In the study 26 premolars were transplanted in 20 patients after traumatic dental injury (n=10) or tooth aplasia (n=16) in the upper front. Standard clinical parameters were evaluated. Based on a standardized photo documentation, the relative soft tissue level was measured in comparison to the healthy adjacent teeth. Radiographic findings involved the evaluation of root resorption, pulp canal obliterations and the relative bone height. Patient satisfaction was determined using a standardized questionnaire.
