Abstract

<abstract abstract-type="main" id="iej12223-abs-0001"> <title>Abstract</title> <sec id="iej12223-sec-0001" sec-type="section"> <title>Aim</title> <p>Autotransplantation is a viable treatment option for a missing tooth when there is a suitable donor, especially in adolescents with remaining facial growth. This report presents the aesthetic restoration of a missing maxillary lateral incisor through orthodontic treatment and autotransplantation of a mesiodens using a CBCT‐fabricated rapid‐prototyping model.</p> </sec> <sec id="iej12223-sec-0002" sec-type="section"> <title>Summary</title> <p>A 14‐year‐old male patient with a congenitally missing maxillary lateral incisor was referred from the Department of Orthodontics. The teeth were moved orthodontically to regain space for the missing lateral incisor and to close the space of the mesiodens after transplantation. A replica of the donor tooth was fabricated from a cone‐beam computed tomography scan through a rapid‐prototyping machine before autotransplantation surgery. The model was used to create a socket for the graft tooth, thereby shortening the extra‐oral time and minimizing the damage to the root surface. After transplantation and orthodontic tooth movement, the mesiodens was finally restored with an aesthetic laminate restoration. Over 3 years, the aesthetics remained excellent, and the transplant functioned normally without any signs or symptoms of root resorption.</p> </sec> <sec id="iej12223-sec-0003" sec-type="section"> <title>Key learning point</title> <p> <list id="iej12223-list-0001" list-type="bullet"> <list-item> <p>Missing anterior teeth may be replaced through a combination of orthodontics, autotransplantation with a rapid‐prototyping model and prosthodontic restoration, in growing patients.</p> </list-item> </list> </p> </sec> </abstract>
