Abstract: Aerogel, calcined articles, and crystalline articles comprising ZrO2. Exemplary uses of the crystalline metal oxide articles include dental articles (e.g., restoratives, replacements, inlays, onlays, veneers, full and partial crowns, bridges, implants, implant abutments, copings, anterior fillings, posterior fillings, and cavity liner, and bridge frameworks) and orthodontic appliances (e.g., brackets, buccal tubes, cleats, and buttons).
