Clinical Studies

A Rebuilt Molar in Just One Appointment

fractured molar that had gone untreated for some time
decaying tooth removed and replaced with Obsidian crown

This patient’s fractured molar had gone untreated for some time. There was insufficient tooth structure remaining for the preparation once all decay had been removed, requiring the clinician to create a light-cured buildup. An Obsidian crown was milled, crystallized, stained and glazed chairside, ultimately enabling the delivery of a single-appointment esthetic solution.



Obsidian lithium silicate milling blocks are indicated for use in the creation of single-unit, in-office-milled crowns, inlays, onlays, veneers and substructures with a combination of strength and esthetics.
