Planmeca® E4D CAD/CAM technology allows the dental team to fabricate same day dental restorations including inlays, onlays, crowns and bridges. CAD/CAM is an acronym that stands for computer-aided design/computer-aided manufacturing. This technology provides patients with durable, esthetic, well-fitting single and multiple tooth restorations in a more efficient manner. The first step in using CAD/CAM technology is tooth preparation. Next, a digital impression is taken that sends the prepared tooth’s exact dimensions into a computer. Afterwards, the computer software creates a virtual restoration replacement part for the missing areas of the tooth. The software then sends the virtual restoration data to the milling machine, where the replacement part is carved out of a solid block of ceramic or composite resin. The restoration is adjusted in the patient’s mouth and cemented or bonded in place.
