Evaluación de un nuevo método de remoción quirúrgica de implantes oseointegrados considerados en fallo

Abstract

Objective

The aim of this study is the evaluation of a new removal method of osseointegrated implants under a minimally invasive technique.

Material and methods

The study was conducted on a group of 66 osseointegrated internal and external connection implants that were considered unsuccesful. The surgical removal was indicated after radiologically confirming peri-implant bone loss, and poor positioning which made the prosthetic rehabilitation impossible, or would damage the prosthetic implant retainer. The surgical procedure was developed in an operating room under local anesthesia. As first surgical removal option, the procedure consisted of the use of a removal instrument that works against torque and which does not need a full thickness flap to reach the surgical site; and as a second surgical removal option a trephine bur was used. For this option, a full thickness flap was performed in order to expose the surgical site.

Results

A total of 66 osseointegrated implants were removed under the first mode, with no full thickness flaps or Trephine burs required.

Conclusions

Within the limitations of this preliminary study, we propose that the use of this new, against torque, removal instrument of osseointegrated implants in failure is seen as a very good alternative to invasive surgical removal techniques, reducing surgical risks.
