INTRODUÇÃO: em reabilitações de arcadas completas com prótese fixa
implanto-suportada, a utilização de zircónia monolítica parece apresentar
diversas vantagens relacionadas com a função e estética. Contudo, a evidência
científica publicada ainda é reduzida. O objetivo desta investigação foi analisar
a evidência científica publicada sobre estas reabilitações, particularmente ao
nível da taxa de sucesso/sobrevivência e complicações mecânicas e biológicas.
MATERIAIS E MÉTODOS: foi efetuada uma revisão sistemática, com protocolo
registado no PROSPERO. A pesquisa bibliográfica primária foi efetuada na
PubMed® e Web of Science®, e complementada com a bibliografia dos artigos
encontrados. Definiram-se critérios de inclusão e exclusão. Foi seguido o
fluxograma PRISMA para seleção dos artigos. Para avaliação da qualidade dos
estudos utilizaram-se as ferramentas disponibilizadas pela Joana Briggs
Institute. Efetuou-se uma meta-análise realizada para a variável taxa de
sobrevivência (%), aplicando o moderador contínuo específico, período de
acompanhamento dos pacientes. Heterogeneidade dos dados (I2
) avaliada com
Forest Plot e Funnel plot.
RESULTADOS: da pesquisa inicial obtiveram-se 327 referencias. Após
eliminação dos duplicados e aplicação dos critérios de inclusão/exclusão na
leitura dos títulos, resumos e texto integral, incluíram-se para análise 7 artigos.
Todos os artigos incluídos foram do tipo observacional longitudinal retrospetivo,
com um número de próteses efetuadas entre 7 e 2039. A média de idade dos
pacientes reabilitados foi de 60 anos. A posição da prótese variou entre
mandibular, maxilar ou bimaxilar, sempre com retenção aparafusada, com um
número de implantes de 4 a 8. Tempo de follow-up médio: 49,7 meses. A
percentagem de qualidade dos artigos foi superior a 70% e a heterogeneidade
baixa (2=28,64%). A taxa de sobrevivência média foi de 97,23%.
CONCLUSÃO: num prazo médio de aproximadamente 4 anos, as reabilitações
de arcada completa implanto-suportada em zircónia monolítica apresentam uma
taxa de sobrevivência elevada e complicações mínimas.
INTRODUCTION: In full-arch rehabilitation with fixed implant-supported prosthetics, the use of monolithic zirconia seems to have several advantages related to function and esthetics. However, the published scientific evidence is still limited. The aim of this investigation was to review the published scientific evidence on monolithic zirconia restorations, particularly on success/survival rates and mechanical and biological complications. MATERIALS AND METHODS: A systematic review was carried out, with a protocol registered in PROSPERO. The primary literature search was done in PubMed® and Web of Science® and complemented with the bibliography of the searched articles. Inclusion and exclusion criteria were defined. The PRISMA flowchart was followed for article selection. To evaluate the quality of the studies we used the tools provided by Joana Briggs Institute. A meta-analysis was performed for the variable survival rate (%), applying the specific continuous moderator, patients' follow-up period. Data heterogeneity (I2 ) was assessed with Forest Plot and Funnel plot. RESULTS: From the initial search, 327 references were obtained. After eliminating duplicates and applying the inclusion/exclusion criteria by reading the titles, abstracts, and full text, 7 articles were included for analysis. All included articles were observational longitudinal retrospective, with a number of prostheses between 7 and 2039. The mean age of the rehabilitated patients was 60 years. The position of the prosthesis varied between mandibular, maxillary or bimaxillary, always with screw-retained retention, with a number of implants ranged from 4 to 8. Mean follow-up time: 49.7 months. The percentage of article quality was over 70% and heterogeneity was low (I2=28.64%). The average survival rate was 97.23%. CONCLUSION: In a mean follow-up time of approximately 4 years, monolithic zirconia implant-supported full-arch rehabilitations have a high survival rate and minimal complications.
