4/11: Alternative Matrices; Intro to Alternative Resin Restorative Options; Finishing and polishing composites reviews

Question 1

What are examples of sectional matrixs?

Answer 1

1. Original palodent system
2. Palodent plus system

Question 2

What is the original palodent system?

Answer 2

Three different choices of concave-convex bands , to
be held in place by one of the ring clamps

Question 3

When is palodent most useful?

Answer 3

with small composite preparations like this one than with amalgam
- Select a band of the appropriate size, and slip it between the teeth far enough apically to close the gingival margin

Question 4

When should the ring be placed in OG palodent?

Answer 4

AFTER the palodent band

Question 5

Where is the concave area face in OG palodent?

Answer 5

The box

Question 6

What does clamping the palodent cause?

Answer 6

slight separation of the teeth, and assist in getting a better contact on the restoration

Question 7

What is a big drawback of original palodent?

Answer 7

DOESN’T ALLOW WEDGING

Question 8

What do all sectional matrices require?

Answer 8

A rubber dam for safety, in case a ring breaks or flies off

Question 9

What is the palodent plus system?

Answer 9

Another SECTIONAL MATRIX system, Palodent Plus
has four choices of band and two choices of ring
clamp

Question 10

What does the palodent plus system provide a set of?

Answer 10

pinned pliers that engage holes in the band, for use in manipulating the band, both at placement time and when removing it

Question 11

When is a wedge placed in palodent plus?

Answer 11

Before the ring clamp is seated
Note the triangular notches in the plastic tines of the ring, and how they fit down over the wedge in place

Question 12

Describe the automatrix system installation

Answer 12

Question 13

Describe the automatrix system removal after amalgam placement

Answer 13

Question 14

What are limitations to the automatrix system?

Answer 14

1. Must be held in place by your non- dominant hand when there are no undercuts on the side walls of the tooth (as when tooth has been prepared for a
   crown).
2. Doesn’t work well when tooth defects go far apically

Question 15

What is resin infiltration (ICON) treatment for?

Answer 15

Initial (incipient) caries

Question 16

What are initial (incipient) caries?

Answer 16

• Mild fluorosis
• White and brown spot lesions (Following ortho treatment)
• Class II

Question 17

Where can resin infiltration penetrate into?

Answer 17

Outer third of dentin (D1)
“micro invasive”

Question 18

Describe resin infiltration on a class II

Answer 18

Question 19

Describe the steps of resin infiltration on a class II

Answer 19

1 - tooth separation
- with a wedge
- make room in interproximal area for icon applicator
2 - get access to the lesion surface
- icon etch is a 15% hydrochloric gel
- etch takes 120 sec, then rinse
3 - dry in and out
- icon dry is a solution of ethanol
- apply for 30 sec then air dry

Question 20

What is the occlusal surface shaped with when finishing?

Answer 20

round or oval carbide finishing bur or similarly shaped finishing diamond

Question 21

When is polishing accomplished?

Answer 21

with appropriate polishing cups, points, or both after the occlusion is adjusted as
necessary

Question 22

What instruments should you use to smooth prior to light curing?

Answer 22

Plastic instruments
- To place and smooth composite on
occlusal surface
Optrasculpt
- To develop anatomy in composite resin prior
to light curing

Question 23

What is the hollenback carver used for?

Answer 23

Anatomy
Amalgam

Question 24

What do polishing points, cups, and discs do?

Answer 24

Enhance Polishing
* Impregnated with polishing paste
