The aim of the present case is to describe the use of autologous platelet-rich plasma (PRP) in an intentional replantation procedure for a periodontally involved lower right central incisor with 18 months follow-up. Brief information is also given on the preoperative preparation of PRP in the dental office. PRP preparation is a new biotechnology, and the prepared material contains thrombocyte concentrates and high levels of growth factors. This material promotes healing time in a range of various sites. In this case, a tooth with severe periodontal breakdown was treated with PRP with intentional replantation procedure. This tooth was previously treated with root canal treatment and root planing. The tooth was extracted, and was replanted with autologous PRP. Clinical and radiographic follow-up for 18 months demonstrated new bone formation around the apical portion of the root and all clinical parameters indicated a trend of healing. The mobility of this previously grade III mobile incisor returned to normal limits. We speculate that intentional replantation with PRP application may induce wound healing and may induce bone formation.
