The effectiveness of the indirect retainer will be more when the distance between the fulcrum line and the indirect retainer isno effectmoreaverageLessQuestion 10 of 20 11. 2 months after wearing a newly formed mandibular denture, patient returns with complaint of redness and erythema on the lingual side of the alveolar ridge from canine to canine. The denture fitting seems good.What will you do?Fabricate a new dentureRemounting and occlusal equilibrationShorten the lingual flangeRelining the dentureQuestion 11 of 20 12. it is better to reduce any occlusal deformities in the existing dentition before the fabrication of a FPD asto maintain a more accurate anatomical occlusal surface in the new restorationto prevent trauma to rest of the dentitionto decrease the amount of adjustment required at the post insertion phaseto prevent the duplication of the deflective occlusal contact in the new restorationQuestion 12 of 20 13. What can be done to increase resistance of an excessively tapered preparationUse a higher adhesive cementAdd goooves along the long axis of preparationIncrease reduction at gingival margin margin to reduce taperReduce height of preparation to shorten are rotation of crownQuestion 13 of 20 14. In kennedy classification, the most common arch isClass-IIClass-IIIClass-IClass-IVQuestion 14 of 20 15. In the double cord techniqueThe thinner cord is inserted first and is removed prior to impression makingThe thicker cord is inserted first and is removed after impression makingThe thinner cord is inserted first and is removed after impression makingThe thicker cord is inserted first and is removed prior to impression makingQuestion 15 of 20 16. 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:provides 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 toothserves as a positive stop when the casting is seated during cementationenhances resistance form when buccal-to-lingual forces are appliedQuestion 16 of 20 17.
