Gingival retraction cord is placed for how much minimum time in sulcus?5m10m1m15mQuestion 2 of 20 3. Minimum bone width required for a 4mm implant placement3mm10mm6mm9mmQuestion 3 of 20 4. Which of the following best describes "strain hardening" or "work hardening"?softening a metal at room temperaturesoftening a metal by controlled heating and coolinghardening (or deformation) of a metal at room temperaturehardening (or deformation) of a metal at a very high temperatureQuestion 4 of 20 5. Rests on terminal abutment teeth for a cast metal removable partial denture providesvertical stability.lateral force transmission.primary retention.indirect retention.Question 5 of 20 6. Mandibular movement pattern of complete denture patients and those with natural teeth areMandibular movements are irregular in complete denture patientsMandibular movement is slow in complete denture patientsSameMandibular movement in complete denture patients are completely differentQuestion 6 of 20 7. When performing a functional analysis of occlusion, the mandible may be observed to exhibit a shift from centric relation to centric occlusion in all but one of the following directionsbackward.forward.lateral.upward.Question 7 of 20 8. A surgical template (stent/guide) for an immediate maxillary denture is used toassist in remounting the denture prior to refining the occlusion.indicate areas that require additional hard or soft tissue reduction.control hemorrhage while the new denture is being fabricated.protect the extraction sites while fitting the denture.Question 8 of 20 9. The first ceramic crowns and inlays were made byC. H Land.ThomsonHughesMcleanQuestion 9 of 20 10. 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:relieves 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 appliedprovides space for restorative material of adequate thickness in an area of heavy occlusal contactserves as a positive stop when the casting is seated during cementationQuestion 10 of 20 11.
