Abstract(s)
O autotransplante dentário é uma opção de tratamento que visa a reabilitação de um espaço edêntulo através do reposicionamento cirúrgico de um dente extraído (Yang et al., 2018).
Por outro lado, os implantes dentários podem ser descritos, de forma simplista, como estruturas capazes de suportar cargas, às quais serão fixadas coroas artificiais (Buser, 2016; Albrektsson et al., 2019).
A revisão proposta pretende comparar o grau de sucesso relativo destas duas opções de reabilitação em casos de perda unitária de peças dentárias em zona funcional mandibular – 4.º e 6.º sextantes, com o intuito de obter uma recomendação fundamentada para casos clínicos equiparáveis.
A pesquisa foi realizada por dois investigadores de forma independente na base de dados PubMed de janeiro de 2017 a dezembro de 2020. Após uma criteriosa seleção, os dados foram compilados em diversas metanálises que avaliam as taxas de sobrevivência dos tratamentos em diferentes tempos de followup.
Foram identificados 14 artigos que preenchiam os critérios de seleção. As taxas de sobrevivência obtidas não apresentam diferenças estatisticamente significativas entre si (p>0,05). Foi, assim, possível identificar uma taxa de sobrevivência para os autotransplantes dentários de 94,8% a 6 meses, 95,3% a 1 ano, 92,9% a 5 anos e 91,3% a 10 anos. Relativamente aos implantes imediatos, as taxas de sobrevivência foram de
97,4 a 6 meses, 93,4% a 1 ano e de 96,4% a 5 anos, não sendo possível com a amostra incluída obter uma taxa de sobrevivência a 10 anos.
Deste modo, é possível concluir que ambas as opções terapêuticas apresentam uma previsibilidade semelhante e de elevado grau de sobrevivência a longo prazo. Ainda assim, mais estudos são necessários para que se possa compreender a previsibilidade dos tratamentos em tempos de followup maiores.
Aim: The aim of this study is to compare the survival rate of teeth autotransplantation with immediate implant placement in cases of singular loss of teeth and obtain a clinical recommendation for similar cases. Materials and methods: The research was conducted by two independent reviewers in PubMed search. The articles included were from January 2017 to December 2020. Survival rates in different followup times were evaluated and the information was compiled in several metaanalysis. 14 studies were included. There were no significant statistical differences between the samples (p> 0,05) and a comparison was there for possible. Results: Regarding tooth autotransplantation, it was possible to obtain the following survival rates: 94,8% after 6 months, 95,3% after 1 year, 92,9% after 5 years and 91,3% after 10 years. As for the immediate implant placement interventions, a survival rate of 97,4% after 6 months, 93,4% after 1 year and 96,4% after 5 years were obtained. The sample included did not allow for a 10year followup survival rate for the implant placement interventions. Conclusion: Bearing in mind this survival rates, it is possible to conclude that both interventions present a high level of predictability and success at short, medium and long term. Therefore, both interventions can be considered for the unitary rehabilitation of teeth in selected cases.
