Bonding a veneered zirconia anterior fixed partial denture

Area of Science:

• Dental Materials Science
• Prosthodontics

Background:

• Veneered zirconia restorations are increasingly used in prosthodontics due to their favorable mechanical and esthetic properties.
• Fabrication of a three-unit zirconia fixed partial denture (FPD) with porcelain veneering requires specific bonding protocols.

Observation:

• The intaglio surface of the zirconia FPD was prepared using aluminum oxide abrasion and coated with a 10-methacryloxydecyl dihydrogen phosphate (MDP) primer.
• Abutment preparations were treated with phosphoric acid, followed by self-etch adhesive application and light-curing.
• The FPD was cemented using a resin cement, with immediate excess removal and spot-curing of margins.

Findings:

• The described procedure for bonding veneered zirconia restorations is effective.
• The case demonstrates acceptable esthetic and mechanical outcomes for an anterior FPD.

Implications:

• This bonding technique provides a reliable method for integrating veneered zirconia restorations into clinical practice.
• Properly designed and bonded, these restorations can meet the demands of anterior fixed prosthodontics.
