[Clinical, bacteriological and histological mucosal findings in the regions of bridge pontics]

Clinical, bacteriological and histological findings based on 30 bridges with ceramic and metal members showed that covering large mucosal surfaces need not lead to severe inflammatory changes of the mucosa or papilla. If the intermediate members have to rest on a punctiform or small surface of the alveolar crest on hygienic and tissue-sparing grounds, the use of glazed porcelain or--with certain reservations-- of highly polished metal can be justified when required for phonetic, functional or aesthetic reasons.
