    PURPOSE. The purpose of this study was to evaluate the efficacy of two different metal conditioners for nonprecious
    metal alloys for the bonding of porcelain to a cobalt-chromium (Co-Cr) alloy. MATERIALS AND
    METHODS. Disk-shaped specimens (2.5×10.0 mm) were cast with Co-Cr alloy and used as adherend materials.
    The bonding surfaces were polished with a 600-grid silicon carbide paper and airborne-particle abraded using
    110 µm alumina particles. Bonding specimens were fabricated by applying and firing either of the metal
    conditioners on the airborne-particle abraded surface, followed by firing porcelain into 5 mm in diameter and 3
    mm in height. Specimens without metal conditioner were also fabricated. Shear bond strength for each group
    (n=8) were measured and compared (α=.05). Sectional view of bonding interface was observed by SEM. EDS
    analysis was performed to determine the chemical elements of metal conditioners and to determine the failure
    modes after shear test. RESULTS. There were significant differences among three groups, and two metal
    conditioner-applied groups showed significantly higher values compared to the non-metal conditioner group.
    The SEM observation of the sectional view at bonding interface revealed loose contact at porcelain-alloy surface
    for non-metal conditioner group, however, close contact at both alloy-metal conditioner and metal conditionerporcelain
    interfaces for both metal conditioner-applied groups. All the specimens showed mixed failures. EDS
    analysis showed that one metal conditioner was Si-based material, and another was Ti-based material. Si-based
    metal conditioner showed higher bond strengths compared to the Ti-based metal conditioner, but exhibited more
    porous failure surface failure. CONCLUSION. Based on the results of this study, it can be stated that the
    application of metal conditioner is recommended for the bonding of porcelain to cobalt-chromium alloys.

    日常の歯科臨床において「接着」という言葉が定着してきた。歯科治療において接着技法を駆使することは,歯牙の切削量を最小限にし,健全歯質をできるだけ保存することにもつながり,ひいては歯牙の寿命を延ばすことに貢献することとなる。しかし,臨床の現場では手技の浸透が不十分なことがあり,失敗例も耳にする。本講座では,日常の臨床に役立ててもらうを目的に,歯質,および,歯冠修復物との接着に関して基礎と臨床について解説を行った。
