Root Fragment: Removal and Grafting of Defect

The apical portion of the fixture on the other hand was affected by an inflammatory process detectable on radiography as a radiolucent area. The presence of a probable root fragment, detectable as an imprecise radiopaque mass in the zone where the implant was later placed, confirms the probable bacterial etiology of this case of IPL. On the other hand, in case number 2, the presence of IPL around the fixture was solved by surgically removing the implant apical third as well as the adjacent tooth apex. It may be concluded from our histological examination that removal of the apical portion of the fixture should be considered an effective treatment for IPL since the remaining implant segment remains optimally osseointegrated and capable of continuing its function as a prosthetic abutment. Careful attention, however, is required at the implantation planning stage to identify in advance any sources of infection in the edentulous area of interest which might compromise the final outcome.

The aim of these 3 patient reports is to demonstrate a new technique for the reconstruction of the posterior maxilla in patient of a displaced root fragment. The retrieval of root fragments, sinus floor augmentation procedures with a particulated graft, and an implant insertion were performed in the same operation.

Through the buccal window, sufficient access was provided to remove RF atraumatically with maximal retention of surrounding bone that led to predictable implant placement.
