18. Alteraciones de la masticación en usuarios de prótesis dental removible. Revisión sistemática
Abstract:In aging process, the tooth loss generates the need to use a dental prosthesis. Specific alterations in mastication process of denture-users can be considered a problem not only in relation to the morphofunctional structures modification, but also in personal satisfaction associated to chewing and its functionality. The proposal of this review is to
