probed, there is a noticeable reaction.

  6. Gregori Kurtzman, DDS, MAGD, FACD, FPFA, DICOI, DADIA says:

    Ok will change my recommendation as i thought the original post implied its been in a month. At this point I would flap it place a flat healing screw, use a laser if available to clean any exposed threads, treat the exposed threads with citric acid gel rinse cover the entire implant and cover screw with a putty graft material (APRF better if available) place a long term collagen membrane get primary closure. Allow to heal for 3-4 months then uncover. can temp it during this by bonding a piece of ribbond across the lingual and build pontic out of composite.

    • aungken says:

      Dr. Kurtzman,

      Thank you for the great advice. I think these are great recommendations to at least prolong the possible life of the implant. I did want to try and have grafting material put in there to get it back to the pre-infection state where there was more bone around the implant. Also implant was # 7 not 10. My mistake.

      I am also uploading the pre-infection photos to so can actually see how it was before some of the bone was destroyed. These are post implant photos, right after original surgery.

      • Gregori Kurtzman, DDS, MAGD, FACD, FPFA, DICOI, DADIA says:

        You have a little bone loss and upon flapping may see more threads on buccal exposed but would still follow the decontam steps I suggested. Key IMHO is getting primary closure over entire cover screw which means a wide flap that is mobilized to lay tension free over the crest.

        Is the patient a smoker? that may have contributed or whatever provisional present was bouncing on the healing abutment placed at implant placement.
