[Pathological and histological changes in the gingival mucosa under the action of denture bases with and without palatal scraping].

Histological examination showed that denture bases with palatal scraping ("Frankfurt Radierung") do not strain the palatal mucosa any more than is the case with any other palate-covering denture. If the irritation produced by the dental replacement is within the tolerance limits of the palatal mucosa, there will be no pathological changes in epithelium and submucosa in the area of the scraping borders. If the load put on the denture exceeds the tolerance level of the palatal mucosa, so that a denture stomatopathy is resulting, the changes observable in the entire palatal mucosa are also found in the areas where the scrapinb borders are located.
