‘boxing in’ refers to
a. method of preserving the outline and functional integrity of primary and definitive casts
b. method of preserving the outline of definitive casts
c. method of preserving the outline of primary casts
d. method of preserving the functional width and depth of the vestibular sulcus using rubber moulds
e. method of preserving the functional width and depth of the vestibular sulcus
e
an arcon articulator may be inidicated for dental prostheses as it is more accurate than a non-arcon articulate as
a. the condylar inclination is at a fixed angle to the maxillary occlusal plane.
b. The hinge axis permits a smaller axis of closure
c. inaccuracies when a protrusive record is being used to determine the articulator settings is reduced.
d. it has the condylar track on the upper part of the articulator
e. the condylar inclination changes as the articulator is open.
d?
where should post dam be cut for maxillary denture
a. Approximately 2mm distal to the palatine fovea on the definitive cast
b. Approximately 2mm in anterior to the palatine fovea on the definitive cast
c. On the soft palate distal to the hard palate to provide compression of the soft tissue
d. On the compressible tissue at the distal of the hard palate indicated by the vibrating line
e. At the junction of the hard and soft palate indicated by the vibrating line on the definitive cast
b
simple hinge articulator can be used for construction of complete dentures
a. as the occlusal vertical dimension can be checked
b. as it can be relied on to reproduce the centric relation position accurately
c. as a split cast mounting can be used
d. as non-working contacts can be checked for balanced articulation
e. using a functional generated path occlusal rim
a or c?
the purpose of the split-cast technique used when mounting casts on an articulator is to check the occlusal vertical dimension following processing of the denture
a. False, as this technique is only used when a facebow has not been used to mount casts
b. True, when casts have locations and the occlusal vertical dimension is recorded
c. . False, since the incisal post indicates the occlusal vertical dimension
d. True when the incisal post is located on the incisal table.
e. True, when casts have appropriate locations grooves cut in the base.
b
when prescribing special trays for complete dentures which statement is the most appropriate
a. Edentulous trays with perforations for complete dentures enable a more through decontamination process.
b. Edentulous trays without perforations for complete dentures enable a more secure retention for the impression material.
c. Edentulous trays with perforations for complete dentures enable a more secure retention for the impression material.
d. Edentulous trays without perforations are stronger that perforated trays.
e. Edentulous trays without perforations for complete dentures assist in estimating a peripheral seal.
e
if the occlusal vertical dimension is reduced by 2mm, what effect might this have for complete dentures
a. It will reduce the free-way space
b. No effect if the teeth used are set in balanced occlusion
c. It will increase the free-way space
d. The resting face height will be increased
e. the resting face height will be decreased
c?
