Abstract(s)
O objetivo do presente estudo foi realizar uma revisão sistemática da literatura sobre
falhas mecânicas de próteses dentárias híbridas suportadas por implantes. Uma pesquisa de
literatura foi realizada nas bases de dados eletrónicas MEDLINE (PubMed) e b-On, com
trabalhos publicados entre 2011 e 2017. Os seguintes termos foram aplicados nesta pesquisa:
“overdenture attachments”, “abutments“, “Locator”, “fracture”, “stress”, “strain”,
“biomechanics”, “failure”, “FEA” e “full arch dental prosthesis”. A presente pesquisa
bibliográfica resultou em 560 estudos, sendo que 80 foram considerados relevantes tendo em
consideração os tipos de falhas protéticas e os fatores de riscos intrínsecos dos pacientes. Os
estudos selecionados reportaram falhas mecânicas típicas em componentes protéticos, no
entanto há uma variação de condições dos pacientes. Há uma limitação em avaliação do
comportamento biomecânico das próteses e previsão de falhas devido a diversas condições de
tensões oriundas da mastigação, materiais e planejamentos protéticos.

A literature search was conducted on MEDLINE (PubMed) and b-On electronic databases, within papers published between 2011 and 2017. The following terms were used: "overdenture attachments" OR "abutments" OR "Locator" OR "fracture" OR "stress" OR "strain" OR "biomechanics" OR "failure" OR "FEA" AND "full arch dental prosthesis". Bibliographic search resulted in 560 studies although 80 articles were considered relevant regarding the mechanical failures and patient risk conditions. The results revealed typical failures in prosthetic structures although several variables are related to patient conditions. Concerning several different clinical situations, design and materials, here is still a lack of biomechanical studies to predict the long term performance of full arch dental prostheses supported by implants.
