Obsidian^® NOW Milling Blocks, the newest addition to the line of restorative materials for the glidewell.io^™ In-Office Solution, allow dentists to provide their patients with esthetic lithium disilicate anterior crowns straight from the fastmill.io^™ In-Office Mill.

Manufactured on the Glidewell campus, Obsidian NOW Milling Blocks undergo pre-crystallization and final crystallization stages during the production process, eliminating the need for post-mill crystallization in the dental office that is common with other glass ceramic materials. 

With a flexural strength of 476 MPa, Obsidian NOW blocks provide the esthetic benefits of a glass ceramic material while maintaining excellent strength. The monolithic composition is resistant to fracture or chipping. 

No additional staining and glazing necessary means reduced chairtime and an efficient chairside workflow calling for five steps: Scanning, designing, milling with the fastmill.io In-Office Mill, then etching. Removing the post-mill crystallization process saves about 45 minutes. After milling, the restoration is ready for final finish and polishing. After etching, Obsidian NOW can be luted using conventional cements, adhesive resin, or self-adhesive resin cements. Adhesive cement is preferred for inlays, onlays and partial crowns.  

Patients will appreciate the convenience of same-day dentistry and the esthetic characteristics of Obsidian; dentists will benefit from the efficient production process. 

Obsidian NOW is initially available in VITA^® classical shades A1, A2, A3 and B1, and priced at $130 for a three-pack of blocks, which includes five single-use burs.
