(1) Background: Three-dimensional printing is progressing rapidly and is applied in many\nfields of dentistry. Tooth autotransplantation offers a viable biological approach to tooth replacement\nin children and adolescents. Restoring or reshaping the transplanted tooth to the anterior maxilla\nshould be done as soon as possible for psychological and aesthetic reasons. However, to avoid\ninterfering with the natural healing process, reshaping of transplanted teeth is usually delayed\nthree to four months after transplantation. This delay creates a need for simple indirect temporary\naesthetic restoration for autotransplanted teeth. The aim of this study was to develop and validate a\ndigital solution for temporary restoration of autotransplanted teeth using 3D printing. (2) Methods:\nFour dry human skulls and four dry human mandibles were scanned using cone beam computed\ntomography to create 3D models for 15 premolars. Digital impression of the maxillary arch of one of\nthe skulls was captured by intra oral scanner. The digital work flow for the design and fabrication\nof temporary veneers is presented. The seating and adaptation of the 3D printed veneers were\nevaluated using stereomicroscopy and micro-computed tomography. (3) Results: Evaluation of the\nveneer seating using stereomicroscopy showed that the mean marginal gap at all of the sides was\nbelow the cut-off value of 200 micron. The overall mean marginal gap was..................
