Zirconia Bonding Pre-Treatment Agent
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 to complete the surface modification of the zirconia. The zirconia treated by LiSi connect has the same clinical bonding effect as glass ceramics, which helps the clinical bonding performance of zirconia.
① LiSi connect will penetrate into zirconia after sintering to produce a strong bonding layer.
② LiSi connect will form an ultra-thin coating of 6-10μm on the surface of zirconia, which will not affect the restoration design and clinical placement.
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 90-120s during acid etching, or use 9.5%HF to etch for 45-60s.
3. Use a resin-based adhesive to complete the bonding of the restoration, also the use of pure light-type resin adhesive can prevent the restoration from darkening.
