Question 1

Opposing restoration

Answer 1

like against like. If you have gold on one side, you need gold on other.

Especially an issue with ceramic on tooth. Metal is the best, as it is “kind” to opposing materials

Question 2

If you have a foundation, you need

Answer 2

comparable colors in buildups as the outer material

Question 3

Adjacent teeth have

Answer 3

flouride rich layer - it is thin. If you damage the adjacent

tooth, caries susceptibility will increase due to this lost layer.

Question 4

Transitional line angle

Answer 4

axialocclusal

Question 5

If you have to go subgingival, keep it

Answer 5

2mm above alveolar bone (otherwise, inflammation will occur).

Question 6

Retention form - based on POW.

Answer 6

minimal taper, prep type, luting agent.

Question 7

Partial coverage abutment

Answer 7

Exactly as it sounds - better aesthetics, worse retention.

Question 8

Resistance - premolars

Answer 8

Premolars are easier to do this on than molars (narrower teeth have more resistance).

Question 9

Resistance increases with

Answer 9

taller restorations, lost as taper increases.
