The occlusion rehabilitation in an implant patient differs from natural teeth occlusion, even in a normal occlusion patient, because:limited crown height spaceimplant angulationbone Resorptionimplant- bone relationQuestion 7 of 20 8. Which of the following best describes the term "quenching"?a metal is elevated to a temperature above room temperature and held there for a length of timesoftening a metal by controlled heating and coolinga metal is rapidly cooled from an elevated temperature to room temperature or belowNone of the aboveQuestion 8 of 20 9. Retention from rugae is a type ofindirect retention.Stress breakerDirect retentionStress equalizerQuestion 9 of 20 10. RPI clasp in a distal extension cast partial dentureProvides push type retentionIs contraindicatedProvides pull type retentionUsed for buccally tilted molarQuestion 10 of 20 11. Maximum intercuspation on a complete denture should be established to correspond with centric relation becausechewing occurs in centric relation.it makes it easier to set up the teeth.centric relation is a good reference position.it prevents cheek biting.Question 11 of 20 12.

Dicor porcelain should be subjected. To11 hour firing sequence14 hour firing sequence8 hour firing sequence5 hour firing sequenceQuestion 15 of 20 16. A patient with complete dentures complains of clicking. The most common causes areuse of too large a posterior tooth and too little horizontal overlap.improper relation of teeth to the ridge and excessive anterior vertical overlap.excessive vertical dimension and poor retention.reduced vertical dimension and improperly balanced occlusion.Question 16 of 20 17. Assuming a maxillary cast is accurately mounted on an articulator, a centric relation record is used todetermine the vertical dimension of occlusion.mount the mandibular cast.record the inclination of the condylar guidance.establish the occlusal plane.Question 17 of 20 18. A dental laboratory has fabricated a removable partial denture framework. The framework fits the master cast well but when tried in the mouth a stable fit cannot be achieved. The most likely cause isshrinkage of the alloy during casting.distortion in the final impression.improper casting temperature.improper major connector design.Question 18 of 20 19.
