Restoration of Maxillary Anterior Esthetics using Lava All-ceramic Fixed Dental Prostheses

Madan, Nishtha / Pannu, Karneev

Pages: 47 - 53

The success of all-ceramic crowns and increased patient demand for metal-free, tooth-colored restorations has led to the development of many different restorative systems for all-ceramic fixed dental prostheses (FDPs). The most recent core materials for all-ceramic FDPs are the yttrium-tetragonal zirconia polycrystal (Y-TZP)-based materials. Yttrium oxide is a stabilizing oxide added to pure zirconia to stabilize it at room temperature and to generate a multiphase material known as partially stabilized zirconia. This exhibits very high flexural strength and fracture toughness along with good biocompatibility and excellent esthetics. This clinical report describes the use of the Lava All-ceramic system, based on Y-TZP, for the fabrication of two fixed dental prostheses (FDPs) in the maxillary anterior region of the patient, restoring both esthetics and function.

Keywords: all-ceramics, esthetics, crowns, fixed dental prostheses, CAD/CAM technology, zirconia
