Abstract
Introduction: Autogenous dental transplantation (ADT) is defined as the replacement of a compromised or condemned dental element, usually the third molar being the tooth of choice to be transplanted due to proximity to the region and anatomic similarity, the technique consists of after extracting the affected tooth, a selective extraction of a sound third molar must be performed, which will be destined to the pre-existing alveolus or surgically prepared for the adequacy of the roots. Objective: The objective of this work is to report on the technique of autogenous transplantation performed in lower teeth of the right hemiarch. Case Report: 20-year-old male patient, with no previous medical commitments, attended a private dental office in the city of Belém, northern Brazil, with an indication for extraction of element 46. On clinical examination, it was observed that the coronary structure was damaged by extensive carious lesion. The periapical radiological examination showed the extension of the lesion to the furcation region and because the patient did not have the economic conditions to perform the pulpectomy treatment and subsequent placement of indirect restoration, as well as immediate installation of a dental implant for rehabilitation, therefore, we opted for the extraction. Also during the clinical examination, the presence of partially erupted and healthy element 48 was observed, and the ADT was idealized. In the surgical procedure, the patient received local anesthesia of 4% articaine and 1,100,000 adrenaline with 0.12% chlorhexidine, then the extraction of tooth 48 followed the same minimally traumatic pattern of the anterior element and after complete dislocation it was immediately implanted in the tooth socket and platelet concentrate membranes (L-PRF) and sutured with thread nylon 4.0. Conclusion: From the reported case, we can conclude that ADT, despite being an unusual treatment method, is a promising rehabilitation treatment, due to its economic viability, for being judicious in terms of conservation, biological principles and for providing harmony in the aesthetic-functional aspect.
