A removable partial denture is preferable to a fixed bridge when theedentulous areas are large.abutment teeth are rotated.residual ridges are severely resorbed.abutment teeth are tipped.Question 5 of 20 6. A major connector must beBulkyRigidFlexibleSoftQuestion 6 of 20 7. The path of insertion of RPD is guided byAll undercut areasall of the aboveGuiding planesRetentive areasQuestion 7 of 20 8. When preparing a tooth for either a full-or partial-veneer casting, the functional cusp bevel is an integral part of the occlusal reduction phase. The functional cusp bevel:serves as a positive stop when the casting is seated during cementationprovides space for restorative material of adequate thickness in an area of heavy occlusal contactrelieves the functional cusp from additional stresses when the restoration is loaded in the long axis of the toothenhances resistance form when buccal-to-lingual forces are appliedQuestion 8 of 20 9.
