“…[24À35] For example, in a study by Sabrah et al, [24] polished zirconia was shown to cause the least wear on synthetic hydroxyapatite in a two-body rotating pin-on-disk wear test as compared to glazed and as-machined zirconia (1.3, 2.7 and 2.7 mm 3 , respectively). Janyavula et al [25] 3 at 200,000 and 400,000 cycles, respectively).…”

“…Over the last five years, most in vitro studies have focused mainly on the effect of surface treatment on the wear of the material itself and/or antagonists,[24À35] surface roughness, [24,25,27,34,36À38] fracture resistance, [35,39À45] flexural strength, [23,44,46] chipping resistance, [23] compressive strength, [44] elastic modulus, [44] hardness, [33] laser transmission, [47] LTD [48] and CTE-generated stress fields in monolithic zirconia, [49] translucency and colour (Table 1). [35,46,50À56] Although the results from in vitro studies may not fully reflect the clinical performance of the materials due to the complexity of the clinical environment, they have still contributed to the accumulation of a growing body of useful information on the performance of monolithic zirconia.…”

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.

“…In their studies, fine polishing with 10-μm SiC polishing papers or using diamond rubber burrs with 106-125-and 20-30-μm grain sizes did effectively reduce enamel abrasion. Many other studies also verified that finely polished zirconia will not induce excessive abrasion of natural teeth and even provide better protection than other dental ceramics having different surface treatments [102][103][104][105][106]. A 1-year follow-up study revealed that polished full-contour zirconia crowns led to less wear of antagonist enamel, 42.10 ± 4.30 μm for premolar and 127.00 ± 5.03 μm for molar, than porcelainfused-metal crowns, which were 69.20 ± 4.10 μm for premolar and 179.70 ± 8.09 μm for molar.…”

Because of their outstanding mechanical properties, chemical stability, and biocompatibility, 3-mol % yttria-stabilised tetragonal zirconia polycrystals (3Y-TZP), known as zirconia ceramics in dentistry, are an important choice for various types of prosthesis. In addition to extensive use for crown and bridge construction, considerable interest has been generated for applications in implant dentistry, including full-contour zirconia crowns as supra-constructions, zirconia abutments, and novel zirconia implants. However, their use among dentist and researchers is controversial, especially compared with the well-established implants made of titanium alloys. As a latecomer, the merits and limitations of 3Y-TZP are awaiting careful investigation. Design, manufacturing, and clinical operation guidelines are urgently needed. The aim of this review was to address the present status of the application of zirconia ceramics related to implant dentistry by analysing the published data from both in vitro and in vivo studies. Suggestions are provided for potential improvements and suitable applications of zirconia ceramics in metal-free implant dentistry. ARTICLE HISTORY

“…A lot of recent studies focus on the surface roughness of zirconia in the oral cavity. When the surface roughness of crowns is considered, the different finishing protocols determine the final roughness [20,21] The surface roughness of zirconia abutments is situated between 0,2 and 0,3µm [22]. For implants there is difference between the body part (1, 2-1,6µm) and the collar (0,3µm).…”

Although titanium is actually still the main material of choice to produce dental implants, there seems to be nowadays an obvious trend to fabricate these implants from more biocompatible materials. For the latter zirconia shows excellent conditions. Moreover, zirconia offers the dentist also the advantage to work with a more aesthetic solution. Although zirconia is already used in medicine for decades, there is still a lack of peer-reviewed research on the use of this material in dental implantology.
