Long Term Clinical Success of Immature Third Molar Autotransplantations with 3D-Printed Replicas

Objectives.
To evaluate the clinical outcomes of third molar autotransplantations in 52 patients over a two-year follow-up period.
Methods.
From August 2019 to September 2022, a total of 52 patients (aged 12–22 years; mean age 16.9 years) were included in this study. The study consisted of 18 males and 34 females with immature third molars classified as development stages 3–5 according to Moorrees.
Patients were selected based on the need for permanent molar extraction and the presence of at least one non-erupted third molar. All procedures were performed at the Institute of Stomatology, Riga Stradins University, Latvia.
Clinical outcomes were evaluated at 24 months and included assessments of tooth mobility, bleeding on probing, and periodontal pocket depth.

Results.
Of the 52 patients assigned to interventions, 57 teeth were evaluated. All teeth had 100% survival at 2 years. At 2 year, the percentages were as follows: mobility- 1 out of 57 teeth (1.75%), bleeding on probing- 2 out of 57 teeth (3,51%), periodontal pockets—3 out of 57 teeth (5,26%)
Conclusions.
Third molar autotransplantation shows promising success over a two-year period with favorable clinical outcomes. Further research is recommended to optimize protocols and improve long-term success rates.
