    Abstract:
    OBJECTIVE: The adequate surface conditioning method for GI-II glass infiltrated alumia ceramic was investigated. METHODS: The test specimens were divided into 3 groups (A. HF + silicon, B. sandblasting + silicone and C. thermal silicoating + silicone). Shear bonding strengths of porcelain bonded to dentin were tested. RESULTS: The bond strength of group A and B slightly increased after one day but decreased sharply after 30 days. However, no statistical significance was observed. The group C showed a pronounced enlargement of bond strength after one day and had a durable bond after 30 days' thermal cycling. It is statistically significant when group C was compared with group A and B. CONCLUSION: It can be inferred that silicoating method be a better way for glass infiltrated alumia ceramic bonding.
