“…This aggrement with Sonmez et al (16) whose found that significantly different flexural strength of LVU and ENA may be due to the differences in composition of the resin matrix, dimension, and dispersion of the filler particles. This finding disagreement with Abi et al (20) whose found this difference insignificant which may be due to different test methods and samples dimensions.…”

Objective: The objective of this study was intended for evaluation the effect of different surface treatments on microhardness and flexural strength of two types of resin ceramics. Materials and Methods: A total number of 140 samples were used in this study (70 samples for each test). This samples were divided into two equal groups according to materials (Vita Enamic [ENA] and Lava Ultimate [LVU]), then each group was subdivided according surface treatments into five subgroups Gr 1; no surface treatment (control), Gr 2; alumina particles with size (50µm) for sandblasting, Gr 3; alumina particles with size (110µm) for sandblasting, Gr 4; etching by plasma technology, Gr 5; etching by hydrofluoric acid (n=7). Microhardness was measured by using Digital Display Vickers Microhardness Tester and flexure strength by using Universal Testing Machine. Results: The results of this study revealed that; Control group of ENA recorded statistically significant highest microhardness. Control group of LVU recorded statistically significant highest flexure strength. Conclusion: Surface treatment has adverse effect on microhardness and flexure strength of both resin ceramic materials.

“…4%) upon cooling 16) . The actual monoclinic-tetragonal phase transformation exhibits hysteresis, and the transformation temperature upon heating and cooling have been reported to be approximately 1,227 and 927°C, respectively 17,18) . Therefore, thermal annealing of the mZrO2 coated samples above 1,227°C is expected to induce compressive stress by preventing the volume expansion upon cooling at approximately 927°C.…”

Ceramics has become increasingly popular as a dental restorative material because of its superior esthetics, as well as its inertness and biocompatibility. Among dental ceramics, zirconia is used as a dental biomaterial and it is the material of choice in contemporary restorative dentistry. Zirconia ceramics has both clinical popularity and success due to its outstanding mechanical properties and ease of machining in the green stage via computer-aided design and computer-aided manufacturing technology. Zirconia is one of the most promising restorative biomaterial because it has favorable mechanical and chemical properties suitable for medical application. Zirconia ceramics is becoming a prevalent biomaterial in dentistry. Clinical evaluations also indicate a good success rate for zirconia with minimal complications. This article reviews the current literature on dental zirconia with respect to basic properties, biocompatibility, and clinical applications in aesthetic dentistry as single unit crown.
