— The present investigation is a clinical and radiographic study of 76 auto‐transplantations of third molars. The observation period ranged from less than one up to six years (average 3.7 years). In 58 cases the teeth were transplanted after extraoral root filling whereas 18 teeth were transplanted without endodontic intervention. At re‐examination of the transplanted molars the marginal and the periapical conditions were examined clinically and radiographically. Third molars transplanted without root filling showed significantly less progressive root resorption and less increase in pocket depth as compared to teeth transplanted after extraoral root filling. A multivariate analysis was applied to examine the relationship between 17 clinical factors and the dependent variables ‐ progressive root resorption, pocket depth, and periapical radiolucency ‐ in 56 teeth transplanted after extraoral root filling. Progressive root resorption was found in 44 cases (79%), and this complication was found significantly related to the variables approximal grinding of donor tooth, extraoral period, and observation period. Increased pocket depth around the transplant was registered in 30 cases (52 %) and found significantly related to the period of splinting. Periapical radiolucency was found in 16 cases and was significantly related to the variable extraoral period.
