Q1:: What does “TWiNY” mean?

Curing Machines and Methods

Q1:: What curing machine do you recommended as best?
Q2:: In general, some composite resins can be cured in a much shorter time with a xenon light-curing machine. Is it possible to cure TWiNY in a shorter time in this way?
Q3:: If the material is light-cured in a vacuum, can its hardness be increased compared with normal light curing?
Q4:: General composite resins need to be heat-cured immediately after the final light curing. On the other hand, why is TWiNY recommended to be heat-cured after shape modification?
Q5:: What heat-curing machine do you recommend as best?
Q6:: For heat curing, is it all right to put material in boiling water or place it in a furnace or a microwave oven, wrapped in tinfoil?
Q7:: According to the instruction manual, when we are heat-curing Inlay, we should remove the Inlay from the plaster model and then heat-cure it. Why should the Inlay be removed from the plaster model first?
Q8:: Is the curing schedule for TWiNY different from other indirect composite resins?
Q9:: How many times can heat curing be done at a maximum?

Shade and Transparency

Q1:: What are the criteria for designing TWiNY’s shades? Compared with other products, how well does TWiNY match with the colors listed in the VITA Classical Shade Guide?
Q2:: Does TWiNY show florescence?
Q3:: Are TWiNY shades compatible with Luna-Wing and ZEO CE LIGHT shades?
Q4:: How different are the transmittance rates of TWiNY and other products?
Q5:: The shade looks rather grey when TWiNY is applied in the same way as Luna-Wing. Is there any solution for this problem?
Q6:: The instructions for selecting Enamel shades for the A shade and D shade of TWiNY are not the same as for Luna-Wing. Why is this?
Q7:: The difference between the Dentine shade of Enamel and Cervical seems small. Enamel and Cervical look similar with Dentine and there is no visible variation in accent when they are applied.
Q8:: To express translucency, I used WE (White Enamel), Enamel (Enamel) and T (Translucent), but the result was that whiteness was emphasized. Even though T-Glass is the most translucent, it was not translucent enough.
Q9:: Which Gum shade should I use to express blood vessels?

Handling and Operability

Q1:: What’s special about TWiNY’s operability?
Q2:: When my metal spatula touches the cured area while I’m applying hybrid resin, black marks appear. Is there any solution for this?
Q3:: During additional layering, lines appear.

Composites Such As Fillers

Q1:: Is agglomerated filler made by agglomerating spherical nano-fillers?
Q2:: Is the filler processed by silane treatment?
Q3:: Is it easy to grind the agglomerated filler?
Q4:: Does TWiNY offer any Glass filler, like other brands do?
Q5:: Doesn’t nano-filler agglomerate?

Physical Property

Q1:: Is it all right to finish the curing process of TWiNY only by light curing?
Q2:: It is indicated that TWiNY has the strongest bending strength in the world. Is it used for jacket bridges?

TWiNY Flow

Q1:: What is TWiNY Flow?
Q2:: What kinds of shade are included in the TWiNY Flow line-up?
Q3:: Are there any cautions we should follow when using TWiNY Flow?

Others

Q1:: About how many years will restoration set inside the mouth last?
Q2:: Resin Air Barrier is not included in the Intro Set or Gum Kit. Should it be used?
Q3:: For bonding a jacket crown in the mouth, is it better to use resin cement material?
