Palavras-Chave:Endodontia. Autotransplante. Rizogênese Completa.RESUMO Objetivo: O objetivo da presente revisão da literatura foi verificar as taxas de sucesso, assim como seus fatores predisponentes, do autotransplante dentário em dentes com rizogênese completa. Métodos: Uma busca eletrônica foi executada no PubMed usando MeSH terms e termos livres específicos. Inicialmente, um total de 115 títulos e resumos foram identificados. Um estudo adicional foi identificado como relevante após uma busca das listas de referência. Após a aplicação dos critérios de elegibilidade, apenas 8 artigos foram selecionados. Resultados: De forma geral, os estudos incluídos demonstram elevadas taxas de sucesso, baseado nos parâmetros estabelecidos, como manutenção do ligamento periodontal, cicatrização periapical e saúde periodontal. Além disso, os estudos selecionados na presente revisão apontaram que fatores como os protocolos de extração e reimplante, o tempo de proservação utilizado no estudo e o tempo no qual foi realizado o tratamento endodôntico do elemento transplantado, podem afetar a taxa de sucesso do autotransplante dentário. Conclusão: De acordo com a presente revisão de literatura pode-se concluir que embora ainda existam poucos estudos de autotransplante realizados em pacientes com rizogênese completa, a técnica tem se mostrado uma opção viável e com moderada taxa de sucesso para a substituição de elementos dentários perdidos. ABSTRACT Objective:The objective of the present literature review tis o verify the success rates, as well as the predisposing factors, associated to success rates of dental autotransplant treatments in teeth with complete rhizogenesis. Methods: An electronic search was performed on PubMed database using MeSH terms and free terms. Initially, a total of 115 titles and abstracts. An additional study was identified as relevant after a search of reference lists. After eligibility criteria appliance, only 8 articles were selected. Results: In general, the included studies show high success rates, based on established parameters such as periodontal ligament maintenance, periapical healing and periodontal health. In addition, the selected studies pointed out that factors such as extraction and reimplantation protocols, the time of follow-up used in the study and the time in which the endodontic treatment of the transplanted element was performed, can affect the success rate of dental transplant therapy. Conclusion: According to the present literature review, it can be concluded that although there are still few studies of autotransplantation performed in patients with complete rhizogenesis, the technique has proven itself as a viable option with moderate success rate for replacement of lost dental elements.

Autotransplantation of teeth with complete rhizogenesis: a literature review

“…Autotransplantation of teeth has certain advantages over other methods of restoring missing teeth, such as potential for pulp revascularization, preservation of alveolar bone, no need for preparation of adjacent teeth, ( Plakwicz, Wojtowicz & Czochrowska, 2013 ; Verweij et al, 2017 ) and more cost-effective in China ( Yu et al, 2017 ). However, similar to other countries, autotransplantation of teeth is not very popular in China ( Baviz, 2010 ; Jang, Lee & Kim, 2013 ).…”

“…The success criteria were modified from previous studies and included absence of root resorption and ankylosis, normal periodontal tissue, no deep pockets, and no excessive tooth mobility (horizontal movement >2 mm or any vertical movement) ( Yoshino et al, 2012 ; Shahbazian et al, 2013 ; Yu et al, 2017 ). The survival criterion was that the transplanted tooth was still present at the last visit of the follow-up duration with or without fulfilling the aforementioned modified success criteria ( Shahbazian et al, 2013 ; Yoshino et al, 2012 ).…”

Computer-aided autotransplantation of teeth with 3D printed surgical guides and arch bar: a preliminary experience

Background/AimAutotransplantation of teeth is a method to restore the missing teeth and computer-aided techniques have been applied in this field. The aim of this study was to describe a novel approach for computer-aided autotransplantation of teeth and to preliminarily assess its feasibility, accuracy, and stability.MethodsEight wisdom teeth with complete root formation of eight adult patients were autotransplanted. Individual replicas of donor teeth with local splints, surgical templates, and arch bars were virtually designed and fabricated using three-dimensional printing, these were then applied in the autotransplantation surgeries. Clinical and radiological outcomes were observed, the extra-alveolar time, success rate, and 1-year survival rate were analyzed, and accuracy and stability of this approach were evaluated.ResultsThe extra-alveolar time of donor teeth were less than 3 min. The average follow-up duration was 2.00 ± 1.06 years. All autotransplanted teeth showed normal masticatory function. Ankylosis was found in one patient, and the overall success rate was 87.5%, whereas the 1-year survival rate was 100%. Linear differences between the designed and the immediate autotransplanted positions at crowns and apexes of the donor teeth were 1.43 ± 0.57 and 1.77 ± 0.67 mm, respectively. Linear differences between immediate and the stable positions at crowns and apexes of the donor teeth were 0.66 ± 0.36 and 0.67 ± 0.48 mm, respectively.ConclusionThe present study illustrated the feasibility, clinical satisfied accuracy, and stability of a novel approach for computer-aided autotransplantation of teeth. This new approach facilitated the surgical procedure and might be a viable and predictable method for autotransplantation of teeth.

“…The gingival flap was then replaced over alveolar bone, secured and sutured in place; the donor tooth was stabilized with adjacent teeth using over‐crown sutures or composite splint. Occlusal interference was adjusted; the surgeon could verify that the transplanted teeth were out of occlusion by passing a 40‐mm‐thick articulating paper between teeth without resistance . For cases where donor tooth could fit well in the recipient site, a simple periodontal pack was placed (Figure ), while for cases with large periodontal bone destruction, a wire‐resin splint was recommended for stabilization (Figure ).…”

Objective: To describe a method to fabricate donor tooth replica to assist surgeons in preparation of recipient socket during tooth autotransplantation. Materials and Methods: A total of 28 compromised molars in 27 patients were transplanted with third molars using computer-aided rapid prototyping (CARP) technique. Surgery time and extra-alveolar time were documented. Postoperatively, the distance between cervix of transplanted tooth and the alveolar wall was measured. The degree of postoperative pain experienced was assessed with visual analog scale at day 1, 3, and 7. Results: From 28 clinical cases, the average extra-alveolar time and surgery time were 2.5 minutes (±1.3) and 44 minutes (±6.8), respectively. Postoperatively, the average distance between cervix of transplanted tooth and the alveolar wall was 0.87 mm (±0.15) at the mesial-cervix, 0.95 mm (±0.17) at the distal-cervix, 0.88 mm (±0.18) at the buccal-cervix, and 0.95 mm (±0.13) at the lingual-cervix. The value of visual analog scale score significantly decreased from day 1 to day 3. Conclusions: CARP is a reliable technique for fabrication of tooth like surgical replicas in conventional autotransplantation. Clinical Significance: CARP technique minimized extra-oral time, reduced iatrogenic damage, and consequently increased the survival rate of tooth autotransplantation.
