[Prosthetic dilemmas. Choice of superstructure for the edentulous maxilla].

Patients with an edentulous maxilla can experience problems with a full upper denture. The most common problems are a lack of retention and the stability of the denture, but also other factors, such as an extreme gagging reflex, influence satisfaction. Attachment of a prosthesis on dental implants is a reliable solution to solve or diminish the above mentioned problems. The choice of the kind of superstructure, a removable overdenture or a fixed prosthesis, depends on a variety of factors, such as degree of resorption of the maxilla, cleaning possibilities, patients'wishes and financial possibilities
