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

Not Applicable

Completed

• Conditions: Tooth Loss, Teeth Replaced Using All Ceramic FPDs

• Registration Number: NCT00176189
• Lead Sponsor: Heidelberg University

Brief Summary

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.

Detailed Description

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.
