Implication

Randomized trial evaluates stress distribution in molars with different endocrown materials under loading, suggesting material properties significantly impact stress management.

Key Points

This study evaluates how different restorative materials affect stress distribution in endodontically treated maxillary molars under varying loading conditions.
Developed a 3D finite element model of a healthy maxillary first molar.
Generated six endocrown models using various CAD/CAM and 3D-printed materials.
Applied vertical and oblique static loads to assess stress responses.
Under vertical loading, stress distributions were low and symmetrical across all models.
Oblique loading led to increased stress concentrations, especially at cervical structures and adhesive interfaces.
Higher elastic modulus materials concentrated stress in the restoration, while lower modulus materials shifted stress to adhesive interfaces.
