Zirconia is a biomaterial that is evidently used in dental ceramics and is a material of choice in contemporary restorative dentistry. It is used as a structural material for dental bridges, crowns, inserts and implants due to its compatibility, high fracture toughness and radiopacity. The most popular dental ceramics systems are silica, leucite, lithium disilicate, alumina and zirconia based materials. Zirconia is used in the form of zirconium dioxide and is known as ceramic steel. It possesses optimum properties for dental use such as superior toughness, strength, fatigue resistance, excellent wear properties and biocompatibility. Zirconium chemical and physical properties are similar to titanium and are sometimes used together in dental implants, and do not inhibit bone forming cells. Yttria is added to zirconia o form modified Yttria tetragonal zirconia polycrystal which improves physical properties of zirconia.
Zirconium oxide blocks are used by dental milling centres or labs as perfect alternatives to metals for improvement in dental technology and dental art. Dental zirconia blocks comprise of high purity and specifically engineered Yttria stabilizes zirconia powders using advance compaction techniques. Zirconia dental products made from zirconia blocks are bio-compatible and offer best results due to controlled optical and light transmission properties. Dental zirconia blocks used in dental industry removes allergic reactions, poor electrical conductor, and protects against unpleasant hot/cold sensitivity in the mouth. Dental zirconia blocks are being used for over two decades in medicine, mainly for hip replacements because they consist mainly of minerals which are found in natural bone tissue.
According to the study “Asia Dental Zirconia Block Industry Situation and Prospects Research report”, zirconia in form of zirconium dioxide, is a white coloured crystalline oxide of zirconium. Zirconia in dental medicine is used in tooth crowns for restoration of missing teeth, strengthens weak teeth and prevents tooth decay. Dental zirconium block is available in the form of nanodots, nanofluids, and nanocrystals with a white surface area. It is often coupled with yttrium oxide, or magnesia. Zirconium oxide nanoparticles are used in ceramics, pigments, porcelain glaze, artificial jewellery, abrasives, insulating, enamels and fire-retarding materials.
The leading manufactures in dental zirconia block market in Asia are Dentsply Sirona, Sagemax Bioceramics, 3M ESPE, Kuraray Noritake Dental, Bloomden Bioceramics, Mamut Dental, Zirkonzahn, Ivoclar Vivadent, GC, Pritidenta, Glidewell Laboratories, Aurident, CRYSTAL Zirconia, Aidite, Upcera Dental and Huge Dental. Geographically, dental zirconia block market in Asia is spread across China, Japan, India, Korea, Saudi Arabia and other regions. The developing countries of Asia such as India, Korea, and China are rich in zirconium dioxide resources which will surely create lucrative opportunities for the zirconium dioxide market coupled with innovative technologies in the production of coating, thermal barrier, and dental.
The use of zirconium dioxide (ZrO2) as dental ceramic is used as framework material and is made by grinding zirconia blocks for the fabrication of posterior fixed partial dentures. In Asia dental zirconia block is used in various industries such as dental, automobiles, industrial catalysts, electronics, paints, antifriction materials, fuel cells, aviation engines, jewellery, and ceramics. The major market challenge of dental zirconia block market is the increasing price of zirconia which will surely hinder its growth in the Asian market over the next few years.
