 Abstract
Purposes: The aim of this study was to evaluate pulp healing, periodontal healing, root development of autotransplantation of immature third
molars and show its viability in treatment of early loss of tooth in young patients
Materials and methods: In this article we performed a retrospective study with 41 transplanted teeth in 36 patients. The Mean age at the time of
surgery was 17 years(range 13~24 years) and mean postoperative follow up period was 2.4 years(range 1~6 years)
We evaluated the survival rate, pulp healing, periodontal healing, root development of the above teeth
Results: At the last examination 40 teeth among 41 transplants were still present so survival rate was 97.6%. The pulpal healing was found in 38
teeth of 41 transplants. The periodontal healing was found in 38 transplants. The continuous root development was seen in 38 transplants.
Conclusions: From the above results, the autotransplantation of immature third molars was found to be a useful and reliable treatment method for
early loss of teeth in adolescents and young adults.
Keywords: Autotransplantation, Immature third molar, Pulp healing, Periodontal healing, Root development
