Abstract(s)
As Resinas compostas sofreram modificações através da introdução de matérias bioindutores
na sua matriz, tais como micropartículas de vidro bioativo (BAG). Compósitos que contenham
este tipo de materiais são denominados de resinas iónicas, permitindo uma troca de iões entre
o material restaurador e o tecido dentário. As resinas iónicas são um novo material que combina
as propriedades físicas dos compósitos e características bioativas dos ionómeros de vidro,
nomeadamente a libertação de iões de flúor em maior quantidade que os ionómeros de vidro e
adicionalmente libertam também iões de cálcio e fosfato. Em Odontopediatria estes materiais
possibilitam uma diminuição na execução de tratamentos mais invasivos, graças às suas
características bioativas que podem estimular a produção de tecido e melhorar a qualidade do
tecido remanescente. Com a presente revisão bibliográfica pretende-se abordar a importância
dos materiais restauradores na medicina dentária e a maneira como as suas características têm
sido aprimoradas fazendo face às necessidades atuais, melhorando a estética, mecânica e
biocompatibilidade.
Composite resins have undergone modifications through the introduction of bioinductive materials in their matrix, such as bioactive glass (BAG) microparticles. Composites containing this type of material are called ionic resins, allowing an exchange of ions between the restorative material and dental tissue. Ionic resins are a new material that combines the physical properties of composites and bioactive characteristics of glass ionomers, namely the release of fluoride ions in greater quantities than Glass Ionomer cements and additionally also release calcium and phosphate ions. In Pediatric Dentistry, this allows a decrease in the execution of more invasive treatments, duo to its bioactive characteristics that can stimulate the production of tissue and improve the quality of the remaining tissue. This bibliographic review aims to address the importance of restorative materials in dentistry and the way in which their characteristics have been improved addressing current needs, improving aesthetics, mechanics, and biocompatibility.
