Objective of this study is to present the topic, possibilities and longterm evaluation of successes and failures of autotransplanted premolars, followed up until 30 years. This study investigated a consecutive group of one hundred patients treated with autotransplantation caused tooth aplasia and tooth loss. All patients (9.2 – 14.4 years, mean 12.8) had one-rooted premolars transplanted from one region to another. Totally 118 premolars were transplanted in root stages with an open apex wider than 1 mm. Marginal gingiva was transferred with both papillae. Transplantation induced tooth eruption and bone induction. Transplantation of one-rooted premolars carried out by a trained oral surgeon had a long-term success of 91.5%. The method can therefore be taken into account for orthodontic treatment planning.
