Estudo da associação de enxertos e membranas na preservação do rebordo alveolar: uma revisão de literatura

Abstract

Alveolar remodeling starts quickly after extraction, triggering bone loss. This process is due to the fact that the soft tissues have a greater regenerative potential than the bone tissue, making it occupy the place destined for the bone not yet formed. The growing demand for rehabilitation through implants has increased the need for the emergence of techniques to preserve the alveolar ridge, since bone loss makes implant-supported rehabilitation difficult or impossible. The present study aimed, through the literature review, to review the predictability of the use of membranes associated with grafts in the preservation of the alveolar ridge after extractions, when compared to the use of these techniques alone. It was found that the application of membranes and grafts in isolation provides favorable results to the restriction of the natural process of resorption suffered by the dental socket after extraction, however, the isolated performance of the techniques presents limitations that are minimized when they are used in combination. In this way, this study observed a superiority in the results and in the predictability of the strategy of association of these techniques. However, further studies are needed to consolidate the supremacy of the association of membranes and grafts in the process of preservation of the alveolar ridge.
