• Abstract

  Monolithic CAD-CAM restorations may undergo changes in their optical properties when in contact with coloring solutions. In an attempt to reverse this condition, avoiding the replacement of these restorations, the bleaching, polishing with abrasive pastes and tips and alternatively air-polishing with abrasive powders would be the possible options. No studies were found that compared the e…

  Effect of bleaching and polishing on the recovery and susceptibility to changes of the optical properties and on the surface parameters of CAD-CAM monolithic materials previously stained in coffee, AP.R

• Abstract

  The advancement of monolithic materials available in blocks for CAD/CAM has stimulated the investigation of the most varied aspects facing different challenges. However, to date, little is known about how these materials behave when exposed to gastric juice, a fact that is frequent in patients with gastroesophageal reflux and bulimia nervosa. The purpose of this study was to evaluate the …

  Effect of the gastric juice associated to toothbrushing on the long-term physical and mechanical properties of CAD/CAM monolithic materials, AP.R

• Abstract

  Currently, there is a great demand for use and supply of esthetic restorative materials, often with similar indications. A recent proposal to restore posterior teeth is the monolithic crowns. There are three restorative aesthetic materials, very competitive to each other, currently available for the fabrication of monolithic crowns to posterior teeth, which are: lithium disilicate (IPS e…

• Abstract

  Some CAD-CAM monolithic materials, when exposed in the oral cavity, are susceptible to pigmentation when in contact with food coloring. Some studies indicate that bleaching may partially or totally restore the color parameters of these previously pigmented materials. However, little is known about the effect of this procedure on the surface and mechanical properties of these materials. Th…

• Abstract

  The advance in the use of ceramic materials for monolithic restorations obtained via CAD/CAM stimulated the investigation of their mechanical properties towards different challenges. However, little is known about how the surface of these materials behave towards the action of acidic substances from extrinsic (diet) and intrinsic (gastric juice) factors. Thus, the aim of this study is to …
