Restoration of endodontically treated antagonist molars using fully digital workflow with intraoral scanner integrated into the cad/cam system. clinical case report

Coronal rehabilitation of endodontically treated posterior teeth is always a challenge for dental surgeons. Based on the minimally invasive principles of adhesive dentistry, endocrown restorations are gaining in popularity. The current clinical case is of a female patient, 65 years old, with antagonist second molars endodontically treated and old restorations showing undesirable esthetics and breakage due to malocclusion of the prostheses. With reduced interdental spaces, lithium disilicate ceramic endocrops (IPS e.max CADin a fully digital system consisting of an Omnicam intraoral scanner and CAD/CAM Cerec was the indicated restorative treatment. The specific protocol with minimal changes to perform endocrowns was followed, which promoted an excellent marginal fit and occlusal contact without the need for adjustments. Due to the superior aesthetics and the performance of the treatment in a single session, the treatment was considered excellent by the patient. After 1 year, the clinical evaluation based on the modified FDI classification showed that the aesthetic, functional and biological properties were excellent. In this clinical case, endocrown was an effective and satisfactory treatment in the rehabilitation of the masticatory and aesthetic function of non-vital posterior teeth that required good occlusion and long-term stability.
