Abstract(s)
Introdução: A regeneração óssea guiada é o método de aumento ósseo melhor documentado e
veio tornar possível a colocação implantes em zonas em que existia uma quantidade de osso
insuficiente para o correto posicionamento dos implantes, necessitando para isso de membranas
de barreira para se restabelecer o volume ósseo ideal da crista alveolar.
Objectivos: Comparar os dois grandes grupos de membranas utilizadas em regeneração óssea
guiada, membranas absorvíveis e não-absorvíveis.
Materiais e Métodos: Foi realizada uma revisão narrativa da literatura, nos motores de busca
PubMed e B-On. As palavras chave usadas foram as seguintes: “guided bone regeneration”,
“membranes”, “bone argumentation”, “implants”, “PTFE-e” e “collagen”.
Resultados: As membranas devem garantir um bom selamento, permitindo apenas que células
ósseas e nutrientes cheguem ao local a regenerar. As membranas devem ser escolhidas de acordo
com o tipo de defeito ósseo presente.
Conclusão: A regeneração óssea guiada quando os materiais e a técnica são corretamente
selecionadas, tem uma grande taxa de sucesso e restabelece a arquitetura óssea suficiente para o
correto posicionamento dos implantes endo-ósseos. Para regeneração óssea horizontal a maioria
das vezes é utilizado membranas reabsorvíeis de colagénio.
Introduction: Guided bone regeneration is the best documented method of bone augmentation and has made it possible to place implants in areas where there was an insufficient amount of bone for the correct positioning of the implants, requiring barrier membranes to restore the ideal bone volume of the alveolar crest. Objective: Compare the two large groups of membranes used in guided bone regeneration, absorbable and non-absorbable membranes. Materials and Method: A narrative review of the literature was carried out on the PubMed search engines and B-On. The keywords used were as follows: “guided bone regeneration”, “membranes”, “bone argumentation”, “horizontal guided bone regeneration”, “dental implants”, “PTFE-e” and “collagen”. Results: The membranes must ensure a good seal, allowing only bone cells and nutrients to reach the place to regenerate. The membranes must be chosen according to the type of bone defect present. Conclusion: Guided bone regeneration when the materials and technique are correctly selected, has a high success rate and restores sufficient bone architecture for the correct positioning of the endo-bone implants. For horizontal bone regeneration most of the time, resorbable collagen membranes are used.
