Long-term Outcomes of Autotransplantation of Teeth: A Case Series.

The aim of autotransplantation of teeth (ATT) is to replace a lost tooth with a functional tooth within the same patient. Although it has recently become more of a recognized and viable treatment approach in dentistry, the long-term outcomes are still not well-documented. The principal author (M.T.) has performed more than 1000 ATTs for reasons such as treating missing teeth, deep caries, poor endodontic results, and periodontitis over the past 30 years in private practice. During the course of private practice, 2 separate analyses were performed on a total of 319 cases with follow-up ranging from 2-26 years. The results showed a tendency toward higher success rates in younger patients; the success rate was highest in ATTs performed on immature teeth (about 95%), about 90% in patients younger than 30 years of age and approximately 80% in patients older than 30. The failures were most often caused by replacement resorption (ie, ankylosis-related resorption). The purpose of this case series was to show successful long-term outcomes of ATT as well as to provide clinical insights and describe tendencies noted over the course of 30 years of performing ATTs.
