Objective. The purpose of this study was to present a new surgical preservation technique for teeth with incomplete vertical root fracture.
Study design. Seventeen patients with 1 endodontically treated maxillary anterior tooth in which an incomplete vertical root fracture involving only the buccal side was suspected underwent a flap elevation procedure to visualize the pattern of bone loss and assess the type of root fracture. If the preoperative diagnosis was confirmed, a groove following the fracture line was prepared using retro-tips driven by an ultrasonic device and sealed with mineral trioxide aggregate after filling of the bone defect with calcium sulfate.
Results. A total of 10 vertical root fracture repair procedures were performed. At 12 months' follow-up, all cases showed clinical and radiographic success. After 33 months, 7 patients were available for a follow-up: 5 cases remained successful, and 2 teeth (lateral incisors) failed.
Conclusions. The present surgical approach for preservation of teeth with incomplete vertical root fracture demonstrated satisfactory results regarding clinical outcome. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2010;110:e45-e52)
