Zirconia-Based Restorations: Literature Review
Journal Title: International Journal of Medical Research Professionals - Year 2017, Vol 3, Issue 2
Abstract
Objective: To review related literature covering different aspects of zirconia-based restoration. Materials and Methods: Electronic search was performed in PubMed, Scopus and Ovid to identify scientific studies that investigated zirconia-based Restorations. The search included all studies published in English language in peer-reviewed journals in the period from 1983 to June, 2015. The search followed a specific strategy which included combination of the following keywords: zirconia, all-ceramic, glass ceramic, fracture resistance, laboratory simulation, aging, crown, FDPs, FPDs, CAD/CAM, fixed partial denture, fixed dental prosthesis, and bridge. Results: Search results with abstracts were transferred into Endnote reference system and duplicates were deleted. Articles were then reviewed at three levels (title, abstract, and full text) to further refine the articles. Conclusions: Yttria stabilized tetragonal zirconia cores veneered with porcelain present a potentially efficient alternative for metal and metal ceramic restorations especially in the posterior region, due to the superior mechanical properties of the zirconia ceramics and the superior esthetic properties of the veneering glass ceramics. The veneering layer is usually applied using the layering technique. Other techniques for the application of the veneering layer include: the overpressing technique and the digital technique. The veneering technique is one of the main factors that can influence the fracture resistance as well as the shade reproducibility of the zirconia-based restoration.
