Proper bonding of glass-ceramic restorations like IPS e.max, sinter-free lithium disilicate, and ZeroFire ceramics is critical to the success and longevity of the restoration. Every step — from cleaning and etching, to silane application, tooth bonding, and final cementation — must be done exactly according to the manufacturer’s instructions for each material used. Shortcuts, forgotten steps, or incorrect assumptions can lead to serious clinical failures.
