1. We are going to present our product, Luna-Wing
We are going to present our product, Luna-Wing. Luna-Wing is a light-cured indirect composite resin.

2. What Do You Think This Is?
This dragon is made using Luna-Wing. Since Luna-Wing has excellent workability and enough hardness, we can do such detailed work.

3. Characteristics of Luna-Wing
Easy Handling & Great Workability
Variety of Shade Colors
Low Shrinkage Level
Proven Biocompatibility
Excellent Mechanical Properties
Here are five features we would like to talk about for Luna-Wing. Those features from #1 to #3 are for the dental technicians. For #4 and #5, they are related to patients and doctors.
1.Easy Handling
2.Color Reproduction of Natural Tooth (lots of color variety)
3.Low Shrinkage Level
4.Proven Biocompatibility
5.Excellent Mechanical Characteristic

4. Easy Handling & Great Workability
POINT 1： Primer Paste Viscosity
As Primer Paste has perfect viscosity, it flows into the undercut area of retention beads easily to enhance the adhesive strength mechanically.
Also, with the paste, light curing is secured with a deep light cure depth and this avoids troubles such as removal by occlusion.
We are now explaining about the workability of primer paste for Luna-Wing. When using metal, primer paste is used before applying shade opaque. Primer paste has optimal viscosity, and, as you can see the picture, it flows into the undercut area of retention beads easily and also enhances the adhesive strength mechanically. Also, the whitish translucency of primer paste allows for an effective curing undercut area. The white color also works as a shading for the metal, so that opaque layering can be kept thinner in order to avoid immature curing.

POINT 2 Body Resin
① Dentine Series　（Cervical, Opaque Dentine）
Maintains its form without dripping off during the forming process such as mamelon on dentine layer.
② Enamel Series　（Trans Enamel, Translucent, Effect）
Prevents air bubble formation by having a viscosity 30% less than Dentine series.
We are going to explain about the workability of body resin. There are two kinds of resin; one is called Dentine type such as cervical and opaque dentine, and the other one is Enamel type such as trans enamel, translucent, and effect .
The dentine type is designed to maintain its shape, and it won’t be hanging down and stickiness; therefore, it makes it much easier to reproduce mamelon on dentine layer.
Luna-Wing Enamel, Translucent and Effect are designed to 30% less consistency than body resins such as Dentine, Cervical, and Opaque Dentine. This consistency prevents from entrapping of air and it fills up the space around mamelon easily..

6. Variety of Shade Colors
Effect
Body resin for characterizing
9 colors
Stain
Paste for characterizing（effective color expression with thin layer)
We have a great line-up of nine Effect body resins to characterize colors. Our extensive range of Stain colors comes to a total 21 colors. The three of vivid Stain colors (Blue, Yellow, Red) give you infinite possibilities to create new colors by mixing with other stains.

7. Nanofiller & Nano Technology
Luna-Wing is one of the highest-density filler products on the market by using a mix of different-sized inorganic fillers.

The dentine type is designed to maintain its shape, and it won’t be hanging down and stickiness; therefore, it makes it much easier to reproduce mamelon on dentine layer.
Luna-Wing Enamel, Translucent and Effect are designed to 30% less consistency than body resins such as Dentine, Cervical, and Opaque Dentine. This consistency prevents from entrapping of air and it fills up the space around mamelon easily..

8. Low Shrinkage Level Low High ⇒ High Low High Low
Highly-filled filler makes less curing shrinkage and prevents from cracks and enhances accuracy of matching, especially 3unit bridges.

Curing Shrinkage Rate
The graph shows shrinkage rate. Composite materials shrink while hardening, and shrinkage may cause cracks and deformations. Luna-Wing exhibits only 1.8% shrinkage rate, meaning it is possible to maintain better quality over long periods of time. The higher filling rate, the lower shrinkage rate and incidence rate for crack as well.

9. Mechanical Properties - Bending Strength
Excellent Bend Strength avoids troubles such as cracks and removal in the mouth better than normal resin.
Bend Strength [Mpa]
Weight
Now, I’d like to talk about mechanical characteristics. To measure bending strength, we’ve examined with the machine. As you can see on the right chart, Luna-Wing has better bending strength compared to the other products. It is confirmed that the strength avoids troubles such as cracks and removal in the mouth.

10. Mechanical Properties – Vickers Hardness
Fillers’ particle size is well-adjusted and fillers are formulated with high density and good balance. Especially in the mouth, the degree if abrasion by brushing is decreased and luster is long-lasting.

Now, we would like to talk about Vickers Hardness. Fillers’ particle of Luna-Wing is well-adjusted and fillers are formulated with high density and good balance.
(Left side graph), It is natural teeth, composite resin, and hybrid resin. Luna-Wing is located the highest level in the composite resins which is the same level as hybrid resin. Compared to other products, Luna-Wing has much higher hardness. HV
