Immature Third Molar Autotransplantation for Replacement of Tooth Row Defects
Objectives: Autotransplantation of third molars with unformed roots has several biological benefits: preservation and regeneration of bone, providing a functioning tooth, with no need for biomaterials.
The aim of the study was to investigate the efficiency of autotransplantation of the immature third molars, performed in the Institute of Stomatology, Riga Stradins University.
Methods: There were 22 patients (7 males and 15 females, mean age 17,9 years, range 14 - 22) with 26 immature third molars autoransplantations. Out of them in one patient tree teeth were transplanted. In two patients two teeth were transplanted. Only first transplanted tooth was included in research. Procedures were performed from 14/08/2019 till 03/08/2020 by the same specialist. Only patients with at least 6-month observation period were included.
Three teeth from the maxilla to the maxilla, eight teeth from the maxilla to the mandible, nine teeth from the mandible to the mandible and two from the mandible to the maxilla were transplanted.
Gingival pockets and vitality tests for transplanted teeth were assessed clinically. Bone attachment, obliteration of pulp chamber, root length growth and possible appearance of root resorption were evaluated in the periapical radiographs.
Results: An increased gingival pocket of 6-8 mm was observed in two cases. Positive vitality test was assessed in 10 teeth, delayed response- in 6 teeth, no response in 6 teeth.
Radiological examination revealed reestablishment of the bone attachment in 20 teeth. Pulp chamber obliteration was observed in 13 teeth. Root continues to grow in length in 6 teeth. Internal root resorption was detected in 1 case.
Conclusions: Autotransplantation of the immature third molars could be considered as effective method for replacement of missing molars. Further development for method using 3D printed replicas and evaluation of long-term results is under way.
