Advantages and disadvantages of tooth replacement AdvantagesDisadvantagesRestore aesthetics (particularly important for anterior edentulous areas)Loss of tooth tissue (tooth preparation of abutments often requires significant tooth preparation)Restore function (mastication, speech)Pulpal damage (tooth preparation opens dentinaltubules providing a connection between bacteria in the mouth and the pulp. Connectors may be fixed or movable.Span: The length of the alveolar ridge between the natural teeth where the bridge will be placed.Abutment: The tooth or implant that supports and retains a dental prosthesis.Resin bonded bridge: A dental prostheses where the pontic is connected to the surface of natural teeth which are either unprepared or minimally prepared.
The total number of units in a bridge is equal to the number of pontics plus the number of abutment teeth.Saddle: The area on the alveolar ridge which is edentulous where at least one missing tooth is to be reinstated.Connector: Joins the pontic to the retainer or two retainers together. Retainers can be major or minor.Unit: Pontics and abutment teeth are referred to as units.
Contents.Definitions Fixed bridge: A dental prosthesis that is definitively attached to natural teeth and replaces missing teeth.Abutment: The tooth that supports and retains a dental prosthesis.Pontic: The artificial tooth that replaces a missing natural tooth.Retainer: The component attached to the abutment for retention of the prosthesis.
