Removal of the residual root and implant therapy simultaneously via bone lid approach

Residual root fragments in posterior mandibula after extraction are often rarely seen. Implant treatment presumes that implants are placed in bone, without any contact with root. At ankylosed teeth, complete root removal is often invasive; subsequently, the sites require additional augmentation procedures to complete the treatment. Different techniques can be used for removal of these residual root fragments. To our knowledge, there are no study in the literature to provide the extraction of the root fragment using bone lid technique and achieve implant rehabilitation at the same time. The aim of the present study is to reduce bone loss during the residual root extraction for implant therapy. The bone lid approach is an easy and safety technique that could be performed to remove the residual root fragment and achieve implant rehabilitation at the same time. Future studies involving long-term follow-up are needed to evaluate the permanence of these results.
