Single-tooth osteotomy for intention replantation.

The conventional replantation technique has many drawbacks. The tooth may break during extraction; thus, teeth with diverged or curved roots are not good candidates for such a procedure. The occurrence of root ankylosis after replantation, with subsequent resorption, does not permit the replanted tooth to support any additional load, such as an orthodontic appliance or to be used as a bridge abutment. The procedure described here is designed to eliminate these drawbacks. The technique is based on leaving the delicate periodontal ligament fibers intact and transferring the wound created to the bone tissue. Extraction is achieved by a single-tooth osteotomy with the hope of improving the success rate of replantation.
