3. Characteristics of Luna-Wing • Easy Handling & Great Workability • Variety of Shade Colors • Low Shrinkage Level • Proven Biocompatibility • Excellent Mechanical Properties

4. Excellent flowing into undercut Paste Paste Retention Beads Pic.2 Primer Paste After Light Curing Pic.1 After Applying Primer Paste 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.

5. Mamelon Pic.1 ①Reproducing mamelon 　　　　　（Using Dentine A3） Easy Handling & Great Workability 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. Preventing air bubble formation Pic.2 ②After forming enamel layer 　　　　　（Using Translucent）

6. Variety of Shade Colors Effect Body resin for characterizing 9 colors Stain Paste for characterizing（effective color expression with thin layer) 21 colors Mixing Blue・Yellow・Red allows color adjustment 3 colors + Black 3 colors 3 colors + White

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. • Extremely Low Shrinkage - Only 1.8% • Bending Strength • Hardness • Other Properties

8. Low Shrinkage Level Highly-filled filler makes less curing shrinkage and prevents from cracks and enhances accuracy of matching, especially 3unit bridges. Curing 3 unit bridge Curing Shrinkage Rate = set off cracks Stress Pic.1 Points where cracks easily occur Luna Wing B A Luna Wing C Low High ⇒ Filling Rate Fig. 1 Curing Shrinkage Rate of Luna Wing High Low Shrinkage Incidence rate for crack High Low

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 Test Piece25×2×2 Compression stress Tensile stress Luna Wing Luna Wing Pic.1 Examination method is compliant with JIST6517.

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.
