A. Stump inlays and metal-ceramic crowns

B. Artificial metal swaged crowns

C. Restoration of tooth crowns with composite materials

D. Fabrication of plastic inlays

E. Richmond's pivot crowns

A. Forming a bevel

B. Forming an additional shoulder

C. Cavity floor widening

D. Preparation for parapulpal posts

E. Cavity deepening

7. A 28-year-old patient consulted a prosthodontist about dental prosthetics. Objectively: crown of the 13 tooth is decayed by 2/3 of its height, the stump sticks out above the gum line by 2 mm.

A. Pivot tooth

B. Crown

C. Inlay

D. Equator crown

E. The crown should be restored with photopolymer

8. Physical examination of a patient revealed a hard tissues defect of the 24 tooth. Index of occlusal surface destruction was 0, 8.

A. Pivot crown

B. Artificial crown

C. Inlay

D. Portion crown

E. Equator crown

9. A 54 year old woman complains about wear of the 35 and 36 teeth and pain caused by thermal and chemical stimuli. Objectively: crowns of the 35 and 36 teeth are worn by 1/3 of their height (horizontal type), the 24, 25 26 teeth have one-piece-cast crowns. What crowns should be made for the 35 and 36 teeth?

A. One-piece-cast crowns

B. Combined crowns by Belkin

C. Metal stamped crown

D. Plastic crown

E. Metal-ceramic crown

10. A 25-year-old patient complains about a cosmetic defect in the frontal part of his upper jaw on the left. Objectively: the 23 tooth is pulpless. The filling restores vestibular-approximal surface of the tooth crown by 1/3, it is stable, closely fits within cavity walls, its colour doesn’t match the colour of the tooth. The tooth itself has changed its colour, its percussion is painless. What is the optimal prosthetic construction for this patient?

A. Metal-ceramic crown

B. Elastic crown

C. Metal swaged crown

D. Portion crown

E. Inlay
