- Regarding group function occlusion , which is false ?

A – ideally , contacts should be between canines , premolars and the mesiobucccal cusp of the first molar

B – the group function can be seen in patient whose canine were worn away or are missing , thus allowing the posterior teeth to come in contact during lateral movements of the mandible

C- group function occlusion can be seen in class iii malocclusion when anterior teeth are in an edge to edge position or have a reverse horizontal overlap

D – group function is indicated in cases of an anterior open bite , when the alignment of the anterior teeth ( canines ) doesn’t allow disclusion of posterior teeth on the working and non working side

E – group function is not indicated in cases when the crown root ratio of anterior teeth , is significantly increased as in patients with clinical attachment loss

– the gingival margin of the preparation for full crown retainer in posterior abutment with a clinical crown that satisfies the requirements for retention and resistance , should be placed :

– during try in of fixed partial denture , you noticed that the metal frame fits the cast but is short on the abutments the most likely explanation is :

A – air bubbles in the impression of the abutments

B – no retraction cord was placed in the gingival sulcus of the prepared abutments

C- the impression was taken with condensation silicone and was left un-poured for over the weekend

D – the preparation of abutments did not allow common path of insertion

E – the impression was taken with condensation silicone and was poured within 30 min .

� the impact of steep inclination of the eminence on occlusal form of restorations :

A – posterior cusps must be shorter

B – posterior cusps must be taller

C – posterior cusps may be shorter

D – posterior cusps may be taller

E – the most posterior cusp must be longer

– All of the following are advantages of cast post except :

A – custom fit to the root configuration

B – adaptable to large irregularly shaped canals

C – changes in core angulation is possible

D – too much preparation is needed

E – provision of anti rotational properties

- the least type of all ceramic crowns which produces abrasiveness for enamel of opposing and adjacent teeth :

� Regarding smile analysis and specifically for anterior teeth showing in rest and dynamic position ; one of the following statements is FALSE :

A – no show of lower anterior teeth at rest position is favorable

B – minimal show of upper incisor teeth at rest position is favorable

C – show of upper anterior teeth increases with age

D – female show more than male of upper anterior teeth at rest position

E – full length of upper anterior teeth , premolars and interdental papilla are showing during dynamic smile

– regarding effect of determinants on occlusal form of restorations which is false ?

A – the steeper the inclination of the articular eminence the posterior cusp may be taller

B – when medial wall of glenoid fossae allowing more lateral translation , posterior cusps may be taller

C - when horizontal overlap of anterior teeth is increased , posterior cusps must be shorter

D – when vertical overlap of anterior teeth is increased , posterior cusps may be taller

E - anterio posterior curve ( spee curve ) steeper , the most posterior cusps must be shorter

– vita 3 D shade guide , one is false :

A – each shade tab has 3 labels eg 3M1 .

B – A number from 1-5 is showing the value which increases as the number increases

C – the letter M means the hue in addition to R and L

D – the last numeric 1 -3 shows the chroma level that increases incrementally

E – three additional tabs are added to the bleached teeth

– what is not true about functional cusp bevel (FCB) ?

A - lack of ( FCB ) results in thin or perforated cast

B – FCB is wide bevel prepared on palatal inclines of maxillary palatal cusps

C – FCB is Part of retention and resistance preparation design

D – Lack of FCB results in over contoured restoration and deflective occlusal contacts

E – under preparation of axial wall may result from lack of FCB preparation
