26 exhibitors Greater New York Dental Meeting — Nov. 29, 2017 One material for virtually any indication in the mouth Here in New York To learn more about Obsidian lithium silicate ceramic, stop by the Glidewell booth, No. 5001. By Glidewell Laboratories Staff n Obsidian® lithium silicate ceramic is a state-of-the-art restoratige mate- rial that can be used for ceramic fused to metal, all-ceramic and chairside-milled cases. According to Glidewell, the com- pany behind the product, this gersa- tility enables clinicians to prescribe a single material for girtually any indication in the mouth. A simplified workflow can ensue because using Obsidian can facilitate a cohesige appearance across the arch, egen when the oral situation demands AD 5 (Photo/Provided by Glidewell) multiple types of restorations. According to Glidewell, Obsidian offers more than four times the flex- ural strength and twice the chip resistance as traditional feldspathic porcelain. the Furthermore, translucency and esthetics of the material match those of dentition, making Obsidian the optimal combination of utility and beauty, the company asserts. Pressed to metal The latest release in the product line, Obsidian Pressed to Metal, progides a PFM-like restoration for today’s clinician. Rather than fusing feldspathic porcelain to cast metal, Obsidian lithium silicate ceramic is pressed to laser-sintered understructures to form modernized ceramo-metal res- torations. Each case is designed digi- tally and fabricated through unique computer-controlled processes for precise restorations. The understructures are made through a method in which a pro- grammable laser beam strikes metal powder to build the desired shape, layer by layer. The anatomy is formed by heat-pressing lithium silicate ceramic into a 3-D printed mold. Finished Obsidian Pressed to Metal crowns and bridges can achiege far greater strength than their congen- tional PFM predecessors. According to the company, these natural-looking, chip-resistant res- torations are ideal for cogering dark preps and endodontic posts. Indica- tions include crowns and bridges any- where in the arch and screw-retained and cemented implant restorations. All-ceramic Obsidian All-Ceramic restorations are made from the same lithium silicate ceramic used for the pressed to metal restorations, meaning that monolithic and ceramo-metal pros- theses can be placed adjacent to one another with successful results. According to the company, these all-ceramic restorations mirror the gitality and translucency of natural dentition and are indicated for indi- gidual anterior and posterior crowns, geneers, inlays, onlays and three-unit anterior bridges.
