Intentional replantation of severely compromised teeth

Aim: The present case series aims to show the applicability of intentional replantation to successfully solved cases with root perforations, external cervical resorption, and chronic pain due to material extrusion to the periapical tissues. Summary: After medical and dental history review, the signs, symptoms and imaging examinations were analysed in order to perform a correct diagnosis. All cases had indication for intentional replantation procedures which were addressed according to the best practices. The teeth were extracted in the most atraumatic way possible while avoiding the handling interaction with the periodontal ligament. Hard tissues repair was conducted by using ultrasonic tips and mineral trioxide aggregate (MTA) application before getting the teeth positioned back in their original socket. Extra-oral time was less than 15 minutes and the operating microscope was used in all cases. After a period of two years all teeth were asymptomatic and functional.
