To record the maximum depression of soft palate, it should be recorded with head at what angle to the floor90 degree30 degree60 degreeParalle to the floorQuestion 2 of 20 3. Upon examination of an edentulous patient, it is observed that the tuberosities contact the retromolar pads at the correct occlusal vertical dimension. The treatment of choice is toconstruct new dentures at an increased occlusal vertical dimension to gain the necessary clearance.proceed with construction of the denture and reduce the posterior extension of the mandibular denture to eliminate interferences.reduce the retromolar pads surgically to provide the necessary clearance.reduce the tuberosities surgically to provide the necessary clearance.Question 3 of 20 4. Assuming a maxillary cast is accurately mounted on an articulator, a centric relation record is used torecord the inclination of the condylar guidance.determine the vertical dimension of occlusion.mount the mandibular cast.establish the occlusal plane.Question 4 of 20 5. The disadvantage of a tooth- supported surgical stent in a single anterior implant is:no sufficient space for the drillsdifficult to determine the drilling depthobscure the adjacent anatomical teeth structuresnot stable enoughQuestion 5 of 20 6. A removable partial denture rest should be placed on the lingual surface of a canine rather than on the incisal surface becausethe cingulum of the canine provides a natural recess.less leverage is exerted against the tooth by the rest.the enamel is thicker on the lingual surface.visibility and access are better.Question 6 of 20 7. the most suitable margin for porcelain crown isdepends upon operators choiceshoulder with bevelchamfershoulderQuestion 7 of 20 8.

Which is not true for palatal lift prosthesis in case of completely edentulous?Retention is compromisedIndicated when palate is not displaceablePosition is sequentially correctedThe retentive meshwork or wire loop is extended to cover the anterior two thirds of the length of the soft palate.Question 11 of 20 12. beading of the rigid major connector is done toincrease the retention of RPDimprove the estheticsproduce a positive contact with the tissueincrease the rigidityQuestion 12 of 20 13. multiple clasp has the following characteristicsCan be used in all edentulous situationsAbsemce of reciprocal armTwo circumferential clasps originating in opposite directions from the terminal end of the reciprocal armTwo circumferential clasps originating in same direction from the reciprocal armQuestion 13 of 20 14.

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 20 of 20 Loading...
