Clinical fitting of a cast metal post and core obtained by means of an intraoral optical scanning (IOS) and digital workflow.

ABSTRACT

Customization of post-and-cores using computer-aided-design and computer-aided-manufacturing (CAD-CAM) requires the scanning of a pattern and the subsequent digital design. This case report describes the production of a CAD-CAM customized post-and-core designed from an intraoral scan and milled from a metal block. The use of an intraoral scanner (IOS) for post-endodontic rehabilitation could lead to a faster and more efficient CAD-CAM customized post-and-core realization. The use of a high resistance material such as metal is paramount in cases with high loss of coronal structure. The patient has been treated with bisphosphonate (BP) for years. The risk of osteonecrosis of the jaw after extraction was high.
