ĬAD/CAM materials for chairside production can be classified according to the composition of the materials ( Table 1). Benefits are easy intraoral repair with light-cured restoratives and a faster production rate since firing is not needed. Recently CAD/CAM resin composite and hybrid ceramic materials have been introduced. Indeed, digital anatomical modeling allows having minimal thicknesses avoiding the main mechanical complication of “bi-layer” systems (i.e., the chipping of coating ceramics). In chairside technology, the use of monolithic materials is preferred. Nevertheless, a post-milling crystallization is mandatory to access the final shade and the proper mechanical strength. Some of the aforementioned materials could be found in a pre-crystallized stage in order to guarantee rapid milling. Examples of these microstructures are leucite, lithium disilicate glass-ceramics, and zirconia. Then, the need for superior mechanical properties induced the development of new materials that could extend the indications of CAD/CAM restorations (onlays, crown). Feldspathic ceramics were modified in order to be used for small occlusal inlays. įor the first 15 years or so, the feldspathic ceramics (Vita Mark I, Vita Zahnfabrick, Bad Sackingen, Germany) was the only one available for CEREC. Nowadays, the main chairside systems (e.g., PlanScan, Carestream, or CEREC) are using a “full-digital workflow”, which can produce different prosthetic devices such as inlays/onlays, veneers, endo-crowns, bridge crowns, and implant abutments, to name some. The first generation of CAD/CAM machinery appeared in the market in the 1980s, and it was only able to design and produce ceramic indents. Please remember it can take some time for your bank or credit card company to process and post the refund too.Restoration production is designed using subtractive manufacturing processes, which require milling the desired restoration starting from a block of material. If approved, you’ll be automatically refunded on your original payment method. We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not. The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted, make a separate purchase for the new item.
