Abstract :
Fractures of abutment teeth under fixed prostheses pose a major prosthetic challenge, particularly when full
reconstruction is contraindicated or refused by the patient. This paper shows a clinical case study of the fabrication and
adaptation of two metallic inlaycores on teeth 21 and 12, designed to support a pre-existing anterior metal ceramic bridge.
Thanks to a precise impression of the intaglio surface of the prosthesis and rigorous laboratory fitting, it was possible to
reconstruct the endodontically treated abutments without removing or replacing the bridge. This conservative approach
demonstrates the importance of conservative management solutions for prosthetic complications that may occur while or
after achieving the prosthetic treatment, ensuring long-lasting functional and esthetic. restoration.
