Digital Workflow Optimization for Endocrown Restorations on Root- Treated Teeth

Abstract

Endocrown restorations have become a popular solution for endodontically treated teeth, offering both functional and esthetic benefits. These restorations are particularly effective for molars due to the larger surface area of the pulp chamber, which enhances retention and stability. This article presents a clinical case of a zirconia endocrown restoration for a highly damaged mandibular molar. Utilizing a fully digital workflow, the preparation, design, and fabrication of the restoration were performed with precision, ensuring minimal tooth structure removal. Zirconia was chosen for its superior mechanical properties, including fracture resistance and durability. The challenges associated with zirconia, such as bonding reliability, were addressed through surface treatments like air abrasion and the use of 10-MDP-based chemical promoters. The patient’s outcome was both esthetically pleasing and functionally successful. This case highlights the advantages of integrating digital workflows and advanced materials in modern prosthodontic practice, while also acknowledging the need for careful selection of materials and techniques based on the individual case.
