As dental CAD/CAM systems make their way into clinics, the vision of producing indirect ceramic restorations in the practice has become reality. A 3D intraoral camera for digital impressions, intuitive design software, and a milling unit are the technologies that allow restorations to be produced on site in a short time compared with sending them to a dental laboratory.
Beyond the time advantage, the digital approach also helps save resources such as impression materials. Moreover, the need for temporary restorations is eliminated.
Material requirements for chairside production
The technical prerequisites for materials suitable for chairside production. These materials must be hard enough to ensure long service life. However, materials that are too hard are very difficult to process in milling units, especially since chairside production workflows are expected to take only a short time.
Furthermore, the material must also reproduce the outward esthetics of natural teeth to enhance the result. Chairside production is not intended for complex cases such as porcelain veneers. The term “monolithic restoration” fits well in this context. It describes a material that delivers full esthetic integration immediately, without rework. In addition, materials must provide suitable conditions for adhesive bonding, and tooth-conserving preparation techniques in particular should be prioritized.

Note: Adhesive bonding gives the best results immediately after tooth preparation.
