  • Implant restorations
  • Three-unit bridges up to the second premolar as the terminal abutment

 

Contraindications

  • Signs of severe bruxism and/or clenching
  • Limited occlusal space
  • A history of broken restorations and/or teeth Preparation

 

Adjusting and Polishing

  • Use a fine grit diamond at slow speed with copious amounts of water.
  • Polish with a porcelain polishing wheel and diamond polishing paste.

 

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.
