Addmate

Problem / Question

What kind of shade does Addmate have?

Solution / Answer

The shade of each of the 7 Addmate porcelains is most similar to the EX-3 porcelain listed below.

Problem / Question

Sometimes I get whiteness and sometimes I get blackness baking Addmate. What is the cause of this?

Solution / Answer

The following table shows the causes.

1. Other manufacturers liquid or EX-3 Forming Liquid was used. Black, White
2. Other manufacturers separator or Noritake Porcelain Separator Black, White
3. Contamination from the tissue paper fiber or dust Black
4. The porcelain was kept too long on the pallete White
5. Contamination of the porcelain furnace Black*
6. Contamination from firing pegs Black*
7. Contamination from hand cream and cosmetics Black
8. Iron oxide formation from mixing spatula Black
9. Under-baking. White
10. Using a dryer to remove moisture White
*To clean the furnace (baking tray), run the following baking program

700°C-1040°C with 50°C/min. heat rate, no vacuum, 4 min. hold time
1292°C-1904°C with 122°C/min. heat rate, no vacuum, 4 min. hold time

Problem / Question

Addmate became whitish. Can I repair it by baking it again?

Solution / Answer

No. You need to remove it and then apply it again after determining the cause.

Problem / Question

What kind of cracks can be repaired with Addmate?

Solution / Answer

See the following table.
Impossible
Crack from the opaque separation*1
Cracks from too much compressive stress*1
Possible
Tensile Stress Cracks.*2
Cracks from Impact (for example, the crown was dropped)
Cracks from local intensive heat (heat created by grinding too hard).
Cracks form flux contamination.

*1 Cracks along the framework (the crack does not disappear with water)
*2 Cracks that are not related to the framework shape (The crack disappears when wetted with water.) However, there is the possibility that a new crack will form in another place.

Baking Program for mending Cracks with Addmate:

Dry Out Time 5min. 450°C-°- °

Problem / Question

I want to repair cracks with Addmate after post-soldering.

Solution / Answer

Y°C-920°C to mend cracks, so you need to stabilize the bridge with soldering investment.

Problem / Question

Is it possible to bake Addmate after the crown has been cemented temporarily in the mouth?

Solution / Answer

No, it isn't after 1 month. If it is within 1 month, you can use Addmate after ultrasonic cleaning with detergent and water.

Problem / Question

How can I try to bake before using Addmate?

Solution / Answer

Apply a small amount of Addmate on old used crown and bake it following the schedule IV. If there is no shine at 700°C (1292°F), raise the temperature in increments of 10°C (20°F) each. If, for example, surface is not glossy at 710°C, but is glossy at 720°C (1328°F), this means that the actual temperature is 700°C when the furnace reads 720?�C. In this case, raise all baking temperature settings and vacuum release temperature settings by 20°C (68°C) more. On the other hand, if the surface is too glossy at 700°C (1292°F), lower the temperature in 10°C (20°F) increments until the surface has a slight luster.

Problem / Question

I tried to repair a round house bridge with Addmate, but it did not come out well.

Solution / Answer

Problem / Question

When repairing after a post-solder (Schedule II) when do I use a Hold Time of 1 minute and when do I use 2 minutes.

Solution / Answer

The standard procedure is:
For single crown to 3-unit bridge (not stabilized with soldering investment) -Use 1 minute Hold Time. For 4 or more units or if stabilized with soldering investment -Use 2 minutes Hold Time

Problem / Question

Can I use Addmate for any kind of porcelain?

Solution / Answer

Yes. You can use it with any kind of porcelain except castable ceramics and porcelain for titanium. It is suitable for use with porcelain having a CTE in the range 11.0 -13.0*10-6[°C]-1.

Problem / Question

Can I make porcelain fused to metal by using only Addmate porcelain?

Solution / Answer

No. You cannot match the shade and you cannot get enough strength.

Problem / Question

Can I fuse Addmate to a Gold crown?

Solution / Answer

No, because the thermal expansion coefficient is totally different.
Manabu: I do not understand this question. Does this mean that if I get a pin-hole on a yellow ceramic alloy PFM crown, then I should not use Addmate to repair it?

Problem / Question

Can I do post-soldering after baking Addmate?

Solution / Answer

It is risky. You might get bubbles because the baking temperature of Addmate is lower than temperature of post-soldering. If you need to this kind of repair, first grind off the Addmate, then repair the parts with EX-3 as desired, then post-solder the case, then make additional porcelain repairs with Addmate as desired.

Problem / Question

Can I bake Addmate on the surface after baking stain?

Solution / Answer

Yes. If the stain is NOT too thick.

Problem / Question

Can I bake stain on the surface after baking Addmate?

Solution / Answer

No, because the baking temperature of Addmate is lower than the temperature of stain.

Problem / Question

I want to adjust shade color of Addmate?

Solution / Answer

You need to mix and compound with super stain for it.

Problem / Question

When I try to add Addmate, it does not fuse to the porcelain surface well.

Solution / Answer

Sandblast gently with alumna and clean the place to be applied. Do not dry the Addmate too quickly at the muffle. Avoid under-baking.

Problem / Question

What kind of solder is good for avoiding distortion during a baking program with a High Temp of 660°C (1220°F) and a Hold Time of 2 minutes for repairing a post-soldered case?

Solution / Answer

Use a post-solder whose melting point is higher than 700°C(1292°F). Test it by yourself before using it.

Problem / Question

Can I change the jar to other smaller jar to store Addmate?

Solution / Answer

No. Keep it in the glass jar for quality control purposes.
