A hygienic multiple-pontic design.
Fixed partial dentures should be designed for function, esthetics, and easy maintenance. The gingivolingual embrasures between multiple adjacent pontics are unnecessary for function and esthetics and create crevices where food, plaque, and calculus can accumulate. These spaces make oral hygiene procedures more difficult for the patient and the dentist to accomplish. A hygienic design for multiple pontics is suggested that eliminates these unnecessary embrasures and still displays an anatomically realistic, cosmetically acceptable facade.
