Best Technique for Removing an Osseointegrated Implant?

Dr. Y. asks:
I have a patient with an implant fixture that has over 4 threads exposed from horizontal bone loss. The implant is osseointegrated and is not mobile. It is 13mm long. What is the best technique for removing the implant? Trephine out the implant with a trephine bur? Use forceps like the extraction of an erupted tooth?

Forceps scary idea , if it must come out then trephine (difficult with some types of implant) or better use the SLA system with reverse torque of up to 400 Nm.

I use Piezosurgery remove implant the same with remove root ankylosis.

Dear colleagues I do remove implants easily and very conservatively with the Rerievel! No damage,no bone loss!

Please describe conditions, why are you removing the implant?

Anyone had luck electrosurging it, waiting a week and reversing it out?

Impant removal become easier after retrievel tool by Nobel. Remerber that all implants ever tested presents removal torques, so it´s is possible. Some conditions may require cut one implant side along the interface removing more implant than bone parts, then retrievel tool or forceps are less traumatic.

why are you going to remove the implant? it has already 11mm in bone and has osseointegration!!!! please tell more about the situation.

I agree - forceps is a very scary scenario with an integrated implant. You have a higher risk of fracturing the surrounding bone - even the alveolus or mandible (if thats where the implant is).Keep it gentle and conservative with a trephine. Good luck.

I would try to detox and graft this implant first.

I would only try grafting if the implant has 3 walls of integration. I have used a trephine or a 701 tapered fissure bur with success. Horizontal bone loss is inherent with some implant systems, and they are coming back to haunt me 10 to 14 years after placement.

If not an esthetic problem, reduce the pocket and maintain should be first option.

Exposing four threads is not an indication for explantation but I am sure dr Y has other reasons for removing the implant. In my opinion trephines are the worst possible way to remove an implant. You get a lot of bonenecrosis because of overheating. If you have laser or a piezo that is what I would use to remove enough bone untill you can remove the implant by counter torque or forceps. If you don't have one of these you can just use a small round bur. Removing an implant by forceps although it sounds a lot more risky it is much more gentle to the surrounding bone than a trephine. Good luck

regarding implant removal. As I recall, there were some comments (nicely done) using electrosurge. I would like to see some photos and if successful (no major bone loss) the technique

I think Nobel retrieval is a good choice (no need to remove bone) but sometimes using piezo in some extent around the implant to help (mainly mandibular). BUT is realy necessary to remove? There are some sugestions and considerations above to maintain the implant. I never used electrosurge because I think the damage to the sorrounding bone could be unpredictable. But I know that some colleagues use it.
