Fixed Prosthodontics
- To minimize flexing caused by long and/or thin spans in pontic designs, a rigid connector should be selected.
- The secondary retention (R) should extend from the primary interabutment axis.
- The forces on castings serving as retainers for fixed partial dentures differ from those applied to single restorations in that they are more complex and involve more than one tooth.
- Dislodging forces on a fixed partial denture retainer tend to act in a lateral direction.
- The retainers on secondary abutments will be placed in tension when the pontics flex, especially on distal abutments.
- A common problem in replacing all four maxillary incisors with a fixed partial denture is the lack of adequate support.
- A secondary abutment must meet the criterion of being able to withstand forces without becoming a problem itself.
- The preferred way of fabricating most fixed partial dentures is through casting.
- It would be unwise to use a lateral incisor as a secondary abutment in situations where the tooth is not strong enough to withstand the forces.
- To offset the torque produced when pontics lie outside the interabutment axis line, the retainer should be designed to resist the torque.
