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.

Maxillary removable partial overdenture within Locator Root Attachment in a retained root: a case report

If maintaining oral few retained root when planning the removable prosthesis, it is possible to obtain a more comfortable and functional result. In this case report, ‘Locator Root Attachment’ was used to maxillary removable overdenture in patients with a few teeth and retained root. A functionally proper clinical result from attachment after clinical and radiographic analysis was observed in this case.
