Introduction:
Intentional replantation is a reliable and predictable treatment for cases in which nonsurgical endodontic retreatment failed or is impractical and endodontic surgery is hampered because of anatomic limitations.
Methods And Results:
This article presents a protocol for intentional replantation illustrated with some interesting cases. The cases presented here are from patients (average age, 61 years) with no contributing medical history. The cases are molars with previous failed endodontic treatment/retreatment and diagnosed with apical periodontitis. Treatment procedures included atraumatic extractions with minimal manipulations of the periodontal ligament, followed by root-end resection, root-end preparation with ultrasonic tips, root-end fill with bioceramic cement, and rapid tooth replacement into the socket. Granulomatous tissue was gently curetted when applicable. All procedures were performed under the microscope.
Conclusions:
Intentional replantation with careful case selection may be considered as a last option for preserving hopeless teeth. Atraumatic extraction by using state-of-the-art equipment, instruments, and materials, minimal extra-alveolar time, and maintaining an aseptic technique are key factors for success.
