![]() This step substantially reduces extraoral time, particularly in multirooted teeth where replantation into the socket is challenging. A small field of view CBCT scan not only provides the clinician with a 3D assessment of the area of interest, but also the possibility of segmenting the donor tooth and of manufacturing a 3D-printed tooth replica (19, 20). Key patient information required consists of anatomic shape, root development of the donor tooth, bone dimension of the recipient socket, as well as compatibility of both the size of the donor tooth and the recipient site. Three-dimensional (3D) cone beam computed tomography (CBCT) radiographic assessment of teeth and their surrounding structures is desirable to plan an autotransplantation procedure (18). The main benefits of this technique include enhanced esthetics, dentofacial development, proprioception, and dental arch integrity (17).Īutotransplantation candidates must be carefully selected using clinical and radiographic information. ![]() Indeed, early orthodontic forces improve prognosis of autotransplanted teeth (16). The presence of PDL allows both the continued formation of bone and soft tissue in the recipient site (13) as well as orthodontic tooth movement (14, 15). Unlike dental implants, successfully autotransplanted teeth behave identically to natural teeth (11, 12). ![]() Hence, the steady rise in autotransplantations in recent years. It is recommended therefore to avoid or at least limit dental-implant placement in growing patients, as implants would end up in infraposition (7, 8). This situation is more likely to take place in growing patients, particularly those with a long facial type (3-6). As a result, implant placement in the anterior zone can produce an esthetic compromise due to an implant infraposition caused by progressive growth of the alveolar process in the neighboring teeth and a lack of periodontal ligament (PDL) in the dental implant. Although this growth is more pronounced in the second and third decade of life, it continues in the fourth and fifth decades. Furthermore, alveolar growth in the anterior maxilla does not stop after pubertal growth peak, but continues throughout the patient’s life. Adverse outcomes associated with implants are largely related to prosthetic (technical) failure and to persistent infections surrounding implants (2, 9, 10). This technique was developed as a therapeutic option for teeth loss due to trauma, decay or congenital tooth agenesis, yet fixed dental prostheses and, above all, dental implants, saw its use decline among clinicians.ĭecades of problems and complications with implantology have led to reevaluation of tooth preservation and traditional clinical techniques (2).
