AUTOTRANSPLANTATION OF 45 TEETH TO THE UPPER INCISOR REGION IN ADOLESCENTS

Young, growing individuals with one or more upper incisors missing due to trauma, agenesis or extraction of abnormal teeth can be treated wi th. autotransplantation to restore aesthetics and function and to pres erve the volume of the alveolar process. Studies have been performed t o evaluate the prognosis, indicating a good prognosis, especially if a n immature transplant is available, developed to 3/4 of the full root length. The purpose of this study was to analyse the result of all aut otransplantation of teeth performed to the upper incisor region betwee n 1979 and 1990 at the Department of Oral Surgery, Eastmaninstitutet, Stockholm, Sweden. The material consists of 23 immature and 22 mature teeth in 40 patients with a mean age of 12 years. They were systematic ally followed up clinically and roentgenologically for up to four year s after surgery. 22 of the 23 immature (96%) and 18 of the 22 mature t eeth (82%) were observed to be without serious complications. The comp lications occurred, with one exception, within the first year of obser vation. The conclusion drawn from this study is that autotransplantati on to the upper incisor region can be performed with a good prognosis, both for mature and immature teeth.
