A layer of LiSi Connect is sprayed on the surface of the zirconia bonding surface, and after one sintering, LiSi Connect crystallizes on the surface of the zirconia into a lithium disilicate coating, completing the surface modification of the zirconia. The zirconia treated by LiSi Connect has the same clinical bonding effect as glass ceramics, which helps improve the clinical bonding performance of zirconia.
Easy to dissolve: LiSi 2.0 mixes uniformly in just 20 seconds, doubling efficiency
Fine atomization: 30° Classic Wide-Angle Design. Ultra-Fine Atomization.
Stable color: The color is more vivid and stable, making it easier to identify coating thickness.
Superior adhesion: The bonding strength has increased by 40%. Safe, lasting and effective.
Wide temperature range: Baking window expanded to 40°C, sufficient to withstand furnace temperature fluctuations.
After LiSi connect is sintered on the zirconia surface, the zirconia surface presents a crystal structure similar to that of glass ceram-ics. After acid etching, it forms a rough porous morphology, achieving the effect of surface roughness.
1. Spray a layer of Biomic LiSi connect on the surface of zirconia restoration after its final sintering, and then do the sintering of LiSi connect according to the specified curve.
2. Use 4.5% HF to etch for 90s during acid etching, or use 9.5% HF to etch for 60s.
3. Apply primer containing silane onto the surface of LiSi coating.
4. Use a resin-based cement to complete the bonding of the restoration.

The bond strengths after thermocycling (different cycles at 5‒55℃)
* Spray LiSi 2.0 onto the surface of zirconia, and then sinter; treat with 4.5% hydrofluoric IPS Ceramic Etching Gel (Ivoclar Vivadent, Liechtenstein) for 90 seconds; apply a layer of Monobond Plus coupling agent; use Tetric N-Bond universal adhesive; carry out shear bonding strength test.
* Soak in 5°C water for 20 seconds, then transfer to 55°C water and soak for another 20 seconds.
* Repeat this process for a specific number of times.
