Esthetic considerations for reshaping of autotransplanted premolars replacing maxillary central incisors: a case report

Abstract

Autotransplantation is a safe and currently common procedure in cases of agenesis and tooth loss. Autotransplantation of premolars to replace missing maxillary central incisors has been shown to be an excellent treatment choice, especially in young patients in the 9-12-year-old age range. The choice for adequate restorative materials and techniques is also essential, direct composite resin being indicated in most cases. This paper reports the case of two premolars autotransplanted to replace both maxillary central incisors and addresses the esthetic issues involved in the reshaping of these teeth to incisor morphology.

Autotransplantation of teeth to the anterior maxilla: A systematic review of survival and success, aesthetic presentation and patient‐reported outcome

“…A more recent case report confirmed that the biggest clinical challenges when autotransplanting premolars to the anterior maxilla were to create a pleasing colour of the crown and width in the cervical area. 23 The cervical width of the transplants is dependent on the angulation at which the surgeon places the transplanted tooth in the alveolar socket and/or how the orthodontist is able to rotate it postoperatively. This will strongly influence the final mesio-distal width of the transplant.…”

An evaluation of 910 premolars transplanted in the anterior region—A retrospective analysis of survival, success, and complications

“…It is speculated that a rotation of 90° of the transplant during surgery may improve the emergence profile aesthetically. 32 However, this may result in a too wide cervical width and consequently to compromised aesthetics. None of the transplanted premolars in the present retrospective analysis were rotated.…”

Autotransplantation of Immature Third Molars and Orthodontic Treatment After En Bloc Resection of Conventional Ameloblastoma

“…Tooth autotransplantation can also induce alveolar bone growth and re-establish the alveolar process. 25,[28][29][30] The risk of ankylosis after transplantation of an unerupted tooth germ is reduced, because the dental follicle protects the root surface from injury. Additionally, transplantation of unerupted teeth has been associated with a high likelihood of pulp revascularization, generation of normal periodontal tissue, and root growth.…”
