Simultaneous Retrieval of Root Fragment, Sinus Lifting With Particulated Bone Graft, and Immediate Dental Implant Insertion.

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. A simultaneous oro-antral communication was also repaired in 2 patients. Sinus membrane elevations and retrieval of a root fragment via the lateral wall sinus approach were also performed. After repairing a membrane perforation with a particulated graft, an immediate implant insertion was done. An average period of 41 months of clinical and radiographic follow-up revealed a healthy maxillary sinus and a functional implant in the tooth area.
