There are several possible causes of failure following nonsurgical and surgical endodontic treatments. Many of the causes of these failures can be attributed to the presence of endodontic-periodontic bone loss around roots. The development of guided-tissue regeneration (GTR) procedures in periodontal therapy has let to the successful treatment of some types of periodontal bone loss. These GTR procedures can be adapted for use in endodontic surgery to produce success in cases that previously presented a poor prognosis. this study categorizes all of the different clinical situations in which GTR procedures can be used to treat endodontically related bone loss. Case reports of several categories are presented.
