“…For resin-based materials with low modulus of elasticity a recent clinical study found high numbers of debonding between resin nano ceramic crowns and zirconia abutments, which were supposed to be a result of stress concentrations in the adhesive layer [22]. In the present study, LiS, the material with the highest flexural strength and modulus of elasticity, showed the highest fracture resistance, which can be confirmed by the results of previous studies [3,23]. Higher flexural strength of crystallized ZLS (370 MPa) compared to polished ZLS (210 MPa) was reflected in higher fracture forces in two situations (CHAIR, TOOTH).…”

“…Full-contour polished or glazed zirconia FDPs might be an alternative to veneered restorations because of their high resistance to failure and fracture. Zesewitz et al [40] used single monolithic zirconia crown (MZC), monolithic lithium disilicate and monolithic feldspar ceramic in their study. Monolithic zirconia showed the highest fracture resistance of all the samples studied under axial loading.…”

Zirconia restorations have been used successfully for years in dentistry owing to their biocompatibility and good mechanical properties. Because of their lack of translucency, zirconia cores are generally veneered with porcelain, which makes restorations weaker due to failure of the adhesion between the two materials. In recent years, all-ceramic zirconia restorations have been introduced in the dental sector with the intent to solve this problem. Besides the elimination of chipping, the reduced occlusal space requirement seems to be a clear advantage of monolithic zirconia restorations. However, scientific evidence is needed to recommend this relatively new application for clinical use. This mini-review discusses the current scientific literature on monolithic zirconia restorations. The results of in vitro studies suggested that monolithic zirconia may be the best choice for posterior fixed partial dentures in the presence of high occlusal loads and minimal occlusal restoration space. The results should be supported with much more in vitro and particularly in vivo studies to obtain a final conclusion.

“…The use of translucent zirconia could make it possible to fabricate very strong crowns or fixed dental prostheses using zirconia alone, with no need for a layer of porcelain. It has been reported that full contour zirconia crowns fabricated using such a translucent zirconia are more resistant to fracture than full contour glass ceramic crowns 5,6) and produce less wear on the opposing dentition 7,8) . Most of the zirconia materials currently used in dentistry are partially-stabilized zirconia containing yttria (Y-TZP).…”

The purpose of this study was to examine the translucency and low-temperature degradation of silica-doped experimental Y-TZP (Yttria-stabilized tetragonal zirconia polycrystal) containing almost no alumina. The experimental Y-TZP samples were sintered at either 1,450 or 1,500°C. The samples of commercially available translucent Y-TZP and conventional Y-TZP were used as controls. The contrast ratio (CR) and translucency parameter (TP) were obtained to compare the translucencies. In addition, the specimens were also subjected to an accelerated aging test. The results showed that the experimental Y-TZP sintered at 1,500°C and translucent Y-TZP exhibited almost the same level of translucency. During the accelerated aging test, the translucent Y-TZP underwent a substantial increase in monoclinic content, an index of degradation after the aging test. However, neither the experimental Y-TZP nor the conventional Y-TZP exhibited any appreciable change. It was concluded that the silica-doped Y-TZP will develop translucency and resistance to degradation when sintered at 1,500°C.
