A) the types of veneers are clearly separated groups with no possible variations in betweenB) it is technically not possible to make non-prep veneersC) super thin veneers are technically more difficult than thicker veneers
24. which statement is true?*

A) canine guidance cannot be achieved with an additional veneerB) additional lateral veneers are a suitable method to close proximal gapsC) a vertical silicon key has no advantage
13. Types of Veneers Part 2
25. which statement is false?*

A) feldspathic porcelain is much stronger than lithium(di)silicatesB) feldspathic porcelain is much weaker than lithium(di)silicatesC) clinically the strength of all dental ceramics is reduced about 50% in the first years of use
26. which statement is true?*

A) it is forbidden to make veneers if there is no enamel left at allB) the less enamel is present, the less ideal is the indication for veneersC) thin weak porcelain veneers on dentine-only preparations work as well as any other combinations
14. Preparation for Veneers Part 1
27. which statement is true?*

A) Veneer preparations should never be made under loupe magnificationB) veneer preparations look always exactly the sameC) a veneer preparation means basically a uniform reduction of the anatomy in regard to the later result
28. which statement is true?*

A) all shapes of rotation instruments are equally suited for veneer preparationsB) an isolated area of translucency in a veneer can cause a dark spot in the final result.C) dental ceramics show high resistance against tensile forces and therefore sharp edges on the tooth are clinically irrelevant
15. Preparation for Veneers Part 2
29. which statement is true?*

A) Veneers can also be combined with direct restorationsB) direct restorations should always be included in the veneer preparationC) old direct restorations should not be renewed before combining them with veneers
30. which statement is true?*

A) for closing diastemas the preparation should be extended interproximally as far as possibleB) the proximal preparation when intact neighbor teeth are present is the easiest partC) sonic instruments offer no advantages
16. Veneer Provisionals

17. Adhesive Cementation Part 1
33. which statement is true?*

A) every material and indication can also be conventionally cementedB) excess composite cement is clinically not relevantC) the contamination of bonding surfaces with greases, oils and fats should be avoided at all cost.
