Cementation Recommendations
Conventionally cement using resin ionomer cements or bond for maximum retention on non-retentive preparations.
Bonding: Indicated for maximum retention and compressive strength of crowns, veneers, inlays and onlays when tooth preps are primarily supra-gingival and isolation is possible. Use self-cure or dual cure adhesive cements for most restorations. For cosmetic veneers use light cure or dual cure cements with shading options.
Conventional Cementation: Indicated for full coverage crowns only. Use self adhesive resin cements or resin modified glass ionomer in situations where a conventional cement would normally be used, i.e., a retentive prep design, a high-strength restoration with adequate thickness, or a tight fitting crown.
