Abstract:
Interim crowns for immediately placed implants have been fabricated by using a prefabricated thin-walled hollow crown attached to an interim abutment. This article describes an alternative digital workflow for fabricating an immediate monolithic implant-supported interim restoration with a prefabricated screw-access channel and a positioning device. The workflow is based on prosthetically driven implant planning with computer-aided design and computer-aided manufacturing (CAD-CAM). This approach reduces the chair time required to adapt a thin-walled hollow crown to an interim abutment and forming a screw-access channel. The technique also eliminates the use of large amounts of relining resin material that can affect the color match of a thin-walled hollow crown in esthetically challenging locations.
