Answer 1

Polychromatic conformative restoration 
Altering morphology (veneering/bonding)
Occlusal rehabilitation
Repairing failed composite and ceramic 
Tooth splinting and temporary bridges

Question 2

What is the restorative composite selection based on?

Answer 2

Shade and opacity
Filler composition
Physical properties
Handling characteristics cost

Question 3

What is the composite classificaion of filtek supreme?

Answer 3

Nanofilled

Zirconia/silica nanofillers and clusters

Question 4

What are the different complexities of composites?

Answer 4

Universal every day
Dual opacity composites
Polychromatic layered composites
Tints, opaquers, intensives and opalescents

Question 5

Universal composite uses/properties?

Answer 5

Everyday use for small cavities

Limited shad sub micron hybrids

Question 6

Dual opacity composites uses/properties?

Answer 6

Provide a range of dentines and enamels in ‘vita classic’ matched shades
Low cost introduction to layered multi-coloured techniques

Question 7

Layered composites - multi-opacity systems uses/properties

Answer 7

Kits are complex and costly
2 or more levels of opacity
intensive and translucent shades 
Training required 
Special instruments used

Question 8

Filtek supreme properties?

Answer 8

4 opacities in 34 vita based shades
Carefully refined shade matching
Mechanical properties of hybrid composites
Outstanding polishability with good retention of surface finish
Excellent handling characteristics
High wear resistance

Question 9

What is Shade assessment using the Vanini method?

Answer 9

1. Base chroma (dentine shades)
2. Value (enamel shades)
3. Intensives (diffuse/opaque white)
4. Opalescents (translucencies)
5. Chaacterisations (halos, cracks, banding)

Question 10

What are different finishing systems?

Answer 10

Fine diamond and TC finishers
Polishing discs
Smoothing and high gloss
Fast gloss polishing

Question 11

Can composite to composite repair be done?

Answer 11

yes, bond strength dependent on adhesive and structure of aged composite
Clinical studies lacking on longevity
Viable option for small fractures and margin failures in large restorations

Question 12

How can Heterogeneous ceramic be repaired?

Answer 12

Heterogeneous ceramics (leucite/feldpathic) can be HF acid etched - creates reliable strong bond with silane coupling and appropriate resins

Question 13

How can low fusing homogenous ceramics alumina and zirconia be repaired?

Answer 13

cannot be bonded

Question 14

How can combined metal ceramic crown repair be carried out?

Answer 14

if in doubt use CoJet silicoating and silane

Highly successful with combined metal and ceramic exposures

Question 15

What composite is used for splinting?

Answer 15

StickTeck fibre reinforcement
