Among dental bioceramics, yttria stabilized zirconia (YSZ) is gaining increased use due to its superior mechanical properties and aesthetic concerns [1]. It is available in the market especially for the fabrication of crowns, inlays, dental implant abutments and fixed partial dentures [2]. Clay based minerals, being one of the most common ceramic raw materials, is also used for various medical purposes including antacids, gastrointestinal protectors and drug delivery modifiers [3]. Recent studies revealed that clay minerals are beneficial for osteoblast adhesion, proliferation and osteogenic differentiation [4]. For instance, enhanced osteoblast profileration was reported after the incorporation of montmorillonite in chitosan-poly(glycolic acid) films [4]. In addition, enhanced osteogenic response of preosteoblast cell line MC3T3 was obtained with the addition of laponite in several polymeric matrices including poly(ethylene oxide), poly(ethylene) glycol and GelMA [4]. Therefore, in this study, clay was incorporated in YSZ to enhance its mechanical and biological properties for dental applications.
