[Research progress in pulpless posterior tooth restored with ceramic onlay].

Minimal invasive restoration is a common technique in the restoration of pulpless posterior teeth. The development of bonding techniques and ceramic materials in recent years has increased the use of high-strength ceramic onlay in the restoration of endodontically treated posterior teeth because of its minimal invasiveness, improved aesthetics, and low requirement of mechanical retention. This study conducts a retrospective analysis on the material, tooth preparation, bonding, and clinical considerations of ceramic onlay in endodontically treated posterior tooth.
