The Computer Aided Design/press technique: Fabrication of zirconia-reinforced lithium disilicate restorations for treatment of extensive noncarious cervical lesions

J Esthet Restor Dent. 2022 Jul;34(5):763-768. doi: 10.1111/jerd.12882. Epub 2022 Feb 9.

Abstract

Objective: The aim of this case report is to present the CAD/Press technique; a workflow that combines digital design, milled, or 3D printed burnout molds, and a new pressable ceramic material for the treatment of extensive noncarious lesions with minimal invasive indirect ceramic restorations.

Clinical considerations: Clinical decisions from material selection, preparation design, manufacturing techniques to adhesive protocols will be discussed, as they are important factors for achieving long-term clinical success while preserving healthy tooth structure.

Clinical significance: The presented workflow aims to ease clinical decisions when restoring extensive cases with indirect restorations and show clinicians a workflow combining several techniques.

Keywords: CAD/CAM; ceramics; digital dentistry.
