5. design of bridge pontics
Bridge pontics are designed with esthetic and functional aspects as well as oral hygiene in mind. The area of the pontic
that contacts the alveolar ridge should be made of ceramic.
In order to ensure adequate stability between the bridge pontic and the bridge abutments, a palatal and/or lingual scallop
is recommended. Furthermore, to ensure even cooling of the bridge pontic that absorbs the most heat, additional
cooling struts are advantageous.
6. Interface between metal and ceramic
The interface between the metal framework and the veneering ceramic must be clearly defined. If possible, incorporate a
right angle finish line. The junctures between the metal framework and the veneering ceramic must not be located in the
contact area nor on surfaces involved in masticatory functions. The interface in the interdental area should be designed in
such a way that cleaning of these hard-to-reach areas is possible.
