Endodontic surgery with bone graft: apicoectomy of left maxilar lateral incisor

ABSTRACT In cases where endodontic treatment is unsuccessful, endodontic retreatment is usually the first option for clinical management. However, it is possible for periapical infection to persist. Eventually, these apical infections reach inaccessible locations, requiring surgical intervention. Female patient, elderly, diabetic, without other comorbidities and allergies, presented a persistent circumscribed and well-defined periapical bone defect around the root apex of the left maxillary lateral incisor (#22), with disruption of the buccal and palatal bone plates, with no signs of regression after six months of endodontic retreatment. The objective of this paper was to demonstrate the stages of endodontic surgery − apicoectomy of an upper left lateral incisor, with bone graft and collagen membrane, both of bovine origin, as well as six months’ postoperative follow-up. It can be concluded that endodontic surgery performed with bovine bone graft and collagen membrane showed therapeutic success, considering a six-month follow-up period. Periodic clinical and radiographic follow-ups are strongly recommended for the assessment of endodontic surgery success.
