Clinical Performance of Extended All-Ceramic Fixed Partial Dentures Based on Zircon-Oxide Ceramics.

Clinical Performance of Extended All-Ceramic Fixed Partial Dentures Based on Zircon-Oxide Ceramics

Fixed-partial dentures fabricated of zircon-oxide ceramics were introduced in dentistry some time ago. However, the survival rate of all-ceramic extended (up to 47mm) fixed-partial dentures is unknown.

The hypothesis was that long FDPs fabricated of zirkon-oxide withstand masticatory forces in the posterior and anterior regio of the jaw.

30 patients with at least 2 missing posterior or anterior teeth will be included in the study. All patients will receive all-ceramic fixed partial dentures.

Inclusion Criteria:

• All patients older 18 years
• At least two missing posterior teeth
• Tooth wear<3

Exclusion Criteria:

• Bruxism
• Mental disorders
• Pregnancy
• Tooth mobility>1
