Resin Bonded Fixed Dental Prostheses

Which ceramic restoration requires bonding?

lithium disilicate

How are zirconia restorations retained?

Cohesively / adhesively

What are some cohesive luting cements?

1. Zinc phosphate

2. Polycarboxylate

3. Resin-reinforced GI

4. Resin

How do cohesive luting cements work?

They rely exclusively on retentive form. There is no adhesive interaction between the surfaces

What is the true adhesion between the two joining materials?

Resin

What is the order of the compressive strength of definitive cements from strongest to weakest?

Resin > resin-reinforced GI > zinc phosphate > polycarboxylate

What are some advantages of zinc phosphate?

1. History of use

2. Adequate strength

3. Minimal film thickness

4. Easily remove excessive material

What are some disadvantages of zinc phosphate?

1. Not translucent

2. Solubility

3. Mixing technique sensitivity

What is an indication for zinc phosphate?

Full coverage cast restoration

What are some advantages of polycarboxylate?

1. Relative biocompatibility

2. Adhesion to dentin

What are some disadvantages of polycarboxylate?

1. Not translucent

2. Solubility

3. Low strength

4. High viscosity

What is an indication for polycarboxylate?

Provisional restorations

What are some examples of resin-reinforced GI?

1. RelyX Luting (3M)

2. Fuji Plus (GC)

3. ProTec CEM (Vivadent)

What are some advantages of resin-reinforced GI?

1. Higher strength

2. Clean-up easily

3. Less early moisture susceptible

4. Translucency

What is a disadvantage of resin-reinforced GI?

Expands during setting

It is CONTRAINDICATED to use what kind of cement in all ceramic restorations & post and core?

Resin-reinforced GI

What are some indications for resin-reinforced GI?

1. Casting metal restorations

2. Metal ceramic restorations

3. Zirconia-based all ceramic restorations

What kind of resin does not require bonding protocol?

Self-adhesive resin

For which types of resin must you follow bonding protocol?

Dual-cured resin and light cured resin

What are two types of light cured resin?

1. RelyX Veneer (3M ESPE)

2. Variolink Esthetics LC (ivoclar vivadent)

What are some advantages of light-cured cement?

1. Superior bonding strength

2. Working time

3. Color stability

What are some disadvantages of light-cured cement?

1. Strict bonding protocol

2. Clean up after setting

3. Critical need for light to insure proper cure

What is an indication for light-cured resin?

All ceramic veneers
