Aesthetic functional area protection concept for prevention of ceramic chipping with zirconia frameworks.

چکیده
Chipping of the ceramic veneer is reported as a frequent occurrence when using zirconia-based fixed dental prostheses (FDPs). One possible cause of this complication is the inadequate support of the veneering ceramic by the zirconia substructure. In this article, early clinical observations from patients treated with 96 zirconia-based ceramic single- and multiple-unit FDPs on natural teeth and implants are presented. The FDPs were fabricated according to the aesthetic functional area protection concept of framework design for the prevention of ceramic chipping.

OBJECTIVES The aim of the present pilot study was to test whether or not posterior zirconia-ceramic fixed dental prostheses (FDPs) with pressed veneering ceramic exhibit less chipping than FDPs with layered veneering ceramics. METHODS Forty patients (13 female, 27 male; mean age 54 years (range 26.1-80.7 years) in need of one maxillary or mandibular three-unit FDP in the second premolar or mo...
متن کاملveneering external layer of the structure. Delamination and chipping of veneering porcelain from the underlying ceramic
CAD/CAM (computer aided design/computer aided manufacturing) processing or zirconia frameworks and overpressing of the veneer are modern methods available to achieve all-ceramic bilayered crowns. Besides materials strength, other factors affect restorations’ clinical longevity, such as prosthesis design and technological steps. The aim of the study is to display alternative modern technologies ...
متن کاملDual-scan technique for the customization of zirconia computer-aided design/computer-aided manufacturing frameworks
The use of bi-layered all-ceramic crowns has continuously grown since the introduction of computer-aided design/computer-aided manufacturing (CAD/CAM) zirconia cores. Unfortunately, despite the outstanding mechanical properties of zirconia, problems related to porcelain cracking or chipping remain. One of the reasons for this is that ceramic copings are usually milled to uniform thicknesses of ...

Background and Aims: The bond strength between veneer ceramics and zirconia frameworks is the weakest component in the layered ceramics. Due to the possible effect of adding pigments to the core materials on the bond strength between core and veneer as well as the introduction of new ceramic materials in dentistry, the aim of this study was to compare the zirconia core-veneer microtensile bond ...
