How Supplied

Syringes or single-use cartridge

Composition

Composite resin and silica

Armamentarium

• Composite
• Etchant
• Bonding system
• Curing light
• Restorative instruments
• Composite placement instrument

Directions

1. Etch tooth surface with 37% orthophosphoric acid.
2. Rinse lightly and dry.
3. Prepare etched tooth surface with primer and bonding agent.
4. Place composite material in desired location and shape with composite placement instrument.
5. Polymerize with curing light.
6. Adjust and finish material.

 

image Special Notes/Helpful Hints • A clinician is unable to identify by sight if a composite is macrofilled without the use of a microscope. • Macrofilled composites have large filler particles, which result in a restoration that feels rough to a dental explorer and can appear rough to the eye. The likelihood of plaque accumulation and stain is greater. • This material is used most frequently by orthodontists to bond brackets or other orthodontic appliances.

How Supplied

Syringes or single-use cartridge

Composition

Composite resin and finely ground silica

Armamentarium

• Composite
• Etchant
• Bonding system
• Curing light
• Restorative instruments
• Composite placement instrument

Directions

1. Etch tooth surface with 37% orthophosphoric acid.
2. Rinse lightly and dry.
3. Prepare etched tooth surface with primer and bonding agent.
4. Place composite material in desired location and shape with composite placement instrument.
5. Polymerize with curing light.
6. Adjust and finish material.

 

image Special Notes/Helpful Hints • A clinician is unable to identify by sight if a composite is microfilled without the use of a microscope. • Microfilled composites have small filler particles, which results in a low modulus of elasticity. • Because of their high luster, microfilled composites are most frequently used for class V restorations or as the top layer on an anterior restoration. • Microfilled composites can be polished to a high luster to look like enamel.

MATERIAL

Hybrid Composite

How Supplied

Syringes or single-use cartridge

Composition

Composite resin and silica (composition is a combination of microparticles and macroparticles)

Armamentarium

• Composite
• Etchant
• Bonding system
• Curing light
• Restorative instruments
• Composite placement instrument

Directions

1. Etch tooth surface with 37% orthophosphoric acid.
2. Rinse lightly and dry.
3. Prepare etched tooth surface with primer and bonding agent.
4. Place composite material in desired location and shape with plastic instrument.
5. Polymerize with curing light.
6. Adjust and finish material.

 

image Special Notes/Helpful Hints • Hybrid composites have different-sized filler particles, which result in a strong material that polishes well. • A clinician is unable to identify by sight if a composite is a hybrid composite without the use of a microscope. • Because of their strength and abrasion resistance, hybrid composites are acceptable for class I and II restorations.
